[0002] At present, due to the rapid growth of automobiles, it has brought serious traffic congestion problems to the city. Many traffic accidents are caused by users not being able to turn on the corresponding coping functions of automobiles in time according to the current weather conditions, such as In snowy days, because the user does not open the wheel anti-skid device in time, it will cause brake failure, brake failure and other situations, resulting in serious traffic accidents
Moreover, the existing car positioning technology can only locate the position of its own car, but cannot obtain the position of the surrounding cars, let alone adjust the driving state of the car according to the density of the surrounding cars.

Embodiment 1
[0090] The terminal in this embodiment can be an intelligent terminal, a mobile intelligent terminal, or a vehicle-mounted intelligent terminal; when the terminal is a mobile intelligent terminal, it can include: a smart phone, a notebook, a PDA intelligent terminal and a tablet computer or an intelligent wearable device etc.; the wearable device can be any of smart glasses, smart bracelets, smart watches, smart necklaces, and smart helmets;
[0091] In addition, it should be pointed out that the connection between the car and the terminal can be connected through a connection line, such as a USB data line, etc.; it can also be connected through a wireless network, including: LAN, WAN or other networks; WAN includes: 3G network, 4G network, WCDMA , GSM; local area network includes: local area network connected by bluetooth, infrared, wifi or wired; it can also be connected by bluetooth or infrared; it can also be connected with the car by sound waves.

[0185] The determination process of vehicle density is as follows:
[0186] Step 201. Obtain the moving speed and moving direction of the terminal according to the terminal location information of nearby cars;
[0187] Step 202, judging whether the moving distance between the terminals within the set time range is less than the range of the vehicle, if so, go to step 023;
[0188] Step 203, determine whether the moving speeds of the above-mentioned terminals are the same within the set time range and the distance between them is less than 1.5 meters. remove;
[0189] Step 204, summarizing the screened terminals, the obtained data is valid terminals, counting the number and location information of valid terminals, and then obtaining the vehicle density.
[0190] Through the above technical solution, each terminal on the same vehicle is screened, and only one of each terminal is reserved, so as to improve the judgment accuracy. At the same time, it enables the detection and s...

Abstract
The invention discloses a method and system for adjusting the driving state of a car based on weather information, wherein the method for adjusting the driving state of a car according to the weather information includes: S1 establishing a connection between the terminal and the vehicle-mounted system of the main car; S2 obtaining the position information of the terminal through GPS and The car location information of nearby cars, and display the car density of nearby cars on the display screen of the terminal; S3 obtains local weather information through the terminal; S4 obtains the driving status information of the main car through the vehicle system, and sends the driving status information to Terminal; S5 terminal obtains matching driving information based on weather information, driving status information and vehicle density; S6 terminal sends matching driving information to the vehicle system. In this way, the terminal can combine weather information, driving status information and vehicle density to obtain matching driving information, and then the terminal sends the matching driving information to the vehicle system, so that the driving status of the main vehicle can be controlled through the vehicle system.
Description
technical field [0001] The invention relates to the technical field of vehicle control, in particular to a method and system for adjusting the driving state of a vehicle according to weather information. Background technique [0002] At present, due to the rapid growth of automobiles, it has brought serious traffic congestion problems to the city. Many traffic accidents are caused by users not being able to turn on the corresponding coping functions of automobiles in time according to the current weather conditions, such as In snowy days, because the user does not open the wheel anti-skid device in time, it will cause brake failure, brake failure and other situations, and cause serious traffic accidents. Moreover, the existing car positioning technology can only locate the position of its own car, but cannot obtain the positions of surrounding cars, let alone adjust the driving state of the car according to the density of surrounding cars. [0003] Therefore, how to activat...
