The invention provides a vehicle motion control system, a pitching control unit and a control method. The pitch control unit includes: a detection module configured to detect whether a requested braking level is greater than a braking threshold level; a first calculation module configured to calculate an actual pitching state and a target pitching state of the vehicle when the detection result is positive; the second calculation module is configured to calculate a first pitching moment by adopting a feedforward control algorithm and calculate a second pitching moment by adopting a feedback control algorithm; and the third calculation module is configured to calculate a plurality of adjusting forces according to the first pitching moment and the second pitching moment, and the adjusting forces are respectively used for adjusting forces generated by actuators, coupled with the wheels, of the full-active suspension system, so that the actual pitching state of the vehicle is close to the target pitching state as much as possible or consistent with the target pitching state as much as possible.
本发明提供了一种车辆运动控制系统、俯仰控制单元和控制方法。俯仰控制单元包括:检测模块,配置成检测请求的制动水平是否大于制动阈值水平;第一计算模块,配置成在检测结果为肯定时,计算车辆的实际俯仰状态和目标俯仰状态;第二计算模块,配置成:采用前馈控制算法计算第一俯仰力矩,以及采用反馈控制算法计算第二俯仰力矩;以及第三计算模块,配置成:根据第一俯仰力矩和第二俯仰力矩计算多个调节力,分别用于调节全主动式悬架系统的与各车轮耦接的执行器产生的力,以使得车辆的实际俯仰状态尽量接近目标俯仰状态或与目标俯仰状态一致。
