The invention discloses a vehicle rollover prevention control system based on a drive-by-wire chassis. The vehicle rollover prevention control system comprises a vehicle driving information detection unit, a vehicle rollover danger index calculation unit, a vehicle rollover prevention judgment unit and a vehicle rollover prevention execution unit. Wherein the vehicle driving information detection unit is used for acquiring the real-time vehicle speed, the vehicle body roll angle, the lateral acceleration, the wheel vertical load and the tire lateral deviation force of a vehicle; the vehicle rollover risk index calculation unit is used for calculating a transverse load transfer rate, a transverse load offset coefficient and a transverse load excitation index so as to obtain a rollover risk index; the vehicle anti-rollover judgment unit is used for judging and controlling whether the anti-rollover system executes control work or not, wherein the control mode comprises a single control working mode and a combined control mode; the vehicle anti-rollover execution unit comprises a steering-by-wire system, a brake-by-wire system and an active suspension system, and different control systems are controlled according to different control modes.
