Abstract
When a torque control value (TR) is larger than a threshold value and vehicular speed (SV) is lower than a threshold value an upper temperature limit setting unit sets the upper temperature limit of a motor generator at an upper temperature limit (TS) higher than a normally set upper temperature limit (TS). A torque limitation control controls limiting a torque of the motor generator, as based on a motor temperature (T) and the upper temperature limit set by the upper temperature limit setting unit.
