Abstract: In order to acquire a high efficiency and low cost in-wheel motor of micro-electric vehicle, a new driving in-wheel motor was optimized and designed. The simple genetic algorithm and pattern search method applied in driving in-wheel motor of the optimum design were introduced. The disadvantages of these two methods that the effects of optimization design were non-significant were pointed out, and an improvement genetic algorithm based on these was put forward. On the basis of the study of the in-wheel motor of micro-electric vehicle and in the light of the design features of driving in-wheel motor, a new mathematical model of driving in-wheel motor optimization design was established, and a living example was optimized and computed. The results show that the efficiency of the driving in-wheel motor is improved, and the cost are decreased, which can satisfy the using requirements of driving in-wheel motor of micro-electric vehicle. Therefore, the improvement genetic algorithm is an ideal algorithm in optimization design of driving in-wheel motor, which has a wide range of engineering application.
