Abstract
A vehicle control apparatus according to the present invention includes a PHEV-ECU containing a measuring unit which measures the amount of torsional stress on the front drive shafts in a parking lock state and a control unit which controls the torque of the front motor. When the parking lock state is released, the torque acting as a load on the rotation of the first motor upon the release of the torsional stress on the drive shaft, is determined based on the torsional stress measured. Further, the front motor is controlled to output the determined torque.
Claims7
A vehicle control apparatus comprising:
- a first motor configured to drive wheels of one of a front side and a rear side provided on a vehicle;
- a second motor configured to drive wheels of an other one of the front and rear sides provided on the vehicle;
- a first transmission mechanism comprising a drive shaft and configured to transmit a driving force produced by the first motor to the wheels of the one of the front and rear sides;
- a second transmission mechanism configured to transmit a driving force produced by the second motor to the wheels of the other one of the front and rear sides;
- a parking lock unit configured to create a parking lock state which inhibits transfer of the driving force produced by the first motor;
- a lock control unit configured to control the parking lock unit to release the parking lock state in response to an operation which requests the release of the parking lock state;
- a measuring unit configured to measure torsional stress on the drive shaft in the parking lock state based on a degree rotation of each of the first motor and the second motor;
- a determination unit configured to determine, upon the release of the parking lock state by the lock control unit, a torque acting as a load on the rotation of the first motor upon the release of the torsional stress on the drive shaft, based on the torsion stress measured by the measuring unit;
- and
- a motor control unit configured to control the first motor to output the torque determined by the determination unit.
