The invention discloses an automobile control system based on transverse stability analysis, which comprises transverse stability analysis, transverse control SWC, ESC and auxiliary driving, and is characterized in that the operation system is based on transverse stability analysis, transverse swing angular velocity gain is realized by controlling transverse torque, and the magnitude of the transverse torque is in direct proportion to the transverse velocity of an automobile. The vehicle stability factor is calculated through the ratio of the transverse swing angular velocity to the transverse velocity, the vehicle stability factor is calculated through the yaw angular velocity gain and the yaw angular velocity, and the vehicle stability is judged through the vehicle operation system. The transverse control SWC is responsible for converting a control instruction into actual vehicle movement, the ESC adjusts transverse stability setting of the whole vehicle through a driving or motor controller, the perception feedback and corresponding correction effect of the system on transverse stability data is improved, and perception, feedback and corresponding correction are conducted through the transverse stability data in real time.
