摘要
电动转向系统的关键技术是确定在不同车速、方向盘扭矩下的电机助力扭矩。考虑到其较复杂的非线性特性,采用了利用BP网络的非线性逼近特性对电机助力曲线进行拟合的新方法,并在Mat-lab中设计了该BP网络模型,进行了训练拟合验证,结果显示通过该方法克服助力盲区的途径是完全可行的,对实践研发工作有一定的借鉴意义。
The power character of motor is the most crucial technology. Considering the complicated nonlinear character of the torque supplied by motor, the BP network is designed, and the effect shows that blind zone of torque is overcome. these solutions are effective. It will be covered and adopted by the future development.
