The invention relates to the technical field of automobile control systems, and discloses a distributed driving electric automobile hierarchical control system which comprises a parameter acquisition and state identification module, and the sending end of the parameter acquisition and state identification module is connected with the receiving end of a control target module, the receiving end of a mode hierarchical controller and the receiving end of a whole automobile management module. The sending end of the control target module is connected with the receiving end of the mode layering controller, and the mode layering controller is in two-way communication connection with the whole vehicle management module. In the running or parking process of the electric automobile, multiple items of information such as the whole automobile mass, the running gradient, the longitudinal automobile speed, the road adhesion coefficient and the eccentric angle coefficient are collected in real time, and then the mode layering controller conducts multi-mode layering control on the electric automobile through the information transmitted by the mode layering controller. And the braking performance of the automobile is maximized on the premise that the safety of the electric automobile is met.

    本发明涉及汽车控制系统技术领域,公开了一种分布式驱动电动汽车分层控制系统,包括参数采集及状态辨识模块,所述参数采集及状态辨识模块的发送端分别与控制目标模块、模式分层控制器和整车管理模块的接收端相连接,所述控制目标模块的发送端与模式分层控制器的接收端相连接,所述模式分层控制器与整车管理模块建立双向的通信连接。通过在电动汽车行驶或者驻车的过程中,实时采集整车质量、行驶坡度、纵向车速、路面附着系数以及偏心角系数等多项信息,然后模式分层控制器通过其传输过来的进行对电动汽车进行多模式的分层控制,在满足了电动汽车安全性的前提下同时还最大化汽车的制动性能。
