Method for Operating an Electromechanical Vehicle Brake System
Abstract:
A method is provided for operating an electromechanical vehicle brake system having an ESP module and at least two brake circuits, each brake circuit comprising high and low pressure switching valves, a low pressure storage device, and two wheel brakes. The method comprises, in advance of a possible breaking procedure and based on a trigger factor, filling the low pressure storage device with an amount of brake fluid at a first pre-pressure. Subsequently, an ESP pump is used to fill the vehicle brake system, including the low pressure storage device, with an adjustable amount of final pre-pressure. All valves are closed when the final pre-pressure is achieved. The method further comprises, during a braking procedure, opening respective inlet valves of the wheel brakes and supplying at least a part of the final pre-pressure to at least one wheel brake of the vehicle brake system.
