  • Publication number: 20230339445
    Abstract: 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.

  • Publication number: 20230339442
    Abstract: A method of operating a brake system for a motor vehicle, the brake system has a parking brake device and actuating the parking brake device for generating a parking braking force on a wheel of the motor vehicle is only permitted if a speed value falls below a speed threshold value. As such, the speed value is determined from a measured speed value corresponding at least temporarily to a speed of the motor vehicle. If the measured speed value falls below the speed value, the speed value is made to track the measured speed value with a speed gradient limited to a speed gradient limit value.

  • Patent number: 11789854
    Abstract: A user interface testing system, method, and device for a vehicle under test (“VUT”). A test system is communicatively coupled to the VUT. A test system records outputs of at least one human-machine-interface (“HMI”) responsive to a first set of test cases and then scores the recorded HMI outputs responsive to the first set of test cases. The test system generates a second set of test cases and scoring criteria for the second set of test cases based on the received first set of test cases and the recorded HMI outputs responsive to the first set of test cases. The test system performs the second set of test cases on the HMI and records HMI outputs responsive to the second set of test cases. The test system assigns scores for the recorded HMI outputs responsive to the second set of test cases using the generated scoring criteria.
