The present invention relates to a control device applied to a hybrid vehicle.

  When the destination set by the user is a rechargeable place where the battery can be charged, the target remaining amount of the battery is set so that the battery is used up as much as possible when arriving at the destination. There is known a control device for a hybrid vehicle that controls the operation of the vehicle (Patent Document 1).

JP 2004-7969 A

  In the control device of Patent Document 1, it is ideal from the viewpoint of low pollution and small energy to use up the battery before the next charging, and the battery is used up when the destination is a chargeable place. . However, the user is not always charged at the destination, and the user may not want to charge depending on the situation. Therefore, if charging is not performed at a rechargeable destination, the amount of power stored in the battery will be insufficient until the subsequent charging, and the engine will be forced to travel only by the engine. The result is contrary to the ideal of small energy.

  Therefore, an object of the present invention is to provide a control device for a hybrid vehicle that can suppress deterioration in fuel consumption by directly reflecting the user's intention as to whether or not to charge the battery in the remaining amount control of the battery.

A control device for a first hybrid vehicle of the present invention includes an engine as one power source that operates by combustion of fuel, and another power source that operates by using electric power charged in the battery, and the battery includes The engine and the other power source are applied to a hybrid vehicle configured to be able to be charged from an external power source, and the remaining amount of the battery becomes the target remaining amount when arriving at a set destination. Battery remaining amount control means for controlling the operation of the battery, intention input means for inputting the user's intention as to whether or not to charge the battery at the destination as charging intention information, and a chargeable place where the battery can be charged The information is stored as information, and is set based on a field survey of the chargeable place, and information indicating the probability that the chargeable place can actually be charged is associated with the position information. And a rechargeable locations storing means for storing with the battery residual quantity control means, the user's intention to the effect that charging the battery at the destination is input by the intention input means as the charging intent information When the charging intention information is not input, the target remaining amount is reduced , and the user's intention to charge at the destination corresponds to the charging destination and the destination is the charging. When the intention input means inputs the intention information , the above-mentioned problem is solved by reducing the target remaining amount as the probability associated with the chargeable place is higher (Claim 1). According to a second aspect of the present invention, there is provided a control device for a hybrid vehicle, comprising: an engine as one power source that operates by combustion of fuel; and another power source that operates using electric power charged in a battery, Applied to a hybrid vehicle configured to be able to charge a battery from an external power source, and so that the remaining amount of the battery becomes a target remaining amount when arriving at a set destination, the engine and the other Battery remaining amount control means for controlling the operation of the power source, intention input means for inputting the user's intention as to whether or not to charge the battery at the destination as charging intention information, and charging the battery at the destination Charging that stores information indicating the probability that the user will actually charge at the destination set based on the charging history at the destination by the user who intends to Battery capacity control means, and when the user's intention to charge the battery at the destination is input as the charging intention information by the intention input means, When the user's intention to charge at the destination is input by the intention input means as the charging intention information as compared with the case where the intention information is not input, the user actually The above-mentioned problem is solved by reducing the target remaining amount as the probability of charging increases (Claim 2).

According to these control devices, when the user intends to charge the battery at the destination, the target remaining amount is lower than when the user does not intend to charge the battery. Therefore, more batteries are required until the destination is reached. Power is used. If the user does not intend to charge at the destination, the capacity of the battery is not used up even if the destination is a place where charging is possible. Thus, since the user's intention for charging the battery is reflected in the setting of the target remaining amount and the battery power is efficiently used, the fuel consumption of the engine can be suppressed and the deterioration of the fuel consumption can be suppressed. Moreover, even if the control device does not hold the position information of the chargeable place in advance, the lack of information on the chargeable place due to the user's knowledge about whether or not the destination is actually a chargeable place that can be charged. It is also possible to compensate. Therefore, the target remaining amount that reflects the user's intention is set regardless of the state of maintenance of information related to the chargeable place, so that the battery power can be used efficiently. In addition, as a premise that the intention input unit inputs the user's intention as the charging intention information, the user may express the intention in any manner. For example, an operation means such as a push button, a touch panel, or a voice recognition device is interposed between the intention input means and the user, and the operation means accepts a predetermined operation reflecting the intention of whether to charge by the user. Thus, the intention input means can input the user's intention as the charging intention information.

