The invention discloses a full-vector drive-by-wire chassis coordination control system which comprises a main controller, a sub-controller, a detection module, a suspension module and a driving module, the sub-controller, the detection module, the suspension module and the driving module are connected with the main controller, and the main controller is responsible for regulating and controlling power distribution of a chassis and dynamic coordination of four electric wheels; the sub-controller can independently control steering and braking of a single electric wheel. The coordinated control system for the full-vector drive-by-wire chassis has the beneficial effects that the main controller can clean and process road conditions fed back by the detection module, then a road condition model is produced, the sub-controller, the suspension module and the driving module are matched, hubs of an automobile can be adjusted in advance when encountering corresponding road conditions, and the driving efficiency of the automobile is improved. The height of the air suspension is changed, it is guaranteed that the suspension powerfully supports a vehicle body, the overall control difficulty of a chassis is lowered, the stability of the chassis is improved, and meanwhile friction or collision between the chassis and ground foreign matter can be avoided.
本发明公开了一种全矢量线控底盘的协调控制系统,包括:主控制器以及与主控制器相连接的子控制器、检测模块、悬架模块和驱动模块,所述主控制器,负责调控底盘的动力分配和4个电动车轮的动态协调;所述子控制器,能够独立控制单个电动车轮的转向、制动控制。其有益效果是,该全矢量线控底盘的协调控制系统,通过主控制器能够将检测模块反馈的路况清理进行处理,进而生产路况模型,搭配子控制器、悬架模块和驱动模块,能够使得汽车的轮毂遇到相应的路面状况时,提前做好调整,改变空气悬架的高度,既保证悬架对于车身的有力的支撑,又使得底盘整体的控制难度降低,提高了其稳定性,同时还能避免底盘与地面异物发生摩擦或碰撞。
