Abstract: A weight ratio of each driving wheel of the vehicle at the time of automatic driving is calculated, a front and rear distribution ratio of a driving force of the vehicle is calculated from the weight ratio, a rear wheel plan driving force is calculated from the front and rear distribution ratio and an action plan required driving force, and a temperature of a rear wheel motor is estimated. Then, when the estimated attainment temperature of the rear wheel motor is higher than the upper limit value of the temperature, the front and rear distribution ratio is changed within a range in which excessive slip does not occur at the front wheels, the rear wheel plan driving force is recalculated, and the automatic driving of the vehicle is implemented taking the rear wheel plan driving force as a target driving force.

Abstract: The control method of a vehicle is a method to control the vehicle at the time of switching from the automatic driving to the manual driving, changes driving force distribution of the vehicle to right and left driving force distribution, and gradually or stepwisely switches to the manual driving while returning the right and left driving force distribution to original driving force distribution. In addition, a steering amount at the time of the automatic driving is stored when a requirement of switching from the automatic driving to the manual driving is issued, the driving force distribution of the vehicle is changed to the right and left driving force distribution based on the steering amount at the time of the automatic driving, and the automatic driving is gradually or stepwisely switched to the manual driving while the right and left driving force distribution is returned to the original driving force distribution.

Abstract: In the vehicle control system, a driving control part includes a relative speed calculating part which detects an advancing direction of an object approaching the vehicle and calculates a relative speed between the vehicle and the object approaching the vehicle, a moving direction predicting part which, in a case where it is determined that the object is going to collide with the vehicle, predicts a movement of the vehicle after a collision, and a collision reducing vehicle turning control part which, in a case where it is determined that the vehicle is going to collide with the object around the vehicle, exerts driving control which changes the orientation of the vehicle to a direction in which the vehicle does not collide with the object around the vehicle or to a direction in which the collision to the object around the vehicle by the vehicle is alleviated.

Abstract: The disclosure provides a vehicle control system capable of mitigating the impact when an object collides with a vehicle by exerting active driving control on the vehicle, and capable of protecting an occupant. In a vehicle control system, a driving control part includes a relative speed calculating part which detects an advancing direction of an object approaching the vehicle and calculates a relative speed between the vehicle and the object approaching the vehicle, and an acceleration control part which, based on the relative speed, a position of the object, and the advancing direction of the object approaching the vehicle, in a case where it is determined that the object is going to collide with the vehicle, performs acceleration control to exert driving control which accelerates the vehicle in the advancing direction, so as to reduce the relative speed calculated by the relative speed calculating part.
