Title: Power unit for vehicle
Inventor: IMAI IWAO
IPC: G05F1/10
Filed: 1986-10-27
Abstract: PURPOSE:To activate each part without generating a fault by supplying power to an actuator from a 1st power supply and to an electronic circuit from a 2nd power supply and providing an alternator having two power generating functions so as to prevent the malfunction of the electronic circuit. CONSTITUTION:Powers are supplied from a battery 21 to the actuator 29 and from a battery 37 to the electronic circuit 36 respectively. Moreover, an electronic control unit 31 drives an inductive load 27 by a photocoupler 45. Thus, the occurrence of a low voltage at power momentary interruption, high frequency noise and the invasion of a surge are avoided. As a result, since no malfunction nor destruction is caused in the circuit 36, the reliability is improved. Since the battery 37 can be installed in a cabin, the power source wiring is much reduced. Moreover, the battery 21 is charged via the output terminal 23E of the alternate 23 and the battery 37 is charged via an output terminal 23F respectively. Thus, no hindrance is given to the operation of the actuator 29 and the circuit 36.
