A control system for controlling a vehicle which has an engine for driving
at least one of wheels thereof and a motor for driving at least one of
the rest of the wheels thereof. The control system includes: a motor
generator configured to be driven by the engine for generating first
alternating-current power at a first voltage; an inverter which converts
the first alternating-current power to second power at a second voltage
lower than the first voltage or to third direct-current power at a third
voltage; and a battery to be charged with the second power supplied from
the inverter. The motor is supplied with the third direct-current power
at the third voltage obtained from the first alternating-current power.
