Description

  The present invention relates to a vehicle control device that switches control specifications based on connection of a predetermined device.

  Conventionally, a vehicle control device that has a function of automatically switching to a control specification according to connection of an external device and detects the presence or absence of a device specific to a vehicle type to select a vehicle type has been considered. For example, an AT vehicle and an MT vehicle In order to switch the control specification of the vehicle, it is detected whether an AT controller that controls the AT is connected. When the connection of the AT controller is detected, the control specification of the AT vehicle is detected. When the connection of the AT controller is not detected, the control of the MT vehicle is controlled. The specification is automatically switched (for example, see Patent Document 1).

Japanese Patent Laid-Open No. 8-61137 (see paragraphs 0015 to 0019 and FIG. 1)

  However, since the device described in the above-mentioned patent document does not have a function of detecting whether or not the AT controller is normally connected, for example, when the AT controller is not connected to a normal state when it should be connected, There is a problem that, although it should be switched to the control specification of the AT vehicle, it is switched to the control specification of the MT vehicle because the connection of the AT controller cannot be detected.

  The present invention has been made in view of the above problems, and in the case where the control specifications are switched based on the connection of a predetermined device, the control specification can be switched normally by preventing the predetermined device from being disconnected. Objective.

In order to achieve the above-described object, a vehicle control device of the present invention is a vehicle control device that switches control specifications based on connection of a predetermined device, and includes a body ECU and the left and right devices that are the predetermined device. Presence / absence of connection with the headlamp , and presence / absence of connection between the auto leveling ECU and the body ECU , which is a related device that is connected to the body ECU if the left and right headlamps are LED lamps the determining means and said determining means for determining, said there connections auto leveling ECU, and the left, when it is determined that there is no in both or either one of the right headlamp connected, the left and right headlamp and output means for outputting a signal for warning the abnormal connection, the presence or absence of connection of the automatic leveling ECU by the determining means Serial control specification screened whether the control specifications of a vehicle equipped with the LED lamp, the there connected the auto leveling ECU, and the left, when there connections right headlamp, sorted by the determining means LED It is switched to the control specification of the vehicle on which the lamp is mounted (claim 1).

  The invention according to claim 1 is based on the idea that since the related device is associated with a predetermined device in advance, if either one of the related device and the predetermined device is connected, the other is also connected. doing.

Therefore, according to the first aspect of the present invention, when it is determined by the determining means that the auto leveling ECU that is a related device is connected and at least one of the left and right headlamps that is a predetermined device is not connected, A predetermined signal is output from the output means, and based on this predetermined signal, for example, warning notification is made, so that the left and right headlamps can be prevented from being disconnected, as in the conventional case. Even when the control specifications are switched according to whether the left and right headlamps are connected or not, switching to the wrong control specifications can be reliably prevented.

Further, when it is determined by the determination means that the auto leveling ECU that is the related device is connected, the vehicle is a vehicle equipped with an LED lamp , and when it is determined that the auto leveling ECU that is the related device is not connected, the vehicle Can be recognized as a vehicle that does not have LED lamps installed, so it is possible to select specifications depending on whether or not the auto-leveling ECU , which is a related device , is connected. Compared to the case where the specification is selected by detecting this, the selection function can be simplified and the cost can be reduced.

It is a block block diagram of one Embodiment of the control apparatus for vehicles which concerns on this invention. FIG. 2 is a partial functional block diagram of FIG. 1.

  An embodiment of the present invention will be described with reference to FIGS. 1 and 2.

