The present application will be described in detail with reference to specific examples.
Referring to fig. 2, fig. 2 is a schematic flowchart of a road height limit prompting method provided in an embodiment of the present application, where the method is applied to the intelligent vehicle-mounted terminal shown in fig. 1, and the method includes the following steps:
s201, acquiring a first height and a first path of the vehicle.
In the actual driving process, a driver or other persons can plan a path through a navigation application on the intelligent vehicle-mounted terminal before or during driving, before the path is planned, the driver or other persons input destination information, and a navigation path from the current position to the destination is planned according to the input destination.
It should be noted that one or more than two alternative navigation paths may be planned according to the input destination, and the driver may select one path from the alternative navigation paths as the driving path of the vehicle according to features, including but not limited to: avoiding congestion, avoiding charging, having shortest time and shortest distance, not walking at high speed, having high speed priority and the like.
The intelligent vehicle-mounted terminal obtains a driving path selected by a driver or other people in the navigation application as a first path of the vehicle.
Further, in order to obtain the height of the vehicle, when a driver or other persons accurately know the height of the vehicle, the height of the vehicle may be directly input on the intelligent vehicle-mounted terminal, if the driver or other persons cannot accurately know the height of the vehicle, the vehicle type, the vehicle brand and the specific vehicle type number of the vehicle may be input on the intelligent vehicle-mounted terminal, the intelligent vehicle-mounted terminal may send a network request to the server to obtain the vehicle height corresponding to the vehicle type, the vehicle brand and the specific vehicle type, and the intelligent vehicle-mounted terminal takes the vehicle height as the first height. In some possible examples, the vehicle may be loaded with an object and the loaded object exceeds the height of the roof, and the actual height of the vehicle acquired by the intelligent vehicle-mounted terminal may not be the actual height of the vehicle during driving, so that the intelligent vehicle-mounted terminal may periodically request to acquire an updated height of the vehicle during driving through the network.
It should be noted that a laser distance measuring head may be disposed on the speed limit frame, the laser distance measuring head is connected to the background computer and the server, respectively, when the vehicle passes through the height limit intersection, the laser distance measuring head measures the distance between the vehicle and the height limit frame in real time, and transmits the recorded data to the background computer and the server, and the intelligent vehicle-mounted terminal may obtain the first height of the vehicle by sending a network request value to the server.
S202, sending the altitude request message of the first path to a network side.
After acquiring the first height and the first path of the vehicle, the intelligent vehicle-mounted terminal also needs to acquire the minimum height of all height-limiting areas in the first path, so that the intelligent vehicle-mounted terminal can send a height request message to a server or a cloud storage or a rear-end platform to acquire the minimum height of all height-limiting areas in the first path.
S203, receiving an altitude request response issued by a network side, wherein the altitude request response comprises the lowest limit altitude of the first path and a first coordinate of the lowest limit altitude.
After receiving the height request message of the first path, the server or the cloud storage or the back-end platform searches for the height-limited area existing in the first path and the height-limited height corresponding to the height-limited area, the acquisition of the height-limited height may be stored in the server for navigation application, and the acquisition of the height-limited height may include manual addition and networking real-time update, or may be data obtained by a vehicle front camera in cooperation with an intelligent identification device or data recognized by means of a more complex image of a cloud server. And comparing the height limiting heights of the height limiting areas in the first path one by one, selecting the lowest height limiting height and the height limiting area corresponding to the lowest height limiting height, packaging the height request response containing the lowest height limiting height and the coordinates of the height limiting area corresponding to the lowest height limiting height, and sending the height request response to the intelligent vehicle-mounted terminal. And after receiving the height request response, the intelligent vehicle-mounted terminal unpacks the height request response to obtain the minimum height of the first path and a first coordinate of the minimum height.
S204, calculating a difference value between the minimum limit height and the first height, if the difference value is larger than a set threshold value, displaying the first path, and if the difference value is smaller than or equal to the set threshold value, generating a second path, wherein the minimum limit height of the second path is higher than the first height.
Specifically, after the intelligent vehicle-mounted terminal obtains the minimum height and the first coordinate of the minimum height of the first path, the dangerous condition of the first path where the vehicle runs is judged by calculating the difference between the minimum height and the first height. When the difference value is larger than the preset threshold value, the intelligent vehicle-mounted terminal displays the first path and prompts the first path to avoid collision with the height limiting frame caused by people standing out of a skylight or loosening of a vehicle top load, and when the difference value is larger than the preset threshold value and far larger than the preset threshold value, the intelligent vehicle-mounted terminal displays the first path but does not prompt the first path; when the difference value is larger than the preset threshold value, the first path is prompted to be forbidden to pass, the second path is planned again, and if the driver does not pay attention to the first path and continues to drive, the intelligent vehicle-mounted terminal can conduct emergency treatment, so that the safety of people and vehicles is guaranteed.
For example, when the height limit frame is higher than the vehicle height by 10cm and not higher than 50cm, the intelligent vehicle-mounted terminal displays the selected running path, and carries out voice prompt when the vehicle is 100m away from the first coordinate, for example, the voice prompt can be 'a height limit mark at the position 100m in front, please slow down and do not extend out of the window'; when the height limiting frame is far higher than the height of the vehicle by 50cm, such as 100cm, the intelligent vehicle-mounted terminal only displays the selected running path; when the height-limiting frame is lower than the height of the vehicle by 10cm, the intelligent vehicle-mounted terminal prompts the running path to be forbidden to pass through in a voice mode, for example, the voice prompt can be 'the path is forbidden to pass through and a path is planned again for you', when a driver does not notice the voice prompt to continue running, the intelligent vehicle-mounted terminal can calculate the time when the vehicle reaches the height-limiting area with the lowest height limit by acquiring the current running position, the current speed and the height-limiting area corresponding to the lowest height limit of the vehicle, the intelligent vehicle-mounted terminal can remind the driver by giving an alarm within the time, and can also send a message to a vehicle control system to inform the vehicle control system of controlling the motion state of the vehicle, and the vehicle control system is linked with a vehicle body power bus to control the vehicle to slow down until.
