Abstract
A process for controlling a vehicle start-stop operation having a hybrid drive with an internal-combustion engine and an electric motor, a service brake with an ABS and an electric parking brake, includes: determining, monitoring and analyzing performance parameters of the vehicle, the internal-combustion engine, the electric motor, the service brake and the parking brake; automatically releasing the parking brake in the case of a starting prompt because of determined performance parameters; driving the vehicle by the electric motor for the start; starting the engine by the electric motor if the engine is switched off; driving the vehicle by the electric motor and the engine; activating a generator operation of the electric motor in the case of a braking prompt because of determined performance parameters; activating the service brake; and automatically locking the electric parking brake when the vehicle is stopped after a previously definable deceleration time.
