[0005] Relay circuits RY1A, RY2A like the above are complicated to control
In addition, due to the contact bounce of the relay circuit RY1A, the motor control will be performed before the relay circuit RY1A is reliably switched, which may cause false blowing of the fuse.
[0006] In addition, if the motor control is performed after the relay circuit RY1A is reliably turned on (ON) in consideration of contact chattering, the engine start may be delayed.
[0007] Furthermore, as already mentioned, since the diode elements D1 and D2 are also required, the number of parts increases.
