摘要： A lane departure prevention apparatus is configured for improving safety of a vehicle while preventing lane departure. The lane departure prevention apparatus basically comprises a lane departure tendency determining section, a running condition determining section and a braking force control section. The lane departure tendency determining section determines a lane departure tendency of the host vehicle from a driving lane. The running condition determining section determines a running condition of the host vehicle. The braking force control section controls a braking force to selectively produce at least one of a yaw moment on the host vehicle in accordance with the lane departure tendency of the host vehicle to avoid departure of the host vehicle from the driving lane, and a deceleration on the host vehicle in accordance with the running condition of the host vehicle.

摘要： A system for assisting a lane-keep traveling of a vehicle is comprised of a camera for detecting a view ahead of the vehicle, a vehicle behavior detector including a vehicle speed sensor and a yaw rate sensor, and a controller. The controller is arranged to estimate a road shape on the basis of lane markers detected by the camera, to detect a target yaw rate necessary to return the vehicle at a center of the lane markers, and to determine that there is a possibility that the vehicle deviates from the lane when a difference between the target yaw rate and an actual yaw rate detected by the yaw rate sensor becomes greater than a threshold.

摘要： In accordance with a vehicle running condition along a lane and an actual steering angle, a control unit determine a target steering angle to follow the lane, and controls an actual steering torque with an actuator to a target steering torque to achieve the target steering angle. The control unit limits the target steering torque by setting a target torque limit determined in accordance with a sensed longitudinal acceleration of the vehicle.
