The invention discloses a vehicle body steady-state roll control method and system based on vehicle performance, electronic equipment and a vehicle. The method comprises two parts of vehicle steady-state vehicle body roll angle estimation and steady-state vehicle body roll angle control. Wherein the vehicle steady-state vehicle body roll angle estimation module comprises a signal processing module, a suspension parameter calculation module, a wheel center roll angle estimation module, a stabilizer bar real-time contribution roll moment back calculation module and a vehicle relative ground steady-state vehicle body roll angle estimation module. The steady-state vehicle body roll angle of the vehicle relative to the ground is calculated in real time through the modules and used for achieving a steady-state vehicle body roll angle control strategy. Steady-state vehicle body roll angle control comprises a signal processing module, an ideal roll angle calculation module, a whole vehicle anti-roll moment calculation module, a front and back anti-roll moment distribution coefficient calculation module and a front and back stabilizer bar torque calculation module, and the whole vehicle level performance target of the vehicle is decomposed to the system level and part level requirements through all the modules. And finally outputting the stabilizer bar torque. Steady-state vehicle body roll control of the vehicle can be achieved according to user requirements, and the driving performance of the vehicle is improved.

    本发明公开一种基于整车性能的车身稳态侧倾控制方法、系统、电子设备及车辆,包括:车辆稳态车身侧倾角估计及稳态车身侧倾角控制两部分。其中车辆稳态车身侧倾角估计包括信号处理模块、悬架参数计算模块、轮心处侧倾角估算模块、稳定杆实时贡献侧倾力矩反算模块、车辆相对地面稳态车身侧倾角估算模块。通过以上模块实时计算车辆相对地面稳态车身侧倾角,用于稳态车身侧倾角控制策略实现。稳态车身侧倾角控制包含信号处理模块、理想侧倾角计算模块、整车抗侧倾力矩计算模块、前后抗侧倾力矩分配系数计算模块、前后稳定杆扭矩计算模块,通过各模块实现车辆从整车级性能目标分解到系统级到零部件级需求上,最后输出稳定杆扭矩。本发明能够根据用户需求,实现车辆稳态车身侧倾控制,提高车辆行驶性能。
