Abstract

A control device configured to control a vehicle is provided. The device comprises: a traveling control unit capable of executing stop hold control in an automatic brake hold function and a one-pedal function; and an output control unit capable of displaying a first indicator indicating that the one-pedal function is enabled and a second indicator indicating that the automatic brake hold function is enabled. The traveling control unit exclusively executes the automatic brake hold function and the one-pedal function. The output control unit executes at least one of ending display of the second indicator and displaying the first indicator when the one-pedal function is enabled instead of the automatic brake hold function and/or ending display of the first indicator and displaying the second indicator when the automatic brake hold function is enabled instead of the one-pedal function.

First claim

What is claimed is:

1. A control device configured to control a vehicle, the device comprising:
a traveling control unit capable of executing stop hold control in at least two functions including an automatic brake hold function of, in a case in which the vehicle is stopped by depressing a brake pedal, holding a stop state of the vehicle without depending on an operation amount of the brake pedal and a one-pedal function of controlling both a driving force and a braking force of the vehicle in accordance with an operation amount of an accelerator pedal and holding the stop state of the vehicle after the stop without depending on the operation amount of the brake pedal; and
an output control 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 the automatic brake hold function is enabled,
wherein the traveling control unit exclusively executes the automatic brake hold function and the one-pedal function, and
the output control unit executes at least one of
ending display of the second indicator and displaying the first indicator in a case in which a first transition of transitioning from a state in which the automatic brake hold function is enabled to a state in which the one-pedal function is enabled is performed, and/or
ending display of the first indicator and displaying the second indicator in a case in which a second transition of transitioning from the state in which the one-pedal function is enabled to the state in which the automatic brake hold function is enabled is performed.

2. The device according to claim 1 , wherein the output control unit exclusively displays the first indicator and the second indicator in the same region of the display device.

3. The device according to claim 1 , wherein the output control unit can further display, on the display device, a third indicator indicating that the stop state of the vehicle is held by the braking force of the one-pedal function, and a fourth indicator indicating that the stop state of the vehicle is held by the automatic brake hold function,
the output control unit exclusively displays the third indicator and the fourth indicator in the same region of the display device, and
the third indicator and the fourth indicator are the same mark.

4. The device according to claim 1 , wherein the traveling control unit performs the first transition and does not perform the second transition and
upon receiving an instruction to execute the second transition from a driver, the output control unit notifies the driver that the automatic brake hold function cannot be enabled.

5. A method of controlling a vehicle, wherein the vehicle includes:
a traveling control unit capable of executing stop hold control in at least two functions including an automatic brake hold function of, in a case in which the vehicle is stopped by depressing a brake pedal, holding a stop state of the vehicle without depending on an operation amount of the brake pedal and a one-pedal function of controlling both a driving force and a braking force of the vehicle in accordance with an operation amount of an accelerator pedal and holding the stop state of the vehicle after the stop without depending on the operation amount of the brake pedal; and
an output control 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 the automatic brake hold function is enabled, and
the method comprises:
exclusively executing the automatic brake hold function and the one-pedal function, and
executing at least one of
ending display of the second indicator and displaying the first indicator in a case in which a first transition of transitioning from a state in which the automatic brake hold function is enabled to a state in which the one-pedal function is enabled is performed, and/or
ending display of the first indicator and displaying the second indicator in a case in which a second transition of transitioning from the state in which the one-pedal function is enabled to the state in which the automatic brake hold function is enabled is performed.

6. A non-transitory computer-readable storage medium storing a program configured to cause a computer to function as each unit of a control device of claim 1 .
