Apply in embodiment, the based reminding method that drives with caution is applied to above-mentioned driving adjusting device 10.Below to shown in Fig. 2 careful
The detailed process and step of careful assisting automobile driver method are described in detail.
Step S210 obtains vehicle current steering position, drive route and surrounding enviroment information in real time.
In the present embodiment, vehicle can be acquired to obtain corresponding week by way of installing different types of sensor
Surrounding environment information determines the vehicle based on GPS (Global Positioning System, global positioning system) system
Position obtains corresponding steering position, and carries out driving navigation to vehicle based on map navigation system and obtain corresponding drive route.
It is described to drive what adjusting device 10 be installed from the vehicle when the driving adjusting device 10 is mounted on the vehicle
The current steering position of the vehicle, drive route and surrounding enviroment information are directly obtained at onboard system in real time；It is driven when described
When to sail adjusting device 10 be weather server or individual electronic equipment, the drivings adjusting device 10 can be based on network from described
The current steering position of the vehicle, drive route and surrounding enviroment information are obtained at the onboard system installed on vehicle in real time.
Step S220, according to the current steering position and the drive route, from weather server described in acquisition
On drive route using the steering position as the meteorological data in the pre-determined distance section of starting point.
In the present embodiment, if the driving adjusting device 10 is mounted on the vehicle, the driving adjusting device
10 can include the current steering position of the vehicle, drive route and surrounding enviroment information by sending to the weather server
Information of vehicles searches being in for Corresponding matching based on the information of vehicles by the weather server in the meteorological data of storage
On the drive route using the steering position as the meteorological data in the pre-determined distance section of starting point, and meteorological taken by described
The meteorological data found is sent to the mode for driving adjusting device 10 by business device, or is sent out to the weather server
Image data acquisition instruction supply gas to obtain all meteorological datas stored at the weather server, and in all gas got
The mode that image data is searched, obtain on the drive route using the steering position as in the pre-determined distance section of starting point
Meteorological data.
If the driving adjusting device 10 is weather server, the driving adjusting device 10 is obtained at the vehicle
After getting the current information of vehicles of the vehicle, the steering position in the information of vehicles included and drive route will be directly based upon certainly
Row ground searched in all meteorological datas of storage, using obtain on the drive route using the steering position as starting point
Pre-determined distance section in meteorological data.
If the adjusting device 10 that drives is the electronics individually communicated to connect with the vehicle and the weather server
Equipment, then the driving adjusting device 10 can be described to obtain by sending meteorological data acquisition instruction to the weather server
All meteorological datas stored at weather server, and the mode searched in all meteorological datas got, or to institute
It states weather server and sends the current information of vehicles of the vehicle got, the information of vehicles is based on by the weather server
Searched in the meteorological data of storage Corresponding matching on the drive route using the steering position as the pre- of starting point
If the meteorological data in section, and the meteorological data found is sent to the driving by the weather server
The mode of adjusting device 10, obtain on the drive route using the steering position as the gas in the pre-determined distance section of starting point
Image data.
Step S230 calculates the data reliability of the meteorological data according to the surrounding enviroment information got.
In the present embodiment, when the driving adjusting device 10 obtain be with the steering position on the drive route
After meteorological data in the pre-determined distance section of starting point, the driving adjusting device 10 will be current based on the vehicle got
Surrounding enviroment information calculate the data reliability of the meteorological data, with judge the meteorological data whether with the current institute of the vehicle
Practical Meteorological Requirements situation in position is consistent.Wherein, the surrounding enviroment information that the basis is got calculates the meteorology number
According to data reliability the step of include:
It is extracted from the meteorological data got and the current matched target weather data of the steering position；
The target weather data and the surrounding enviroment information are subjected to comparing, and institute is calculated according to comparison result
The data similarity between target weather data and the surrounding enviroment information is stated, the corresponding data reliability is obtained.
Wherein, the driving adjusting device 10 can be by by target weather data and data type phase in surrounding enviroment information
The mode that same data are compared realizes the comparison between target weather data and surrounding enviroment information.For example, by target day
Wind data of the destiny in is compared with the wind-force information in surrounding enviroment information, and the illumination in target weather data is strong
Degree according to being compared with the illumination intensity information in surrounding enviroment information, by target weather data temperature data and periphery
Temperature information in environmental information is compared.The driving adjusting device 10 will be believed according to target weather data and surrounding enviroment
The data difference at different types of data is ceased, the data between the target weather data and the surrounding enviroment information are calculated
Similarity, and the data similarity to be calculated is as corresponding data reliability.Wherein, the data similarity
Numerical value is higher, then shows that the meteorological data got and the Practical Meteorological Requirements situation of the vehicle present position get over phase
Symbol.
The data reliability is compared by step S240 with default believability threshold, and not less than when according to working as
The preceding meteorological data judges in the pre-determined distance section with the presence or absence of bad weather.
In the present embodiment, when the data reliability being calculated is not less than the default believability threshold, table
The bright meteorological data got is consistent with the Practical Meteorological Requirements situation of the vehicle present position, the driving at this time
Adjusting device 10 by based on the drive route got using the steering position as in the pre-determined distance section of starting point
Meteorological data, judge on the drive route using the steering position as in the pre-determined distance section of starting point with the presence or absence of severe
Weather.Wherein the current meteorological data of the basis judges in the pre-determined distance section with the presence or absence of boisterous step
Suddenly include:
