Abstract: In case a vehicle speed control is performed in response to a failure in a steer-by-wire steering system, the vehicle is prevented from accelerating following a speed reduction caused by a braking operation of the vehicle operator. The speed limit control limits a traveling speed of the vehicle below an upper limit speed upon detecting a fault in the steering system, and is configured to set a target deceleration of the vehicle according to the limited traveling speed, perform a deceleration control to bring an actual deceleration of the vehicle to become near the target deceleration, and restrict the actual deceleration from changing to an acceleration side in the deceleration control.

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: 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.
