Power supply circuit breaking apparatus for motor vehicle and power supply circuit breaking system for motor vehicle
First Claim
1. A power supply circuit breaking apparatus for a motor vehicle, comprising:
- a first power supply path for supplying power to a first load from a battery to be mounted on the motor vehicle;
a second power supply path for supplying power to a second load from the battery, the second load being different from the first load;
a circuit breaking control means for receiving an impact detection signal outputted when an impact such as a crash of the motor vehicle has been detected from outside, and generating and applying a circuit breaking control signal based on the impact detection signal; and
a circuit breaking means for interrupting the first power supply path forcibly and stopping the supply of power to the first load based on the circuit braking control signal.

Abstract
A circuit breaking control unit receives an impact detection signal that is outputted from outside when an impact such as a crash of a motor vehicle has been detected, and generates and applies a circuit breaking control signal based on the impact detection signal. A circuit breaking unit forcibly interrupts a power supply path and stops the supply of power to a load. Therefore, the supply of power can be stopped immediately at the time the impact has been detected. In addition, a second load is a minimum electric system that is essential to cause the motor vehicle to travel. Therefore, even if the supply of power to the load is interrupted, the motor vehicle can be caused to travel. Hence, even at the time of an accident or the like, the motor vehicle can be moved to the edge of a road or the like with ease.
