From the view of torque controlling strategy, the relation between the torque controlling strategy such as the electric current feedback method、 PWM open loop method etc and the vehicle driving way is analyzed firstly, then the conclusion could be drawn that the PWM open loop method has more advantages than the electric current feedback method when they are both used in the same vehicle which is direct driving by hubcap motor. Secondly, based on the electric motor mathematic model and its experiment, a new permanent brushless dc motor phase electric current detector method in which a digital signal processor and single current sensor are used is introduced.

从转矩控制策略角度来看，分析了电流反馈法以及开环PWM电压调速控制方法与车辆的驱动方式关系，得出了电机驱动电压受限的情况下，无论是从对车辆的动力性能影响还是从对车辆的驱动要求来讲，开环PWM电压调速控制方法较电流反馈法更适用于以轮毂电机直接驱动方式的两轮电动车中；其次，根据电机的数学模型以及电机试验波形，提出了一种利用数字信号处理器以及单个电流传感器检测三相永磁无刷电机电枢电流的新方法，这种方法具有较强的适应性、实时性，它可以根据控制系统的要求，适时地提供所需电流数据，是目前许多文章关于无刷电机相电流平波的重要技术基础。

According to arrival rate in the upstream intersection and number of cars at the beginning of period on the road, the paper investigates the evolution of the number of cars on the road and the number of passed cars of the downstream intersection. By switching the red time of upstream signal, we can control the number of passing vehicles of downstream intersection.
