Abstract: A fail-safety valve unit of an electronically controllable pneumatic brake system for a vehicle is disclosed. The unit includes a main port for providing a first pressure, a failsafe brake port, and a failsafe brake valve. The brake valve is controllable by a control unit. The brake valve pneumatically connects the main port and the failsafe brake port when in an open position to output a failsafe brake pressure at the failsafe brake port. In the event of a fault, an electrical failure, and/or a diagnostic event of the control unit, the brake valve is in the open position and a failsafe braking operation of the vehicle is initiated through a failsafe brake pressure at the failsafe brake port by the brake system. The main port is pneumatically connected to a parking brake function to receive an output parking brake pressure or a pressure derived therefrom, as the first pressure.

Abstract: A method includes steps for controlling a pneumatic braking system of a trailer vehicle which is connected to a tow vehicle equipped with a hydraulic or pneumatic braking system. At the start of an actuation of the foot brake valve, an electrical switch is closed or opened, and a switching signal is transmitted to an electronic control unit as a braking start signal for an incipient braking process. A brake value sensor detects a brake value representative of the drivers current deceleration request and transmits the brake value to the electronic control unit as a brake value signal. The brake value sensor is used for determining the incipient braking process, and a backup valve is only deactivated by switching a redundancy valve from an open position to a blocking position if the brake value signal detected by the brake value sensor has reached or exceeded a predefined minimum signal value.

Abstract: Embodiments relate to systems and methods for sensor self-diagnostics using multiple signal paths. In an embodiment, the sensors are magnetic field sensors, and the systems and/or methods are configured to meet or exceed relevant safety or other industry standards, such as SIL standards. For example, a monolithic integrated circuit sensor system implemented on a single semiconductor ship can include a first sensor device having a first signal path for a first sensor signal on a semiconductor chip; and a second sensor device having a second signal path for a second sensor signal on the semiconductor chip, the second signal path distinct from the first signal path, wherein a comparison of the first signal path signal and the second signal path signal provides a sensor system self-test.
