International Publication No. 2012/176316

In the above control device, it is conceivable to add a mode (state) that enables the drive power of the vehicle to be turned off while maintaining the neutral range. This makes it possible to move the vehicle, for example, when the vehicle is being washed while being towed, or in the vehicle production process. However, for example, in a vehicle in which the vehicle can be started on the condition that the parking range is selected, if an erroneous operation signal is output from the shift range selection operating body, switching to a shift range other than the neutral range is prioritized. Therefore, even if the parking range is operated, the vehicle cannot be put into the parking lock range state, which causes the vehicle to be unable to start.

The present invention has been made in the context of the above circumstances, and an object of the present invention is a mode (state) that enables a part of a vehicle power source, for example, a drive power source to be turned off while maintaining a neutral range. ) Is also added, it is an object of the present invention to provide a vehicle control device capable of putting the vehicle in the parking lock state when an erroneous signal is output from the shift range selection operating body.

An auto that selects the parking range and stops the vehicle power supply based on the shift operation device including the above, the vehicle power supply operating body operated for switching the vehicle power supply, and the power off operation by the vehicle power supply operating body. A vehicle control device including a park determination means, wherein (b) the operation of the shift range selection operation body is prioritized over the operation of the parking range selection operation body to select the shift range. The means, the second shift range determination means for selecting the shift range by giving priority to the operation of the parking range selection operation body over the operation of the shift range selection operation body, and the shift range selection operation body were maintained in the neutral position. When the power-off operation is performed in this state, or when the shift range selection operation body is set to the neutral position a predetermined number of times within a predetermined time after the power-off operation, the shift range and the parking range are set. It has a special mode determining means for determining a transition to a special mode for maintaining a power state that enables selection, and (c) when a transition to the special mode occurs, the second shift range determining means When the shift range is selected and the shift to the special mode does not occur, the shift range is selected by the first shift range determining means.

According to the first invention, a shift operation device including a shift range selection operation body operated to select a shift range other than the parking range and a parking range selection operation body operated to select the parking range. And the vehicle power supply operating body operated for switching the vehicle power supply, and the auto park determination means for selecting the parking range and stopping the vehicle power supply based on the power off operation by the vehicle power supply operating body. A vehicle control device including a first shift range determining means for selecting the shift range by giving priority to the operation of the shift range selection operation body over the operation of the parking range selection operation body, and the parking range selection operation body. The second shift range determination means for selecting the shift range in preference to the operation of the shift range selection operation body and the power off operation are performed while the shift range selection operation body is maintained in the neutral position. If, or after the power-off operation, the shift range selection operation body is set to the neutral position a predetermined number of times within a predetermined time, the power state that enables selection between the shift range and the parking range is maintained. It has a special mode determining means for determining the transition to the special mode, and when the transition to the special mode occurs, the shift range is selected by the second shift range determining means and the shift to the special mode is performed. If no shift occurs, the shift range is selected by the first shift range determining means. As a result, even when a mode (state) that enables a part of the vehicle power supply to be turned off while maintaining the neutral position is added, an erroneous signal is output from the shift range selection operating body. In addition, the vehicle can be in the park lock position.

Hereinafter, examples of the present invention will be described in detail with reference to the drawings. In the following examples, the drawings are appropriately simplified or deformed, and the dimensional ratios and shapes of each part are not necessarily drawn accurately.

FIG. 1 is a diagram illustrating a schematic configuration of a power transmission path from the engine 12 to the drive wheels 14 constituting the vehicle 10 to which the present invention is applied, and also is a diagram for controlling the parking lock device 16 and the like. It is a block diagram explaining the main part of the control system provided in. In FIG. 1, the vehicle 10 is a hybrid vehicle including an engine 12 and an electric motor M as a driving force source. The present invention is applicable not only to a hybrid vehicle but also to a vehicle having only an electric motor M or an engine as a driving force source. Further, the vehicle 10 includes a parking lock device 16, a transmission 18, a shift operation device 30, a charging device 50 for driving the electric motor M, and the like, and a shift position related to the running of the vehicle 10, that is, a shift position of the transmission 18. The shift-by-wire (SBW) system that electrically switches between the two is adopted. Further, the transmission 18 is preferably used for an FF (front engine / front drive) type vehicle that is horizontally placed in a vehicle 10, for example, and powers an engine 12 that is an internal combustion engine as a driving force source for traveling. From the output gear 22 as the output rotating member of the transmission 18 constituting one of the counter gear pairs 20, the counter gear pair 20 as the power transmission device, the final gear pair 24, the differential gear device (differential gear) 26, and the pair. It is transmitted to the pair of drive wheels 14 via the axles 28 and the like in sequence. The transaxle (T / A) is composed of the transmission 18, the counter gear pair 20, the final gear pair 24, the differential gear device (differential gear) 26, and the like.

