[0044] In order to make the purposes, technical solutions and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0045] After an autonomous vehicle arrives at a parking lot, a currently empty parking space or a temporary parking space is selected for parking. Due to the limited selection at the time of parking and other factors, for example, only unshielded exposed parking spaces are available at the time of parking, the current location may have poor conditions, for example, unshielded parking spaces may be exposed to the sun.

[0046] The embodiment of the present application provides an automatic parking control method and device for vehicle sun protection, which can identify a target parking space with shelter or no direct sunlight, and can automatically drive from a current parking space to the target parking space and park in the target parking space, thereby effectively avoiding the vehicle from being exposed to the sun and slowing down the aging of the vehicle paint and accessories.

[0047] The method and device are described below through specific embodiments.

[0048] Please refer to Figure 1 , Figure 1 is a flowchart of an automatic parking control method for vehicle sun protection according to an exemplary embodiment of the present application, which is described with reference to Figure 1 , and the method comprises the following steps.

[0049] In step S11, a three-dimensional map model of a parking lot where a vehicle is located and a first preset range around the parking lot is generated.

[0050] In step S12, a model sunshine map with a granularity of seconds in a day is generated on the three-dimensional map model to obtain a sunshine map set.

[0051] In step S13, whether there is a sun protection empty parking space is determined according to the sunshine map set and real-time information of parking spaces in the parking lot, and if there is a sun protection empty parking space, the empty parking space with the shortest sunshine duration in a first preset time period is taken as a target parking space.

[0052] In step S14, the vehicle is controlled to automatically park in the target parking space.

[0053] It should be noted that the technical solution provided in the embodiment can be added to an existing vehicle auxiliary system in the form of a small program, or can be provided as an independent application program to provide an interface to complete the sun protection automatic parking control function; applicable scenarios include but are not limited to automatic parking.

[0054] Specifically, if there is no sun protection empty parking space in the parking lot, an empty parking space with the shortest sunshine duration in the first preset time period is taken as the target parking space, or an empty parking space closest to the vehicle is taken as the target parking space.

[0055] It should be noted that the first preset range is determined according to a parking space selection distance set by automatic parking, and the greater the parking space selection distance set by automatic parking, the greater the first preset range; the three-dimensional map model comprises a three-dimensional model of the parking lot and a three-dimensional model of surrounding buildings; the sun protection empty parking space is an empty parking space with a sunshine duration less than a preset sunshine duration and a sunshine area less than a preset sunshine area in the first preset time period, and the first preset time period is generally a predicted parking time set by a user, and is 2 hours by default; the preset sunshine duration can be set to 70%-100% of the first preset time period; and the preset sunshine area can be set to 60%-100% of the area of the parking space.

[0056] It can be understood that the method provided by the embodiment generates a three-dimensional map model of a parking lot where the vehicle is located and a first preset range around the parking lot, generates a model sunshine map with a second granularity in a day on the three-dimensional map model to obtain a sunshine map set, determines whether there is a sunscreen empty parking space according to the sunshine map set and real-time information of parking spaces in the parking lot, if there is a sunscreen empty parking space in the parking lot, takes a parking space with the shortest sunshine duration in a first preset duration in the sunscreen empty parking space as a target parking space, and controls the vehicle to automatically park in the target parking space. Through the above scheme, the target parking space can be determined and selected before the vehicle automatically parks, the target parking space is a parking space not directly irradiated by the sun, and the vehicle can be effectively prevented from being exposed to the sun to cause aging of the vehicle, thereby effectively prolonging the service life of the vehicle paint and interior.

[0057] In specific implementation, the step S11 of "generating a three-dimensional map model of a parking lot where the vehicle is located and a first preset range around the parking lot" includes: obtaining map data of the parking lot where the vehicle is located and a first preset range around the parking lot from an existing three-dimensional map model; and obtaining the three-dimensional map model according to the map data by using an existing three-dimensional map model generation technology.

[0058] It should be noted that data obtained by scanning the internal and peripheral environment of the parking lot by using the sensors (cameras, laser radars, etc.) of the vehicle can also be added to the map data.

[0059] In specific implementation, the step S12 of "generating a model sunshine map with a second granularity in a day on the three-dimensional map model to obtain a sunshine map set" includes: generating a model sunshine map corresponding to each second according to the geographical position information of the parking lot where the vehicle is located and the current date on the three-dimensional map model; and storing all the model sunshine maps of the day in a set to obtain the sunshine map set.

[0060] It should be noted that the model sunshine map is generated with a second granularity, that is, 60 model sunshine maps are generated per minute.

[0061] In specific implementation, the step S13 of "determining whether there is a sunscreen empty parking space according to the sunshine map set and real-time information of parking spaces in the parking lot" includes: obtaining all the model sunshine maps in a first preset duration after the current time from the sunshine map set as an effective sunshine map set; taking a parking space with a sunshine area less than a preset sunshine area in each model sunshine map of the effective sunshine map set as a candidate parking space; obtaining an empty parking space at the current time as an effective empty parking space according to real-time empty parking space information; and if the position of the candidate parking space is consistent with the position of the effective empty parking space, the candidate parking space is a sunscreen empty parking space.

[0062] It should be noted that the sunshine of all the parking spaces in the parking lot can be seen in each model sunshine map, that is, each model sunshine map represents the sunshine of the parking spaces in one second.

[0063] In the specific implementation, before the automatic parking step, the method further comprises: if there is no sun-proof empty parking space in the parking lot, taking the empty parking space with the shortest sunshine duration in the first preset duration as the target parking space, or taking the closest empty parking space as the target parking space.

[0064] In the specific implementation, the method further comprises: monitoring the temperature in the vehicle in real time; if the temperature in the vehicle is greater than a preset temperature, sequentially executing the step S13 and the step S14.

[0065] It should be noted that the preset temperature is set according to the average monthly temperature in the weather forecast, and the preset temperature range is generally 25-45℃.

[0066] In the specific implementation, the method further comprises: executing the step S13 and the step S14 alternately every second preset duration.

[0067] It should be noted that the second preset duration is less than the first preset duration, and can be generally set to 30-120 minutes.

[0068] In the specific implementation, the method further comprises: acquiring all parking lot information within a second preset range around the vehicle; the parking lot information comprises a parking type and a number of empty parking spaces; selecting a parking lot with a parking type of underground garage and a number of empty parking spaces greater than a preset number as a target parking lot; and finding an empty parking space after the vehicle is navigated to the closest target parking lot and automatically parking in the empty parking space.

[0069] It should be noted that if there is an underground parking lot within the second preset range of the vehicle, the underground parking lot is preferentially selected; the second preset range is generally set according to user demand, and mainly depends on the waiting time of the user to use the vehicle, that is, the duration of the vehicle automatically driving from the parking space to the user-specified location determines the second preset range; the preset number is generally set to more than 10% of the total number of parking spaces in the parking lot, that is, a parking lot with 10% empty parking spaces.
