The embodiments described below with reference to the accompanying drawings are illustrative and intended to explain the present application and should not be construed as limiting the present application.

A guidance route planning method and apparatus for a vehicle according to an embodiment of the present application will be described below with reference to the drawings. In the method, a current position of a vehicle is obtained by receiving a parking lot map corresponding to a vehicle target point and visually displaying the parking lot map, so that an optimal entrance of a target parking lot is searched, a first optimal path of the current position running to the parking lot and a second optimal path of the current position running to a target point at the optimal entrance are generated, and a visual guidance planning path is generated, so that the guidance process of the user is simpler and more convenient, the accuracy and reliability of vehicle guidance are improved, the intelligence of the vehicle is further improved, and the use experience of the user is improved. Therefore, the technical problems that in the related art, when a parking route is planned, due to the fact that the parking lot parking space information is insufficient, targeted route planning cannot be achieved, the navigation requirement of a user during parking cannot be met, and the user use experience is influenced are solved.

Specifically, fig. 1 is a schematic flowchart of a method for planning a guidance route of a vehicle according to an embodiment of the present disclosure.

As shown in fig. 1, the method for planning a guidance route of a vehicle includes the steps of:

in step S101, a map request is generated from a parking lot corresponding to a vehicle target point of the vehicle, and the map request is transmitted to the server.

It can be understood that, in the embodiment of the present application, the server may include a car-associated internet terminal T-box (vehicle-mounted wireless gateway), and the car-associated internet terminal may receive a parking lot map request corresponding to a vehicle target point, for example, a place identifier of a position where the target point is located may be included in the map request, and a corresponding parking lot high-precision map may be downloaded from a cloud terminal through a networking function based on the place identifier, and the high-precision map may inform a vehicle of refined parking lot internal information, including information such as high-precision coordinates, accurate parking places, channels, columns, signboards, and ground lines in the parking lot.

For example, a user selects a shop first of a building, a vehicle identifies a place identifier corresponding to the position of a parking lot according to the position of the parking lot corresponding to the building where the shop first is located, a parking lot map with the place identifier selectable is displayed for the user, the user can select a required map through human-computer interaction of a vehicle machine or a human-computer interaction interface of a mobile phone, a map request selected by the user is sent to a server, and the server downloads the map from a cloud side to a local vehicle end.

According to the method and the device, the map request can be generated according to the parking lot corresponding to the vehicle target point of the vehicle, and the map request is sent to the server, so that specific requirements of a user are known, necessary map data are provided for next parking lot path planning, the problem that the path planning of the user parking lot is not targeted enough pain points is solved, and the intelligent level of the vehicle is improved.

In step S102, the receiving server obtains the current location of the vehicle while controlling the vehicle to visually display the actual parking lot map sent based on the map request.

It can be understood that in the embodiment of the application, the high-precision map data is displayed in a visualized manner, the actual geographic situation is presented to the user in the form of a virtual image, the virtual image includes road elements such as lane lines, steering information and a lane topological structure, and the data with regional characteristics or the data analysis result is presented on the image of the virtual map.

In some embodiments, after the vehicle end acquires the high-precision map of the parking lot, the vehicle end displays the map picture of the parking lot on the vehicle machine, displays key lane information in the parking lot, such as an elevator entrance, a stair entrance, a building entrance and the like, and simultaneously acquires the current position of the vehicle, such as a vehicle-mounted GPS and the like, by using the vehicle-mounted positioning terminal.

According to the embodiment of the application, the actual parking lot map sent by the server based on the map request can be received, the vehicle is controlled to visually display the actual parking lot map, and meanwhile, the current position of the vehicle is obtained, so that geographic data can be visually presented to a user, and the driving process of the user is simplified.

Optionally, in an embodiment of the present application, the controlling the vehicle to visually display the actual parking lot map includes: identifying a plurality of vehicle owner interest target points in an actual parking lot map; and selecting a parking point corresponding to the vehicle target point from the target points interested by the plurality of vehicle owners.

Specifically, the interested target points of a plurality of vehicle owners are parking lot entrances and exits, such as elevator entrances, stair entrances, building entrances and the like, and the parking points corresponding to the vehicle target points are parking spaces which are located at the vehicle target points and have the closest horizontal distance. For example, the vehicle target point is A301 room, the visual map indicates a plurality of elevator mouths and stair mouths close to A room for the user, and the parking space closest to the A301 room in horizontal distance is selected in the parking lot, so that the user is helped to select the optimal parking position reaching the required target point, and the parking experience of the user is optimized.

