Abstract
A vehicle control system increases the travel distance of a vehicle by inhibiting reduction in the SOC of a battery even when the output of an engine is limited. The control system is characterized by comprising: an electric motor that drives a vehicle: an engine that drives a power generator that generates electric power to be supplied to the electric motor; a battery that is configured to be chargeable by the power generator and that is electrically connected to the electric motor; and a controller that controls the electric motor.
Claims7
A method for controlling a vehicle, the vehicle including an electric motor configured to drive the vehicle, an engine configured to drive a generator that generates electric power to be supplied to the electric motor, and a battery configured to be charged by the generator and electrically connected to the electric motor, the method comprising:
- a control step of limiting a driving force of the electric motor in a case where the vehicle is traveling in an environment in which an output of the engine is limited, wherein
- in the control step, in the case where the vehicle is traveling in the environment, limiting the driving force of the electric motor by a limit amount that is set based on a vehicle speed of the vehicle when the vehicle speed of the vehicle is equal to or higher than a predetermined value, and
- not limiting the driving force of the electric motor when the vehicle speed of the vehicle is lower than the predetermined value.

- an engine configured to drive a generator that generates electric power to be supplied to the electric motor;
- a battery configured to be charged by the generator and electrically connected to the electric motor;
- and
- a controller configured to:
- control the electric motor by limiting a driving force of the electric motor in a case where the vehicle is traveling in an environment in which an output of the engine is limited, wherein
- in the case where the vehicle is traveling in the environment, the controller is configured to limit the driving force of the electric motor by a limit amount, the limit amount of the driving force of the electric motor set based on a vehicle speed of the vehicle when the vehicle speed is equal to or higher than a predetermined value, and
- the controller is configured to not limit the driving force of the electric motor when the vehicle speed of the vehicle is lower than the predetermined value.
