Abstract
A hybrid vehicle control apparatus includes an engine, a motor, first and second engaging elements, an input rotational speed and a controller. The first engaging element is arranged between the engine and the motor to selectively connect and disconnect the engine and the motor. The second engaging element is arranged between the motor and a drive wheel to selectively connect and disconnect the motor and the drive wheel. The input rotational speed detecting section is configured to detect an input rotational speed of the second engaging element corresponding to a rotational speed of the motor. The controller is configured to determine whether the second engaging element is seized based on the input rotational speed when a disengagement command or a slip engagement command has been issued to the second engaging element and a drive force of at least one of the engine and the motor has been changed.