For example, depending on the circumstances of the rechargeable land, may not perform the charging contrary to the intention of the user have a limited number of external power supply. According to the first control device , information indicating the probability that charging can be performed in a chargeable place is stored in consideration of such uncertain factors, and the target remaining amount is reduced as the probability increases. Therefore, even if charging cannot be performed at the destination against the user's intention, the remaining amount of the battery is secured at the destination where the probability is low as compared with the high destination, so that only the engine is forced to travel thereafter. Opportunities can be reduced. Thereby, the suppression effect of fuel consumption deterioration improves. In the first control device , in order to cope with a change in the situation of each chargeable place, the probability is obtained by sequentially updating and learning the probability based on the charging history of the battery in each chargeable place. The accuracy may be increased to suit the actual situation.

Further, even if the user intends to charge at the destination, the user may forget to charge the battery after arriving at the destination due to various factors such as a long road to the destination. According to the second control device , information indicating the probability that the user actually performs charging is stored, and the target remaining amount decreases as the probability increases. Therefore, even if the user forgets to charge at the destination, if the probability of actual charging is low , the remaining amount of the battery is secured as compared with the case where it is high, so that the opportunity for driving only by the engine thereafter is reduced. be able to. Thereby, the suppression effect of fuel consumption deterioration improves. The probability that the user is actually charged depends on various factors such as the personality of the user and the environment in which the user is placed. Therefore, the probability of the user actually charging based on the charging history of the battery may be sequentially updated and learned to increase the accuracy so that the probability matches the actual situation.

First in one embodiment of the control device, and the charge possibility evaluating means for determining based on the previous SL whether the position information destination corresponding to the chargeable location, the destination of the battery of the present invention Information output means for outputting intention confirmation information for confirming the user's intention as to whether or not charging is performed, and when the destination is determined to correspond to the chargeable place by the charge availability determination means It may further comprise intention confirmation control means for controlling the information output means so that intention confirmation information is output (claim 3 ). According to this aspect, the confirmation output for confirming whether or not to charge at the destination is performed only when the destination corresponds to the chargeable place, and the destination does not correspond to the chargeable place. Sometimes no confirmation output is made. Therefore, it is possible to eliminate the annoyance of confirming output to the user every time the destination is set regardless of whether the destination is a chargeable place.

In this aspect, the intention input unit further includes an operation unit that receives an operation reflecting a user's intention as to whether or not to charge the battery at the destination on the condition that the intention confirmation information is output. mAY type the intention of whether the user charges the battery at the destination as the charging intent information in response to operation of the operating unit receives (claim 4). In this case, the operation means for accepting the user's intention accepts the operation on condition that the intention confirmation information is output, so that the user can be urged to perform the operation in a timely manner and can prevent an erroneous operation by the user. is there.

In one aspect of the first or second control device of the present invention, it further comprises fuel deterioration determination means for determining the degree of deterioration of the fuel, wherein the battery remaining amount control means is the fuel deterioration determination means at the fuel deterioration determination means. If the degree of degradation of the fuel is determined to have exceeded the allowable level, regardless of the presence of the input of the charge intention information, and set the target remaining as the consumption of the fuel by the engine is accelerated (Claim 5 ). In the case of a user who frequently travels in a short distance, the fuel is not sufficiently consumed by the engine, and the fuel is held for a longer period, so that the fuel may be deteriorated. In such a situation, when the target remaining amount is reduced and the battery power is actively used, the deterioration of the fuel proceeds. According to this aspect, when the fuel deterioration exceeds the allowable level, the target remaining amount of the battery is set so that fuel consumption is promoted regardless of the user's intention. Thereby, since fuel can be consumed at an early stage, it is possible to stop the progress of fuel deterioration.

