Motor vehicle that acquires driving power for running from high voltage power supply
First Claim
1. A motor vehicle driven by a motor run by power, comprising:
- a feeding circuit breaking and connecting device provided in a feeding circuit that provides a power supply to a motor, for breaking and connecting the feeding circuit;
a collision detecting device for detecting a collision of said motor vehicle;
a failure determination device that determines a failure of said collision detecting device; and
a high voltage system shut-off control device for controlling said feeding circuit breaking and connecting device to break the feeding circuit in response to said collision detecting device detecting a collision of said motor vehicle, and to restore the connection of the feeding circuit in response to said failure determination device determining that said collision detecting device failed.

Abstract
A motor vehicle acquires driving power for running from a high voltage power supply. The vehicle has a collision detecting device that detects a vehicle collision, a deceleration detecting device that detects a deceleration of the motor vehicle, and a high voltage system shut-off control device that provides control such that a circuit of the high voltage power supply is broken in response to a collision detection signal from the collision detecting device. The circuit of the high voltage power supply is reconnected when the deceleration detected by the deceleration detecting device does not become equal to or greater than a predetermined value within a short period of time from the receipt of the collision detection signal. Therefore, if the vehicle has collided, the power supply is shut off immediately, and if the vehicle has not really collided, the power supply is not shut off so as to surely enable the vehicle to run.
