Claim:
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 engine; control means for controlling said braking force-increasing device according to a determination result by said braking force increasing necessity-determining means; and cranking time period-acquiring means for acquiring a time period of cranking performed by said cranking means, wherein said braking force-increasing device includes a first braking force-increasing device and a second braking force-increasing device, wherein in a case where it is determined that the braking force of the vehicle needs to be increased, said control means inhibits operations of said first braking force-increasing device and said second braking force-increasing device until the acquired time period of cranking reaches a first predetermined time period, causes said first braking force-increasing device to operate while continuing the cranking when the time period of cranking reaches the first predetermined time period, and thereafter, causes said second braking force-increasing device to operate while continuing the cranking when the time period of cranking reaches a second predetermined time period that is more than the first predetermined time period.