  As shown in FIG. 1, the vehicle control apparatus according to the present embodiment is connected to the body ECU 1, the left and right LED headlamps 2 </ b> L and 2 </ b> R that are controlled by being connected to the body ECU 1, and connected to the body ECU 1 by LIN communication. The meter unit 3 is controlled and displays various warning displays in addition to the speed display, the engine speed display, the remaining fuel amount display, and the like, and is connected to the body ECU 1 via the meter unit 3 so as to be able to perform CAN communication. And an automatic leveling ECU 4 that controls the irradiation angles of 2L and 2R. Here, both the LED headlamps 2L and 2R correspond to predetermined devices in the present invention, the auto leveling ECU 4 corresponds to a related device in the present invention, and the auto leveling ECU 4 and both the LED headlamps 2L and 2R are associated in advance. Therefore, when the auto leveling ECU 4 is connected, both the LED headlamps 2L and 2R are also connected. On the other hand, when the headlamp is a halogen headlamp, there is no relevance to which the auto leveling ECU 4 should be connected.

  The body ECU 1 is configured as shown in FIG. 2, for example, and includes a CPU 11 that controls each part, a ROM 12 that stores a control program and predetermined data, a RAM 13 that temporarily stores data necessary for the processing of the CPU 11, A headlamp identification unit 14 for identifying both LED headlamps 2L and 2R, and an input / output unit for inputting information from the auto leveling ECU 4 via the meter unit 3 and outputting various display signals to the meter unit 3 15 and is constituted by a microcomputer.

  By the way, when both the LED headlamps 2L and 2R are normally connected, a pulse signal with a predetermined duty is input from both the LED headlamps 2L and 2R to the headlamp identification unit 14, while the connector is not properly fitted. When not connected, the signals from both LED headlamps 2L, 2R to the headlamp identification unit 14 are fixed to one of high level or low level, and the headlamp identification unit 14 is connected to both LED headlamps 2L, 2R. It is possible to identify whether or not the LED headlamps 2L and 2R are normally connected based on the signal.

  And CPU11 judges that both LED headlamps 2L and 2R were connected based on the identification result of both LED headlamps 2L and 2R by the headlamp identification part 14. FIG. Further, the CPU 11 receives the communication information from the auto-leveling ECU 4 that has passed through the meter unit 3 via the input / output unit, so that the auto-leveling ECU 4 associated with both the LED headlamps 2L and 2R is normally connected. Judge that Such a determination function of the CPU 11 corresponds to the determination means in the present invention.

  At this time, when the CPU 11 determines that the auto-leveling ECU 4 is connected, if the CPU 11 determines that both of the LED headlamps 2L and 2R are not connected, or if either of the LED headlamps 2L and 2R is not connected, an input error is detected. A predetermined warning display control signal is output to the meter unit 3 via the output unit 15, and the meter unit 3 displays a warning of abnormal connection between the LED headlamps 2L and 2R. Such an output function of the warning display control signal by the CPU 11 corresponds to the output means in the present invention.

  When the CPU 11 determines that the auto-leveling ECU 4 is connected and the LED headlamps 2L and 2R are not connected, a predetermined warning display control signal is output from the CPU 11 to the meter unit 3, and this warning display control signal Based on the above, a warning notification is made by the meter unit 3.

  Therefore, according to the above-described embodiment, it is possible to prevent the LED headlamps 2L and 2R including the connection failure from being disconnected by warning notification. Even when the vehicle control specifications are switched according to the presence or absence of connection, switching to an incorrect control specification can be reliably prevented.

  When the CPU 11 determines that the auto leveling ECU 4 is connected, the vehicle is a vehicle equipped with the LED headlamps 2L and 2R. When the CPU 11 determines that the auto leveling ECU 4 is not connected, the vehicle is the LED headlamp 2L. , 2R can be recognized as a non-equipped vehicle, and therefore it is possible to select specifications depending on whether or not the auto leveling ECU 4 is connected. If there are a plurality of types of LED headlamps 2L, 2R, each of the devices can be selected. Compared with the case of detecting the connection and selecting the specifications, the selection function can be simplified, and the cost of the body ECU 11 can be reduced by reducing the number of product numbers.

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

  For example, in the above-described embodiment, the case where the predetermined device is the LED headlamps 2L and 2R and the related device associated therewith is the auto leveling ECU 1, the predetermined device and the related device associated therewith are described. It is not limited to.
