The invention discloses an automobile intelligent drive-by-wire chassis system and an uncertainty optimization method thereof. The automobile intelligent drive-by-wire chassis system comprises a drive-by-wire steering subsystem, a drive-by-wire braking subsystem, a drive-by-wire driving subsystem and a drive-by-wire chassis domain controller. The drive-by-wire driving subsystem comprises four electric wheels and four hub motors; each hub motor is installed in the corresponding electric wheel and drives the electric wheel to work. The steer-by-wire subsystem comprises a first steering motor assembly, a second steering motor assembly, a gear rack steering gear, a steering trapezoid and a lower steering column; the brake-by-wire subsystem comprises an executing mechanism and a brake motor assembly. The executing mechanism comprises brake calipers, a transmission device and a brake disc. The drive-by-wire chassis domain controller is used for generating a control instruction of each motor;the drive-by-wire steering, drive-by-wire braking and drive-by-wire driving functions are fused, the chassis structure is simplified, chassis light weight and arrangement space optimization are facilitated, the chassis integration degree is improved, and integrated control is facilitated.

    本发明公开了一种汽车智能线控底盘系统及其不确定优化方法,包括:线控转向子系统、线控制动子系统、线控驱动子系统和线控底盘域控制器;线控驱动子系统包括:四个电动轮和四个轮毂电机;各轮毂电机分别安装于各电动轮内,并驱动电动轮工作;线控转向子系统包括:第一转向电机总成、第二转向电机总成、齿轮齿条转向器、转向梯形及下转向柱;线控制动子系统包括:执行机构和制动电机总成,执行机构包括:制动卡钳、传动装置及制动盘;线控底盘域控制器用于产生各电机的控制指令;本发明融合了线控转向、线控制动、线控驱动功能,简化了底盘结构,有助于底盘轻量化和布置空间优化,提高了底盘集成化的程度,有利于集成一体化控制。
