Performance of distributed driving electric vehicle is discussed in the paper, and driving characteristic test is performed to a prototype as research object on four-wheel drum dynamometer, which demonstrates less than 12 seconds of 0~100 km acceleration, maximum vehicle speed of over 150 km/h of the electric vehicle. To improve vehicle energy utilization rate and extend driving range, driving energy optimization method is put forward, which is analyzed under multiple torque distribution strategies by simulation and comparison. The results show that the proposed optimization can reduce energy consumption of 3.41%, thus improve vehicle driving efficiency and extend driving range.
