To provide a vehicle of high degree of freedom in layout of an energy supply means such as a battery supplying energy source actuating a motor.
Drive torque of a drive motor 2 is increased during a period from a time t=0 when it is determined that collision of rear following vehicle 300 can not be avoided to a time t=t1 when the rear following vehicle 300 collides, and speed is increased from Vs0 to Vs1. Regenerative braking of the drive motor 2 and a hydraulic brake 5 are operated during a period from the time t=t1 to a time t=t2 when a vehicle 100 stops to stop the vehicle 100. Relative speed ΔVr1=Vs1-Vr1=Vs1-Vr0 at a time of collision of the rear following vehicle 300 is lower than a relative speed Vs0-Vr0 at a time of collision of the rear following vehicle 300 without acceleration of the vehicle 100. Consequently, impact at the time of collision of the rear following vehicle 300 can be mitigated.
