The invention discloses a torque vector control system for a hub motor four-wheel-drive automobile. A driving style identification module of the torque vector control system judges the driving style of a driver in the running process of the hub motor four-wheel-drive automobile; the vehicle state sensing module obtains the steering wheel turning angle and the vehicle longitudinal speed in real time and conducts fault state monitoring on the hub motor four-wheel-drive vehicle. The vehicle motion control module calculates an ideal yaw velocity target of the hub motor four-wheel-drive automobile; the torque vector control module calculates an additional yaw moment according to an ideal yaw velocity target and an actual yaw velocity, and executes a corresponding fault processing strategy according to a fault state monitoring result. And then torque distribution is performed according to the additional yawing torque in combination with a fault state monitoring result to generate an additional driving torque and an additional braking torque of each wheel. According to the invention, adaptive yaw stability control is realized for drivers with different driving styles.
