Braking force control device

A method executed by a computer of a manager mounted on a vehicle, the method comprising:

• calculating a braking request when a driver performs an accelerator pedal operation;
• receiving a braking force that is generable by a powertrain;
• distributing the braking request to at least one of the powertrain and a brake based on the braking request and the braking force that is generable by the powertrain;
• and
• notifying a driving assistance device of information on a brake pedal operation,
• wherein, when the braking request is larger than the braking force that is generable by the powertrain, the method further includes instructing a controller of the powertrain to generate the braking force that is generable by the powertrain, and instructing a controller of the brake to generate a braking force corresponding to a difference between the braking request and the braking force that is generable by the powertrain.

A system mounted on a vehicle, the system comprising a communication device configured to receive, from a manager, a braking request,

• wherein the manager comprises one or more processors configured to:
• calculate the braking request when a driver performs an accelerator pedal operation;
• receive a braking force that is generable by a powertrain;
• distribute the braking request to at least one of the powertrain and a brake based on the braking request and the braking force that is generable by the powertrain;
• and
• notify a driving assistance device of information on a brake pedal operation
• wherein, when the braking request is larger than the braking force that is generable by the powertrain, the one or more processors are further configured to instruct a controller of the powertrain to generate the braking force that is generable by the powertrain, and to instruct a controller of the brake to generate a braking force corresponding to a difference between the braking request and the braking force that is generable by the powertrain.
