The invention discloses a distributed chassis for an electric vehicle and a driving control method and system thereof, and belongs to the technical field of truck driving. The distributed chassis comprises a traction platform and a plurality of mounting platforms; the traction platform and each mounting platform comprise a plurality of groups of wheel assemblies; each wheel assembly in the traction platform and the mounting platform is provided with a wheel driving motor assembly and a wheel steering motor assembly in a one-to-one correspondence manner, each wheel driving motor assembly is used for independently driving one wheel assembly to rotate, and each wheel steering motor assembly is used for independently controlling the steering of one wheel assembly. According to the distributed chassis, full-degree-of-freedom mounting platform design is achieved, so that a single mounting platform can achieve the driving function of a common vehicle, and meanwhile, a distributed control system can conduct stability control over yawing and roll of the mounting platform by means of data collected by a sensor; the problems of sideslip and toppling of a large truck at present can be effectively solved, and good deployability is achieved.
本发明公开一种用于电动车的分布式底盘及其驱动控制方法、系统,属于卡车驱动技术领域,其中,分布式底盘包括牵引平台和若干挂载平台;牵引平台和每个挂载平台均包括多组车轮总成;牵引平台和挂载平台中每个车轮总成均一一对应设置有车轮驱动电机总成、车轮转向电机总成,每个车轮驱动电机总成用于独立驱动一个车轮总成转动,每个车轮转向电机总成用于独立控制一个车轮总成的转向。本发明的分布式底盘实现了全自由度的挂载平台设计,使得单挂载平台可以实现普通车辆的行驶功能,同时分布式控制系统可以依赖传感器采集数据进行挂载平台横摆和侧倾的稳定性控制,可以有效处理目前大型卡车的侧滑和倾倒问题,具有良好的可部署性。
