According to a lane keep assist electronic control unit (LKAECU), a lane recognition section recognizes a driving lane in which the own vehicle is traveling. A target trajectory generation section, a first adder, a feedforward steering angle calculation section, a feedback steering angle calculation section, a second adder, a feedforward torque calculation section, a feedback torque calculation section, and a third adder calculate demanded torque τtgt for controlling steering of the own vehicle so that deviation of the own vehicle from the driving lane is suppressed. A road surface camber correction section detects a camber estimated angle θG which is an inclination angle of a road surface of the driving lane in which the own vehicle is traveling. The road surface camber correction section detects drift of the own vehicle by calculating a yaw rate difference Δω. The road surface camber correction section corrects the demanded torque τtgt based on the camber estimated angle θG and the yaw rate difference Δω.
