Abstract
A vehicle includes an engine, a motor generator, an electrical storage device, a keeping switch, and a controller. The controller is configured to (a) cause the vehicle to travel by using the output of at least one of the engine and the motor generator, (b) control the state of charge of the electrical storage device, (c) when the keeping mode is requested in response to the signal output from the keeping switch and when the state of charge is higher than a threshold, execute a first keeping control for keeping the state of charge at a current value, and (d) when the keeping mode is requested in response to the signal output from the keeping switch and when the state of charge is lower than the threshold, execute a second keeping control for recovering the state of charge from a current value.
Claims10
A vehicle comprising:
- an engine configured to generate an output for causing the vehicle to travel;
- a motor generator configured to generate an output for causing the vehicle to travel;
- an electrical storage device configured to exchange electric power with the motor generator;
- a keeping switch configured to output a signal that requests a keeping mode, in which a state of charge of the electrical storage device is kept, in response to user's operation;
- and
- a controller configured to:
- (a) cause the vehicle to travel by using the output of at least one of the engine and the motor generator;
- (b) control the state of charge of the electrical storage device;
- (c) when the keeping mode is requested in response to the signal output from the keeping switch and when the state of charge is higher than a threshold, execute a first keeping control for keeping the state of charge at a current value;
- and
- (d) when the keeping mode is requested in response to the signal output from the keeping switch and when the state of charge is lower than the threshold, execute a second keeping control for recovering the state of charge from a current value.
A control method for a vehicle, the vehicle including an engine, a motor generator, an electrical storage device, a keeping switch, and a controller, the engine being configured to generate an output for causing the vehicle to travel, the motor generator being configured to generate an output for causing the vehicle to travel, the electrical storage device being configured to exchange electric power with the motor generator, the keeping switch being configured to output a signal that requests a keeping mode, in which a state of charge of the electrical storage device is kept, in response to user's operation, the control method comprising:
- causing the vehicle to travel by using the output of at least one of the engine and the motor generator by the controller;
- controlling the state of charge of the electrical storage device by the controller;
- executing, by the controller, a first keeping control for keeping the state of charge at a current value when the keeping mode is requested in response to the signal output from the keeping switch and when the state of charge is higher than a threshold;
- and
- executing, by the controller, a second keeping control for recovering the state of charge from a current value when the keeping mode is requested in response to the signal output from the keeping switch and when the state of charge is lower than a threshold.
