摘要： A steering/turning controller: inputs a target turning angle command created based on travel environment information; determines whether the target turning angle command is a corrective turning region, in which an angle is equal to or less than an angle threshold value and an angular velocity is equal to or greater than an angular velocity threshold value, or a non-corrective turning region other than the corrective turning region; when generating a steering command angle and a turning command angle based on the target turning angle command, sets a distribution of the steering command angle to “zero” and generates only the turning command angle in the case of the corrective turning region; and generates the steering command angle and the turning command angle in the case of the non-corrective turning region.

摘要： When an own vehicle changes lanes to another lane different from the traveling lane by override, a traveling control device for a vehicle generates a first travelable area in the traveling lane based on the predicted traveling trajectory in accordance with the override of the own vehicle and generates a second travelable area along the other lane. The traveling control device for the vehicle generates a third travelable area by connecting the first travelable area and the second travelable area, generates an own vehicle traveling trajectory within the third travelable area and controls a motion of the own vehicle so that the own vehicle travels along the own vehicle traveling trajectory.

摘要： A lane keeping assist device assists a steer-by-wire vehicle to stay in a traveling lane. The lane keeping assist device controls the turning angle of the turning wheel using a first turning angle calculated to keep the vehicle in the traveling lane and using a second turning angle corresponding to the steering amount of the steering wheel. The lane keeping assist device detects a vehicle speed of the vehicle. The lane keeping assist device calculates a first reaction force command value to the steering wheel corresponding to the first turning angle and a second reaction force command value to the steering wheel corresponding to the second turning angle. The lane keeping assist device controls a steering reaction force to be imparted to the steering wheel to correspond only to the second reaction force command value when the vehicle speed is higher than a predetermined threshold value.

摘要： An in-lane drive assist device controls a turning amount of a turning unit that is mechanically detached from a steering unit-based on a steering amount of a steering unit when a lane deviation is determined to be absent. The in-lane drive assist device controls the turning amount based on a drive assist turning amount for generating a yaw moment to return a vehicle into a lane while the steering reaction force applied to the steering unit is controlled based on a target steering reaction force corresponding to a steering reaction force characteristic that is set so that a self-aligning torque increases as the steering reaction force increases when a lane deviation is determined to be present, and the steering reaction force characteristic is offset in a direction in which an absolute value of the steering reaction force increases as a lateral position of the vehicle approaches a white line.

摘要： The travel control device, when determining that the traffic congestion is occurred in the other lane, detects, behind another vehicle in the other lane, an approach space; determines whether the approach space meets a predetermined condition; when determining that the approach space meets the predetermined condition, sets the target posture of the own vehicle at the target position behind the other vehicle in the other lane based on the shape of the approach space; and generates a target traveling trajectory from a current position of the own vehicle to the target position. The travel control device controls the motion of the own vehicle so that the own vehicle tracks the target traveling trajectory.

摘要： A steering control device increases a steering reaction force of a steering reaction force actuator in a direction in which a lateral position of a host vehicle moves away from a travel path partition line when a turning amount of a turning actuator increases in the direction in which the lateral position of the host vehicle moves away from the travel path partition line. A steering reaction force control amount is computed for a reaction force suppression processing to reduce the steering reaction force control amount when the steering reaction force control amount has been at a threshold value or higher for a length of time. The reaction force suppression processing is carried out to control the steering reaction force actuator in lieu of the steering reaction force control amount. Meanwhile, the turning amount is maintained at a value occurring when the reaction force suppression processing began.
