摘要： A method of assisting deceleration during a stop of a motor vehicle having a drivetrain including a traction motor, a road wheel operatively connected to the drivetrain, a friction brake configured to decelerate the road wheel, and an electronic controller includes detecting, via the electronic controller, a request to stop the vehicle. The method also includes commanding the traction motor to provide regenerative braking in response to the request to stop the vehicle. The method additionally includes determining a current vehicle operating state. The method also includes determining an amount of brake drag torque to be generated by the friction brake based on the current vehicle operating state. The method further includes commanding an application of the determined amount of the brake drag torque in parallel with the regenerative braking, thereby operating the friction brake as a mechanical drivetrain damper while assisting the regenerative braking to stop the motor vehicle.

摘要： Disclosed is a brake control apparatus which includes a brake booster for augmenting deceleration, and which addresses the problem in conventional brake control apparatuses that deceleration and pedal reaction force depend on driver brake pedal input, and thus the pedal response and the ride comfort from the feeling of deceleration are affected by the manner in which the brake pedal is actuated by the driver. The brake control apparatus comprises a pedal reaction force generation unit for generating a pedal reaction force on the brake pedal, and a brake control unit for controlling the brake force in such a way as to suppress driver brake input fluctuations, wherein the pedal reaction force generation unit suppresses pedal reaction force fluctuations in accordance with specific deceleration and pedal reaction force characteristics. The brake control apparatus further comprises a calculation unit for calculating a target deceleration on the basis of lateral acceleration information in the left-to-right direction of the vehicle, wherein the brake control unit suppresses the brake force in such a way that the target deceleration is produced and, when the amount by which the brake pedal is depressed reaches a specific amount in respect of the target deceleration, the pedal reaction force generated by the pedal reaction force generation unit may be increased.