Further, the set threshold may be set by the intelligent vehicle-mounted terminal according to an actual application scenario, or may be an optimal value obtained by analyzing the network data by the intelligent vehicle-mounted terminal, which is not limited herein.
Optionally, the generating the second path specifically includes: and acquiring a link identification containing the first coordinate, deleting the link identification from the navigation path database, identifying a first identity of a vehicle driver, acquiring a user portrait corresponding to the first identity, and acquiring w navigation paths from the navigation database according to the user portrait, wherein the w navigation paths are composed of a plurality of links in the navigation path database, and w is a positive integer greater than or equal to 1.
Wherein, the first identity of the vehicle driver specifically comprises: the method comprises the steps of collecting a first picture of a vehicle driver, generating input data according to the first picture, inputting the input data into a face recognition model, carrying out forward operation to obtain a forward operation result, comparing the forward operation result with a preset template result, determining a first preset template result closest to the forward operation result, and determining that an identity corresponding to the first preset template result is a first identity.
Wherein, the obtaining a plurality of navigation paths from the navigation database according to the user profile specifically comprises: and extracting w features related to the navigation path from the user portrait, generating a plurality of navigation paths, and sequencing the plurality of navigation paths according to each feature in the w features to obtain w navigation paths.
It can be understood that, in the actual operation process, when the first path is prohibited from passing and the second path needs to be regenerated, in order to recommend the second path more meeting the needs of the driver to the driver user and not require further operation of the driver, so that the driver is more focused in the driving process, the intelligent vehicle-mounted terminal can identify the identity information of the driver of the vehicle, acquire the characteristics of the driver and the historical navigation data, and generate the second path more meeting the needs of the driver according to the characteristics and the historical navigation data.
It should be noted that the characteristics and the historical navigation data of the driver may also be obtained by logging in the user name or the account of the driver, or may be obtained by recognizing the voice of the driver through the voice of the intelligent vehicle-mounted terminal, which is not limited in this application.
It can be seen that the method for prompting height limit of a road described in the embodiment of the present application is applied to an intelligent vehicle-mounted terminal, where the intelligent vehicle-mounted terminal sends a height request message of a first path to a network side by obtaining a first height and the first path of a vehicle, receives a height request response issued by the network side, calculates a difference between a minimum height limit and the first height, and if the difference is greater than a set threshold, displays the first path, and if the difference is less than or equal to the set threshold, generates a second path, so that a driver can be effectively prompted in a height limit area in time, and when the first height of the vehicle exceeds the minimum height limit of the first path, a driving path is changed, and occurrence of traffic accidents is reduced.
Referring to fig. 3, in keeping with the embodiment shown in fig. 2, fig. 3 is a schematic flowchart of another road height limit prompting method provided in the embodiment of the present application, and as shown in fig. 3, the method is applied to an intelligent vehicle-mounted terminal, and the method includes:

Wherein n is a positive integer greater than or equal to 1.
The acquisition of the bridge road section can be stored in a server of a navigation application, the acquisition of the bridge road section can comprise manual addition and networking real-time update, and also can be data obtained by matching a front camera of a vehicle with an intelligent identification device or data identified by means of a more complex image of a cloud server, and the embodiment of the application is not limited to the data.

And S307, receiving n weight limit values of the n bridge sections.
After receiving the weight limit request message, the server or the cloud storage or the back-end platform searches for weight limit values corresponding to the identifiers of the n bridge sections in the first path, and then encapsulates weight limit request responses containing the n weight limit values of the n bridge sections and sends the weight limit request responses to the intelligent vehicle-mounted terminal. And after receiving the weight limit request response, the intelligent vehicle-mounted terminal unpacks the weight limit request response to obtain weight limit values corresponding to the identifiers of the n bridge road sections in the first path.
S308, obtaining a minimum weight limit value from the n weight limit values, calculating a weight difference value between the minimum weight limit value and the vehicle weight, if the weight difference value is larger than a weight threshold value, determining the navigation path as the first path, and if the weight difference value is smaller than the weight threshold value, regenerating a new navigation path.
Specifically, after the intelligent vehicle-mounted terminal obtains n weight limit values of the first path, the minimum weight limit value is obtained from the n weight limit values, and the dangerous condition of the vehicle running on the first path is judged by calculating the difference value between the minimum weight limit value and the current vehicle weight. When the difference value is larger than the preset threshold value, the intelligent vehicle-mounted terminal determines that the navigation path of the vehicle is the first path and prompts, and when the difference value is larger than the preset threshold value and is far larger than the preset threshold value, the intelligent vehicle-mounted terminal displays the first path but does not prompt; when the difference value is larger than the preset threshold value, the first path is prompted to be forbidden to pass, a new path is planned again, and if the driver does not pay attention to the first path and continues to drive, the intelligent vehicle-mounted terminal can perform emergency treatment, so that the safety of people and vehicles is guaranteed.
