Theft-proof system and method for vehicle

Abstract

The invention relates to a vehicle anti-theft system and a method. An on-vehicle host downloads a unique identifier as a control identifier from a customer service center and stores the identifier as a component identifier into at least a component. When a vehicle is started, the on-vehicle host judges whether the control identifier is obtained; if yes, the on-vehicle host gives an inquiry command to at least a component so as to obtain a component identifier and then judges whether the component identifier is in line with the prestored control identifier of the on-vehicle host; if yes, the on-vehicle host generates a normal operation signal to work normally and transmits the control identifier back to the customer service center; subsequently, the customer service center compares the control identifier with a theft database; if the vehicle is found a theft vehicle, follow-up processing is carried out; if not, the on-vehicle host generates an abnormal signal and transmits the signal to the customer service center, which then implements follow-up processing.

Description

technical field [0001] The invention relates to the technical field of anti-theft, in particular to a vehicle anti-theft system and method. Background technique [0002] Currently, the vehicle anti-theft system on the vehicle generally includes a vehicle battery, a buzzer and an anti-theft host, wherein the anti-theft host is electrically connected to a plurality of sensors. The aforementioned vehicle battery is electrically connected to the buzzer and the anti-theft host respectively to provide power to the buzzer and the anti-theft host. In the normal anti-theft mode, if one of the sensors generates a sensing signal due to an abnormal situation (for example: the vehicle is towed, the vibration sensor will sense that the vehicle is currently subject to severe vibration), the sensor will send the generated signal The sensing signal is sent to the anti-theft host, so that the anti-theft host controls the buzzer to emit a warning sound and controls the lights to flash.

AI Technical Summary

Problems solved by technology

However, when any part / accessory in the vehicle is stolen, it will cause the car owner to be unable to start the vehicle smoothly, and the stolen part / accessory cannot be traced back, and since each identification element has a unique individual identification Therefore, when the number of vehicle parts is large, the vehicle anti-theft system must have a large-capacity storage medium to store the identification codes, and when the parts are stolen, the identification code cannot be used to trace the stolen vehicle.

At the same time, when a new device is added to the vehicle (for example: car audio and video playback system), since the new device does not have an identification code, it needs to be returned to the maintenance yard for installation at this time, which adds a lot of trouble to the driver
