With the increase of vehicles, the parking lot is built bigger and bigger to meet the parking demand. Simultaneously, in order to improve the user's entry and exit efficiency in the parking lot, the entrances and exits in the parking lot are also usually distributed in various places of the parking lot. Subsequently, when a user needs to find a car in a parking lot, how to find his own vehicle has become a time-consuming and troublesome matter. At present, the parking lot can monitor the vehicles in each parking space by installing a camera in each parking space. The parking lot can also be equipped with vehicle positioning guidance equipment at each entrance for users to query the location of the vehicle and the navigation route to the location of the vehicle. The user can go to the location of the vehicle according to the navigation route. Alternatively, the user can also use the car key to trigger the flickering of the lights or the whistle of the vehicle during the process of finding the car to locate the vehicle.

However, the vehicle positioning guidance equipment in the parking lot is only set at the entrance of the parking lot, and cannot continue to guide the user to the location of the vehicle after the user enters the parking lot. When the user locates the vehicle through the key, the flickering effect of the car light is short every time the key is pressed, and the sound of the vehicle whistle is difficult to recognize in a noisy environment. Often users need to trigger multiple times to find the vehicle. Moreover, in this process, the reminder methods such as flashing lights, honking of vehicles, and the flowing water effect of headlights are single, which are not easy to identify in complex scenes. Therefore, the vehicle positioning method in the prior art has the problem of low positioning efficiency.

In addition, the current market does not have the function of distinguishing the distance between the user and the vehicle during the process of looking for a car, and continuously reminding the user. There are problems such as a single reminder method and a lack of personalization.

In view of the above problems, the present application proposes a vehicle positioning method. This application applies to mobile terminals. The mobile terminal can control the timing of the vehicle turning on the light show. The light show is obtained through an overall optimized arrangement for the lights inside and/or outside the car. The lighting process of the light show can be saved in the vehicle terminal. After the mobile terminal sends a car search command to the vehicle terminal, the vehicle terminal turns on the light show function. The light show may include the vehicle's exterior light sets. For example, headlights, turn signals, fog lights, high mounted brake lights. The participation of more car lights can better guide the user on the one hand, and on the other hand, the lighting effect in the complex operation scene will not flash by. Users can also set the light show effect by themselves according to their usage habits, increasing the personalization of the light show.

During the user's car search process, the mobile terminal can obtain the user's location in real time. The mobile terminal can calculate the distance between the user and the vehicle in real time. The mobile terminal can send different instructions to the vehicle according to the distance between the user and the vehicle to instruct the vehicle to trigger different light show effects, so that the user can locate the vehicle more quickly. For example, when the user moves away from the vehicle, the light show will correspondingly change the current light frequency and become more intense, and the sound will also become louder. When the user continues to approach the vehicle, the light show returns to its original state. Through these light prompts, the user can locate the vehicle more quickly, avoid being unable to determine the vehicle in a complex environment, and improve the user experience. Among them, the complex environment can include, in a dark environment, there are many vehicles with headlights turned on around. At this time, the change of the light flashing frequency can enable the user to locate the vehicle faster and avoid missing it.

In addition, the present application can also use sustainable music to replace the horn of the vehicle. The mobile terminal can make the vehicle start to play music continuously through instructions. The music played continuously can more easily help the user to distinguish it from the whistle of other vehicles, thereby attracting the attention of the user and improving the positioning efficiency. At the same time, the background can also push a variety of music to the mobile terminal or vehicle terminal for users to choose. Users can improve personalization by selecting their favorite music on the mobile terminal or vehicle terminal.

