Torque control method and system for all-wheel distributed vehicle

A torque control system for an all-wheel distributed vehicle, comprising:

• an adhesion coefficient acquisition module configured to, in response to a skidding state of a vehicle, acquire adhesion coefficients of a reference wheel and other wheels;
• a drive torque acquisition module configured to, on the basis of the adhesion coefficients of the other wheels, acquire a target drive torque for preventing the skidding of the reference wheel;
• a reference vehicle speed acquisition module configured to, in response to the reference wheel not skidding, acquire a wheel linear speed of the reference wheel, and taking the wheel linear speed as a reference vehicle speed of the vehicle;
• and
• an adjustment module configured to adjust drive torques of the other wheels on the basis of the reference vehicle speed.
