摘要： In a vehicle steering apparatus, a steering actuator is controlled so that the steering angle varies in accordance with the operation of an operating member. A transmission mechanism connects an operating side rotating member that is mechanically connected to the operating member and a vehicle wheel side rotating member that is mechanically connected to the vehicle wheels so that the mutual transmission of rotation is possible. Furthermore, the rotational transmission ratio between the operating side rotating member and the vehicle wheel side rotating member can be varied.

摘要： The steering device is constructed by supporting a center portion of a rectangle-plate-shaped operation plate at one end of a supporting shaft projected from the front face of a dashboard so as to freely swing in right and left directions. A steering apparatus for a vehicle having the steering device detects the swing direction and the swing angle of the operation plate with a steering angle sensor provided at a support portion and moves a steering mechanism in the detected direction in accordance with the detected angle so as to steer the vehicle. With this structure, a load in steering can be decreased and tiredness in driving can be reduced. Furthermore, such a steering apparatus can realize a steering device which physically handicapped drivers can operate easily.

摘要： A vehicle steering apparatus in which a mechanical coupling between a steering member and steered wheels is uncoupled, includes a steering actuator for driving a steered mechanism and a control unit for drive-controlling the steering actuator. The control unit reduces steering-stiffness using a PID control portion for drive-controlling the steering actuator according to a deviation between a target steered angle and a steered-angle detected by the steered angle sensor. A gain setting portion sets gains of the PID control portion to be relatively low when a predetermined condition is satisfied.

摘要： A steered shaft of a steered mechanism is rigidly fixed to a vehicle body. Steering-stiffness is reduced by a lowpass filter for filtering a steered angle detected by a steered angle sensor. A deviation between a target steered angle and the filtered steered angle detected by the steered angle sensor is input to a PID control unit. A gain setting unit sets each of gains for PID control at a low value to thereby reduce steering-stiffness. The PID control unit outputs a target current. A drive circuit performs, e.g., PID control of the steering actuator.

摘要： A control system enables a considerable decrease in electric power consumption of backup power, leading to effective prevention of a dead battery, while data in each control unit which need be maintained even after power is turned off is properly maintained. An ECU has a first transmitter to transmit data which need be maintained to an ECU for storage when a change in position of an IGSW connected to a battery to the off position is detected, and a power supply cutoff circuit to cut off the power supply to the other ECUs after the completion of the transmission of data to the ECU for storage by the first transmitter, wherein the ECU for storage has a first storage controller to store the data transmitted from the other ECUs in RAM, and a power switching circuit to detect the change of the IGSW to the off position and switch the power of the ECU for storage to the backup power.
