Abstract
A brake control device includes a processor that controls a brake device of a vehicle. The processor receives a first braking request indicating first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle. The processor receives a second braking request indicating second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle. The processor starts override control when the processor receives the second braking request while the processor controls the brake device in accordance with the first braking request.
Claims10
A brake control device comprising one or more processors configured to control a brake device of a vehicle, wherein:
- the one or more processors are configured to
- receive a first braking request indicating a first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle,
- receive a second braking request indicating a second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle, and
- start override control, when the one or more processors receive the second braking request while the one or more processors control the brake device in accordance with the first braking request;
- and
- the override control includes:
- determining a larger one of (i) the first braking force at present and (ii) a sum of the second braking force at present and the first braking force at a time when the override control is started, as an override braking force, and
- setting the determined override braking force, as a first requested braking force for the brake device.
A non-transitory computer readable storage medium storing instructions that are executable by one or more processors that control a brake device of a vehicle, and that cause the one or more processors to perform functions comprising:
- receiving a first braking request indicating a first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle;
- receiving a second braking request indicating a second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle;
- and
- starting override control, when the second braking request is received while the brake device is controlled in accordance with the first braking request,
- wherein the override control includes:
- determining a larger one of (i) the first braking force at present and (ii) a sum of the second braking force at present and the first braking force at a time when the override control is started, as an override braking force, and
- setting the determined override braking force, as a requested braking force for the brake device.
