In a hybrid vehicle of the invention, a hybrid electronic control unit sets a drive point of an engine and torque commands Tm 1 * and Tm 2 * of motors MG 1 and MG 2 in a range of an input limit and an output limit of a battery, in order to satisfy a preset power demand, and sends the engine drive point to an engine ECU and the torque commands Tm 1 * and Tm 2 * simultaneously with the input limit and the output limit of the battery to a motor ECU. The motor ECU verifies whether the operations of the motors MG 1 and MG 2 with the torque commands Tm 1 * and Tm 2 * are in the range of the input limit and the output limit of the battery. When the operations of the motors MG 1 and MG 2 are out of the range of the input limit and the output limit, the motor ECU resets the torque commands Tm 1 * and Tm 2 * to make the operations of the motors MG 1 and MG 2 in the range of the input limit and the output limit and controls the operations of the motors MG 1 and MG 2 with the reset torque commands Tm 1 * and Tm 2 *. This arrangement effectively prevents the battery from being overcharged with excessive electric power or from being over-discharged to supply excessive electric power even in the state of electric power imbalance due to a communication lag.
