Module 28 includes being used to detect the alcohol sensor 281 and signal processing circuit 282 of the alcohol content of driver's exhaled gas,
Signal processing circuit 282 electrically connects with vehicular control unit ECU1.Collecting unit 2 also includes, facial image acquisition recognition unit
29 include infrared pick-up first 291 and the image processing module 292 being connected with infrared pick-up first 291, image processing module
292 electrically connect with vehicular control unit ECU1.Physiological parameter acquisition module is contactless physiological parameter sensors, and is arranged on
The physiology ginseng such as steering wheel outer shroud (handle), heart rate, change rate of heartbeat and the respiratory rate of physiological parameter sensors collection driver
Number information.
Operation principle：
Apart from induction module 21, wheel speed sensors 22, infrared ray sensor 23 in real time by the data transfer of monitoring to vehicle-mounted
Control unit ECU1, the vehicle speed information and range information compared through vehicular control unit ECU1 are respectively smaller than braking speed letter
Breath and braking spacing information and when brake signal experiences module 32 and do not produce brake signal, vehicular control unit ECU1 control systems
Dynamic operation module 24 carries out brake operating to vehicle；
When vehicular control unit ECU1 detects driver's seat nobody and vehicle-mounted control according to front seat pressure sensor 31
Unit ECU1 detects current gear when being drive shift or reverse drive gear, and control brake operating module 31 is braked to vehicle；
