PURPOSE:To maintain stabilized control of an electric automobile constantly by dividing a controller into blocks in accordance with functions and setting the energizing order of the blocks so that each block can stably operate at the time of starting energization, and then, controlling the energization of the blocks in the reverse order at the time of stopping the energization. CONSTITUTION:A delay circuit 1 is connected to a battery 3 through a power unit 2 for control and, at the same time, through an turning-on/off signal line 4 and key switch 5. The circuit 1 is set to successively energize a first block 6, second block 7, and third block 8 so that the blocks can stably operate when the switch 5 is turned on and successively actuates the blocks 6, 7, and 8 in this order. At the time of stopping power supply, the circuit 1 successively controls the energization of the blocks 6, 7, and 8 reversely to the set order. Therefore, the occurrence of a no-control state is eliminated and electric shocks are relieved. In addition, no strong impact nor stress is given to each parts. |
