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.
