重载车辆多轴多源制动协同控制方法

The invention provides a multi-axis multi-source braking cooperative control method of a heavy-duty vehicle, which at least comprises a group of hybrid braking axles which are cooperatively braked by mechanical braking and durable braking, wherein the cooperative control method of all the wheels of the same group is concretely as follows, S1, the difference value between expected braking moment of the wheels and the maximum moment of the mechanical braking is calculated and ordered, S2, the braking moment provided by the mechanical braking preferentially is used as distribution logic to distribute the mechanical braking and the durable braking, and S3, the durable braking target total moment is distributed to a durable braking actuator. In S3, the distribution of durable braking and mechanical braking is realized by using a smaller operation amount by an iterative optimization method, the braking strength can be improved, the abrasion of the mechanical braking can be reduced, unexpected overlarge braking moment of wheels can be prevented by using a distribution algorithm, and the safety of the vehicle is improved.
