Publication number: 20230339445Abstract: A braking system of a vehicle, with at least one brake control system with a brake pressure regulator which, in case of a braking request, builds up a hydraulic brake pressure by which the vehicle wheel brakes can be actuated. The brake control system is attached to the vehicle body via a holder. For the detection of a holder failure, an evaluation unit is provided, which acquires a sensor signal curve from an internal sensor built into the brake control system. In the evaluation unit, a signal comparison occurs. The acquired sensor signal curve is compared to a reference signal curve. In case of a significant deviation of the acquired sensor signal curve from the reference signal curve, the evaluation unit generates a holder damage signal.Type: ApplicationFiled: April 11, 2023Publication date: October 26, 2023Applicant: AUDI AGInventors: Tobias BROK, Kilian FÖRSTER, Werner SCHNEIDER, Christopher WOLFRAM

Patent number: 11738661Abstract: A method for determining potential damage to a vehicle battery. In the method, at least one acceleration data set relating to a vertical acceleration of a motor vehicle, which includes the vehicle battery, is determined. The at least one acceleration data set is then checked for the presence of a predetermined damage criterion, which indicates the potential damage to the vehicle battery.
