STOP CONTROL SYSTEM FOR VEHICLE

摘要

A stop control system for a vehicle, which is capable of positively preventing movement of a vehicle by positively increasing a braking force of the vehicle during an idle stop. In the stop control system for a vehicle of the present invention, the engine 3 is cranked by a starter motor 6 using power supplied from the battery 7 when restart conditions are satisfied during an idle stop (step 8 in FIG. 5). Further, the stop control system includes a hydraulic pump 55 driven by power supplied from the battery 7, for increasing the braking force of the vehicle V. During a stop of the vehicle V, when it is determined that the braking force of the vehicle V needs to be increased (F_BFREQ=1), the hydraulic pump 55 is activated. Further, if the restart conditions are satisfied during operation of the hydraulic pump 55, the cranking is inhibited to continue the operation of the hydraulic pump 55 (steps 6 to 9 in FIG. 5).

主权项

1. A stop control system for a vehicle, for stopping an internal combustion engine installed on the vehicle having a brake system, when predetermined stop conditions are satisfied, restarting the engine when predetermined restart conditions are satisfied, and controlling a braking force of the vehicle such that the braking force is increased in order to supplement the braking force of the brake system during a stop of the vehicle, comprising:
cranking means for cranking the engine using power supplied from a predetermined power source when the restart conditions are satisfied; a braking force-increasing device that is driven by power supplied from the power source, for increasing the braking force of the vehicle; braking force increasing necessity-determining means for determining whether or not the braking force of the vehicle needs to be increased by said braking force-increasing device during a stop of the vehicle; and control means for causing said braking force-increasing device to operate, when it is determined that the braking force of the vehicle needs to be increased, wherein said control means inhibits the cranking when the restart conditions are satisfied during operation of said braking force-increasing device.