Further, the vehicle 10 is provided with an electronic control device 90 including a vehicle shift operation device that controls the operating state of the parking lock device 16, the shift range, and the like. The electronic control device 90 is configured to include, for example, a so-called microcomputer provided with a CPU, RAM, ROM, an input / output interface, etc., and the CPU follows a program stored in the ROM in advance while using the temporary storage function of the RAM. By performing signal processing, hybrid drive control such as output control of the engine 12 and drive control of the electric motor M, shift control of the transmission 18, shift position switching control of the transmission 18 using the shift-by-wire method, and a parking lock device 16 such as switching control of the operating state is executed.

The electronic control device 90 is provided with, for example, a shift lever position signal Psh from the shift sensor 36, which is a position sensor for detecting the operation position of the shift lever 32 (corresponding to the shift range selection operation other body of the present invention), by the user. In the park switch (P-switch) 34 (corresponding to the parking range selection actuator of the present invention) for switching the shift range of the transmission 18 from a non-P range other than the parking range (P range) to the P range by being operated. FIG. 2 of FIG. 2 shows a parking lock device 16 for operating or releasing a park switch signal Pon indicating a switch operation and a parking lock (P lock) to switch the shift range of the transmission 18 between the P range and the non-P range. A rotation amount signal Ro indicating the rotation amount of the shift control actuator 60, and a vehicle power switch 40 for switching the power supply switching state of the vehicle 10, that is, the power supply state, which is operated by the user (corresponding to the vehicle power supply operating body of the present invention). Power switch signal SWon indicating the switch operation in), brake operation signal Bon indicating the brake on state from the brake switch 42 indicating that the foot brake pedal (not shown) for detecting the operation of the normal brake has been operated, output. The rotation speed Now, which is a signal from the output rotation sensor 44 indicating the rotation of the gear 20, the charge capacity signal SOC indicating the charging state of the charging device 50 from the battery sensor 52, and the like are supplied, respectively.

The shift lever 32 is arranged near the driver's seat, for example, and is operated to a plurality of shift positions. The shift lever 32 includes a momentary type shift lever 32 in which the shift lever 32 automatically returns to a preset neutral position when the operation of the shift lever 32 by the driver is released. .. The momentary type is a type in which the shift lever 32 automatically returns to the preset neutral position when the operation of the shift lever 32 by the driver is released. Therefore, the shift range is a controlled shift state of the vehicle determined based on the operation of the driver such as the shift lever 32 and the P switch 34, and does not necessarily match the operation position of the shift lever 32.

The vehicle power switch 40 is, for example, an automatic return type push button switch that is arranged near the driver's seat and is operated to switch the power supply state of the vehicle 10. Therefore, in the present embodiment, the switch operation in the vehicle power switch 40 is the pressing operation of the push button switch, and the power switch signal SWon is output only during this pressing operation, that is, the power switch signal SWON is in the ON state. It is said that. Further, by pressing the vehicle power switch 40, a power-on state for enabling vehicle running, a power-off related to vehicle running, and a power supply not related to vehicle running are turned on to perform some functions of the vehicle 10. For example, the power is partially turned on (the parking lock device can be operated) to enable the operation of an audio device, a car navigation device, etc. (not shown), and the vehicle power is turned off in order to turn off all the powers.

Further, from the electronic control device 90, for example, an engine output control command signal Se for output control of the engine 12, a motor control command signal Smg for drive control of the electric motor M in the transmission 18, and shift control of the transmission 18 Signals such as a hybrid control command for switching the shift position of the transmission 18 and a shift range switching control command for switching the shift position of the transmission 18, and a P lock display control command signal for operating the P position indicator lamp 38 to display the P lock state. , P switching control command signal Sp for switching control of the parking lock device 16 and the like are output respectively.

