Control Strategy for Double Motor Electric Vehicle Ⅳ

  It can be seen that the acceleration time from 0 to 50 kilometers per hour is 5.759 seconds. The acceleration time from 0 to 80 kilometers per hour is 8.359 seconds. The maximum gradeability is 30.54 percent. The maximum velocity is 118 kilometers per hour. The driving mileage of the double motor vehicle is shown in Table 3.

  It can be seen that the longest mileage is the front wheel drive, and the shortest mileage is the four wheel drive. The mileage of WLTC is shorter than the NEDC, because the WLTC contains more transient conditions.

  In the article, the battery energy management strategy is proposed by the use of instantaneous optimization algorithm for optimal driving efficiency. The all wheel drive control strategy is put forward. The simulation results show that four-wheel drive has better dynamic performance and less economic performance.
