Abstract
A lane keeping assist apparatus has a vehicle speed responsive adjustment section which receives a target steering angle and a vehicle speed, sets a vehicle speed adjustment coefficient on the basis of the vehicle speed, multiplies an FF target steering torque by the vehicle speed adjustment coefficient, and outputs the resultant value as an adjusted FF target steering torque. The vehicle speed adjustment coefficient is set to 0 when the vehicle speed is lower than a first set vehicle speed and to 1 when the vehicle speed is higher than a second set vehicle speed. An adding section adds the adjusted FF target steering torque and an FB target steering torque together and outputs the resultant value as a final target steering torque.
