Abstract: A steer-by-wire steering system for a motor vehicle may include a steering column having a support unit and a steering shaft rotatably mounted in the steering column, a steering handle disposed in a rotationally fixed manner on the steering shaft, and a feedback actuator that is configured to apply a torque to the steering shaft. The feedback actuator here may be disposed outside the support unit, as a result of which installation space is available in the region of the steering column. The feedback actuator of the steer-by-wire steering system may in some cases be disposed on a bulkhead of a motor vehicle body.

Abstract: A control system for a steering system of a vehicle, the control system comprising: a processing module configured to obtain an indication of a proximity of a road wheel of the vehicle to a limit of adhesion, and to generate a driver feedback signal in the event that the road wheel is at or beyond the limit of adhesion; and an output arranged to issue the driver feedback signal.

Abstract: A control unit (18) for an active suspension system (14) of a vehicle (10) having one or more wheels (22), the control unit (18) comprising: at least one input for receiving a signal comprising data related to the topography of terrain in a driving direction of the vehicle (10); at least one output for outputting a control signal for controlling one or more suspension system actuators (34) associated with each respective wheel (22) of said one or more wheels (22); and a processing module arranged to: analyse received data to identify a surface feature (12); determine, in dependence on a current vehicle state, a desired wheel displacement relative to a body of the vehicle for each of said one or more wheels (22) when each wheel (22) negotiates the surface feature (12); determine a control signal for said one or more suspension system actuators (34) in dependence on each respective desired wheel displacement, wherein the control signal defines future adjustments to operation of the or each suspension system act
