The invention discloses a four-wheel drive vehicle-based moment of force distribution control system. The four-wheel drive vehicle-based moment of force distribution control system comprises an ECU (Electronic Control Unit), wheel rotating speed sensors, a steering wheel rotating angle sensor, a vehicle body speed sensor, a hydraulic control brake, a yaw velocity sensor and an inter-axis electric control limited slip differential, wherein all of the wheel rotating speed sensors, the vehicle body speed sensor, the yaw velocity sensor and the steering wheel rotating angle sensor are connected with the input end of the ECU; both the inter-axis electric control limited slip differential and the hydraulic control brake are connected with the output end of the ECU. According to the four-wheel drive vehicle-based moment of force distribution control system, a vehicle shows high dynamic performance and operating stability after moment of force distribution comprehensive control and inter-axis moment of force distribution control are applied to the vehicle, so that the four-wheel drive vehicle-based moment of force distribution control system has high practicability in the application of improving the traction trafficability, the directional stability or the steering maneuverability of the vehicle.
