With the increase of vehicles, the parking lot is built to be larger to meet the parking requirement. Meanwhile, in order to improve the efficiency of the user entering and exiting the parking lot, the entrances and exits in the parking lot are also commonly distributed in various places of the parking lot. Consequently, when a user needs to find a vehicle in a parking lot, it is time-consuming and troublesome to find the vehicle. At present, a camera is arranged on each parking space in a parking lot, so that the vehicle in each parking space can be monitored. The parking lot can also be provided with a vehicle positioning guide device at each entrance, so that a user can inquire the position of the vehicle and can go to a navigation route of the position of the vehicle. The user can go to the position of the vehicle according to the navigation route. Or, the user can also trigger the flickering of the car light or the whistling of the vehicle through the car key in the car searching process, so that the vehicle positioning is realized.
However, the vehicle positioning and guiding device of the parking lot is only arranged at the entrance of the parking lot, and the user cannot continue to be guided to the position of the vehicle after entering the parking lot. When the user realizes vehicle positioning through the key, the flickering effect of the lamp is short after the user presses the key every time, and the vehicle whistling sound is not easy to identify in a noisy environment. Often the user needs to trigger multiple times to find the vehicle. In addition, in the process, the reminding modes such as vehicle lamp flashing, vehicle whistling and the running water effect of the headlights are single, and the reminding modes are not easy to identify in a complex scene. Therefore, the vehicle positioning method in the prior art has the problem of low positioning efficiency.
In addition, currently, there is no function in the market for distinguishing the effect of the user on the distance between the user and the vehicle in the vehicle searching process and continuously reminding. The problems of single reminding mode, lack of individuation and the like exist.
In view of the above problems, the present application provides a vehicle positioning method. The application is applied to the mobile terminal. The mobile terminal can control the time when the light show is turned on by the vehicle. The light show is obtained by carrying out integral optimization arrangement on light in and/or out of the vehicle. The lighting process of the lamplight show can be stored in the vehicle terminal. After the mobile terminal sends a car searching instruction to the vehicle terminal, the vehicle terminal starts a light show function. The light show may include an exterior light set of the vehicle. Such as headlights, turn signals, fog lights, high mounted stop lights. The participation of more car lights can better guide the user on one hand, and on the other hand, the light effect cannot flash in the scene of complex operation. The user can also set up the beautiful effect of light by oneself according to the use habit, increases the individuation of this beautiful light.
In the car searching process of the user, the mobile terminal can acquire the position of the user 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 indicate the vehicle to trigger different light show effects, so that the user can position the vehicle more quickly. For example, when the user moves away from the vehicle, the light show will change the current light frequency accordingly to be more intense, and the sound will also become louder. When the user is continuously approaching the vehicle, the light show resumes its original state. Through these light suggestion, can let the faster location vehicle of user, avoid can't confirm the vehicle under the complex environment, improve user experience. The complex environment can comprise vehicles which are turned on by a plurality of headlights in the dark environment, and at the moment, the change of the light flicker frequency can enable a user to position the vehicles more quickly, so that the vehicles are prevented from being missed.
In addition, the present application can also replace the whistle of a vehicle with sustainable music. The mobile terminal can enable the vehicle to start to play music continuously through instructions. The continuously played music more easily helps the user to distinguish the continuously played music from the whistle of other vehicles, thereby attracting the attention of the user and improving the positioning efficiency. Meanwhile, the background can also push various music to the mobile terminal or the vehicle terminal for the user to select. The user can select favorite music at the mobile terminal or the vehicle terminal, thereby improving personalization.
The technical solution of the present application will be described in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 shows a schematic view of a vehicle positioning scenario provided in an embodiment of the present application. Fig. 1 is a view showing a parking lot. As shown, the parking lot may include a plurality of entrances therein. When a user gets a vehicle from a parking lot, the vehicle cannot be directly positioned due to the fact that the user does not go in and out at the same entrance or exit, the direction is not easy to identify and the like. At this time, the user can send a vehicle searching instruction to the vehicle through the mobile terminal. When the vehicle receives the vehicle searching instruction, the vehicle lamp of the vehicle can start to flash, and the vehicle can start to play music. The user can check whether the lamp of the vehicle flickers or not in the parking lot and distinguish whether the vehicle plays music or not, so that the vehicle can be positioned.

