Car moment of torsion vector distribution system and car

The utility model provides a car moment of torsion vector distribution system and car relates to car drive field. Can not realize the problem of distribution of independent moment of torsion vector and energy recuperation difficulty and design for ordinary car in solving prior art, car moment of torsion vector distribution system includes: set up on vehicle chassis, through cardan shaft drive auto wheel's wheel limit motor, or set up on the inside wheel hub of auto wheel direct drive auto wheel's wheel hub motor, wherein, wheel limit motor or in -wheel motor's signal receiving unit receives the control signal that whole car host system sent, will control signal inputs for signal control unit, signal control unit controls according to control signal auto wheel's moment of torsion and rotational speed. The utility model discloses a balanced of energy is retrieved under the distribution of the independent moment of torsion of car and the condition of inside and outside wheel speed difference.
