Vehicle parameter determination method, device, and storage medium

An electronic device, comprising a processor and a computer-readable storage medium, wherein the computer-readable storage medium is configured to store instructions;

• and the processor, when executing the instructions, is caused to perform:
• determining, based on a torque range of an electric drive assembly at a first voltage and a torque control accuracy threshold of the electric drive assembly, front-wheel drive torque distribution coefficient ranges corresponding to a plurality of test points, wherein each of the plurality of test points is a point corresponding to a torque and a speed of the electric drive assembly, and the torque corresponding to the test point is within the torque range of the electric drive assembly;
• for any test point:
• determining, based on efficiency data of the electric drive assembly at the first voltage, an optimal torque distribution coefficient corresponding to the test point within the front-wheel drive torque distribution coefficient range corresponding to the test point, to acquire an optimal torque distribution coefficient map at the first voltage;
• acquiring, in a same manner as acquiring the optimal torque distribution coefficient map at the first voltage, optimal torque distribution coefficient maps at other voltages;
• and
• acquiring, based on the optimal torque distribution coefficient maps at the first voltage and the other voltages, an optimal torque distribution coefficient map of the electric drive assembly.
