Abstract: A vehicle control device includes a vehicle position calculating unit, an obstacle determining unit, a collision possibility determining unit, an avoidance means selecting unit, an avoidance route calculating unit, and a steering control value calculating unit that calculates a steering control value and that outputs the steering control value to a steering actuator control unit. The avoidance route calculating unit calculates a target point for avoiding the obstacle, divides an avoidance section connecting the position of the vehicle to the target point into a plurality of partial sections, calculates a partial avoidance route in each of the partial sections, and calculates the avoidance route made up of the plurality of partial avoidance routes.

Abstract: A vehicle motion control device according to the present invention obtains a translation force for causing the position of a vehicle to trace a target travel path, on the basis of a lateral displacement amount which is an amount of displacement of the vehicle in a lateral direction with respect to a target movement point, obtain a rotational force for correcting an orientation of the vehicle with respect to the target travel path, on the basis of an orientation displacement amount which is an amount of displacement of the vehicle in a yaw direction with respect to the target movement point, weight the translation force and the rotational force on the basis of specifications relating to traveling of the vehicle, and output a control command for achieving a target lateral force obtained by adding up the weighted translation force and the weighted rotational force.
