Abstract: A steer-by-wire steering system for a vehicle is indicated, having a steering unit which has a steering wheel angle detection unit for detecting a steering wheel angle adjusted on a steering wheel by a driver and a rack-and-pinion unit for adjusting a steering angle on a vehicle axle, for example a vehicle front axle, wherein the steering wheel angle detection unit is configured to translate the steering wheel angle adjusted by the driver into a steering angle request and to pass the steering angle request on to the rack-and-pinion unit, which is configured to adjust an axial position of a rack in accordance with the steering angle request. The steering system further has at least one electronic system which is provided outside the steering unit and coupled to the steering unit via electronic lines in terms of signaling, wherein the at least one electronic system is an electronic fallback system and, together with the steering unit, constitutes an emergency steering functional system.

Abstract: A steer-by-wire steering system for a vehicle is disclosed, having a steering wheel, at least one sensor for capturing a steering angle of the steering wheel, a processing logic unit for determining a wheel setting angle requirement on the basis of the captured steering angle, and an actuator unit for setting a wheel setting angle at wheels of the vehicle according to the wheel setting angle requirement determined by the processing logic unit. The sensor is electrically connected directly to the vehicle electrical system and is supplied with electrical energy via the latter.

Abstract: A method is disclosure for operating a steer-by-wire vehicle steering system with a steering wheel in a shut-down state of the vehicle. According to one step of the method, after the vehicle has been shut down a procedure is carried out to monitor whether the steering wheel of the vehicle is being moved. If a movement of the steering wheel is ascertained and the movement exceeds a defined first limiting value, the movement of the steering wheel is damped by a damping unit of the steering system. If no movement of the steering wheel exceeding the first limiting value was ascertained for a defined time period, no further monitoring of a movement of the steering wheel and no further damping of the movement of the steering wheel are undertaken, so long as the vehicle is shut down.

Abstract: A steer-by-wire steering system for a vehicle is disclosed. The steering system has a steering wheel, a first sensor for capturing a steering angle of the steering wheel, a processing logic unit for determining a wheel setting angle requirement on the basis of the captured steering angle, and an actuator unit for setting a wheel setting angle at wheels of the vehicle according to the wheel setting angle requirement determined by the processing logic unit. The sensor is electrically connected to the actuator unit and is supplied with electrical energy via the actuator unit. There is at least one further sensor for capturing a steering angle of the steering wheel, which further sensor is used as a fallback solution if the first sensor fails, wherein the processing logic unit is configured to process primarily a signal from the first sensor and to process the signal from the further sensor only if the first sensor fails.

Abstract: A rotation limiting means for a steer-by-wire steering system comprises a fixedly arranged outer housing and a steering column which is received at least partially in the outer housing and can be rotated relative to the outer housing. Furthermore, at least one actuating member is provided which is arranged between the outer housing and the steering column and can be rotated to a limited extent relative to the outer housing and relative to the steering column, in order to mechanically limit a rotation of the steering column relative to the outer housing. Furthermore, a steering system and a method for limiting a rotational movement in a steering system are described.

Abstract: A sensor unit for a steering system, in particular a steer-by-wire steering system, includes a component to be monitored and having a multifunctional position sensor, which has at least one spring element and at least one piezoelectric sensor, which is associated with the spring element and is provided at a first end of the spring element. The spring element is associated with the component to be monitored via a second end opposite to the first end. A steering wheel subassembly, a rack subassembly and a steering system are furthermore described.
