Automobile headlight automatic adjustment control system

Abstract

This invention provides an automatic vehicle light adjustment control system, relating to the field of intelligent vehicle control technology. The system uses a server to obtain parking information sent by an intelligent terminal, updates the parking space status information in the garage based on the parking information, and then obtains a guidance request sent by the intelligent terminal. The system then obtains the user's real-time location, current parking space status information, and corresponding parking information. The system then selects a guidance vehicle from among all vehicles corresponding to occupied parking spaces. Finally, the system generates corresponding guidance light control requests based on all guidance vehicles and sends them sequentially to the guidance vehicles in the order of the sections along the optimal guidance path. Ultimately, the system controls the lights of vehicles parked in the underground garage to guide users to their parking locations, without the need for additional guidance hardware.

The specific determination steps are: when the parking direction is a first direction, the turn signal and headlights at the front of the vehicle are used as the guiding light control objects; when the parking direction is a second direction, the turn signal and taillights at the rear of the vehicle are used as the guiding light control objects.

[0059] In one embodiment, the guide light control request generating module further includes: a lighting sequence determining unit configured to determine a lighting sequence of the light control objects based on the directions of the road sections corresponding to the respective guide vehicles.

[0060] In one embodiment, the guide light control request generating module further includes: a target vehicle determining unit, configured to determine a target vehicle to which the guide light control request is to be sent; and specifically includes:

[0061] S3.3. Acquire all leading vehicles that have not been the target vehicle as candidate target vehicles, send a Bluetooth activation request to the candidate target vehicles, and send a Bluetooth ranging request to the smart terminal to obtain the Bluetooth ranging results between the smart terminal and all candidate target vehicles;

[0065] The guiding light control request includes a light control object, a lighting order of the light control object, and a preset light lighting duration.

[0066] The beneficial effects of this embodiment are:

[0067] The present invention obtains parking information sent by the smart terminal through a server, updates the parking space status information of the garage according to the parking information, and then obtains the user's real-time location, current parking space status information and corresponding parking information after obtaining the guidance request sent by the smart terminal, and selects the guidance vehicle from the vehicles corresponding to all occupied parking spaces. Finally, the present invention generates corresponding guidance light control requests based on all guidance vehicles, and sends them to the guidance vehicles in sequence according to the order of the sections of the optimal guidance path. Finally, the lights of the vehicles parked in the underground garage are controlled to guide the user to the parking position without introducing additional guidance hardware.

[0068] The implementation process of the embodiment of the present invention is described in detail below:

[0069] Traditional, old-style underground garages have complex multi-layer parking lots and are not very intelligent. After users enter the garage, the GPS positioning function of the smart terminal does not work, and the positioning method based on mobile network base stations does not support high-precision underground positioning. As a result, when users face complex underground garages, even if they know the parking location, they cannot quickly determine the moving path.

[0070] In view of the above situation, this embodiment takes into account the gradual expansion of the smart car market and can use the headlights of vehicles parked in the garage to guide the user's driving path so that the user can quickly find the parking location.

[0071] To this end, the specific steps of this embodiment are as follows:

[0072] S1. The server obtains parking information sent by the smart terminal and updates the parking space status information of the garage according to the parking information;

[0073] In a specific implementation, after a user parks their vehicle, the vehicle's on-board computer operates in a low-power standby mode, allowing it to respond to various server requests and feedback the results. Furthermore, the user uses a smart terminal to scan the QR code corresponding to the parking space, generating parking information that is sent to the server. The parking information includes the smart terminal identifier, the vehicle identifier, the parking direction, and the parking position. The parking direction includes a first orientation (i.e., the front of the vehicle is pointing toward the corresponding road section) or a second orientation (i.e., the rear of the vehicle is pointing toward the corresponding road section).

[0074] The server stores a garage map, which includes all parking space location information, parking space status information and driving path information; wherein the parking space status information includes two states: occupied and unoccupied, and each occupied parking space state is associated with a parking information; and the driving path of the garage can be used for pedestrian passage, specifically by It is composed of road sections, each of which can be a line segment with a length of less than 20 meters. The parking spaces on both sides of the line segment are the parking spaces corresponding to the road section, and the vehicles parked in the parking spaces are the vehicles corresponding to the road section.

