Abstract: A P-ECU controls an actuator which drives a shift control mechanism. An encoder signal acquisition unit acquires signals output from an encoder which detects a rotational angle of the actuator. A counter calculates a count value from the output signals of the encoder. An energization control unit controls energization to the actuator. A first phase-matching unit uses the Z-phase signal of the encoder to match the count value with energized phases so as to find a correspondence therebetween and a second phase-matching unit matches the count value with energized phases to find a correspondence therebetween without using the Z-phase signal of the encoder. If the first phase-matching unit detects an abnormality of the encoder, the second phase-matching unit subsequently performs phase matching.

Abstract: A P-ECU determines whether or not energization to an actuator is shut off when a shift-range switch instruction is unissued. If energization to the actuator is shut off, the P-ECU obtains a current rotational position of the actuator according to a count value obtained by an encoder. If a difference between a target rotational position and the current rotational position exceeds a predetermined amount, positional correction control is exercised.

Abstract: A control system for a hybrid vehicle that is capable of absorbing an inertial force which is generated during shifting of a stepped transmission. During shift control of the stepped transmission by a shift control device and before the shift control is completed, a during-shift drive control element controls a driving force which is output from a second drive unit such that a total driving force which is output from first and second drive units to the drive wheels equals a driver request output. Further, the during-shift drive control elements executes control so as to reduce a difference between the total driving force output to a drive wheel and the driver request output based on a change in a transmission force of the stepped transmission caused by a switch-over between a first brake and a second brake.

Abstract: A shift control system rotates an actuator to allow a wall of a detent plate and a roller of a detent spring to contact each other and then detects the position of contact so as to detect the position of the wall of the detent plate. After the wall position is determined, the actuator is driven in the direction opposite to the wall until the actuator reaches a position located before the wall position and distant therefrom by a predetermined amount, in order to cancel flexure or extension of the detent spring that is caused when the detent spring is pushed against the wall of the detent plate. Accordingly, such a situation where the shift position is moved by the recovery force of the detent spring can be avoided.
