摘要
分析电动客车转向油泵电机偶发高压供电故障时,转向盘回弹打手与转向油泵电机反转导致转向油泵电机控制器烧毁的原因,并采取保护措施将故障导致的安全风险尽量降低。
The authors analyze the reasons for the phenomena of steering wheel rebounding and the controller of steering pump motor burnt down because of the steering pump motor inversing when the steering pump motor of an electric bus accidentally arises high voltage power supply failure, and take protection measures to minimize the risk of safety.
