Description

DEVICE PROTECTING A MOTOR VEHICLE AGAINST THEFT}

In the known vehicle antitheft device that uses an alarm device through sound and / or light emission signal alone or in combination with each other, the most common is an external and internal lock device to lock the control device, as well as , Mechanical brakes for brake pedals and gear shift levers.

Not only by stopping fuel supply to the carburetor by manually or remotely controlled valves, but also by opening the vehicle ignition circuit by relays and electromagnet switches controlled by hidden switches. Vehicle antitheft devices are also known.

However, the effectiveness of these known vehicle antitheft devices is closely related to the intruder's access to the individual elements within the protection device. It should be mentioned here that this accessibility of the intruder to the elements in the known protection is substantially unlimited, especially when the vehicle door lock is overcome.

In many countries, therefore, legislation has been enacted that sets the conditions that must be met by anti-theft systems in response to an increasing number of vehicle thefts, especially in view of many years of experience in terms of the efficiency of such systems. Attempts have been made to force system manufacturers to produce drive trains, in particular safety devices that operate on gear shift control systems.
