摘　　要：针对车辆制动时因轴荷转移造成的前后车轮不同时抱死及舒适性不足的问题,提出了一种考虑制动意图识别的制动力分配控制策略。采用模糊控制器设计了一种七输入单输出的制动意图识别模型,为避免工程实际因素对制动器造成的制动力分配不均现象,依据识别结果提出了基于车轴载荷并通过前后车轮减速度与参考车速进行反馈修正的制动力分配控制策略。仿真结果表明,在不同路面附着条件下,所提出的策略均能满足制动力分配要求,保证车辆制动时的稳定性和舒适性。A braking force distribution control strategy considering braking intention recognition is proposed to address the problems of front and rear wheels not locking at the same time and lack of comfort caused by axle load transfer during vehicle braking. A seven-input, single-output braking intention recognition model is designed with a fuzzy controller. To avoid the uneven distribution of braking force caused by engineering practical factors, a braking force distribution control strategy based on axle load and feedback correction by front and rear wheel deceleration and reference vehicle speed is proposed based on the recognition results. The simulation results show that the proposed strat-egy can meet the braking force distribution requirements under different road surface adhesion conditions and ensure the stability and comfort of the vehicle when braking.
