Abstract
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 jerk 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.