In one aspect of the first or second control device of the present invention, extending the life of the battery by not using up the capacity of the battery, and suppressing fuel consumption deterioration by using up the capacity of the battery; Is established as a trade-off relationship, the life extension is determined based on the fact that the battery life is nearing the time for replacement of the battery in order to suppress the deterioration of fuel consumption of the hybrid vehicle. The battery remaining amount control means is provided with whether or not the charging intention information is input when it is determined by the life extension necessity determination means that it is necessary to extend the life of the battery. not, may be set the target remaining not to use up the capacity of the battery (claim 6). Rather than using the battery and charging it repeatedly, using it so that the remaining amount of the battery changes to about half of the total capacity can reduce the damage to the battery and extend the life. It is desirable to extend the life of the battery so that when the battery is nearing its end of life, the battery can be replaced prior to avoiding sudden battery failure. According to this aspect, when it is necessary to extend the life of the battery, the target remaining amount is set so as not to use up the capacity of the battery. As a result, damage to the battery can be reduced and the life of the battery can be extended.

  In addition, the motor generator which has the function as an electric motor and the function as a generator is also contained in the other power source which concerns on this invention.

  As described above, according to the present invention, when the user intends to charge the battery at the destination, the target remaining amount is lower than when the user does not intend to charge the battery. More battery power is used. If the user does not intend to charge at the destination, the capacity of the battery is not used up even if the destination is a place where charging is possible. As a result, the user's intention for charging the battery is reflected in the setting of the target remaining amount, and the battery power is efficiently used. Therefore, fuel consumption of the engine can be suppressed and fuel consumption deterioration can be suppressed.

  FIG. 1 is a conceptual diagram showing a main part of a hybrid vehicle to which a control device according to an embodiment of the present invention is applied. The hybrid vehicle 1 includes an engine 2 that is an internal combustion engine as one power source, and a motor generator (MG) 3 as another power source. The engine 2 uses gasoline as fuel and is configured as a gasoline engine that operates by combustion of gasoline. The MG 3 is connected to the battery 4 via an inverter (not shown) and operates using the electric power charged in the battery 4, while the electric power generated according to the situation can be charged in the battery 4. The battery 4 is connected to an SOC sensor 5 for detecting the amount of stored electricity, in other words, the remaining amount of the battery. The hybrid vehicle 1 is provided with an external charging device 6 so that the user can charge the battery 4 by connecting the external charging device 6 and an external power source (not shown) installed in a house or the like. It is configured. Such a hybrid vehicle 1 is sometimes called a plug-in hybrid vehicle in distinction from a vehicle that cannot be charged by an external power source. The output shafts of the engine 2 and the MG 3 are connected to the power split mechanism 7, and the outputs of the engine 2 and MG 3 are transmitted to the drive wheels 9 via the power split mechanism 7 and the transaxle 8. In the hybrid vehicle 1, the driving force distribution between the engine 2 and the MG 3 is operated by the power split mechanism 7 to perform proper driving.

  The operations of the engine 2, the MG 3 and the power split mechanism 7 are controlled by an electronic control unit (HVECU) 10. The HVECU 10 is configured as a computer for appropriately controlling the operation of the hybrid vehicle 1. In addition to receiving input signals from various sensors such as the SOC sensor 5 described above, the HVECU 10 provides a user who is a driver of the hybrid vehicle 1. On the other hand, information from the navigation device 11 for guiding the route to the destination is also input. Although there are many peripheral devices such as sensors connected to the HVECU 10, their illustration and description are omitted here. The navigation device 11 incorporates position detection means such as a GPS and a gyro sensor (both not shown) for grasping the current location of the hybrid vehicle 1, and calculates a route from the current location to the destination set by the user and its distance. Can be output. The navigation device 11 includes a monitor device 12 for displaying an image for guiding a route to a destination set by the user while showing the current position detected by the position detection means on a map held in the internal storage device, Are connected to a speaker 13 for providing the information to the user by voice. The monitor device 12 is configured as a touch panel that can accept various operations such as a destination input operation by the user by touching the screen. When the operation is accepted, a signal corresponding to the operation is transmitted to the navigation device. 11 is input.