The technical solution of the present application will be described in detail below with specific embodiments. The following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

Fig. 1 shows a schematic diagram of a scene of vehicle positioning provided by an embodiment of the present application. Figure 1 is a schematic diagram of a parking lot scene. As shown, multiple entrances and exits may be included in the parking lot. When the user goes to the parking lot to pick up the car, it may not be possible to directly locate the vehicle due to reasons such as not entering and exiting at the same entrance and exit, and difficult to identify the direction. At this time, the user can send a car search instruction to the vehicle through the mobile terminal. When the vehicle receives the car search instruction, the lights of the vehicle can start to flash, and the vehicle can start to play music. The user can locate the vehicle by checking whether the lights of the vehicle are flashing in the parking lot and identifying whether the vehicle is playing music.

In this application, the mobile terminal is used as the execution subject to execute the vehicle positioning method in the following embodiments. Specifically, the execution subject may be a hardware device of a mobile terminal, or a software application implementing the following embodiments in the mobile terminal, or a computer-readable storage medium installed with a software application implementing the following embodiments, or implementing Code for the software application of the embodiments described below.

Fig. 2 shows a flow chart of a vehicle positioning method provided by an embodiment of the present application. On the basis of the embodiment shown in Figure 1, as shown in Figure 2, with the mobile terminal as the execution subject, the method of this embodiment may include the following steps:

S101. Acquire a first distance between a user and a vehicle at a current moment according to a preset frequency.

In this embodiment, the mobile terminal can acquire the current location of the user in real time. Alternatively, the mobile terminal may acquire the current location of the user according to a preset frequency. After the mobile terminal acquires the current location of the user, the mobile terminal can calculate the first distance between the user and the vehicle according to the location of the vehicle and the current location of the user. Wherein, the position of the vehicle can be obtained from the vehicle when the mobile terminal sends a vehicle search instruction to the vehicle. Alternatively, the vehicle's position can be obtained from the cloud. The cloud can obtain the location of the vehicle from the vehicle terminal when the user parks.

S102. According to the first distance and the second distance between the user and the vehicle at the last moment, determine the adjustment value of the flicker frequency of the vehicle light.

In this embodiment, the mobile terminal can also acquire the second distance between the user and the vehicle at the last moment from the memory. The mobile terminal can determine whether the user is approaching the vehicle or moving away from the vehicle according to the first distance and the second distance. When the user approaches the vehicle, the blinking frequency of the lights needs to be reduced. The mobile terminal may determine a blinking frequency adjustment value less than 0 according to the first distance and the second distance. Or, the blinking frequency of the lights needs to increase when the user moves away from the vehicle. The mobile terminal may determine a blinking frequency adjustment value greater than 0 according to the first distance and the second distance.

In an example, the mobile terminal may determine the flicker frequency adjustment value according to the difference between the second distance and the first distance. Its specific formula can be:

Frequency parameter * (second distance - first distance) = flashing frequency adjustment value

Among them, the frequency parameter is a constant. The value of the frequency parameter is an empirical value.

It can be known from the calculation according to the formula that when the user approaches the vehicle, the second distance is smaller than the first distance. The difference between the second distance and the first distance is less than zero. When the user is away from the vehicle, the second distance is greater than the first distance. The difference between the second distance and the first distance is greater than zero. When the second distance is equal to the first distance, the position of the user does not change, and the adjustment value of the flashing frequency of the vehicle light is 0. That is, the headlights do not need to be adjusted.

S103. Send the flicker frequency adjustment value to the vehicle terminal, so that the vehicle can adjust the flicker frequency of the vehicle lights.

In this embodiment, after the mobile terminal calculates the adjusted value of the flicker frequency, it may send the adjusted value of the flicker frequency to the vehicle terminal. The vehicle terminal adjusts the flickering frequency of the vehicle light according to the flickering frequency adjustment value. Furthermore, the user can locate the vehicle more conveniently according to the change of the flickering frequency of the vehicle light.

