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 force recession caused by brake disc abrasion and brake fluid leakage factors is rapidly compensated or not can be selectively judged; the system is simple in structure and low in cost, and driving safety can be improved by combining driving state recognition and braking force compensation control.

    本发明公开了一种新能源汽车制动系统制动力补偿控制方法及装置包括:通过CAN总线从整车控制器中获取的制动踏板位移信号、制动踏板位移变化率信号、实际制动减速度信号、整车质量信号、电动助力器内助力电机目标电流控制信号、座椅压力信号和ESP内轮缸目标油压控制信号,在线计算助力电机目标修正电流控制信号和ESP内轮缸目标修正油压控制信号,利用座椅压力信号判断驾驶状态,根据临界阈值大小是否进行自适应补偿制动系统制动力,不仅满足多模式智能驾驶体验感,还能有选择性的是否进行快速补偿因制动盘磨损、制动液泄露因素造成的制动力衰退;且本发明结构简单,成本低下,能够结合驾驶状态识别与制动力补偿控制提升行车安全。