The parking lock device 16 shown in FIG. 2 has a shaft 72 that is rotationally driven by a shift control actuator 60 (hereinafter referred to as an actuator), and a P-lock position and a parking position corresponding to the parking position by rotating along with the rotation of the shaft 72. The detent plate 74 that functions as a P-lock positioning member for switching between non-P-lock positions that do not correspond to the above, and a rod 76 that operates with the rotation of the detent plate 74, for example, are concentrically fixed to the output gear 22 of the transmission 18. The parking gear 78 (see FIG. 1) that rotates in conjunction with the drive wheel 14, the parking lock pole 80 for locking the parking gear 78, and the detent plate 74 are restricted from rotating to fix the shift position. It is equipped with a detent spring 82, a roller 84, and the like.

FIG. 2 shows a non-P-locked state. When the shaft 72 is rotated in the direction of arrow C from this state, the rod 76 is pushed in the direction of arrow A, and the parking lock pole 80 is pushed up in the direction of arrow B. As the detent plate 74 rotates, the roller 84 of the detent spring 82, which was in the non-P-lock position, gets over the mountain 88 and moves to the P-lock position. When the detent plate 74 rotates until the roller 84 reaches the P lock position, the parking lock pole 80 is pushed up by the taper member 86 to a position where it meshes with the parking gear 78. As a result, the rotation of the parking gear 78 is mechanically blocked.

Returning to FIG. 1, a functional block explaining a main part of electrical control is shown inside the electronic control device 90. The special mode determining means 100 determines the transition to the special mode by the operation of the shift lever 32 of the driver and the operation of the vehicle power switch 40, which are predetermined. The auto park determining means 102 determines and executes the park lock when the normal mode, that is, the special mode is not entered and the vehicle power switch 40 is operated. When the special mode determining means 100 determines that the first shift range determining means 104 is not a transition to the special mode but is a normal mode, the shift range based on the operation of the shift lever 32 is based on the operation of the park switch 34. Judgment is given priority over the shift range, and switching of the shift range is determined and executed. Further, when the special mode determining means 100 determines the shift to the special mode, the second shift determining means 106 gives priority to the parking range based on the operation of the park switch 34 over the shift range based on the operation of the shift lever 32. Judgment, judgment of shift range switching, and execution.

FIG. 3 shows the power state, shift position, and park lock of the vehicle 10 when the special mode is not selected, that is, when the park switch 34, the shift lever 32, and the vehicle power switch 40 are operated in the normal mode. It is a time chart which showed an example of operation. When the normal mode is selected by the special mode determining means 100, the first shift determining means 104 is selected. At the time of t1, the shift lever 32 is operated to the D position, the D signal is output from the shift sensor 36, the park switch 34 is operated, and the P switch signal Pon is output from the shift operation device 30. Since the first shift range selection means 104 selects the shift range based on the operation of the shift lever 32 with priority over the parking range based on the operation of the park switch 34, the shift range is changed from the N range to the D range. At the time of t3, the operation signal SWon of the vehicle power switch 40 is input, that is, the operation is performed by the driver who turns off the vehicle power, and the auto park determination means 102 switches the shift range to the P range and the vehicle power. We are implementing an auto park that shifts to the off state. At the time of t4, the vehicle power is turned off.

FIG. 4 is a time chart showing the operation for shifting to the special mode. The vehicle 10 has a shift range of the D range, a power supply state of the power-on state that enables the vehicle 10 to travel, and a normal mode. At t11, the N signal is output by operating the shift lever 32. Since it is in the normal mode, the first shift determination means 104 is selected by the special mode determination means 100, and the shift range is shifted from the D range to the N range by the first shift determination means 104. In addition, the power supply state is maintained in the power on state. At the time of t12, the shift lever 32 is maintained in the N range and the vehicle power switch 40 is operated, so that the special mode determining means 100 determines the transition to the special mode. After t13, the special mode is set, and the special mode determination means 100 selects the second shift range determination means 106 and invalidates the auto park by the auto park determination means 102. Further, the special mode determining means 100 switches the power supply state of the vehicle from the power supply on state to the power supply partial on state. The second shift range determining means 106 selects the operation of the park switch 34 in preference to the operation of the shift lever 32. Further, the shift range is maintained in the N range even when the shift lever 32 is operated. At the time of t14, the shift lever 32 is operated and the D signal is output, but the shift range is maintained in the N range. When the park switch 34 is operated at the time of t15, the second shift range determining means 106 switches the shift range from the N range to the P range.