In another example, the first distance may be determined based on a distance between the vehicle and the user at the time the vehicle seek command is triggered. For example, when a vehicle-finding instruction is triggered, the mobile terminal acquires vehicle position information and the current position of the user. And the mobile terminal calculates the initial distance according to the vehicle position information and the current position of the user when the vehicle searching instruction is triggered. The initial distance is the distance between the user and the vehicle when the vehicle starts to be searched. The mobile terminal may determine that a proportion of the initial distance is 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 the play command to the vehicle terminal, the vehicle lamp of the mobile terminal does not flash any more and enters the illumination state. The vehicle will have music as the primary guide to guide the user to find the vehicle.
In another example, the change of the flicker frequency of the vehicle lights and the music playing of the vehicle are not interfered with each other.
In one example, the volume of music played by the vehicle may be adjusted based on the distance between the user and the vehicle. The method comprises the following specific steps:
step 1, determining a playing volume adjustment value of a player of a vehicle according to a first distance and a second distance between a user and the vehicle at the previous moment.
In this step, the mobile terminal may further obtain a second distance between the user and the vehicle at the previous time from the memory. When the user approaches the vehicle, the volume of the playback is decreased. When the user moves away from the vehicle, the volume of the playback increases. The specific formula of the mobile terminal for determining the playing volume adjustment value according to the difference between the second distance and the first distance may be:
playback parameter (second distance-first distance) is playback volume adjustment value
Wherein, the playing parameter is a constant. The value of the playing parameter is an empirical value.
According to the formula, 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 0. When the user is far 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 0. When the second distance is equal to the first distance, the position of the user is not changed, and the playing volume adjustment value is 0. I.e. the volume does not need to be adjusted.
And step 2, sending the playing volume adjustment value to the vehicle terminal so that the vehicle can adjust the playing volume of the player.
In this step, after the mobile terminal calculates the play volume adjustment value, the mobile terminal may send the play volume adjustment value to the vehicle terminal. And the vehicle terminal adjusts the playing volume according to the playing volume adjusting value. Furthermore, the user can more conveniently and quickly locate the vehicle according to the change of the music sound.

In this embodiment, the mobile terminal may be provided with a third distance threshold. After the mobile terminal calculates the first distance, the mobile terminal may compare the first distance with a third distance threshold. When the first distance is less than or equal to the third distance threshold, the mobile terminal may acquire current weather information. And when the weather information is not rainy, the mobile terminal generates a windowing instruction. The mobile terminal may send a windowing instruction to the vehicle terminal. And after the vehicle terminal receives the window opening instruction, opening the vehicle window.
In one example, the mobile terminal may be further provided with a fourth distance threshold. When the mobile terminal has sent a window opening instruction to the vehicle terminal and has not sent a window closing instruction to the vehicle terminal, the mobile terminal may use the first distance to compare with a 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 may send a window closing instruction to the vehicle terminal. And after the vehicle terminal receives the window closing instruction, closing the vehicle window.
In one example, the third distance threshold and/or the fourth distance threshold may be empirical values. For example, the mobile terminal may generate the illumination instruction when the first distance is less than or equal to 2 meters.
In another example, the first distance may be determined based on a distance between the vehicle and the user at the time the vehicle seek command is triggered. For example, when a vehicle-finding instruction is triggered, the mobile terminal acquires vehicle position information and the current position of the user. And the mobile terminal calculates the initial distance according to the vehicle position information and the current position of the user when the vehicle searching instruction is triggered. The initial distance is the distance between the user and the vehicle when the vehicle starts to be searched. The mobile terminal may determine that a proportion of the initial distance is the third distance threshold and/or the fourth distance threshold. Wherein, the ratio of the third distance and the fourth distance may be different. For example, the third distance threshold may be 30% of the initial distance. The fourth distance threshold may be 40% of the initial distance.
According to the vehicle positioning method, the mobile terminal can acquire the current position of the user according to the preset frequency. The mobile terminal may calculate a first distance between the user and the vehicle based on the position of the vehicle and the current position of the user. And when the first distance is smaller than or equal to the first distance threshold value, the mobile terminal sends an illumination instruction to the vehicle terminal so as to enable the vehicle lamp of the vehicle to stop flickering and enter an illumination state. And when the first distance is smaller than or equal to the second distance threshold, the mobile terminal sends a playing instruction to the vehicle terminal so that the vehicle starts the player and plays music. And when the first distance is smaller than or equal to the third distance threshold value and the weather information is that the vehicle is not rainy, the mobile terminal sends a window opening instruction to the vehicle terminal so as to open the vehicle window. In this application, through using illumination instruction, broadcast instruction and the instruction of windowing, improve user experience.
