摘要： A vehicle steering apparatus includes a vehicle steering system and a supplemental steering force applying device. The supplemental steering force applying device is configured and arranged to apply a supplemental steering force to the vehicle steering system to reduce a steering load on the operator. The supplemental steering force applying device includes a steering torque detecting section, a rectilinear driving condition detecting section, a pulling suppression control section. The rectilinear driving condition detecting section is configured and arranged to detect a rectilinear driving condition of the vehicle. The pulling suppression control section is configured and arranged to adjust the supplemental steering force in a direction canceling a pulling force imparted on the vehicle during the rectilinear driving condition by using a pulling suppression force calculated based on historical data of the steering torque detected during the rectilinear driving condition.

摘要： An electric power steering system for an automotive vehicle, including a steering torque detecting device which detects a steering torque of a steering shaft. An electric motor is provided to generate an assist torque for assisting a driver's steering effort required for steering the vehicle and a counter-assist torque for increasing the driver's steering effort. The assist torque and the counter-assist torque are applied to a steering mechanism. Additionally, a controller is provided to output a drive command to the electric motor in accordance with the detected steering torque. The drive command is for causing the electric motor to generate the counter-assist torque when the detected steering torque is a transitional torque.

摘要： In a multiplex power steering device for a wheeled vehicle, there is provided a control unit which includes a feedback computing part. The feedback computing part comprises an operating force estimating section that, by analyzing an output from a controlled system of actuators of a steering mechanism, estimates an output of the actuators, a disturbance estimating section that, by comparing a control signal actually fed to the actuators and the estimated output of the actuators, estimates a disturbance applied to the controlled system from the exterior, and a disturbance compensating section that adjusts the control signal in a manner to remove the estimated disturbance therefrom. The control unit calculates the control signal on the assumption that the actuators constitute a single actuator.

摘要： In order to enhance the accuracy of estimation of sideslip angle β, a sideslip angle estimation apparatus calculates a first sideslip angle β2 between the direction of centrifugal force acting on the vehicle body during cornering and the lateral direction of the vehicle body based on accelerations exerted on the vehicle body and acting in two different directions. A sideslip angle between the longitudinal direction of the vehicle body and the direction of travel of the vehicle is calculated based on the calculated first sideslip angle β2.
