DESCRIPTION:
BRIEF SUMMARY
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a method and to an arrangement for remotely controlling one or more of the functions of a motor-driven vehicle. More particularly, the invention is concerned with fully or partially deactivating and activating a motor-driven vehicle by remote control.
2. Description of the Related Art
By partial or total deactivation of a vehicle is meant the deactivation of all vehicle functions or facilities, from the locking of certain parts of the vehicle to rendering the vehicle inoperable. By activating the vehicle is meant to bring the vehicle to an operable state from an inoperable state.
The theft of vehicles in society is progressively increasing. Furthermore, it is becoming progressively more common for the return of leasing cars and rented cars to be delayed beyond the date agreed, or for such cars not to be returned at all. There is a serious need for the prevention of theft and unauthorized use of motor-driven vehicles.
Theft against security vehicles is also becoming more usual. Naturally, there is a serious need to prevent theft or robbery of this nature.
The theft of leisure boats has also increased. Such boats are often very valuable and the possibility of finding a stolen boat is relatively limited.
The object of the present invention is to enable these problems to be greatly reduced.
SUMMARY OF THE INVENTION
The present invention thus relates to a method for remotely controlling one or more of the functions or facilities of a vehicle, and is characterized by transmitting a first coded signal with the aid of a cordless transmitter, this signal being received in a receiver in the vehicle; by including in the receiver a signal decoding means which detects and identifies said code and compares the code with a code that is specific to the vehicle concerned; and causing the receiver to activate, through the agency of a control circuit, one or more electronic circuits in the vehicle when agreement is found between the received code and the vehicle specific code in a manner such as to render one or more of the vehicle functions inoperable.
The invention also relates to apparatus for carrying out the method.
BRIEF DESCRIPTION OF THE DRAWINGS
The invention will now be described in more detail with reference to exemplifying embodiments thereof and also with reference to the accompanying drawings, in which
FIG. 1 is a block schematic which illustrates one embodiment of the invention;
FIG. 2 illustrates another embodiment of the invention; and
FIG. 3 illustrates a further embodiment of the invention.
DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention can be applied to all sorts of motor-driven vehicles, such as automobiles, lorries, trucks and transport vehicles, craft, etc., and it will therefore be understood that the invention is not restricted to any particular type of vehicle, although the invention is primarily described in the following with reference to automobiles, security transport vehicles and leisure craft.
FIG. 1 illustrates one embodiment of an inventive arrangement. The arrangement illustrated in FIG. 1 is intended to be installed in a vehicle in which the invention is applied.
The arrangement is intended to remotely control one or more of the functions of a vehicle. These functions may include one or more of the functions required to drive the vehicle. For instance, one function may involve the supply of current to the vehicle engine or to the engine fuel system. In the case of modern cars equipped with a so-called inboard computer, the computer may be programmed so that selective vehicle functions can be rendered non-functional by means of the arrangement.
Another example is that one or more functions can be added to a vehicle and these further functions can be remotely controlled by means of the inventive arrangement. For instance, the electrically maneuverable locks of the vehicle doors and windows installed in the vehicle may be constructed so that doors and windows can be remotely locked
