  • Publication number: 20220242378
    Abstract: A braking control system includes control circuitry configured to control first and second brakes in a vehicle. The control circuitry is configured to calculate a target braking force in accordance with the operation amount of a brake pedal by a driver, determine a first braking force and a second braking force based on the target braking force, and control each of the first and second brakes such that each of the determined braking forces is generated in the vehicle. The first and second braking forces are determined such that a sum of the first and second braking forces becomes the target braking force and a pitch behavior specified by a preset pitch behavior model occurs in the vehicle.
