Abstract: A controller for determining whether a previously-detected vehicle malfunction still exists. If the malfunction is no longer detected in the sensor signals, a vehicle control system operates in a first operational state or normal operational state with respect to the previously-malfunctioning sensor (e.g., signals from the sensor are used to control the vehicle). If the malfunction continues to be detected, the vehicle control system operates in a second operational state or malfunction state with respect to the malfunctioning sensor in which the signals from the sensor are not used to control the vehicle.

Abstract: An apparatus for determining an amount of rotation of a rotatable component that rotates with respect to a stationary component. The apparatus includes a cable with a first end fixed to the rotatable component and a second end fixed to the stationary component. The cable, which supports a sensing element, is configured to wind or unwind when the rotatable component rotates with respect to the stationary component. The sensing element extends along a length of the cable and is configured to flex in response to the winding or unwinding of the cable. The sensing element has a resistance that changes in response to flexion of the sensing element. An evaluation circuit is connected to the sensing element and is configured to determine a value having a relation to the resistance and determine the amount of rotation based on the value.

Abstract: The present invention relates to a method for operating an electromagnetically controllable metering valve, which is disposed in an exhaust gas system of an internal combustion engine. For a metering of reducing agent in the exhaust gas system, the metering valve is actuated by a control and/or regulating device via an electromechanical drive unit with a first current profile, which includes a holding current phase having a first holding current level when said metering valve is open. Said metering valve and the drive unit are part of a metering module. When the internal combustion engine is switched off, said metering valve is actuated via said drive unit with a second current profile, which has a second holding current level that is increased with respect to the first holding current level. An independent claim relates to a control device set up to carry out the method.
