Abstract
In a brake system of a vehicle adapted to be operated automatically, the brake system includes a forecasting mechanism for forecasting a need of automatic braking, and a pump to provide a source of a pressurized working fluid for the automatic braking is started when a need of an automatic braking is forecast. By such a need forecast starting of the pump, the brake system can automatically apply an effective braking to a vehicle wheel or wheels, with no accumulator for storing the pressurized working fluid. The pump need forecasting may depend upon an estimation of a turn behavior of the vehicle and/or a detection of an obstacle in front of the vehicle.
