The invention discloses a yaw and roll stability integrated control system for a distributed driving electric vehicle. Comprising an information acquisition module, a yaw stability threshold calculation module, a yaw instability risk judgment module, a roll stability threshold calculation module, a roll instability risk judgment module, an integrated control additional yaw moment calculation module and an integrated control execution module. According to the invention, the information acquired by the information acquisition module is utilized to calculate the threshold value of the stability related parameter and judge the instability risk condition of the vehicle, the appropriate integrated control mode is selected according to the instability risk condition, and the integrated control additional yaw moment considering both the yaw stability and the roll stability of the vehicle is calculated. And the torque of each wheel is reasonably distributed, so that the integrated control of the distributed driving electric vehicle on the yaw stability and the roll stability is realized, the requirements of the vehicle on the yaw stability and the roll stability under different working conditions are met, and the driving safety of the vehicle is improved.

    本发明公开了一种分布式驱动电动汽车横摆与侧倾稳定性集成控制系统,包括信息采集模块、横摆稳定性阈值计算模块、横摆失稳风险判断模块、侧倾稳定性阈值计算模块、侧倾失稳风险判断模块、集成控制附加横摆力矩计算模块和集成控制执行模块。本发明利用信息采集模块获取的信息,计算稳定性相关参数的阈值并判断车辆的失稳风险状况,根据失稳风险状况选择合适的集成控制模式,计算出兼顾车辆横摆稳定性与侧倾稳定性的集成控制附加横摆力矩,并合理地分配各个车轮的力矩,以实现分布式驱动电动汽车对横摆稳定性与侧倾稳定性的集成控制,满足车辆在不同工况下对横摆稳定性和侧倾稳定性的要求,提高车辆的行驶安全性。
