Optionally, as another embodiment of the present application, in S102 (obtaining the trajectory information of the vehicle according to the position information) in the present application, any one or more of the following two manners may be included, but not limited to:
the first mode is as follows:
and acquiring the track information of the vehicle in a second preset range according to the position information.
According to the method and the device, the track information of the vehicle in the second preset range can be acquired according to the current position information of the vehicle received in real time. The second preset range is not specifically limited, that is, the second preset range may be 2km, and the second preset range may also be 10 km. It should be noted that, in the present application, the first preset range may be the same as the second preset range, and the first preset range may also be different from the second preset range.
Alternatively, for example, when it is detected that the vehicle has traveled 5km according to the position information of the vehicle received in real time, the present application may acquire the track information of the vehicle within the 5 km. Further, the application can also only acquire the track information of any 2km of the vehicle within the 5km of the vehicle.
In another embodiment of the present application, the first presentation information is generated according to a preset strategy and track information within a second preset range.
In this application, all the parameter information within the second preset range may be detected according to a preset policy. Further, all the parameter information is screened according to preset conditions, and the parameter information meeting the conditions is used as first display information. For example, taking the parameter information as the gas station information as an example, when it is detected that the vehicle has traveled 5km from the starting point according to the position information of the vehicle received in real time, a range 2km away from the current position of the vehicle is selected as the second preset range from the 5km travel track. Further, all the gas station information within the 2km range is detected according to a pre-stored preset strategy, and all the gas station information is screened according to preset conditions. And finally, the gas station information meeting the preset conditions is used as first display information.
Further optionally, taking the parameter information as weather information for example, when it is detected that the vehicle has traveled 50km from the starting point according to the location information of the vehicle received in real time, and taking the travel track range of 50km as the second preset range. Further, weather information within the range of 50km is detected according to third-party weather software in a preset strategy, and when weather information different from the current position of the vehicle is detected to exist within the range of 50km, the weather information of the position is used as first display information.
In another embodiment of the present application, the time when the vehicle passes through the trajectory information within the second preset range is calculated.
And generating second display information according to the size relation between a preset time threshold and the time of the track information passing through the second preset range, wherein the preset time threshold is a time value of the vehicle passing through the second preset range generated according to a preset strategy.
Optionally, the time when the vehicle passes through the track information within the second preset range may be calculated. And comparing the time with a time value (preset time threshold) of the vehicle passing through a second preset range, which is generated according to a preset strategy, so as to generate second display information.
Taking the parameter information as the road condition information, the second preset range as 1km, and the calculated time for the vehicle to pass through the track information in the second preset range as 10 minutes as an example. I.e. the current vehicle has travelled 1km in 10 minutes. In the application, the preset strategy can be to calculate the time value required by the vehicle to pass through the road of 1km under the condition that the road is smooth. For example, when the calculated preset time threshold is 5 minutes under the condition that the road is smooth, the preset time threshold (5 minutes) is compared with the time (10 minutes) when the vehicle passes through the track information of 1km, so that the time when the vehicle passes through the track information in the second preset range is greater than the preset time threshold, and the second display information that the current road condition information is congested is generated. It should be noted that when the preset time threshold is greater than or equal to the time when the vehicle passes through the track information in the second preset range, the second display information that the current road condition information is smooth can be generated.
It should be noted that the preset strategy may also be to calculate a time value (preset time threshold) required for the vehicle to pass through the second preset range in the case of road congestion. And comparing the preset time threshold value with the time value of the track information of the vehicle passing through the second preset range. The specific implementation manner is the same as that described above, and is not described herein again.
In a preferred embodiment, the preset policy in the present application may also be a preset time threshold generated under the condition of the third-party navigation software. Specifically, the second preset range and other related information may be sent to the third-party navigation software, and the third-party navigation software calculates the preset time threshold. Further, the preset time threshold value is compared with the time value of the track information when the vehicle passes through the second preset range. The specific implementation manner is the same as that described above, and is not described herein again.
The second mode is as follows:
and acquiring the track information of the vehicle within a preset time range according to the position information.
According to the method and the device, the track information of the vehicle within the preset time range can be acquired according to the current position information of the vehicle received in real time. The preset time range is not specifically limited, that is, the preset time range may be 5 minutes, and the preset time range may also be 30 minutes.
Alternatively, for example, when it is detected that the vehicle has traveled for 60 minutes according to the position information of the vehicle received in real time, the present application may acquire the trajectory information of the vehicle during the travel for the 60 minutes. Further, the present application may also acquire only the trajectory information of any 10 minutes of the 60 minutes of the vehicle.
In still another embodiment of the present application, after acquiring the trajectory information of the vehicle in the preset time range according to the position information, the length of the trajectory information of the preset time range may be further calculated.
And generating third display information according to the size relation between a preset length threshold and the length of the track information within the preset time range, wherein the preset length threshold is a numerical value of the running length of the vehicle within the preset running time range, which is generated according to a preset strategy.
In the method and the device, the length of the track information of the vehicle passing through the preset time range can be calculated. And the length and the value of the running length of the vehicle in the running preset time range, which is generated according to the preset strategy, are compared. And (presetting a length threshold) carrying out size comparison, and further generating third display information.
Taking the parameter information as the road condition information, the preset time range is 10 minutes, and the length of the calculated track information in the preset time range for the vehicle to run is 1km as an example. I.e. the current vehicle has travelled 1km in 10 minutes. Further, in the present application, the preset strategy may be to calculate a length value (preset length threshold) of the vehicle running in 10 minutes under the condition that the road is clear. For example, when the calculated preset length threshold is 5km under the condition that the road is smooth, the preset length threshold (5km) is compared with the length (1km) of the track information of the current vehicle passing within the preset time range, so that the length of the track information passing within the preset time range is smaller than the preset length threshold, and therefore third display information that the current road condition information is congested is generated. It should be noted that, when the preset length threshold is greater than or equal to the length of the track information of the vehicle passing through the preset time range, the third display information that the current road condition information is smooth may be generated.
It should also be noted that the preset strategy may also be to calculate a value of the travel length of the vehicle in the travel preset time range (preset length threshold) in the case of road congestion. And comparing the preset length threshold value with the length value of the track information of the vehicle in the preset time range. The specific implementation manner is the same as that described above, and is not described herein again.
In another preferred embodiment, the preset policy in the present application may also be a preset length threshold generated under the condition of the third-party navigation software. Specifically, the preset time range and other related information may be sent to the third-party navigation software, and the preset length threshold may be calculated by the third-party navigation software. Further, the preset length threshold value is compared with the length value of the track information of the vehicle passing through the preset time range. The specific implementation manner is the same as that described above, and is not described herein again.