  The HVECU 10 obtains the route and travel distance from the current position to the destination set by the user from the navigation device 11, and the engine 4 so that the remaining amount of the battery 4 becomes the target remaining amount when the destination is reached. 2 and MG3 are controlled. In the following description, this control is referred to as SOC control. 2 and 3 are flowcharts showing an example of a control routine for SOC control. FIG. 2 shows the main routine and FIG. 3 shows a subroutine. The hybrid vehicle 1 is characterized by a target remaining amount setting method by the HVECU 10. As shown in FIG. 2, in step S1, the HVECU 10 acquires a route from the current location to the destination set by the user and the distance thereof based on the signal from the navigation device 11. Next, in step S2, it is determined whether or not the destination is a rechargeable place where a battery such as a home or work place equipped with an external power source can be charged. The HVECU 10 is provided with a storage device (not shown) such as a ROM or a hard disk, and the storage device stores information relating to the rechargeable place shown in FIG. As is clear from FIG. 4, the position information stores n pieces of position information of rechargeable places specified by latitude and longitude, and the chargeability described later is quantified for each of the position information. The associated information is stored in association with each other. The HVECU 10 searches the rechargeable locations in FIG. 4 for a match with the destination set by the user. As a result of the search, if the destination corresponds to a chargeable place, the process proceeds to step S3. If not, the process skips step S3 and step S4 and proceeds to step S5.

  In step S <b> 3, the HVECU 10 controls the navigation device 11 so that the intention confirmation information for confirming the intention of the user whether or not to charge the battery 4 at the destination is output from the monitor device 12. FIG. 5 shows an output example of intention confirmation information. As shown in the figure, the monitor device 12 displays a character “Do you want to charge at the destination?”, And a predetermined sound is output from the speaker 13 simultaneously with the display. Furthermore, the monitor device 12 displays “charge” and “do not charge” on the screen, and can accept a touch operation that the user touches one of these displays on condition that the intention confirmation information is output. It has become. That is, the user's touch operation on the monitor device 12 corresponds to an operation reflecting the user's intention as to whether or not to charge the battery 4 at the destination.

  In step S4, it is determined whether or not there is a touch operation by the user. If there is no operation, the process returns to step S3, and output of intention confirmation information is continued until the touch operation by the user is performed. If there is a touch operation, the process proceeds to step S5. When the user performs a touch operation, the navigation device 11 outputs the user's intention as charging intention information in accordance with the operation, and the charging intention information is input to the HVECU 10. The charging intention information is treated as a numerical value, and includes a numerical value corresponding to the intention of the user to charge and a numerical value corresponding to the intention of the user not to charge.

  In step S5, the target remaining amount used in the SOC control is set. Although detailed description of setting of the target remaining amount will be described later, the setting is intended for the battery 4 when the user's intention to charge the battery 4 at the destination is input as the charging intention information in the navigation device 11. The main feature is that the target remaining amount is reduced as compared with the case where charging intention information indicating that charging is not performed on the ground is input. When the target remaining amount is set in step S5, in subsequent step S6, the HVECU 10 causes the engine 2 and the MG3 to become the target remaining amount set in step S5 when the remaining amount of the battery 4 reaches the destination. To control the operation.

  Here, details of the target remaining amount setting process in step S5 shown in FIG. 2 will be described. First, as a premise for specifically explaining this process, the concept regarding the target remaining amount will be briefly described with reference to FIG. FIG. 6 shows an example of a change in the charged amount (SOC) of the fully charged battery 4 with respect to the travel distance of the hybrid vehicle 1. In general, it is known that using the battery so that the remaining amount of the battery changes at about half of the total capacity reduces damage to the battery and extends the life rather than repeatedly using the battery and using it repeatedly. However, in the case of a hybrid vehicle, if the battery is used so that the remaining amount is about half as in the latter case, the load on the engine increases as much as the power consumption of the battery decreases, resulting in a deterioration in fuel consumption. In other words, in the case of a hybrid vehicle, there is a tradeoff between extending the battery life and suppressing fuel consumption deterioration. Therefore, in a general hybrid vehicle that cannot be charged from an external power source, the remaining amount of the battery is controlled so that the battery is not used up while running.

