Abstract

A vehicle includes a power storage unit, a regenerative generator, and an electronic control unit. The regenerative generator is connected to the power storage unit and is configured to perform regenerative power generation. The electronic control unit is configured to perform regeneration amount enlargement control in which positions of stopping and deceleration of the vehicle by input of driver'"'"'s operations are predicted or set based on route information, regenerative power generation by the regenerative generator is controlled, and a regeneration power amount charged into the power storage unit is enlarged. The electronic control unit is configured to restrict the regeneration amount enlargement control when executing a predetermined vehicle speed adjustment mode by comparison with when the predetermined vehicle speed adjustment mode is not selected, the vehicle running with automatic adjustment of vehicle speed in the predetermined vehicle speed adjustment mode selected by intentional input from the driver.

Claims

the electronic control unit is configured to perform the mode switching control based on the travel plan while restricting the regeneration amount enlargement control in running in the predetermined vehicle speed adjustment mode when the predetermined vehicle speed adjustment mode is selected.

5. The vehicle according to claim 1, wherein

the electronic control unit is configured to perform control of changing a control target value of a residual charge amount in the power storage unit based on route information;

and

the electronic control unit is configured to perform the control of changing the control target value of the residual charge amount while restricting the regeneration amount enlargement control in running in the predetermined vehicle speed adjustment mode when the predetermined vehicle speed adjustment mode is selected.

6. The vehicle equipped with a regenerative generator according to claim 1, further comprising:

a display unit configured to display a first predetermined display representing execution of the regeneration amount enlargement control when the regeneration amount enlargement control is executed.

7. The vehicle according to claim 6, wherein

the display unit is configured to be controlled by the electronic control unit such that the first predetermined display is turned off during execution of the predetermined vehicle speed adjustment mode.
