Abstract
A control apparatus for a vehicle is provided. The vehicle includes an engine, a first electric motor, a rotary member, and a rotation lock mechanism. The rotary member is provided between the engine and the first electric motor. The rotation lock mechanism is configured to prevent a coupling portion of the rotary member on the engine side from rotating in at least one direction. The control apparatus includes an electronic control unit. The electronic control unit is configured to learn characteristic associated with an input torque of the rotary member by applying a torque to the rotary member by the first electric motor and measuring a twist angle of the rotary member, with the rotation lock mechanism preventing the coupling portion from rotating.

A control apparatus for a vehicle,
- the vehicle including an engine, a first electric motor, a rotary member, and a rotation lock mechanism, the rotary member being provided between the engine and the first electric motor, the rotary member having characteristic associated with an input torque, and the rotation lock mechanism being configured to prevent a coupling portion of the rotary member on an engine side from rotating in at least one direction,
- the control apparatus comprising:
- an electronic control unit configured to learn characteristic of the rotary member by applying a torque to the rotary member by the first electric motor and measuring a twist angle of the rotary member, with the rotation lock mechanism preventing the coupling portion from rotating;
- and
- the electronic control unit being configured to perform predetermined control based on the learned characteristic of the rotary member.
A control method for a vehicle,
- the vehicle includes an engine, a first electric motor, a rotary member, a rotation lock mechanism, and an electronic control unit, the rotary member being provided between the engine and the first electric motor, the rotary member having characteristic associated with an input torque, and the rotation lock mechanism being configured to prevent a coupling portion of the rotary member on an engine side from rotating in at least one direction,
- the control method comprising:
- learning, by the electronic control unit, the characteristic of the rotary member by applying a torque to the rotary member by the first electric motor and thus measuring a twist angle of the rotary member by the electronic control unit, with the rotation lock mechanism preventing the coupling portion from rotating;
- and
- performing, by the electronic control unit, predetermined control based on the learned characteristic of the rotary member.
