Power-generating control apparatus for vehicle

Abstract

A power-generating control apparatus for a vehicle having an engine and a power-generator operated by the engine or electric motor includes a slowdown detector to detect a slowdown state of the vehicle, a main battery for the vehicle, and a sub-battery. The control apparatus includes a switch-over device which switches over at least one of the main battery and the sub-battery to the power-generator or motor, which in a slowdown state detected by the slowdown detector, switches over to couple the power-generator or the motor and the sub-battery. In engine stop, the switch over device switches to the sub-battery as a power supply of operating load. Accordingly, because the sub-battery can absorb slowdown energy, driving efficiency of the power-generator or motor at slowdown becomes excellent.
