| 摘 要： | 针对某六缸气体机电控系统，选择Infineon XC2785芯片作为微控制器，采用MC33810作为点火预驱动芯片设计了一套点火驱动。利用曲轴和凸轮信号进行相位信号分析与判断，以诊断得转速传感器工作是否正常。根据所判断的转速传感器信号正常或缺失情况，设计相应的点火输出控制策略。利用曲轴和凸轮轴进行压缩上止点相位判断并进行点火正时控制。根据转速的高低所带来的不同曲轴转角延迟，设计了数齿及计时的点火输出策略。最终通过试验验证了该算法的可行性。

| Abstract: | In view of the electrical control system of a 6 cylinder gas machine,we selected Infineon XC2785 as the micro control union and designed a set of ignition driven based on MC33810.Through the analysis and diagnosis of crankshaft and camshaft signal,ECU could judge the state of speed sensor. According to the judgment of normal or missing state of speed sensor signal,we designed the corresponding output ignition control strategy.ECU used the crankshaft and camshaft signals to judge the compression TDC and controlled the ignition timing.According to the different crankshaft rotation delay on account of different rotating speed,the ignition output strategy of counting teeth and timing was designed.Finally the feasibility of the algorithm was verified by experiment. |
