| 摘要(英文)： | A distributed driving electric automobile torque optimization of the distribution control method, relates to a distributed driving torque distribution control method for the electric automobile. Solves the problem that the existing four-wheel driving torque distributed driving electric automobile tire wear there are distribution mode, electric automobile problem of poor stability of operation. The invention adopts a pressure sensor detecting a tire vertical load, a vehicle speed sensor detecting a tire transverse speed, a speed sensor detecting a tire speed; sending a signal to the vehicle controller; the controller utilizing the received signal to calculate the correlation parameter of the operation of the electric vehicle and tire wear in power; in with the tire wear and related parameter and power, calculate four driving of the electric automobile of the motor such as the torque, power minimum value obtained when the tire wear, four of the motor such as the torque distribution control of objective function; four obtained in accordance with the constraint conditions of the drive motor in the function of the drive torque. This invention is suitable for the distributed driving electric automobile torque distribution control. | ||
