A vehicle starter aid system is provided for a vehicle having at least one driven axle and at least one non-driven axle. An electrically controllable brake system generates brake application signals as a function of input signals for the wheel brake actuators on the at least one driven axle. The inputs signals are received from a rotational speed sensor of the at least one non-driven axle and at least one signal-generator which generates signals which represent intended driving away of the vehicle from the stationary state and are different from the wheel rotational speed signals. An electronic brake control unit controls application of the wheel brake actuators of the at least one driven axle if the rotational speed signals of the rotational speed sensor correspond to zero wheel rotational speed and at the same time the signals of the signal-generator indicate the intended driving away of the vehicle.