FIG. 5 is a flowchart showing which of the shift lever 32 and the park switch 34 is determined first when the shift lever 32 and the park switch 34 are operated in the normal mode. In the normal mode, it is determined whether or not the shift lever 32 has been operated in step S10 corresponding to the function of the first shift range determination means 104 (hereinafter, step is omitted). If the determination in S10 is affirmed, the shift range is set based on the shift lever operation signal Psh of the shift lever 32 in S30 corresponding to the function of the first shift range determination means 104. If the determination in S10 is denied, it is determined whether or not the P switch signal Pon of the park switch 34 is input in S20 corresponding to the function of the first shift range determination means 104. If the determination in S20 is denied, the determination from S10 is repeated. If the determination in S20 is affirmed, the shift range is set to P, that is, the parking lock in S40 corresponding to the function of the first shift range determination means 104.

In the normal mode of FIG. 5, when the P switch signal Pon of the park switch 34 is continued for some reason, for example, the park switch 34 is stuck due to an input circuit abnormality of the ECU that makes a shift determination, an internal contact abnormality, or the like, due to the driver. Even if the P signal continues due to holding the park switch, holding the park switch due to hitting something such as luggage, or returning failure due to an increase in the sliding resistance of the park switch 34, the shift lever 32 can be operated to shift to a shift range other than the P range. It becomes possible to set.

FIG. 6 is a flowchart showing the operation of the electronic control device 90 when the automatic car wash mode, that is, the special mode is selected. In S50 corresponding to the function of the special mode determining means 100, it is determined whether or not the special mode is selected. When this S50 determination is denied, that is, when it is determined that the normal mode is selected instead of the special mode, the normal mode shown in S10 to S40 of FIG. 5 is used in S100 corresponding to the first shift range determination means 104. The shift range is set in. The flow corresponding to S10 to S40 in this S100 is shown as a setting of the normal mode for simplification. When the determination of S50 is affirmed, it is determined whether or not the P switch signal Pon of the park switch 34 is input in S60 corresponding to the function of the second shift range determination means 104. When the determination in S60 is denied, it is determined whether or not the shift lever 32 has been operated in S70 corresponding to the function of the second shift range determination means 106. If the determination in S70 is affirmed, the shift range is set to the N range in S90 corresponding to the function of the second shift range determination means 106, and the determination in S60 is repeated. If the determination in S70 is denied, the determination in S60 is repeated. If the determination in S60 is affirmed, the shift range is set to P, that is, the parking lock in S80 corresponding to the function of the second shift range determination means 106.

In the special mode of FIG. 4, when the shift position Psh of the shift lever 32 is continued for some reason, for example, an abnormality of the shift sensor 36 that detects the position of the shift lever 32, an abnormality of the input circuit of the ECU that determines the shift, and a shift. It is possible to switch to the P range even when the operation output of the operation position signal Psh of the shift lever 32 continues due to, for example, hanging the bag to the lever 32 or a poor return of the shift lever 32 due to an increase in sliding resistance. It is possible to turn on the power to enable the vehicle to travel even in the vehicle for turning on the power to enable the vehicle to travel on condition that the P range is set.

FIG. 7 shows an example of the operation of switching from the normal mode to the special mode shown in the time chart of FIG. 4, the flow in the normal mode shown in the flowchart of FIG. 5, the flow in the special mode shown in the flowchart of FIG. 6, and the like. It is a flowchart shown in combination.

