The present disclosure provides a vehicle parameter determination method, a torque distribution method, a system, and a vehicle. The method comprises: according to a torque range of an electric drive assembly at a first voltage and a torque control precision threshold of the electric drive assembly, respectively determining front-wheel drive torque distribution coefficient ranges corresponding to multiple test points; for any test point, according to efficiency data of the electric drive assembly at the first voltage, determining, from the front-wheel drive torque distribution coefficient range corresponding to the test point, an optimal torque distribution coefficient corresponding to the test point to obtain an optimal torque distribution coefficient map at the first voltage; using a method the same as that for obtaining an optimal torque distribution coefficient relationship at the first voltage to obtain optimal torque distribution coefficient maps at multiple other voltages; and according to the optimal torque distribution coefficient maps at the first voltage and the multiple other voltages, obtaining an optimal torque distribution coefficient map of the electric drive assembly.