In step S103, an optimal entrance of the target parking lot is searched based on the current position, a first optimal path for driving to the parking lot from the current position and a second optimal path for driving to the target point from the optimal entrance are generated, a guidance planning route is generated according to the first optimal path and the second optimal path, and the guidance planning route is visually displayed.

In some embodiments, the optimal entrance of the target parking lot can be searched based on the current position, a first optimal path from the current position to the parking lot and a second optimal path from the optimal entrance to the target point are generated, a visual guidance planning route is generated, an optimal route scheme for reaching the target point and completing parking is provided for a user, and the parking convenience of the parking lot of the user is improved.

For example, as shown in fig. 2, for a parking lot route planning schematic diagram in the embodiment of the present application, a vehicle may present a first optimal path and a second optimal path that are planned on a visual map, the visual map shows road information of a road where the vehicle is to travel and parking space distribution of the parking lot, the visual map may be projected on a vehicle-mounted screen terminal or a mobile phone terminal, or may be broadcast in real time on the route by combining a voice terminal in the vehicle.

In a practical implementation, the first optimal path may be generated by using a euclidean distance calculation method, i.e. for each pixel, determining the distance to each source pixel by calculating the hypotenuse using the two edges of the triangle, where the source is the identification of the location of the well, shopping center, road, forest stand, etc.

For example, according to the current position coordinates of the vehicle, the natural distance between the current position and each entrance of the parking lot is calculated by using an Euclidean distance calculation method, and the intersection with the shortest Euclidean distance is determined as the optimal entrance of the parking lot by comparing the distances, so that the current position and the optimal route of the target parking lot are obtained, the time required by a user to enter the parking lot is shortened, and the interaction inductance of the vehicle is improved.

Optionally, in an embodiment of the present application, generating a first optimal path for driving to the parking lot at the current location and a second optimal path for driving to the target point at the optimal entrance includes: and generating a second optimal path based on the optimal entrance, the parking point and the actual parking lot map.

As a possible implementation manner, the second optimal path may apply a shortest path algorithm, where the shortest path algorithm is used to calculate a shortest path from one node to another node, and the shortest path is calculated and obtained by the algorithm method, so as to obtain the second optimal path from the optimal entry to the target point.

For example, according to the optimal entrance of the parking lot and the target point selected by the car owner, the vehicle calculates the route along the connecting lane by applying the successive topological connectivity relation of the lanes in the high-precision map data, obtains the shortest route through the shortest route algorithm calculation, and combines the shortest route with the actual parking lot map to obtain a second optimal route, so that the step of planning the parking route by the user is simplified, and the time of the user is saved.

Optionally, in an embodiment of the present application, after visually displaying the guidance planning route, the method further includes: detecting whether the vehicle meets a preset replanning condition or not; and generating a new guidance planning route which is driven to the elevator port or the stair port with the distance meeting the preset condition and then returns to the parking point by bypassing according to the generated new guidance planning route from the parking point.

It can be understood that, in the embodiment of the present application, when the vehicle meets the preset re-planning condition, the vehicle end triggers re-route calculation to plan a route from the target point to the first and second near-elevator exits/stairways and then to detour back to the target point.

In the actual execution process, if the vehicle meets the preset re-planning condition, re-route calculation can be carried out through the vehicle-machine interactive interface, the newly-planned route focuses on finding vacant parking spaces by the tour assistant vehicle owner, the target point selected by the vehicle owner is used as the starting point and the target point of route planning, the other elevator mouths, the stair mouths, the property points and the like which are the first and the second nearest to the target point in the Euclidean distance are added, the shortest and non-repeated route calculation is carried out, and the route is used as a supplementary recommended route to be provided for the user, so that the parking of the user is guaranteed to be completed smoothly, and the use requirements of the user are met.

Optionally, in an embodiment of the present application, the preset re-planning condition is that the vehicle travels to a parking spot and does not complete parking.

It can be understood that, the embodiment of the application can detect whether the car owner completes the parking action on the shortest route, if the car owner can use the radar, the camera and the driver detection system to judge, the user can also manually confirm whether the parking is finished on the screen or the mobile phone end in the car through the man-machine interaction interface, and if the car is judged to be driven to the parking spot and the parking is not finished, the car triggers to calculate the route again, so that the user is helped to find the parking spot, and the use experience of the car is improved.

