  • Patent number: 11273839
    Abstract: A vehicle control device for a vehicle, the vehicle including a rotation lock mechanism preventing rotation of a coupling portion on the engine side of the rotating member in at least one direction, and an engine rotation speed sensor detecting a rotation speed of the engine, includes: a characteristic detecting portion detecting at least a torsional rigidity as the rotational characteristic by applying a torque to the rotating member from the electric motor to measure a twist angle of the rotating member while the rotation of the coupling portion is prevented by the rotation lock mechanism; and an engine rotation filtering portion calculating an actual resonance frequency based on the torsional rigidity detected by the characteristic detecting portion and filtering an engine rotation speed signal supplied from the engine rotation speed sensor to attenuate a vibration component of the actual resonance frequency in the engine rotation speed signal.
    Type: Grant