In the vehicle positioning method provided by the present application, the mobile terminal can obtain the user's current location according to a preset frequency. The mobile terminal can calculate the first distance between the user and the vehicle according to the position of the vehicle and the current position of the user. The mobile terminal can also acquire the second distance between the user and the vehicle at the last moment from the memory. The mobile terminal can determine whether the user is approaching the vehicle or moving away from the vehicle according to the first distance and the second distance. The mobile terminal may determine the adjustment value of the blinking frequency of the vehicle light according to the first distance and the second distance between the user and the vehicle at the last moment. The mobile terminal can send the flicker frequency adjustment value to the vehicle terminal. The vehicle terminal adjusts the flickering frequency of the vehicle light according to the flickering frequency adjustment value. In this application, by adjusting the flickering frequency of the vehicle light according to the distance between the user and the vehicle, the effect of improving the positioning efficiency of the user in positioning the vehicle in the parking lot is achieved, and the user experience is improved.

Fig. 3 shows a flow chart of a vehicle positioning method provided by an embodiment of the present application. On the basis of the embodiment shown in Figure 1 and Figure 2, as shown in Figure 3, with the mobile terminal as the execution subject, the method of this embodiment may include the following steps:

S201. Obtain a car search instruction, which is triggered when a user clicks a car search button on a mobile terminal.

In this embodiment, the user can open the car-finding APP on the mobile terminal. The mobile terminal can trigger a car-finding instruction when the user clicks a car-finding button on the interface of the car-finding APP. Alternatively, the mobile terminal may trigger a car-finding instruction when the car-finding APP is turned on.

S202. Send a car search command to the vehicle terminal to wake up the vehicle terminal of the vehicle.

In this embodiment, the mobile terminal can send the car search instruction to the vehicle terminal. The vehicle terminal is awakened when obtaining the vehicle search instruction. The awakened vehicle terminal can execute the light show script stored in the memory of the vehicle terminal. When the vehicle terminal executes the light show script, the vehicle lights start to flash. The awakened vehicle terminal can also feed back vehicle location information to the mobile terminal. The location information may be latitude and longitude coordinates.

S203. Obtain vehicle location information fed back by the vehicle terminal.

In this embodiment, the mobile terminal obtains the vehicle location information fed back by the vehicle terminal.

S204. Acquire the first distance between the user and the vehicle at the current moment according to the preset frequency.

S205. According to the first distance and the second distance between the user and the vehicle at the last moment, determine the adjustment value of the blinking frequency of the vehicle light.

S206. Send the flicker frequency adjustment value to the vehicle terminal, so that the vehicle can adjust the flicker frequency of the vehicle lights.

Wherein, steps S204 to S206 are implemented in a manner similar to that of steps S101 to S103 in the embodiment of FIG. 2 , and will not be repeated here in this embodiment.

In the vehicle location method provided by the present application, the mobile terminal can trigger a car search command when the user clicks the car search button on the interface of the car search APP. The mobile terminal can send the car-finding instruction to the vehicle terminal. The vehicle terminal is awakened when obtaining the vehicle search instruction. The awakened vehicle terminal can execute the light show script stored in the memory of the vehicle terminal. The awakened vehicle terminal can also feed back vehicle location information to the mobile terminal. The mobile terminal can obtain the current location of the user according to a preset frequency. The mobile terminal can calculate the first distance between the user and the vehicle according to the position of the vehicle and the current position of the user. The mobile terminal can also acquire the second distance between the user and the vehicle at the last moment from the memory. The mobile terminal can determine whether the user is approaching the vehicle or moving away from the vehicle according to the first distance and the second distance. The mobile terminal may determine the adjustment value of the blinking frequency of the vehicle light according to the first distance and the second distance between the user and the vehicle at the last moment. The mobile terminal can send the flicker frequency adjustment value to the vehicle terminal. The vehicle terminal adjusts the flickering frequency of the vehicle light according to the flickering frequency adjustment value. In this application, by adjusting the flickering frequency of the vehicle light according to the distance between the user and the vehicle, the effect of improving the positioning efficiency of the user in positioning the vehicle in the parking lot is achieved, and the user experience is improved.

