Abstract
A stop control system for a vehicle is provided, which is capable of stably performing cranking for restarting an internal combustion engine and positively preventing the vehicle from moving by properly increasing a braking force of the vehicle, during an idle stop. In the stop control system for a vehicle according to the present invention, the engine 3 is cranked by the starter motor 6 using the power supplied from the battery 7, when restart conditions are satisfied (step 8 in FIG. 5). Further, the stop control system includes a hydraulic pump 55 driven by the power supplied from the battery 7, for increasing the braking force of the vehicle V. During a stop of the vehicle V, it is determined whether or not the braking force of the vehicle V needs to be increased (FIG. 6), and the hydraulic pump 55 is controlled according to a determination result. Further, in a case where it is determined that the braking force of the vehicle V needs to be increased, the operation of the hydraulic pump 55 is inhibited for a predetermined time period during cranking (steps 36, 37, 41 in FIG. 8).
