Abstract
Using an estimated electric angle calculated by an electric angle estimation unit, a PWM control unit controls an output of a motor generator (MG) having an abnormality of a resolver. The electric angle estimation unit converts, into an estimated rotation angle speed, a rotation speed of MGestimated from rotation speeds of an engine and a normal motor generator mechanically coupled to MG. The estimated electric angle is calculated by correcting a sum of the estimated electric angle in a previous control period and an estimated electric angle change amount between the previous control period and a present control period obtained from the estimated rotation angle speed, with a calculated and estimated electric angle error. The electric angle error is estimated from a control command for an inverter and an actual current value detected by a current sensor.
