In a control of a motive power apparatus for a hybrid vehicle, the coil temperatures of first and second rotary electric machines and an air pressure index value are acquired, and upper limit values of the outputs of the machines are determined on the basis of the values acquired. If the output of one of the machines is restricted by the determined upper limit value of the output, the output of the other is increased. Alternatively, the upper limit values of the outputs of rotary electric machines are determined by applying the acquired coil temperatures to a relation between the coil temperature and the upper limit value of the output which relation is set for each air pressure index value. If the output of one of the first and the second rotary electric machines is restrained by the determined upper limit values, the output of the other is increased.
