The Driving Control of Pure Electric Vehicle

Pure electric vehicle has become the representative of new energy source auto because of its low level of environmental pollution, noise, high efficiency, availability of multiple energy resources, and ability of energy feedback. Pure electric vehicle is driven by motor, with no reduction gears in the scope of fixed torque and fixed power. It can also generate torque in the low speed scope, and can work under the way of fixed power using field-weakening control in the high speed scope. This paper analyzes the advantages and disadvantages of traditional drive mode, motor-driving axle combined drive mode, motor-driving axle integrated drive mode, and wheel-hub motor drive mode. The electric wheel driving vehicle gradually becomes a new direction of pure electric vehicle relying on its great advantage in the 4 driving modes.
