Beschreibung
Zusammenfassung:	A drive control apparatus for an electric vehicle includes a controller that controls an engine, a traveling motor, a transmission, and an output clutch. The controller estimates the rotation angle of the motor by a first estimation method and controls the motor on the basis of the estimated angle. The estimation method is executable when the rotation speed of the motor is a threshold or higher. When a rotation angle sensor for the motor is in an abnormal state and a specific driving state is present, the controller controls one or more of the engine, the transmission, and the output clutch differently from when the sensor is in a normal state, and thereby maintains the rotation speed at the threshold or higher. The specific driving state is a state in which the rotation speed is lower than the threshold under the control when the sensor is in the normal state.
