The invention provides a signal acquisition method and device and an automobile, and relates to the technical field of automobiles. The signal acquisition method comprises the steps of sending a control instruction to an analog switch circuit, the analog switch circuit comprises a plurality of signal input ends and a signal output end, and the signal input ends are connected with a plurality of signal collectors respectively; and gating connection between one of the plurality of signal input ends and the signal output end according to the control instruction, and outputting a signal collected by the corresponding signal collector. The acquisition signals acquired by the plurality of signal acquisition devices are collected together through the analog switch circuit, and the control signals are sent to the signal acquisition devices, so that the purpose of performing time-sharing acquisition by using one AD channel of the vehicle control unit is realized, and the utilization rate of acquisition channel resources of the vehicle control unit is improved.

    本发明提供了一种信号采集方法、装置及汽车,涉及汽车技术领域。该信号采集方法包括:向模拟开关电路发送控制指令,其中所述模拟开关电路包括多个信号输入端和一个信号输出端,所述多个信号输入端分别与多个信号采集器连接;根据所述控制指令,选通所述多个信号输入端中的一个与所述信号输出端之间的连接,输出对应的信号采集器所采集到的信号。通过模拟开关电路对多个信号采集器采集的采集信号归到一起,向其发送控制信号,实现了使用整车控制器的一个AD通道进行分时采集的目的,从而提高了整车控制器采集通道资源的利用率。
