Vehicle onboard safety system

摘要

Vehicle onboard safety systems against deception during driving-under-influence (DUI) test, using cheiloscopy sensor or bite mark sensor as biometrics have been invented. The systems have an engine interlock system, which controls the engine ignition based on the onboard DUI testing result. The systems also have a smart phone locker designed to take the smart phone away from the driver in order to avoid any driving distraction, while allowing connection to external network and resource through tethering.

主权项

1. A vehicle onboard safety system comprising:
a DUI testing unit closely coupled with a cheiloscopy sensor to collect an intended driver's lip print as biometrics while taking DUI test; a central control unit (CCU) to manage the system; a storage device with pre-stored authorized driver's or drivers' lip print biometrics and DUI limited values, which are used by said CCU to do a comparison with the data collected from said DUI testing unit; an engine ignition interlock system controlled by said CCU based on said comparison; a sensor system to ensure said intended driver, who takes and passes the test on said DUI testing unit before engine starts is the one who drives the vehicles.
