The invention discloses an in-vehicle living body detection method and device, and the method comprises the steps: obtaining the states of a driver and passengers, and starting an infrared sensor when the driver and passengers leave a vehicle; collecting temperature information through an infrared sensor, and outputting a living body detection result based on the temperature information by adopting an infrared living body detection method; when the living body detection result is that a living body exists, starting a millimeter wave radar, and collecting a breathing micro-motion signal through the millimeter wave radar; a preset living body detection model is adopted to output a model detection result based on the temperature information and the expiration micro-motion signal; when the model detection result shows that the living body exists, outputting the model detection result to the server, and outputting the model detection result to the mobile terminal through the server; receiving a confirmation instruction input by the user through the mobile terminal; in response to a confirmation instruction input by the user, obtaining a real-time temperature output by a sensor in the vehicle; the real-time temperature is evaluated according to a preset temperature threshold value, and when the real-time temperature is larger than the preset temperature threshold value, the vehicle-mounted ventilation equipment is started.