Fig. 4 shows a flowchart of a vehicle positioning method provided by an embodiment of the present application. On the basis of the embodiments shown in Figures 1 to 3, as shown in Figure 4, with the mobile terminal as the execution subject, the method of this embodiment may include the following steps:

S301. Acquire a first distance between the user and the vehicle at the current moment according to a preset frequency.

Wherein, the implementation manner of step S301 is similar to that of step S101 in the embodiment of FIG. 2 , and will not be repeated here in this embodiment.

S302. When the first distance is less than or equal to the first distance threshold, send a lighting instruction to the vehicle terminal, so that the vehicle lights stop blinking and enter the lighting state.

In this embodiment, the mobile terminal may be set with a first distance threshold. After the mobile terminal calculates the first distance, the mobile terminal may use the first distance to compare with the first distance threshold. When the first distance is less than or equal to the first distance threshold, the mobile terminal may generate a lighting instruction. The mobile terminal can send lighting instructions to the vehicle terminal. After receiving the lighting instruction, the vehicle terminal stops flashing the vehicle light. At the same time, the vehicle terminal turns on the lights of the vehicle, so that these lights enter the lighting state.

In an example, the first distance threshold may be an empirical value. For example, when the first distance is less than or equal to 2 meters, the mobile terminal may generate a lighting instruction.

In another example, the first distance may be determined according to the distance between the vehicle and the user when the car search instruction is triggered. For example, when a car search instruction is triggered, the mobile terminal acquires vehicle location information and the user's current location. The mobile terminal calculates the initial distance according to the vehicle location information and the user's current location when the car search command is triggered. The initial distance is the distance between the user and the vehicle when the vehicle search is started. The mobile terminal may determine a certain proportion of the initial distance as the first distance threshold. For example, the first distance threshold may be 30% of the initial distance. That is, when the initial distance is 10 meters, the first distance threshold is 3 meters.

S303. When the first distance is less than or equal to the second distance threshold, send a play instruction to the vehicle terminal, so that the vehicle turns on the player and plays music.

In this embodiment, the mobile terminal may be set with a second distance threshold. After the mobile terminal calculates the first distance, the mobile terminal may use the first distance to compare with the second distance threshold. When the first distance is less than or equal to the second distance threshold, the mobile terminal may generate a play instruction. The mobile terminal can send the playing instruction to the vehicle terminal. After receiving the playing instruction, the vehicle terminal controls the vehicle terminal to start playing music.

In an example, the second distance threshold may be an empirical value. For example, when the first distance is less than or equal to 2 meters, the mobile terminal may generate a lighting instruction.

In another example, the first distance may be determined according to the distance between the vehicle and the user when the car search instruction is triggered. For example, when a car search instruction is triggered, the mobile terminal acquires vehicle location information and the user's current location. The mobile terminal calculates the initial distance according to the vehicle location information and the user's current location when the car search command is triggered. The initial distance is the distance between the user and the vehicle when the vehicle search is started. The mobile terminal may determine a certain proportion of the initial distance as the second distance threshold. For example, the second distance threshold may be 30% of the initial distance. That is, when the initial distance is 10 meters, the second distance threshold is 3 meters.

In one example, after the mobile terminal sends a play instruction to the vehicle terminal, the vehicle light of the mobile terminal stops blinking and enters the lighting state. The vehicle will use music as the main guide to guide users to find the vehicle.

In another example, the change of the blinking frequency of the vehicle lights and the music playing of the vehicle do not interfere with each other.

In one example, the volume of music played by the vehicle can be adjusted according to the distance between the user and the vehicle. Its specific steps may include:

Step 1. According to the first distance and the second distance between the user and the vehicle at the last moment, determine the playback volume adjustment value of the player of the vehicle.

