METHOD FOR ADJUSTING BRAKE PRESSURES OF A MOTOR VEHICLE BY CONTROLLING A PRESSURE CONTROL VALVE, BRAKE SYSTEM FOR CARRYING OUT THE METHOD AND MOTOR VEHICLE

摘要

The invention relates to a method for adjusting the brake pressure in the brake cylinders (5, 6) of a motor vehicle (6), wherein a control unit (17), taking into account determined dynamic state variables of the wheels to be braked (4) pressure control valves (16) each having an inlet valve (19) for ventilation and with an outlet valve (20) for venting the respective brake cylinder (5, 6) drives.The invention also relates to a brake system (1) for carrying out the method as well as a motor vehicle (6) with it. In order to allow a more accurate and faster adjustment of the brake pressure at external braking requirements (25) when reducing the air volume requirement, the invention provides for determining the timing of the exhaust valve (20) in dependence on the control of the intake valve (19), the control times (tA) of the Exhaust valve (20) depending on the timing (tE) of the intake valve (19) are determined and wherein during a braking operation, a correction factor (30) is determined, with the control times (tE) of the intake valve (19) for determining the timing (tA) of the exhaust valve (20) are weighted.
