Abstract
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.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
