Abstract
A vehicle includes an engine, a starter motor, a torque converter, a lock-up clutch configured to perform lock-up, a traveling motor, and a controller. The controller is configured to perform processing including: switching between an engine traveling mode in which the vehicle travels using the engine and a motor traveling mode in which the vehicle travels using the traveling motor; and prohibiting, in response to a request to switch from the motor traveling mode to the engine traveling mode, the lock-up when a rotational speed of the engine is lower than a self-recovery lower limit rotational speed and higher than a starter motor drive upper limit rotational speed.
Claims4
A vehicle comprising:
- an engine;
- a starter motor configured to start the engine;
- a torque converter configured to amplify torque of a crankshaft coupled to the engine and transmit the torque to a turbine shaft;
- a lock-up clutch configured to engage the crankshaft with the turbine shaft to perform lock-up;
- a traveling motor;
- and
- a controller, wherein
- the controller comprises:
- one or more processors;
- and
- one or more memories coupled to the one or more processors,
- the one or more processors are configured to execute processing comprising:
- switching between an engine traveling mode in which the vehicle travels using the engine and a motor traveling mode in which the vehicle travels using the traveling motor;
- and
- prohibiting, in response to a request to switch from the motor traveling mode to the engine traveling mode, the lock-up when a rotational speed of the engine is lower than a self-recovery lower limit rotational speed and higher than a starter motor drive upper limit rotational speed.
