The invention provides a smooth trajectory planning and anti-skid cooperative control system for a four-axis global vehicle. The smooth trajectory planning and anti-skid cooperative control system comprises a signal input preprocessing module, a reference trajectory planning module and a wheel torque control module, the signal input preprocessing module is used for collecting and preprocessing the control expectation instruction and the vehicle state information to obtain an input signal; the reference trajectory planning module is used for planning an executable reference trajectory in real time according to the input signal in combination with physical constraints of vehicle movement and calculating a tracking reference value according to the executable reference trajectory, and the reference value at least comprises a reference rotating speed and a reference yaw velocity; and the wheel torque control module is used for tracking the reference trajectory, calculating the control torque of each wheel in real time in combination with the dynamic state of vehicle motion, and issuing the control torque to the corresponding wheel. According to the invention, global vehicles can stably run, and the situations of vehicle instability, overturning and collision damage are avoided.
