[0002] With the improvement of living standards, the number of cars has increased significantly. At present, the way to remotely lock the car door is that the infrared waves emitted by the car key have a fixed frequency and band. When the receiver in the car receives these waves, it will Screen it to make sure it is this wave frequency, and then extract and compare the data in the wave frequency. If the comparison is successful, the controller will issue a series of instructions to unlock and lock the door. Otherwise, the comparison fails. If it is not, it will not respond, but generally when unlocking, the response distance is within 30 meters. If it exceeds this distance or is blocked by an object, the vehicle will not be able to execute the command issued by the car key.
[0003] With the establishment of super-large underground parking lots and the complexity of the parking lot structure, many car owners are not familiar with the local environment where they park their vehicles when they travel. Difficult to find a car

Embodiment Construction
[0022] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below in conjunction with the accompanying drawings and specific embodiments. For the sake of simplicity, some technical features known to those skilled in the art are omitted from the following description.
[0023] See details figure 1 , a method for finding a vehicle position at a long distance, comprising the following steps:
[0024] S1. The user activates the vehicle search function by entering a password on the handheld terminal, and sends a vehicle search request;
[0025] The hand-held terminal in this step can be a terminal with a car key as its main body. By entering a password, it can open its function of finding a vehicle, and send a search request to the corresponding vehicle;
[0026] S2. After receiving the vehicle search request, the receiving terminal in the car wakes up the alarm system in th...

The invention discloses a method for finding a vehicle's position from a distance. The method includes the following steps: transmitting a vehicle finding request through a hand-held terminal, the vehicle making a response by transmitting the vehicle's position information to the hand-held terminal, and when the distance between the hand-held terminal and the vehicle is smaller than a set value, the vehicle going beep or flashing. According to the invention, the method can position the vehicle's position through the hand-held terminal 30 meters away from the vehicle, and an alarm system in thevehicle can send alarm signals which can help the vehicle owner to rapidly position the vehicle, which can greatly save the time in finding the vehicle in places such as a super-large parking lot orparking lots that have complex crossings; when the vehicle owner forgets the vehicle's parking position, the method can position the map information of the vehicle and help the vehicle owner to shorten physical range.
Description
technical field [0001] The invention relates to a vehicle safety control system, in particular to a method for finding the position of a vehicle in a long distance. Background technique [0002] With the improvement of living standards, the number of cars has increased significantly. At present, the way to remotely lock the car door is that the infrared waves emitted by the car key have a fixed frequency and band. When the receiver in the car receives these waves, it will Screen it to make sure it is this wave frequency, and then extract and compare the data in the wave frequency. If the comparison is successful, the controller will issue a series of instructions to unlock and lock the door. Otherwise, the comparison fails. If it is not, it will not respond, but generally when unlocking, the response distance is within 30 meters. If it exceeds this distance or is blocked by an object, the vehicle will not be able to execute the command issued by the car key. [0003] With t...
