The invention provides a device for detecting vital signs in a car. The device comprises a micro electronic accelerometer which is arranged in a car body and used for detecting heartbeat of people in the car and converting the heartbeat into a pulse signal, a power amplifier which is connected to the output end of the micro electronic accelerometer and used for performing power amplification for the pulse signal, an A/ D converter which is connected to the output end of the power amplifier and used for converting the pulse signal from an analog form into a digital form, and a controller for receiving the pulse signal in the digital form, comparing the pulse signal with the pre-stored heartbeat range value after receiving a car closing locking signal and then outputting a control signal, and an alarm which is connected to the controller to generate alarming voice according to the control signal.