In this step, the mobile terminal can also acquire the second distance between the user and the vehicle at the last moment from the memory. As the user approaches the vehicle, the volume played decreases. As the user moves away from the vehicle, the volume of the playback increases. The mobile terminal can determine the playback volume adjustment value according to the difference between the second distance and the first distance, and the specific formula can be:

Play parameter*(second distance-first distance)=play volume adjustment value

Among them, the playback parameter is a constant. The value of the playback parameter is an experience value.

It can be known from the calculation according to the formula that when the user approaches the vehicle, the second distance is smaller than the first distance. The difference between the second distance and the first distance is less than zero. When the user is away from the vehicle, the second distance is greater than the first distance. The difference between the second distance and the first distance is greater than zero. When the second distance is equal to the first distance, the user's position does not change, and the playback volume adjustment value is 0. That is, the volume does not need to be adjusted.

Step 2. Send the playback volume adjustment value to the vehicle terminal, so that the vehicle can adjust the playback volume of the player.

In this step, after the mobile terminal calculates and obtains the adjustment value of the playback volume, it may send the adjustment value of the playback volume to the vehicle terminal. The vehicle terminal adjusts the playback volume according to the playback volume adjustment value. Furthermore, the user can locate the vehicle more conveniently according to the change of the music sound.

S304. When the first distance is less than or equal to the third distance threshold and the weather information indicates that it is not raining, send a window opening instruction to the vehicle terminal, so that the vehicle windows are opened.

In this embodiment, the mobile terminal may be set with a third distance threshold. After the mobile terminal calculates the first distance, the mobile terminal may use the first distance to compare with the third distance threshold. When the first distance is less than or equal to the third distance threshold, the mobile terminal can acquire current weather information. When the weather information is that it is not raining, the mobile terminal generates a window opening instruction. The mobile terminal can send a window opening command to the vehicle terminal. After receiving the window opening command, the vehicle terminal opens the window.

In an example, the mobile terminal may also be set with a fourth distance threshold. When the mobile terminal has sent the window opening instruction to the vehicle terminal but has not sent the window closing instruction to the vehicle terminal, the mobile terminal may use the first distance to compare with the fourth distance threshold. When the first distance is greater than or equal to the fourth distance threshold, the mobile terminal may generate a window closing instruction. The mobile terminal can send a window closing instruction to the vehicle terminal. After receiving the window closing instruction, the vehicle terminal closes the vehicle window.

In an example, the third distance threshold and/or the fourth distance threshold may be empirical values. For example, when the first distance is less than or equal to 2 meters, the mobile terminal may generate a lighting instruction.

In another example, the first distance may be determined according to the distance between the vehicle and the user when the car search instruction is triggered. For example, when a car search instruction is triggered, the mobile terminal acquires vehicle location information and the user's current location. The mobile terminal calculates the initial distance according to the vehicle location information and the user's current location when the car search command is triggered. The initial distance is the distance between the user and the vehicle when the vehicle search is started. The mobile terminal may determine a certain proportion of the initial distance as the third distance threshold and/or the fourth distance threshold. Wherein, the ratios of the third distance and the fourth distance may be different ratios. For example, the third distance threshold may be 30% of the initial distance. The fourth distance threshold may be 40% of the initial distance.

In the vehicle positioning method provided by the present application, the mobile terminal can obtain the user's current location according to a preset frequency. The mobile terminal can calculate the first distance between the user and the vehicle according to the position of the vehicle and the current position of the user. When the first distance is less than or equal to the first distance threshold, the mobile terminal sends a lighting instruction to the vehicle terminal, so that the vehicle lights stop blinking and enter the lighting state. When the first distance is less than or equal to the second distance threshold, the mobile terminal sends a play instruction to the vehicle terminal, so that the vehicle turns on the player and plays music. When the first distance is less than or equal to the third distance threshold and the weather information is not raining, the mobile terminal sends a window opening command to the vehicle terminal, so that the vehicle windows are opened. In this application, user experience is improved by using lighting instructions, playing instructions and window opening instructions.
