Abstract
A vehicle includes an engine, a second MG for running, a battery that supplies and receives electric power to and from the second MG, and an ECU. The ECU is configured to control the engine and the second MG and to execute intake air amount learning. When the SOC of the battery exceeds a second threshold value that is higher than a first threshold value while the vehicle is running using the second MG with the engine in a stopped state, the ECU maintains the engine in the stopped state and maintains the second MG in a driven state, and then does not execute the intake air amount learning. When the SOC of the battery takes a value between the first threshold value and the second threshold value, the ECU starts the engine, drives the second MG with constant torque, and executes the intake air amount learning.
Claims8
A hybrid vehicle, comprising:
- an engine;
- a motor for running;
- a battery that supplies and receives electric power to and from the motor;
- and
- a control device configured to control the engine and the motor and to execute intake air amount learning to learn an intake air amount of the engine, wherein
- a first threshold value and a second threshold value that is higher than the first threshold value are defined for a state of charge of the battery, and
- while the hybrid vehicle is running using the motor with the engine in a stopped state, the control device
- maintains the motor in a driven state while maintaining the engine in the stopped state and does not execute the intake air amount learning when the state of charge of the battery exceeds the second threshold value, and
- starts the engine and drives the motor with constant torque to execute the intake air amount learning when the state of charge of the battery takes a value between the first threshold value and the second threshold value.

- a motor for running;
- a battery that supplies and receives electric power to and from the motor;
- and
- a control device configured to control the engine and the motor and to execute intake air amount learning to learn an intake air amount of the engine, wherein
- a third threshold value and a fourth threshold value that is lower than the third threshold value are defined for a state of charge of the battery, and
- while the motor is being regeneratively driven with the engine in a stopped state, the control device
- does not execute the intake air amount learning and maintains the motor in a regenerative state when the state of charge of the battery falls below the fourth threshold value, and
- starts the engine and regeneratively drives the motor with constant torque to execute the intake air amount learning when the state of charge of the battery takes a value between the third threshold value and the fourth threshold value.
