METHOD OF AVOIDING THE HYDRAULIC FALLBACK LEVEL IN A BRAKE SYSTEM OF A MOTOR VEHICLE

A hydraulic brake system of a motor vehicle includes a linear actuator as a driver-independent pressure provision device and a hydraulic valve arrangement between the linear actuator and wheel brakes. In the case of a reduced availability of the linear actuator, a holding mode is carried out, in whi...

More Information
Summary:A hydraulic brake system of a motor vehicle includes a linear actuator as a driver-independent pressure provision device and a hydraulic valve arrangement between the linear actuator and wheel brakes. In the case of a reduced availability of the linear actuator, a holding mode is carried out, in which the hydraulic pressure in the wheel brakes is shut in with the valve arrangement and a power output of the linear actuator is reduced, the system pressure gradient in the holding mode is measured, and a transition from the holding mode into an alternative mode is carried out based on the system pressure gradient.
