Research on Gear Decision Technology for Pure Electric Bus based on the Operating Routes

摘要

In order to make full use of the pure electric bus fixed route characteristic, this paper analyzes the correction algorithm of dynamic vehicle location that based on self-adaptive Kaltman filter. A method of curve and ramp recognition based on vehicle driving position and line features is proposed and ultimately determines the comprehensive shift strategy of the pure electric bus that based on fixed routes. In order to verify the correctness of the control strategy, the authors develop a pure electric vehicle with the AMT, and conduct the real vehicle verification experiment. Experimental results show that the control strategy can well identify the corners and ramps, and avoid the cycle shift, and finally improve the ride comfort of the vehicle.
