ABSTRACT:
A vehicular use power distribution apparatus includes a battery mounted in a vehicle; a main control means connected directly to the battery; a first switch means connected to the battery; a power feed line for loads connected to the first switch means and supplying power to loads mounted in the vehicle; a second switch means connected to the battery; a power feed line for control means connected to the second switch means and controlling the loads; and a sub control means connected to the power feed line for control means. In a first state, the main control means sets the first switch means and the second switch means to a connection state so as to supply power from the battery to the power feed line for loads and the power feed line for control means. When there is not change in first and second mode switching signals within a first predetermined time after a change of first mode switching signal, the main control means sets the first switch means to a non-connection state to set a second state where the supply of power to the power feed line for loads is stopped. After a second predetermined time has passed in the second state, the main control means sets the second switch means to a non-connection state to set a third state where the supply of power to the power feed line for loads is stopped.
