ABSTRACT:
In traffic-related stationary phases, a drive ratio of the transmission remains engaged with the engine running on a road vehicle equipped with automatic transmission. The service brake automatically remains activated for a short time after the vehicle has come to a halt as a result of a targeted braking operation. Thereby, the driver is allowed to remove his/her foot from the brake pedal, and the vehicle can be held stationary in a reliable manner on a flat or sloping road surface. This holding braking mode of the vehicle service brake system is cancelled when the driver actuates the accelerator pedal whose position is monitored by a switch.
