摘　　要：当前高级驾驶辅助功能多采用车身稳定控制系统(electronic stability program,ESP)完成主动建压功能。但受限于ESP建压特性,其最大建压能力和建压响应时间等性能指标都难以满足高级驾驶辅助功能需求。而线控电子液压制动(electro-hydraulic braking,EHB)系统拥有优良的液压控制性能。基于此,文中针对车辆纵向制动控制展开了研究。开发了基于Kalman算法的坡度估计算法,提升车辆纵向减速度控制算法鲁棒性;使用模糊PID的控制方案,在整车层面提高减速度控制响应时间和鲁棒性。实车验证表明所开发算法的有效性。Currently,advanced driver assistant system(ADAS)mostly adopts electronic stability program(ESP)to complete the active pressure building function.However,due to the construction pressure characteristics of ESP,its maximum construction pressure capacity and response time are difficult to meet the functional requirements of ADAS.Wire controlled electronic hydraulic braking system(EHB)has excellent hydraulic control performance.Based on this,the vehicle longitudinal brake control was researched.The slope estimation algorithm based on Kalman algorithm was developed to improve the robustness of the vehicle longitudinal deceleration control algorithm.The fuzzy PID control scheme was used to improve the response time and robustness of deceleration control at the vehicle level.Real vehicle verification shows the effectiveness of the algorithm developed.
