A wheel suspension for an at least slightly actively steerable has a wheel carrier for receiving a wheel, a toe link, and at least one further link for connecting the wheel carrier to the vehicle body, and an actuator arrangement having at least one actuator for actively steering the wheel in a first active steering direction and in a second active steering direction. The wheel carrier is formed in at least two parts and has a first wheel carrier part and a second wheel carrier part. The first wheel carrier part is designed to receive the wheel and the second wheel carrier part can be attached via at least one of the further links to the vehicle body, in a non-actively steerable manner. The first wheel carrier part and the second wheel carrier part in a functional state of use of the wheel suspension in a vehicle are movable relative to one another by the actuator arrangement, such that an active, at least slight steering movement of the wheel can be effected.

A suspension operation system includes: a suspension that includes a plurality of links supporting a wheel, at least one or more of the links having an actuator increasing or decreasing its length in an axial direction; a control device that supplies a drive signal to the actuator to control operation of the suspension; and a suspension operation terminal that operates the suspension. The suspension operation terminal includes: a detector that detects operation input information to the suspension operation terminal; and a communicator that transmits information about a target posture of the wheel, the information being based on the operation input information, to the control device as an operation command. The control device includes: a first calculator that calculates the length of the actuator on the basis of the operation command; and a drive circuit that produces the drive signal on the basis of information from the first calculator.

Vehicle suspension systems are described herein. An example apparatus includes a cam pivotably coupled to a rear axle. The example apparatus also includes a first tie rod having a first end pivotably coupled to the cam and a second end pivotably coupled to a steering knuckle. The example apparatus also includes a second tie rod having a first end pivotably coupled to the cam outboard relative to the first end of the first tie rod and a second end coupled to a steering actuator.

Vehicle suspension systems are described herein. An example wheel steering apparatus includes a steering actuator to couple to a rear axle, a tie rod, and a transfer link to couple the steering actuator and the tie rod. The steering actuator is positioned on a first side of a first longitudinal axis of the rear axle and the tie rod positioned on a second side of the first longitudinal axis of the rear axle opposite the first side.

Electric power assisted steering (EPAS) systems for solid axle front suspension vehicles are described. An example EPAS system includes an idler arm having a first end and a second end. The first end of the idler arm is coupled to a frame of the vehicle. The example EPAS system further includes an EPAS rack assembly having an input shaft, a rack, an electric motor, and an output link. The rack is coupled to the input shaft and is movable in response to movement of the input shaft. The electric motor is coupled to the rack. The electric motor provides powered assistance to movement of the rack. The output link has a first end and a second end. The first end of the output link is coupled to the rack. The second end of the output link is coupled to the second end of the idler arm.

A linear actuator for a steer-by-wire system including a component, in particular an axle or a shaft, that can be moved along a linear trajectory, and including a measuring device for determining a position of the component. The measuring device has a coil for inductively determining the position of the component, and the coil is arranged coaxially relative to the linear trajectory of the component.

A toe angle control system for a vehicle, includes: an actuator having an output part configured to receive a driving force of an electric motor via a gear transmission mechanism and to be displaced by the driving force such that a displacement of the output part varies a toe angle of a wheel; and a controller controlling the electric motor, wherein the controller is configured to calculate an operation quantity of the electric motor, and, when the controller determines that a current displacement direction of the output part and a displacement direction of the output part corresponding to the operation quantity are opposite to each other, the controller corrects the operation quantity to reduce the operation quantity.

The present invention relates to a rotary sensor assembly and a rear wheel steering system including the same. According to one embodiment of the present invention, a rotary sensor assembly includes: a rotary sensor subassembly configured to sense a stroke of a driving shaft configured to receive rotating power to move linearly; a sensing guide configured to be moved by receiving a moving force when the driving shaft moves such that the rotary sensor subassembly senses movement of the driving shaft; and fasteners which couple the sensing guide to the driving shaft, wherein the rotary sensor subassembly senses movement of the sensing guide to sense the stroke of the driving shaft when the driving shaft moves.
