A motor control apparatus for a hybrid vehicle includes a controller having a normal control mode which detects the open-circuit voltage of a battery at driving stop of the electric motor and which sets voltage parameters according to the open-circuit voltage. In addition, the controller has an electric discharge control mode which sets a battery voltage parameter at a fixed value when the battery open-circuit voltage is higher than for normal control mode. As a result, in the control apparatus for a hybrid vehicle, over-charge and over-electric discharge of the battery is prevented. By controlled charging and electric discharging, battery life is extended. Battery administration is performed by a simplified system of hardware and software.
