混合动力汽车电子换挡手柄控制信号可靠性设计

摘要

In order to meet the control reliability requirement of hybrid vehicle electronic shift handle signal, based on analyzing the structure and signal control logic of the handle, the reliable control method was designed by signal processing and strategy redundancy algorithm. Through the establishment of the system control model with Simulink and the usage of rapid control prototyping approach with MotoTron, the control method of the shift handle signal was tested to verify its reliability. Test results showed that the control method could meet the shifting demand for hybrid vehicle, and the control reliability of the shift handle signal and traffic safety could be ensured.%基于混合动力汽车电子换挡手柄的结构和信号控制逻辑,通过信号故障处理和策略冗余算法,设计了电子换挡手柄信号的可靠性控制方法,通过建立Simulink控制模型,并采用快速控制原型的方式对换挡手柄信号控制进行仿真测试,验证控制的可靠性.测试结果表明该控制方法满足了混合动力汽车的换挡需求,并保证了换挡手柄信号控制的可靠性及车辆行驶安全.
