The embodiments of this application will now be described with reference to the accompanying drawings.

[0039] like Figure 1 The diagram shows a flowchart of a method for determining vehicle road conditions according to an embodiment of the present invention. The method includes:

[0040] Step 101: Obtain the total distance traveled by the vehicle to be judged during the entire journey;

[0041] Step 102: Obtain the proportion of the driving distance in the total driving distance that is at high speed, where the driving distance is the driving distance at a speed higher than a preset high speed threshold.

[0042] Step 103: Determine the road conditions of the vehicle to be judged based on the relationship between the proportion of high-speed driving and the preset high-speed driving proportion threshold.

[0043] In this embodiment of the invention, during a complete long-distance journey, the vehicle's journey typically involves a cycle of driving for a period, stopping for a period, and driving for a period... The stopped state of the vehicle cannot be used to determine the road conditions. Therefore, it is necessary to obtain the distance traveled by the vehicle during the complete journey, obtain the speed during that journey, set the speed exceeding a preset high-speed threshold as high-speed driving, obtain the proportion of high-speed driving in the entire journey, compare this proportion with a preset high-speed journey proportion threshold, and determine the road conditions of the vehicle based on the comparison result.

[0044] The high-speed threshold and the high-speed travel ratio threshold can be set according to actual usage needs, and this application does not limit their specific values. Preferably, the high-speed threshold is 80 km / h, and the high-speed travel ratio threshold is 80%.

[0046] If the proportion of the journey at high speed is higher than a preset high speed journey proportion threshold, the road condition of the vehicle to be judged is judged as a high speed road condition. If the proportion of the journey at high speed is lower than the preset high speed journey proportion threshold, the road condition of the vehicle to be judged is judged as a national highway and / or a provincial highway.

[0047] This invention provides an embodiment of the system that obtains the total distance traveled by a vehicle during a complete journey; obtains the proportion of this distance traveled at high speed, where the high-speed travel is defined as the distance traveled at a speed exceeding a preset high-speed threshold; and determines the road conditions of the vehicle based on the relationship between the proportion of high-speed travel and the preset high-speed travel proportion threshold. This allows the system to quickly and accurately obtain road condition information during the vehicle's journey.

[0048] like Figure 2 The diagram shows a flowchart of a method for determining vehicle road conditions according to another embodiment of the present invention. The step of obtaining the total distance traveled by the vehicle to be determined during a complete journey includes:

[0050] Step 202, obtain each segment - The distance traveled within the time period, the The time point at which the on signal is received for the nth time is described. This refers to the time point when the off signal is received for the nth time.

[0051] Step 203: Add up each segment of the journey to obtain the total journey distance. Where D represents the total distance traveled.

[0052] In this embodiment of the invention, the "on" position represents the position where the car provides power to the electronic devices inside the vehicle, and the "off" position represents the position where the car stops providing power. When the car receives the "on" signal, it means that the car is ready to start, and when the car receives the "off" signal, it means that the car is ready to stop. Therefore, a complete "receiving the on signal - receiving the off signal" can be represented as the vehicle completing a journey. By mapping the nth "on" signal to the nth "off" signal, the nth journey distance of the vehicle can be obtained. By adding up each journey distance, the total journey distance of the vehicle in the complete journey can be obtained.

[0053] like Figure 3 The diagram shown is a structural diagram of a system for determining vehicle road conditions according to an embodiment of the present invention. The system includes:

[0054] The total driving distance acquisition module 301 is used to acquire all driving distances of the vehicle to be judged during the complete journey.

[0055] The high-speed driving ratio acquisition module 302 is used to acquire the proportion of the driving distance in the driving distance that is driven at high speed, wherein the driving distance is the driving distance where the vehicle speed is higher than a preset high-speed threshold.

[0056] The judgment module 303 is used to judge the road conditions of the vehicle to be judged based on the relationship between the proportion of the high-speed driving distance and the preset high-speed driving distance proportion threshold.

[0057] In this embodiment of the invention, during a complete long-distance journey, the vehicle's journey typically involves a cycle of driving for a period, stopping for a period, and driving for a period... The stopped state of the vehicle cannot be used to determine the road conditions. Therefore, it is necessary to obtain the distance traveled by the vehicle during the complete journey, obtain the speed during that journey, set the speed exceeding a preset high-speed threshold as high-speed driving, obtain the proportion of high-speed driving in the entire journey, compare this proportion with a preset high-speed journey proportion threshold, and determine the road conditions of the vehicle based on the comparison result.

[0058] The high-speed threshold and the high-speed travel ratio threshold can be set according to actual usage needs, and this application does not limit their specific values. Preferably, the high-speed threshold is 80 km / h, and the high-speed travel ratio threshold is 80%.

[0059] The step of determining the road conditions of the vehicle to be judged based on the relationship between the proportion of high-speed travel and a preset high-speed travel proportion threshold includes:

[0060] If the proportion of the journey at high speed is higher than a preset high speed journey proportion threshold, the road condition of the vehicle to be judged is judged as a high speed road condition. If the proportion of the journey at high speed is lower than the preset high speed journey proportion threshold, the road condition of the vehicle to be judged is judged as a national highway and / or a provincial highway.

[0061] This invention provides an embodiment of the system that obtains the total distance traveled by a vehicle during a complete journey; obtains the proportion of this distance traveled at high speed, where the high-speed travel is defined as the distance traveled at a speed exceeding a preset high-speed threshold; and determines the road conditions of the vehicle based on the relationship between the proportion of high-speed travel and the preset high-speed travel proportion threshold.

This refers to the time point when the off signal is received for the nth time.

[0065] The total travel distance acquisition unit 403 is used to add up each segment of travel distance to obtain the total travel distance. Where D represents the total distance traveled.

[0066] In this embodiment of the invention, the "on" position represents the position where the car provides power to the electronic devices inside the vehicle, and the "off" position represents the position where the car stops providing power. When the car receives the "on" signal, it means that the car is ready to start, and when the car receives the "off" signal, it means that the car is ready to stop. Therefore, a complete "receiving the on signal - receiving the off signal" can be represented as the vehicle completing a journey. By mapping the nth "on" signal to the nth "off" signal, the nth journey distance of the vehicle can be obtained. By adding up each journey distance, the total journey distance of the vehicle in the complete journey can be obtained.
