Description

METHOD AND SYSTEM FOR INTRUSION MONITORING OF A MOTOR
VEHICLE
TECHNICAL FIELD
The invention relates to a method for intrusion monitoring of a motor vehicle according to the preamble of claim 1 . The invention relates also to a system for intrusion monitoring of a motor vehicle according to the preamble of claim 9. The invention relates also to a motor vehicle.
BACKGROUND
Intrusion in the form of break-in and theft in vehicles such as trucks, trailers and semitrailers is a substantial problem. Valuable goods are currently transported by road in a relatively unprotected way and many thefts take place in transit between, for example, different warehouses. A commonly occurring method of theft is that cargo is stolen when the vehicle is parked at the side of the road and the driver is asleep in the cab. To warn of intrusion, such vehicles are equipped with alarm systems which attract attention in the surroundings and scare off the intruder by means of acoustic and lamp signals. However, such systems do not indicate the cause of the intrusion OBJECT OF THE INVENTION
An object of the present invention is to propose a method for intrusion monitoring of a motor vehicle which effectively improves protection against intrusion and enhances drivers' sense of security. A further object of the present invention is to propose a system for intrusion monitoring of a motor vehicle which effectively improves protection against intrusion and enhances drivers' sense of security. SUMMARY OF THE INVENTION
These and other objects indicated by the description set out below are achieved by a method and a system for intrusion monitoring of a motor vehicle and by a motor vehicle of the kind indicated in the introduction which further exhibit the features indicated in the characterising parts of the attached independent claims 1 , 9 and 17. Preferred embodiments of the method and the system are defined in the attached dependent claims 2-8 and 10-16. According to the invention, the objects are achieved with a method for intrusion monitoring of a motor vehicle, comprising the step of monitoring and indicating intrusion pertaining to the vehicle, and further comprising the step, when any intrusion is detected and indicated, of activating detection and visual presentation of the cause of the thus monitored and indicated intrusion. The detection is done by means of a camera system comprising a number of camera units, wherein each camera unit comprises a wide angle lens, wherein the camera units are so arranged that their fields of vision overlap one another. Improved protection against intrusion is thus made possible in that, for example, the driver will be able to see its cause. The fact that activation of the cause only takes place when intrusion occurs makes the method effective.
According to an embodiment of the method, the step of detecting and visually presenting said cause involves use of camera means, making it possible at the actual time of the intrusion to provide images of the intruder and the location of the intrusion. According to an embodiment of the method, said visual presentation involves use of display means which by visually presenting the cause of the intrusion make it easy, for example, for the driver to see the cause and the intruder. According to an embodiment, the method comprises the step of providing said display means in the driver's space of the vehicle, making it possible for him/her to see from that space the cause of the intrusion and the intruder. This results in an enhanced sense of security for the driver when he/she, e.g. in a truck, is resting or spending the night in the driver's space/cab.
According to an embodiment, the method comprises the step of sending information about said detection and visual presentation to an external unit, making it possible to identify and present externally, i.e. without physical presence, the cause of the intrusion and any intruder.
According to an embodiment of the method, said external unit comprises an alarm centre, making it possible for action to be taken quickly to prevent/hinder continuation of the intrusion and to facilitate apprehension of the intruder.
According to an embodiment of the method, said external unit uses the internet, making it possible at a distance, without physical presence, to identify and present the cause of the intrusion via an internet portal. According to an embodiment, the method comprises the step of recording results of said detection and visual presentation, making it possible to subsequently analyse the visual presentation in order to identify causes and any intruders. According to the invention, the objects are also achieved with a system for intrusion monitoring of a motor vehicle, comprising means for monitoring and indicating intrusion pertaining to the motor vehicle, and further comprising means, when any intrusion is detected and indicated, for activating detection and visual presentation of the cause of the thus monitored and indicated intrusion. Improved protection against intrusion is thus made possible in that, for example, the driver will be able to see its cause. The fact that activation of the cause only takes place when intrusion occurs makes the method effective.
According to an embodiment of the system, said means for detecting and visually presenting said cause involve the use of camera means which make it possible at the actual time of the intrusion to provide images of the intruder and the location of the intrusion.
According to an embodiment of the system said visual presentation involves use of display means which by visually presenting the cause of the intrusion make it easy, for example, for the driver to see its cause and the intruder.
According to an embodiment of the system said display means are provided in the driver's space of the vehicle, making it possible for him/her to see from that space the cause of the intrusion and the intruder. This results in an enhanced sense of security for the driver when he/she, e.g. in a truck, is resting or spending the night in the driver's space/cab.