  Since the hybrid vehicle 1 of the present embodiment is a plug-in type, even if the battery is used up, it can be charged from an external power source, so that an improvement in fuel consumption can be pursued. Therefore, as shown in FIG. 6, the final state in which the battery 4 is used up at the time of arrival at the destination is made as long as possible for the period of transition with the intermediate remaining amount fSOC1 friendly to the battery 4 until the arrival at the destination A. Adopting the strategy of remaining amount fSOC2 is ideal for improving fuel efficiency while suppressing the influence on the battery life. However, since it is the user who charges the battery 4, the user's convenience should be considered. In addition, taking into account various factors such as the condition of the battery 4 and the engine 2, the priority of extending the life of the battery and suppressing the deterioration of fuel consumption is determined, and the target remaining amount upon arrival at the destination is set. It is important to improve practicality. Based on such a concept, the hybrid vehicle 1 uses the following formula 1 to set the target remaining amount SOCtrg when the destination arrives.

      SOCtrg = fSOC2 × K + fSOC1 × (1−K) 1

  Here, fSOC2 <fSOC1. K is a variable that satisfies 0 ≦ K ≦ 1 and indicates the possibility (probability) that the battery 4 is actually charged. The higher the possibility, the larger the value of K.

  As can be understood from Equation 1, the target remaining amount SOCtrg decreases as the value of K increases. In other words, the higher the possibility of charging, the lower the target remaining amount, and priority is given to improving fuel consumption. Therefore, the target remaining amount corresponding to the situation can be determined by appropriately setting the value of K according to the situation.

  FIG. 3 shows an example of a target remaining amount setting routine. First, the HVECU 10 determines the degree of deterioration of the fuel used in the hybrid vehicle 1 in step S51. If it is determined that the degree of deterioration has exceeded the allowable level, the process proceeds to step S57. If not, the process proceeds to step S52. move on. Since the fuel deterioration progresses with the elapsed time since refueling, in this determination, the degree of deterioration is estimated based on the elapsed time from the most recent refueling time, the amount of fueling, and the integrated value of fuel consumption. When the value exceeds a preset threshold value, the degree of deterioration exceeds the allowable level.

  In step S52, it is determined whether it is necessary to extend the life of the battery 4. If there is such a need, the process proceeds to step S57, and if not, the process proceeds to step S53. The necessity of extending the life of the battery 4 is determined based on whether or not the replacement time of the battery 4 is approaching.

  In step S53, it is determined whether or not the charging intention information indicating that the user charges at the destination is input from the navigation device 11. If the charging intention information is input, the process proceeds to step S54. If the charging intention information indicating that the user does not charge at the destination is input, the process proceeds to step S57.

  Thereafter, the value of the variable K is calculated by executing the processing from step S54 to step S57, and the target remaining amount is set by substituting the value of the variable K into equation 1 in step S58. The amount setting process ends.

  Next, the calculation of the variable K will be described in detail. If an affirmative determination is made in step S51 and step S52, 0 (zero) is substituted for variable K in step S57. Thereby, regardless of the user's intention, the target remaining amount is large, specifically equal to fSOC1. Therefore, since the burden on the engine 2 increases, the target remaining amount is set so that fuel consumption is promoted regardless of the user's intention. In other words, since damage to the battery 4 is reduced, the target remaining amount is set so that the life of the battery 4 is extended regardless of the intention of the user.

  If an affirmative determination is made in step S53, that is, if there is charging intention information indicating that the battery 4 is to be charged, the HVECU 10 sets a variable k1 (0 ≦ k1 ≦ 1) indicating that the user may forget to charge in step S54. ) Is read from the storage device. The value of the variable k1 is sequentially updated based on the past charging history of the battery 4. That is, the value of the variable k1 is smaller for a user who has few opportunities to forget to charge than a user who has many opportunities. Needless to say, 1-k1 means that the user may actually charge.

  In the subsequent step S55, the HVECU 10 stores information on the chargeable place of FIG. 4 stored in the storage device, the value of the variable k2 (0 <k2 ≦ 1) indicating the possibility of actual charge at the chargeable place as the destination. Read by reference. The value of this variable k2 is set by a field survey such as the number of external power sources and the degree of congestion in each chargeable area. Changes in the situation of each chargeable place can be dealt with by periodically rewriting information. In addition, in order to respond flexibly to a change in the situation of each chargeable place, the value of this variable k2 can be sequentially updated and learned based on the charge history of the battery in each chargeable place.

