Problems solved by technology

But such a solution still requires additional visual attention from the driver
[0004] Based on this, although there is currently a technical solution for prompting users based on predicting wrong behaviors of users, this technical solution may provide wrong prompts, thereby causing interference to users

Embodiment 1

[0053] The method of information prompt in this embodiment, such as figure 1 shown, including the following steps:

[0054] Step 101: Statistically calculate the first occurrence probability of wrong driving from the first road intersection to the second road intersection every day on average within the set time period;

[0055] Here, the first road intersection is the road intersection of the planned route when the deviation occurs; the second road intersection is the road intersection of the actual driving route when the deviation occurs.

[0056] The average daily occurrence probability from the first road intersection to the second road intersection in the statistical setting time period may specifically include:

[0057] Within the set time period, record the first relevant information related to wrong driving from the first road intersection to the second road intersection;

[0058] According to the recorded relevant information, count the third occurrence probability ...

Embodiment 2

[0089] On the basis of the first embodiment, this embodiment mainly describes how to eliminate the first relevant information corresponding to the wrong driving caused by temporary emergencies. like figure 2 As shown, the specific implementation of obtaining the second relevant information by excluding the first relevant information corresponding to the wrong driving caused by temporary emergencies may include the following steps:

[0090] Step 201: Calculate the average probability Pa and standard deviation S of all third occurrence probabilities;

[0091] Step 202: compare whether the third occurrence probability of each statistical period is greater than the value related to Pa and S, if yes, execute step 203, otherwise, execute step 204;

[0092] Here, the values ​​related to Pa and S can be set according to experience, for example: set to Pa+3S.

[0093] Step 203: removing the data corresponding to the statistical period of the third occurrence probability greater than...

Embodiment 3

[0101] On the basis of the first and second embodiments, this embodiment mainly describes the specific circumstances under which the user should be prompted. like image 3 As shown, the present embodiment determines the method for prompting the user, including the following steps:

[0102] Step 301: sort the second occurrence probability Pi of the users used from high to low;

[0103] Step 302: According to the sorting result, calculate the percentage ranking rate Ri of Pi;

[0104] Here, the percentage rank rate Ri indicates the ratio of user i's driving error rate to which percentage of users' driving error rate is lower.

[0105] Step 303: Judging whether Ri is less than the first occurrence probability P, if yes, execute step 304, otherwise, execute step 306;

[0106] Step 304: When judging whether the first occurrence probability P is greater than the second set value, if yes, execute step 305, otherwise, execute step 306;

[0107] Step 305: Output the judgment result...

Abstract

The invention discloses an information prompt method. The method includes the steps that the first occurrence probability that users drive wrongly to a second road intersection from a first intersection averagely every day in a set period of time is calculated; the second occurrence probability that each user drives wrongly to the second road intersection from the first intersection averagely every day in the set period of time is determined; when it is determined that users corresponding to the second occurrence probability need to be prompted according to the first occurrence probability and the second occurrence probability, the users corresponding to the second occurrence probability are prompted. The invention further discloses an information prompt device.

Description

technical field [0001] The invention relates to navigation technology, in particular to an information prompting method and device. Background technique [0002] With the development of maps and navigation technology, people can easily follow navigation instructions to reach their destination without too much preparation. However, urban traffic roads are becoming more and more complicated. Even with navigation services, there may still be a lot of situations in the process of driving. For example: on the viaduct, although the navigation system prompts "Turn right at ** meters ahead", but because the intersection is not conspicuous, you will miss it if you are negligent. [0003] In response to the problem of missing intersections during navigation, many navigation services provide real-scene zoom-in at complex intersections, 3D real-scene buildings, and even real-scene navigation, which can reproduce road conditions more realistically, and the driver can clearly see them at...
