The invention relates to the technical field of automotive electronics, in particular to an anti-electromagnetic interference vehicle-mounted controller circuit. A processor of a vehicle-mounted controller is provided with a plurality of external input and output interfaces, and a protection circuit is arranged between an external input connector of the vehicle-mounted controller and each external input and output interface. The protection circuit comprises a transient voltage suppressor (TVS), a magnetic bead, a capacitor, an amplitude limiter and a filter. On the premise that normal work of an electric control system is not affected, pulse absorption, microwave amplitude limiting and EMI filtering technologies are comprehensively utilized, the protection effect of surge protection first and then filtering suppression is achieved on the whole, and a protection circuit with a better anti-interference effect is achieved.

    本发明涉及汽车电子技术领域,具体涉及一种抗电磁干扰的车载控制器电路,车载控制器的处理器上设有多个外部输入输出接口,车载控制器的外部输入连接器与各个外部输入输出接口间均分别设有一个防护电路,所述防护电路包括瞬态二极管TVS、磁珠、电容、限幅器和滤波器。以不影响电控系统正常工作为前提,综合运用脉冲吸收、微波限幅和EMI滤波技术,总体上达到先浪涌保护后滤波抑制的保护效果,实现抗干扰效果更好的防护电路。