In FIG. 7, in S210 corresponding to the function of the special mode determination means 100, it is determined whether or not the power off operation is performed by the operation of the vehicle power switch 40. When the determination of S210 is denied, the shift range in the normal mode shown in S10 to S40 of FIG. 5 is set in S250 corresponding to the function of the first shift range determination means 104, and the determination from S210 is made. It is repeated. When the determination in S210 is affirmed, it is determined in S220 corresponding to the function of the special mode determination means 100 whether or not the holding operation to the N range has been performed, that is, whether or not the operation signal Psh to the N range has been output. NS. When the determination in S220 is denied, the shift range is set to the P range, that is, the auto park in S240 corresponding to the function of the auto park determination means 102. Further, the vehicle power supply is stopped in S270 corresponding to the function of the auto park determination means 102. If the determination in S220 is affirmed, in S230 corresponding to the function of the special mode determination means 100, the auto park in which the P range is set in accordance with the power off operation is invalidated. Further, in S260 corresponding to the function of the special mode determination means 100, the shift range is set to the N range. Further, in S280 corresponding to the function of the special mode determination means 100, a power supply partial on state (parking lock device operation is possible) in which a part of the power supply is turned off is selected. A special mode is selected in S290 corresponding to the function of the special mode determining means 100. After that, that is, in S300 to 330 corresponding to the function of the second shift range determination means 106, the same flow as in S60 to S90 of FIG. 6 is executed.

According to this embodiment, a shift lever 32 operated to select a shift range other than the P range, a shift operation device 30 including a park switch 34 operated to select the P range, and a vehicle power supply. An electronic control device for a vehicle 10 including a vehicle power switch 40 operated for switching and an auto park determination means 102 for selecting a P range and stopping the vehicle power based on a power off operation by the power switch 40. 90, the first shift range determining means 104 for selecting the shift range by giving priority to the operation of the shift lever 32 over the operation of the park switch 34, and shifting the operation of the park switch 34 with priority over the operation of the shift lever 32. When the power off operation is performed while the second shift range determining means 106 for selecting the range and the shift lever 32 are maintained in the neutral position, the power state is maintained so that the shift range and the parking range can be selected. It has a special mode determining means 100 for determining the transition to the special mode, and when the transition to the special mode occurs, the shift range is selected by the second shift range determining means 106, and the transition to the special mode occurs. In this case, the second shift range determining means 106 selects the shift range, and if the shift to the special mode does not occur, the first shift range determining means 104 selects the shift range. As a result, even when a mode (state) that enables a part of the vehicle power supply to be turned off while maintaining the neutral range is added, if an erroneous signal is output from the shift lever 32, the vehicle It is possible to put 10 in the parking lock state.

Next, another embodiment of the present invention will be described. In the following description, parts common to each other in the examples are designated by the same reference numerals, and the description thereof will be omitted.

In the first embodiment, when the power off operation is performed while the shift lever 32 is maintained in the neutral range, the mode shifts to the special mode. This embodiment is different from the above-described embodiment in that the shift lever 32 is switched to the neutral position a predetermined time, for example, three times within a predetermined time ta after the vehicle power is turned off to shift to the special mode. There is.

FIG. 8 is a time chart showing the operation in this embodiment for shifting to the special mode. The vehicle 10 is in the normal mode, and the first shift range determining means 104 is selected. At the time of t20, the shift lever 32 is operated to the D position, the D signal is output from the shift sensor 36, the park switch 34 is operated, and the P switch signal Pon is output from the shift operation device 30. Since the first shift range selection means 104 selects the operation of the shift lever 32 with priority over the operation of the park switch 34, the shift range is changed from the N range to the D range. At the time of t22, the operation signal SWon of the vehicle power switch 40 is input, that is, the operation by the driver who turns off the vehicle power is performed. At the time of t23, the auto park determining means 102 switches the shift position to the P position, and at the same time, performs an auto park in which the vehicle power supply is switched to the off state after a lapse of a predetermined time ta from the time of t23. When the shift lever 32 is operated to the N position three times within a predetermined time ta from the time of t23, the special mode determining means 100 determines the transition from the normal mode to the special mode. In FIG. 8, since the elapsed time from t23 to t29 is within the predetermined time ta, the transition to the special mode is determined. At t24, the shift lever 32 is operated to the N position, and the shift range is changed from the P range to the N range. At the time of t26, the vehicle power switch 40 and the shift lever 32 are operated to the N position, but since the operation of the shift lever 32 to the N position within the predetermined time ta is the second time, the special mode is entered. No migration has taken place. Since the shift lever 32 is operated to the N position at the time of t28 and it is the third operation of the shift lever 32 to the N position within the predetermined time ta, the special mode determination means 100 selects the second shift range determination means 106. At the same time, the auto park by the auto park determination means 102 is invalidated, and the shift to the special mode is carried out. At the time of t29, the vehicle power supply is partially turned off so that at least the shift range and the park range can be selected. If the transition to the special mode is not performed, the vehicle power is turned off.

