Abstract:

By using a self-designed one-way coil solenoid valve in the engine intake pipe,and using SCM a password security system of a car was developed with the keyboard and type. Through installing digital keyboard multi-function steering wheel,the car open password was inputted and judged to be correct or not then to control opening and closing of the engine gas path, so as to achieve the vehicle anti-theft feature. Simulating the security system with the developed SCM slabs, the experimental results show that the password security system is safe and reliable,inexpensive, easy to conceal, and can effectively reduce the rate of car theft.