[0075] S2. After receiving the guidance request sent by the smart terminal, the server obtains the user's real-time location, current parking space status information, and corresponding parking information, and selects the guidance vehicle from all vehicles corresponding to occupied parking spaces;

[0076] In specific implementation, the guidance request can be generated by the user's active operation. However, when in an underground garage, since the user cannot use the positioning module of the smart terminal to obtain the accurate real-time location and send it to the server, the following steps can be used to obtain the user's current location:

[0077] S2.1. Obtain the vehicles corresponding to each road section and select a matching vehicle corresponding to each road section, which can be expressed as:

[0078]

[0079] in, Indicates the garage The vehicles to be matched corresponding to the road sections;

[0080] S2.2. Send a Bluetooth activation request to all vehicles to be matched, and send a Bluetooth ranging request to the smart terminal to obtain the Bluetooth ranging results between the smart terminal and all vehicles to be matched;

[0081] S2.3. Determine the matching vehicle closest to the smart terminal based on the Bluetooth ranging result and use it as the first guiding vehicle;

[0082] S2.4. Send a positioning light turn-on command to the first guide vehicle, and obtain the Bluetooth ranging result between the smart terminal and the first guide vehicle in real time. When the Bluetooth ranging result is less than the first preset distance, the parking position corresponding to the first guide vehicle is used as the user's real-time location.

[0083] This method leverages the limited range of Bluetooth distance measurement, typically within a dozen meters. Within this range, the user can be guided directly to the first guide vehicle's parking location (i.e., the starting point of guidance) by the first guide vehicle's locating lights. These locating lights can be a flashing headlight pattern.

[0084] In addition, since the number of vehicles parked in the underground garage changes dynamically, it is necessary to screen out suitable vehicles for guidance in real time. Therefore, the process of screening out a guiding vehicle from the vehicles corresponding to all occupied parking spaces includes the following steps:

[0085] S2.5. Use the user's vehicle as the first The parking position of the first guiding vehicle (i.e. the last guiding vehicle) is taken as the end point, and the parking position of the first guiding vehicle is taken as the starting point to obtain the optimal guiding path. The optimal guiding path is a path consisting of The directional road segments from the first guide vehicle to the a path for guiding vehicles;

[0086] And the optimal guidance path can be expressed as:

[0087] ,

[0088] in, The optimal driving path a directed road segment;

[0089] S2.6. Obtain a vehicle corresponding to each road section in the optimal driving path as a guide vehicle;

[0090] The optimal driving path The optional leading vehicle for each road segment can be expressed as:

[0091] ,

[0092] Indicates the optimal driving path The first section an optional lead vehicle;

[0093] All the guided vehicles finally obtained It can be expressed as:

[0094] ,

[0095] ,

[0096] Indicates the The guide vehicle corresponding to each road section;

[0097] In the specific implementation, the first guide vehicle of the first section has been determined before, and the The first guide vehicle is the user's parking location, and the rest of the road can be The vehicle with the largest remaining power is ranked first. The guide vehicle corresponding to each road section.

[0098] S3. The server generates corresponding guidance light control requests based on all the guide vehicles and sends them to the guide vehicles in sequence according to the order of the sections of the optimal guidance path.

[0099] In specific implementation, after determining the guide vehicles for each section, it is necessary to control the corresponding guide vehicles to emit guide lights in the order of the sections of the optimal guidance path to guide the user to finally reach the first section. A guiding vehicle (i.e. the parking location of the user's vehicle).

[0100] When generating a guide light control request, in order to more efficiently control the vehicle lights, you first need to determine which vehicle light group to use to emit the guide light (that is, determine the light control object) and the order in which the light control objects light up. Secondly, you need to determine when to emit the guide light. To do this, you can use the following steps:

[0101] S3.1. Determine the guiding light control targets based on the parking direction of each guiding vehicle. Specifically, when the parking direction is a first direction (i.e., the front of the vehicle is facing the corresponding road section), the front turn signals and headlights are the guiding light control targets. When the parking direction is a second direction (i.e., the rear of the vehicle is facing the corresponding road section), the rear turn signals and taillights are the guiding light control targets.

[0102] S3.2. Determine the lighting order of the light-controlled objects based on the direction of the road section corresponding to each guide vehicle;

[0103] Specifically: the lighting order of the light-controlled objects is the same as the direction of the road section. For example, if the direction of the road section corresponds to guiding the vehicle from the left side to the right side, the lighting order of the light-controlled objects is left turn signal - headlight / tail light - right turn signal. Users can walk in the direction of the light.

[0104] S3.3. Acquire all leading vehicles that have not been the target vehicle as candidate target vehicles, send a Bluetooth activation request to the candidate target vehicles, and send a Bluetooth ranging request to the smart terminal to obtain the Bluetooth ranging results between the smart terminal and all candidate target vehicles;

[0105] S3.4. Determine the candidate target vehicle closest to the smart terminal based on the Bluetooth ranging result as the target vehicle;

[0106] S3.5. Obtaining a Bluetooth ranging result between the smart terminal and the target vehicle in real time. When the Bluetooth ranging result is less than a second preset distance, sending a guidance light control request to the target vehicle. The guidance light control request includes light control objects, a lighting order of the light control objects, and a preset light lighting duration.

[0107] After the target vehicle receives the guidance light control request, it can respond to the request and guide the user to walk towards its vehicle.