FIG. 9 is a time chart after the transition to the special mode, and the same operation as the special mode in the time chart of FIG. 4 is performed. The special mode is selected before the time t31, and the special mode determining means 100 selects the second shift range determining means 106. At the time of t31, the shift lever 32 and the park switch 34 are operated, but the second shift range determining means 106 gives priority to the signal of the operation of the park switch 34 and selects the P range as the shift range.

FIG. 10 shows an example of the operation of switching from the normal mode to the special mode shown in the time chart of FIG. 8, the flow in the normal mode shown in the flowchart of FIG. 5, the flow in the special mode shown in the flowchart of FIG. 6, and the like. It is a flowchart shown in combination.

In FIG. 10, in S410 corresponding to the function of the special mode determination means 100, it is determined whether or not the power off operation is performed by the operation of the vehicle power switch 40. When the determination of S410 is denied, the shift range in the normal mode shown in S10 to S40 of FIG. 5 is set in S430 corresponding to the function of the first shift range determination means 104, and the determination from S410 is made. It is repeated. If the determination in S410 is affirmed, the shift range is set to the P range in S420 corresponding to the functions of the special mode determination means 100 and the auto park determination means 102. In S440, which corresponds to the function of the special mode determination means 100, it is determined whether or not the operation of the shift lever 32 to the N position is performed three times within a predetermined time ta. If the determination in S440 is denied, the determination in S410 is repeated. If the determination in S440 is affirmed, the shift range is set to the N position in S450, which corresponds to the function of the special mode determination means 100. Further, in S460 corresponding to the function of the special mode determination means 100, the power supply can be partially turned off, that is, the shift range and the P range can be selected, and the power supply state in which the drive power supply of the vehicle 10 is turned off is maintained. Further, in S470 corresponding to the function of the special mode determination means 100, the selection of the special mode, that is, the determination by the second shift range determination means 106 is selected. After that, that is, in S480 to S510 corresponding to the function of the second shift range determination means 106, the same flow as in 60 to S90 of FIG. 6 is executed.

According to this embodiment, the same effect as that of the first embodiment can be achieved. That is, a shift lever 32 operated to select a shift range other than the P range, a shift operation device 30 including a park switch 34 operated to select the P range, and an operation for switching the vehicle power supply. The electronic control device 90 of the vehicle 10 includes a vehicle power switch 40 to be used, an auto park determination means 102 for selecting a P range and stopping the vehicle power supply based on a power off operation by the power switch 40. The first shift range determination means 104, which selects the shift range by giving priority to the operation of the shift lever 32 over the operation of the park switch 34, and the shift lever 32 in the neutral position three times within a predetermined time ta after the operation of turning off the vehicle power supply. When the switching operation is performed, the shift range and the P range can be selected. The special mode determination means 100 for determining the transition to the special mode for maintaining the power supply state is provided, and the transition to the special mode can be performed. If it occurs, the second shift range determining means 106 selects the shift range, and if the shift to the special mode does not occur, the first shift range determining means 104 selects the shift range. As a result, even when a mode (state) that enables a part of the vehicle power supply to be turned off while maintaining the neutral range is added, if an erroneous signal is output from the shift lever 32, the vehicle It is possible to put 10 in the parking lock state.

For example, in the above-described second embodiment, the condition for shifting to the special mode is that the shift lever 32 is operated to the N position three times within a predetermined time ta, but it does not have to be three times, and the predetermined time, for example, 1 It may be twice, or four times or more.

Further, instead of operating the seat lever 32 of the first and second embodiments, the shift to the special mode may be provided with a switch or the like for operating the shift to the special mode.

Further, the vehicle power supply in the case of shifting to the special mode may be such that the drive power supply is turned off and the shift range and the P range can be operated, and for example, audio and car navigation cannot be operated.

It should be noted that the above is only one embodiment, and the present invention can be implemented in a mode in which various changes and improvements are made based on the knowledge of those skilled in the art.
