PROBLEM TO BE SOLVED: To provide a lane deviation suppression device capable of suppressing giving of discomfort to a driver and suppressing a vehicle from deviating from a lane.SOLUTION: A lane deviation suppression device is provided on a vehicle which mounts thereon, a steering angle change mechanism 83 for changing a steering angle and a motor 82 for operating the steering angle change mechanism 83, and the lane deviation suppression device comprises: a main control part 731 for outputting a main control signal which indicates a main control amount for causing the motor 82 to generate assist torque for changing the steering angle, after a position of a vehicle reaches to a deviation start position for starting to deviate the vehicle, for suppressing deviation of the vehicle from a lane; and a pre-control part 732 for outputting a pre-control signal which indicates a pre-control amount for causing the motor 82 to generate assist torque which is equal to or lower than friction torque which the steering angle change mechanism 83 has, until the main control part 731 outputs the main control signal in a state in which the position of the vehicle is near a lane center side relative to the deviation start position.SELECTED DRAWING: Figure 1

    【課題】運転者に違和感を与えてしまうことを抑制しつつ、車両が車線を逸脱してしまうことを抑制できる車線逸脱抑制装置を提供する。【解決手段】舵角を変化させる舵角変化機構83と、舵角変化機構83を動作させるモータ82とを搭載した車両に備えられ、車両が車線を逸脱することを抑制するために、車両を偏向させ始める偏向開始位置に車両の位置が到達した以降に、操舵角が変化するアシストトルクをモータ82に発生させるための本制御量を表す本制御信号を出力する本制御部731と、車両の位置が偏向開始位置よりも車線中央側に位置している状態で、本制御部731が本制御信号を出力するまで、舵角変化機構83が持つ摩擦トルク以下のアシストトルクをモータ82に発生させるためのプレ制御量を表すプレ制御信号を出力するプレ制御部732とを備える。【選択図】図1
