Abstract

A control apparatus for controlling a vehicle includes a travel controlling unit for executing a one-pedal function for controlling both a driving force and a braking force of the vehicle according to an operation amount of an accelerator pedal, and an output controlling unit capable of displaying, on a display device of the vehicle, a first indicator indicating that the one-pedal function is enabled and a second indicator indicating that a stopped state of the vehicle is being held by a braking force of the one-pedal function.

First claim

What is claimed is:

1. A control apparatus for controlling a vehicle, the apparatus comprising:
a travel controlling unit for executing a one-pedal function for controlling both a driving force and a braking force of the vehicle according to an operation amount of an accelerator pedal; and
an output controlling unit capable of displaying, on a display device of the vehicle, a first indicator indicating that the one-pedal function is enabled and a second indicator indicating that a stopped state of the vehicle is being held by a braking force of the one-pedal function, wherein
the travel controlling unit starts operation of an electric parking brake, in a case where a braking force of the one-pedal function drops while the vehicle is stopped by the braking force of the one-pedal function, and
the output controlling unit ends display of the second indicator, in a case where operation of the electric parking brake is completed.

2. The control apparatus according to claim 1 , wherein
the travel controlling unit is configured to further execute an auto brake hold function for holding the stopped state of the vehicle regardless of an operation amount of a brake pedal in a case where the vehicle has stopped in a state where the one-pedal function is disabled, and
the output controlling unit displays the second indicator on the display device at a time of the vehicle being stopped by the auto brake hold function.

3. The control apparatus according to claim 1 , wherein the travel controlling unit determines that the vehicle has stopped based on a detection result of a wheel speed sensor of the vehicle.

4. The control apparatus according to claim 1 , wherein the output controlling unit ends display of the second indicator at a point in time or slightly before the point in time at which it is estimated that a braking force and a propulsive force acting on the vehicle are balanced, while the one-pedal function is being executed and the vehicle is stopped on a downslope.

5. The control apparatus according to claim 1 , wherein the output controlling unit ends display of the second indicator in response to the accelerator pedal being operated, while the one-pedal function is being executed and while the vehicle is stopped on a slope steeper than a threshold value or the vehicle is stopped in a state where the braking force of the one-pedal function has increased by the driver further pressing a brake pedal.

6. The control apparatus according to claim 1 , wherein the output controlling unit does not display the second indicator on the display device, in a case where a seatbelt is unfastened while the one-pedal function is being executed and the vehicle is traveling, and the vehicle is stopped in this state.

7. The control apparatus according to claim 1 , further comprising:
an output controlling unit configured to notify an instruction to press a brake pedal to the driver, in a case where a seatbelt is unfastened while the one-pedal function is being executed and the vehicle is traveling, and the vehicle is stopped in this state.

8. A control apparatus for controlling a vehicle, the apparatus comprising:
a travel controlling unit for executing a one-pedal function for controlling both a driving force and a braking force of the vehicle according to an operation amount of an accelerator pedal; and
an output controlling unit capable of displaying, on a display device of the vehicle, a first indicator indicating that the one-pedal function is enabled and a second indicator indicating that a stopped state of the vehicle is being held by a braking force of the one-pedal function,
wherein the output controlling unit notifies an instruction to press the brake pedal to the driver, in a case where the braking force of the one-pedal function drops while the vehicle is stopped by the braking force of the one-pedal function.

9. A method for controlling a vehicle, the vehicle including a travel controller capable of executing a one-pedal function for controlling both a driving force and a braking force of the vehicle according to an operation amount of an accelerator pedal, the method comprising:
displaying, on a display device of the vehicle, a first indicator indicating that the one-pedal function is enabled; and
displaying, on the display device, a second indicator indicating that a stopped state of the vehicle is being held by a braking force of the one-pedal function, and
the method further comprising:
starting operation of an electric parking brake, in response to the determination that a braking force of the one-pedal function drops while the vehicle is stopped by the braking force of the one-pedal function and ending display of the second indicator, in response to the determination that operation of the electric parking brake is completed, or
notifying an instruction to press the brake pedal to the driver, in response to the determination that the braking force of the one-pedal function drops while the vehicle is stopped by the braking force of the one-pedal function.

10. A non-transitory storage medium for storing a program for causing a computer to perform the method according to claim 9 .
