Abstract
A vehicle that includes an electric power generating section, an electric motor, a charge storage section that exchanges electric power with the electric power generating section and the electric motor is provided. In the vehicle, a requested drive force setting section sets a requested drive force to move the vehicle, a central value setting section sets a central value of a state of charge in a range of state-of-charge control used to control the state of charge of the charge storage section, based on an accelerator operation, and a control section controls the state of charge of the charge storage section based on the set central value, and further controls the electric power generating section and the electric motor so that the vehicle moves by the set requested drive force.
Claims14
(canceled)
The vehicle according to claim 14, wherein the control central value setting section sets the central value based on a brake operation, in addition to the accelerator operation.
The vehicle according to claim 14, wherein the control central value setting section computes a vehicle weight based on a motive drive force that is output to move the vehicle and an acceleration of the vehicle, and sets the central value based on the accelerator operation, the computed vehicle weight, and the vehicle speed.
The vehicle according to claim 14, wherein:
- the requested drive force setting section sets the requested drive force based on the accelerator operation and a brake operation;
- and
- the control central value setting section sets the central value based on the requested drive force.
The vehicle according to claim 14, wherein:
- the requested drive force setting section sets the requested drive force based on the accelerator operation and a brake operation;
- the control section sets a target drive state of the electric motor based on the set requested drive force and also controls the electric motor so that the electric motor is driven in the set target drive state;
- and
- the control central value setting section sets the central value based on the drive state of the electric motor.
The vehicle according to claim 14, wherein the electric power generating section includes an internal combustion engine, and a generator that generates electric power by using at least a part of power from the internal combustion engine.
A method of controlling a vehicle that includes an electric power generating section that generates electric power when supplied with fuel, an electric motor that outputs motive power, and a charge storage section that exchanges electric power with the electric power generating section and the electric motor, comprising:
