METHOD FOR FAULT DETECTION IN A VEHICLE DYNAMICS CONTROL

A method for fault detection in a vehicle dynamics control, in a system which includes a power brake and a vehicle dynamics control and is configured to couple the power brake hydraulically to the vehicle dynamics control. The method includes: generating a first control signal and providing the first control signal to the vehicle dynamics control to provide a first hydraulic pressure using the vehicle dynamics control; generating the first hydraulic pressure by means of the vehicle dynamics control, wherein a second hydraulic pressure at the hydraulic coupling is controlled using the power brake in such a way that a hydraulic volume in the system remains constant; wherein, after the process of generating the first hydraulic pressure has ended, a third hydraulic pressure of the vehicle dynamics control is determined at the hydraulic coupling to detect a fault in the vehicle dynamics control.
