Electric load controller for vehicle

Abstract

Abstract PURPOSE:To prevent the exhaustion of battery power by installing a voltage detecting means for detecting the reduction of voltage of the battery mounted on a vehicle and installing a switch means which receives the voltage reduction detection signal and cuts off the supply of electricity into an electricity feeding line at least for a part of the electric load. CONSTITUTION:A fundamental electricity feeding line 2, the first and second electricity feeding lines 3 and 4 are wired with a battery 1 mounted on a vehicle, and the fundamental electricity feeding line 2 is connected with the battery 1 through an ignition switch 5, and electricity can be supplied mainly to a starter. The first electricity feeding line 3 is connected with the battery 1 through a switch means 8, and the electric load 9 such as room lamp and a radio set is connected with the electricity feeding line 3. A voltage detecting means 6 and a keyless entry means 7 are arranged in parallel in the second electricity feeding line 4. When the voltage detecting means 6 detects that the battery voltage reduces less than a prescribed limit voltage, the relay coil 14 of the switch means 8 is allowed to conduct to open a switch 15.
