New energy automobile braking system braking force compensation control method and device

The invention discloses a new energy automobile braking system braking force compensation control method and device. The method comprises the steps that a brake pedal displacement signal, a brake pedal displacement change rate signal, an actual braking deceleration signal, a whole automobile mass signal and a power assisting motor target current control signal in an electric booster are obtained from a whole automobile controller through a CAN bus; the method comprises the following steps: acquiring a seat pressure signal and an ESP inner wheel cylinder target oil pressure control signal, calculating a power-assisted motor target correction current control signal and an ESP inner wheel cylinder target correction oil pressure control signal on line, judging a driving state by utilizing the seat pressure signal, and adaptively compensating the braking force of a braking system according to the size of a critical threshold value. The multi-mode intelligent driving experience feeling is met, and whether braking f