It should be noted that the preset reprogramming condition is set by a person skilled in the art according to actual situations, and is not specifically limited herein.

Optionally, in an embodiment of the present application, after generating the new guidance plan route, the method further includes: and recommending available parking spaces along the new guidance planning route to the user according to the parking information of the parking lot.

It can be understood that, in the embodiment of the present application, after the new guidance planning route is generated, the vehicle recommends available parking spaces along the new guidance planning route to the user according to the parking information of the parking lot, for example, the remaining parking spaces around can be shown to the user through the information of the available parking spaces provided by the parking lot end, so that the process of finding the parking spaces by the user is simplified, and the degree of automation of the vehicle is improved.

The working contents of the embodiment of the present application are explained in detail below with a specific embodiment as shown in fig. 3.

Step S301: the car owner selects the high-precision map of the parking lot.

Namely, the corresponding high-precision parking lot map data is acquired from the cloud end according to the selection of the vehicle owner, and the selectable parking lot map is provided for the vehicle owner through a human-computer interaction interface of the vehicle machine or a human-computer interaction interface of the mobile phone end.

Step S302: and issuing a high-precision map of the parking lot to the vehicle end by the cloud end.

That is to say, after the car owner selects, download the data from the high in the clouds to the car end, because of the country parking sea distributes a large amount, can't all satisfy the demand of car end local storage, download from the high in the clouds and can the pertinence provide data, avoid invalid storage.

Step S303: and visualizing a vehicle end parking lot map.

That is, after the vehicle end acquires the parking lot map data, the vehicle end renders and displays lanes of the parking lot data and points of interest of the user, and after the vehicle end acquires the data issued from the cloud, the vehicle end needs to perform data analysis according to the parking lot map specification, and display the parking lot data to the vehicle owner in a visual image form.

Step S304: the vehicle owner selects the target point.

Namely, the visual image of the parking lot clearly marks the target points of interest of car owners such as elevator entrances, elevator exits and property points in the parking lot, so that the user can conveniently complete the interface selection.

Step S305: and recommending the entrance of the parking lot and calculating the shortest route.

That is, according to the position of the current vehicle, combining with a high-precision map of the parking lot, and applying an euclidean distance calculation method, the natural distances from the coordinates of the position of the current vehicle to the entrances of the parking lots are calculated respectively. And after calculation, recommending the owner to go to the nearest parking lot entrance according to the length comparison. Secondly, route calculation is carried out along the connecting lane according to the recommended entrance of the parking lot and a target point selected by the vehicle owner. The parking lot high-precision map has a topological connection relation between a lane and a front-rear relay between the lanes, and a vehicle end calculates and obtains the shortest route by applying a shortest path algorithm according to the connection relation of the lanes, so that an automobile owner can select an empty parking space in the route to park according to the requirement in the process of driving to a target point.

Step S306: and judging whether the vehicle owner finishes parking, if so, ending the process, and otherwise, executing the step S307.

That is, it is determined whether the car owner completes the parking operation on the shortest route, if so, the parking lot route planning process may be ended, and if not, the route re-calculation is triggered to plan the recommended route of the joining route point.

Step S307: calculating a recommended route for the joining route point.

That is, if the owner does not finish parking in the recommended shortest planned route, the vehicle end can trigger re-route calculation through the vehicle-machine interactive interface, and the route which bypasses the target point after driving from the target point to the first and second near-elevator/stairway openings is planned. And the route calculation again mainly aims at finding vacant parking spaces by the tour assistant vehicle owner, takes a target point selected by the vehicle owner as a starting point and a target point of route planning, adds other elevator ports, stair ports, property points and the like which are the first and the second nearest in the Euclidean distance from the target point, calculates the shortest and unrepeated route, and provides the shortest and unrepeated route as a supplementary recommended route for the user.

According to the method for planning the guiding route of the vehicle, the current position of the vehicle is obtained by receiving the parking lot map corresponding to the vehicle target point and visually displaying the parking lot map, so that the optimal entrance of the target parking lot is searched, the first optimal path of the current position driving to the parking lot and the second optimal path of the current position driving to the target point through the optimal entrance are generated, and the visual guiding planning route is generated, so that the parking process of a user is more convenient, the intelligence of the vehicle is improved, and the use experience of the user is improved. Therefore, the technical problems that in the related art, when a parking route is planned, parking lot parking space information is insufficient, targeted route planning cannot be achieved, the navigation requirement of a user when the user parks the vehicle cannot be met, and user use experience is influenced are solved.
