MANAGEMENT OF THE DIFFERENTIAL PRESSURE THRESHOLDS OF A VACUUM PUMP CONNECTED TO THE BRAKING SYSTEM OF A MOTOR VEHICLE

摘要

The invention concerns the management of a vacuum pump connected to the braking system of a motor vehicle, and the use of an electronic control unit connected to the vacuum pump. At least one differential pressure threshold associated with the vacuum pump, selected from a first differential pressure threshold controlling the stopping of the operation of the vacuum pump, a second differential pressure threshold controlling the starting of the vacuum pump, and a third differential pressure threshold, lower than the second threshold and signalling alerts representative of operating faults, is determined by taking into account a first set of data representative of the detection or otherwise of a repetitive braking situation and/or a second set of data representative of the altitude of the vehicle.
