The invention belongs to the technical field of pure electric or hybrid new energy vehicle ESP (electronic stability program) and motor assembly, and provides a vehicle torque distribution control method and system based on chassis gravity buffer integration, which comprises the following steps: judging whether a vehicle turns according to the angle of a steering wheel, judging whether the chassis flatness exceeds a preset value or not, and when the vehicle turns and the chassis flatness exceeds the preset value, controlling the vehicle torque distribution control method and system. Torque distribution of corresponding wheels is increased; when the chassis flatness is adjusted and the torque distribution of the corresponding wheels is increased, according to the chassis flatness, the damping deformation degree and the chassis gravity, adjusting parameters of a torque distribution increase value are determined through multi-factor analysis, and the preset torque distribution increase amount is adjusted through the adjusting parameters; by considering the flatness of the chassis, the adaptability of the driving torque distributor to complex road conditions during working is improved, the stability is improved, the energy management accuracy during working of the driving torque distributor is improved by adjusting parameters, and the overall performance of a vehicle is guaranteed.
