vehicle control device

Abstract

The control device for a vehicle has: a shutdown judging unit (21) that judges whether the last shutdown of the brake ECU (1) that controls the electric brake system (2) of the vehicle is normal or abnormal; a crank rotation judging unit (22) , which judges whether the instruction of cranking at the start of the vehicle is based on a driver's manual operation or automatically; a diagnosis unit (23), which performs a plurality of initial diagnoses at the time of vehicle start; When the closing judging part (21) judges that the closing is abnormal, and the cranking judging part (22) judges that the cranking is based on the driver's manual operation, the diagnosing part (23) omits at least One is to control by shortening or canceling the time required for the initial diagnosis.

Description

technical field [0001] The present invention relates to a vehicle control device. Background technique [0002] Patent Document 1 discloses a technology related to idling stop. That is, when the idling stop control is performed, the engine of the vehicle is automatically stopped. And the vehicle automatically restarts in response to the driver taking his foot off the brake pedal and stepping on the accelerator pedal. When the ECU is reset like this restart, preliminary inspections such as ABSECU have been conventionally performed. However, in the technique of Patent Document 1, control is performed to omit the preliminary check at the time of the restart. [0003] That is, the idling stop is performed hundreds of thousands of times by one vehicle. If the preliminary check is performed every time when restarting from idling stop, the memory of the ABSECU will be written unnecessarily since the upper limit of the number of times of writing to the memory is fixed. In addit...

AI Technical Summary

Problems solved by technology

In addition, because the warning light is turned on when the preliminary inspection is performed, the commerciality is poor

In addition, since the operation confirmation of various actuators is performed during the preliminary inspection, if the preliminary inspection is performed every time when restarting from idle stop, it will have a bad influence on the durability of the actuator.
