Vehicle torque vector distribution method and system

The invention provides a vehicle torque vector distribution method and a system. The vehicle torque vector distribution method comprises the following steps: a controller obtains a control signal sent by a whole vehicle main control module; the controller is arranged on a vehicle chassis, and can drives a rim motor of a vehicle wheel through an universal joint; or the controller is arranged on an internal hub of the vehicle wheel, and can directly drive a hub motor of the vehicle wheel; and the torque and the rotating speed of the vehicle wheel are controlled according to the control signal. The method solves the problem of incapability of basically realizing independent torque distribution due to more complication of a traditional steering system, and enables a common vehicle to realize independent torque vector distribution and energy balanced recovery.
