  • Patent number: 10065639
    Abstract: 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.
