The controller includes a steering intention detecting section that detects whether a driver has an intention to steer a vehicle, a first steering torque control section that controls, when the driver has no intention to steer the vehicle, a steering torque according to the traveling condition so that the vehicle keeps a predetermined position between lane markings of a lane, and a second steering torque control section that controls, when the driver has an intention to steer the vehicle, the steering torque according to the traveling condition so that a steering operation of the driver is readily reflected on steering of the vehicle. A lane-keep control method is also provided.

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： A vehicle motion control device is configured to determine whether the lane in which the vehicle is traveling is straight or curved. If the road is curved, a target yaw rate is set such that the yaw rate of the vehicle to the target position is averaged. If the road is straight, the target yaw rate is set such that the response delay does not exceed a target value. Therefore, wavering of the vehicle with respect to the lane is suppressed, and the vehicle is controlled to move smoothly when the road is curved and briskly when the road is straight. When the road switches between a curved road and a straight road, the target yaw rate is gradually changed between a target yaw rate calculated for a curved road and a target yaw rate calculated for a straight road.
摘要翻译：车辆运动控制装置被配置为确定车辆行驶的车道是直线还是弯曲。如果道路弯曲，则设定目标横摆率，使得车辆对目标位置的偏航率平均。如果道路是直的，则设定目标横摆率使得响应延迟不超过目标值。因此，能够抑制车辆相对于车道的摇摆，并且当道路平直时道路弯曲且轻快时，车辆被控制成平稳移动。当道路在弯曲道路和直线道路之间切换时，目标横摆率在针对弯曲道路计算的目标横摆角速度和针对直路计算的目标横摆角速度之间逐渐变化。

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.
