Provided are: a device and a method for controlling vehicle movement, with which it is possible to suppress causing uncomfortableness to vehicle occupants and causing unstable behavior during turning by automatic travel control; and a device and a method for generating a target course. In a vehicle capable of automatically controlling lateral acceleration occurring in the vehicle, the present invention controls the acceleration occurring in the vehicle such that jerk, which is the change over time of acceleration, becomes the greatest in a region where the lateral acceleration that occurs upon entering a curve is equal to or less than half the acceleration during normal turning, and the jerk decreases as the acceleration increases.

Device and method for controlling vehicle movement, and device and method for generating target course

The present invention provides a vehicle control device that can reduce the delay in the deceleration response of a vehicle to a deceleration command. The present invention modifies the distribution ratio of brake fluid pressure between front brakes and rear brakes on the basis of lateral motion information, vehicle information, and a collision risk or a traveling scene obtained from information pertaining to the external surroundings. The brake fluid pressure is distributed to only one of the front brakes or the rear brakes.
