Abstract

The utility model provides a collision power-off protection device and a vehicle with the collision power-off protection device. An intelligent fuse box is connected with a battery sensor through an LIN bus. When collision power-off occurs, the intelligent fuse box receives a collision signal sent by an air bag restraint system controller after a collision happens, and sends the collision signal to the battery sensor, the battery sensor automatically cuts off a power supply source of the whole vehicle, and fuel burning caused by electric leakage is avoided. When faults are generated on the vehicle and communication is lost, the intelligent fuse box carries out operations according to a finally-obtained communication state so as to ensure safety of the vehicle.
