CPC classification number: B62D5/0481
Abstract: Provided is a steering system for a vehicle that can accurately determine a degradation level of a steering actuator according to a traveling state of the vehicle. The steering system for the vehicle includes; a steering mechanism configured to steer wheels; a steering actuator configured to apply a driving force to the steering mechanism; and a controller configured to control the steering actuator. The steering mechanism includes a rack shaft that is movable in a vehicle width direction from a prescribed reference position. The controller is configured to calculate an evaluation value according to a use state of the steering actuator and to determine a degradation level of the steering actuator by comparing the evaluation value with at least one threshold that is set based on a moving amount of the rack shaft from the reference position and a vehicle speed.

Abstract: Provided is a steer-by-wire steering system for a vehicle that can reduce or eliminate the impact noise generated by the rack at the rack end. A control unit of the steering system is configured to determine a target steered angle (αt) according to the steering angle and drive the steering actuator so as to cause the steered angle to coincide with the target steered angle, and to determine a target reaction force (Tt) according to a steered state of the wheels and drive the reaction force actuator so as to cause the reaction force to coincide with the target reaction force. The control unit is further configured to set a maximum limit (αmC) on the target steered angle, the maximum limit being a value smaller than a physical maximum steered angle (αmP) of the wheels imposed by the steering mechanism.

Abstract: Provided is a steer-by-wire steering system for a vehicle that can prevent the vehicle from suddenly accelerating in a direction which the drive did not anticipate even when the steering angle of the steering member was changed while the vehicle was parked. When the steered angle deviates from the prescribed relationship to the steering angle (ST2: Yes), immediately or upon satisfaction of a trigger condition, the control unit drives the steering actuator to bring the steered angle to come closer to the prescribed relationship to the steering angle (ST16, ST17, ST20, ST21), and sets an upper limit to a speed or an acceleration of the vehicle (ST7).

Abstract: In a steer-by-wire steering system for a vehicle, a control unit (16) controls an operation of a steering actuator to cause the steered angle of wheels to be in a prescribed relationship to a steering angle, and an operation of the reaction force actuator (15) including a pair of reaction force motors (14) to cause the reaction force to be a value (Tt) corresponding to a steered state of the wheels, wherein the control unit is provided with a failure detection unit (36) configured to detect failures of the reaction force motors, and upon detecting a failure of one of the reaction force motors, progressively reduce an output (Tta) of the other reaction motor to a prescribed limit value (TL).

Abstract: To prevent a driver from feeling uncomfortable when the driver touches a steering member in a state where a driving source is stopped, a vehicle steering system (1) is provided in a vehicle (2) that travels by a driving force generated by a driving source (51). The vehicle steering system (1) includes; a steering member (10) configured to accept a steering operation; and a reaction force actuator (13) configured to apply a reaction force to the steering member (10) in response to the steering operation. In a state where the driving source (51) is stopped, the reaction force actuator (13) is configured to apply the reaction force to the steering member (10) based on a stopped time position that is a position of the steering member (10) at a time when the driving source (51) is stopped.

Abstract: In a plain bearing for a steering spindle of a steering column for a motor vehicle having an inner ring for receiving and slidingly mounting the steering spindle, the inner ring is surrounded by an outer ring, and elastic intermediate pieces are arranged between the inner ring and the outer ring . A respective elastic intermediate piece holds the inner ring at the location of the intermediate piece at a spacing from the outer ring in relation to the radial direction in the unloaded state of the plain bearing and can be compressed in the case of a force which acts on the inner ring and is directed outwards in the radial direction, the inner ring bearing against the outer ring if a limiting value of the radial force is exceeded.

Abstract: An adjustable steering column for a motor vehicle has at least two components and at least one locking device. The components can be adjusted in the position thereof relative to each other along an adjustment path in an open position of the locking device and are locked in the position thereof relative to each other in a closed position of the locking device. A stop element is arranged at least a first of the components such that the stop element limits the adjustment path and can be detached from the first of the components when a force value is exceeded. The adjustable steering column has a tool which can be inserted between the stop element and the first of the components in order to detach the stop element.
