Abstract
A method and system for management of a vacuum pump connected to a braking system of a motor vehicle, and 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 stopping of operation of the vacuum pump, a second differential pressure threshold controlling 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 altitude of the vehicle.