  Next, in step S56, the value of variable K1 is determined by substituting the values of variable k1 and variable k2 read in the above processing into the following equation (2).

      K = 1 × (1-k1) × k2 ............ 2

  As is clear from Equation 2, the possibility that the user forgets to charge and the possibility that the user can charge in a chargeable place is considered and the possibility that the charging is actually performed is estimated. Can be determined. Further, as is clear from the above-described formulas 1 and 2, the target remaining amount decreases as the possibility that the user actually charges is higher, and there is a possibility that the user can actually charge in the chargeable place. The higher the value, the lower the target remaining amount.

  According to the above embodiment, when the user does not intend to charge the battery 4 at the destination, that is, when the charging intention information indicating that the battery 4 is not charged is input, the variable K becomes zero and the target remaining amount is fSOC1. Become. Therefore, after that, traveling by only the engine 2 is not forced. On the other hand, when there is a user's intention to charge the battery 4 at the destination, that is, when charging intention information for charging is input, the variable K becomes larger than zero and the target remaining amount is lower than fSOC1. To do. Therefore, more battery power can be used until the destination is reached, so that fuel efficiency is improved.

  In the above embodiment, the navigation device 11 corresponds to the intention input means according to the present invention, the monitor device 12 and the speaker 13 correspond to the information output means according to the present invention, and the monitor device 12 corresponds to the operation means according to the present invention. Further, the HVECU 10 corresponds to each of the chargeable ground storage means and the chargeability storage means according to the present invention. The HVECU 10 executes step S2 of FIG. 2 as chargeability determination means according to the present invention, and executes step S3 and step S4 of FIG. 2 as intention confirmation control means according to the present invention. By executing steps S5 and S6 and steps S51 to S58 in FIG. 3 as the battery remaining amount control means according to the present invention, by executing step S51 in the same figure as the fuel deterioration determining means according to the present invention, By performing step S52 in the figure, each functions as a life extension necessity determining unit according to the present invention.

  However, the present invention is not limited to the above embodiment, and can be realized in various forms within the scope of the gist of the present invention. In the process of FIG. 2, it is determined in step S2 whether or not the destination is a chargeable place, and intention confirmation information is output only when the destination is a chargeable place. Instead, the intention confirmation information may be output regardless of whether or not the destination is a chargeable place by omitting the process of step S2. In this case, the charging obtained from the actual experience of the user even if the information on the chargeable place to be held by the control device is not yet developed or the information on the chargeable place is not held on the control device side. The intention of whether or not to charge based on the possible locations can be reflected in the setting of the target remaining amount. Further, Step S51, Step S52, Step S54 and Step S55 in FIG. 3 are arbitrary configurations, and it is also possible to implement the present invention by omitting all or part of them.

  The intention input means may not be a so-called navigation device. That is, as long as the route to the destination and the distance can be calculated, there may be no function for guiding the route to the user. In the above embodiment, an example is shown in which the user sets the destination each time, but the method for setting the destination is not particularly limited. When the hybrid vehicle according to the present invention is used for an application in which a predetermined route is traveled and a place for charging is determined, for example, a transportation system or a regular flight in a factory, when the operation of the hybrid vehicle is started in advance. It is also possible to confirm whether charging is possible at a set destination.

  Moreover, it is not essential to provide the information output means according to the present invention, and the intention confirmation information output by the information output means may be implemented by any means that appeals to the human senses. Further, in the above-described form, the timing at which the operation means receives the operation from the user is associated with the output of the intention confirmation information. However, the operation from the user may be received regardless of the output. For example, a switch such as a push button that can be always operated may be used. Further, there is no restriction on the operation performed by the user, and a voice recognition device may be provided as an operation means so that the user can perform the operation by voice. In the above embodiment, the monitor device 12 functions as an information output unit and an operation unit by configuring the monitor device 12 as a touch panel. However, these units may be realized by separate devices.
