[0001] This application relates to the field of parking technology, and more particularly to a parking control method, device, electronic equipment, vehicle, and storage medium. Background Technology

[0002] With the development of automotive intelligence, most cars are equipped with parking assistance functions, which can automatically park the vehicle in the parking space selected by the owner. However, the parking assistance system does not provide a reference for the optimal parking direction, which means that after the vehicle is parked, it receives a large amount of solar radiation due to prolonged exposure to sunlight, leading to problems such as paint damage, interior damage, and high temperature and stuffiness inside the car. Summary of the Invention

[0003] This application provides a parking control method, device, electronic device, vehicle, and storage medium, which aims to avoid problems caused by excessive solar radiation received by the vehicle after parking by determining the optimal parking direction.

[0004] A parking control method, comprising: Acquire parking control data, which includes vehicle location, target date, target time period, and windshield tilt angle; Based on the vehicle location, the target date, the windshield tilt angle, and the vehicle orientation, a windshield radiation model is constructed. Based on the aforementioned windshield radiation model, the vehicle orientation corresponding to the minimum cumulative radiation amount within the target time period is determined as the target vehicle orientation. Based on the orientation of the target vehicle, the target parking direction is determined.

[0005] In this embodiment, a windshield radiation model is first constructed based on the vehicle's location, target date, windshield tilt angle, and vehicle orientation. The solar radiation amount determined by this windshield radiation model is related to input parameters such as vehicle location, target date, windshield tilt angle, and vehicle orientation. The windshield radiation model is solved, and the vehicle orientation corresponding to the minimum cumulative radiation amount within the target time period is determined as the target vehicle orientation. Then, the target parking direction is determined based on the target vehicle orientation. This ensures that when the vehicle is parked based on the target parking direction, the amount of solar radiation received by the vehicle during the target time period can be minimized, thus avoiding problems such as paint damage, interior damage, and high temperature and stuffiness inside the vehicle caused by excessive solar radiation.

[0006] In one embodiment, the windshield radiation model is used to characterize the mapping relationship between solar radiation power and solar irradiance, solar altitude angle, solar azimuth angle, vehicle orientation, and windshield tilt angle. The solar irradiance, solar altitude angle, and solar azimuth angle are all determined based on the target date and the vehicle location.

[0007] In this embodiment, a windshield radiation model is constructed to reflect the mapping relationship between solar radiation power and solar irradiance, solar altitude angle, solar azimuth angle, vehicle orientation, and windshield tilt angle. This model enables the determination of solar radiation power based on the vehicle orientation at different times, given that the solar irradiance, solar altitude angle, and solar azimuth angle are determined according to the vehicle location and target date, and the windshield tilt angle is also determined. This provides a guarantee for determining the target vehicle orientation with the minimum cumulative radiation within the target time period.

[0008] In one embodiment, the solar irradiance is determined based on the solar altitude angle and solar declination; The solar altitude angle and the solar azimuth angle are both determined based on the latitude, solar declination, and hour angle of the vehicle's position; The solar declination is determined based on the target date; The hour angle is determined based on the latitude of the vehicle's position.

[0009] In this embodiment, radiation control parameters related to solar radiation power can be calculated directly or indirectly based on the vehicle's location and the target date. These radiation control parameters include solar irradiance, solar altitude angle, and solar azimuth angle. This makes the determined radiation control parameters dynamically related to the vehicle's current location and date, resulting in higher accuracy of the cumulative radiation amount calculated in the target time period, thus ensuring the overall accuracy of the solution.

[0010] In one embodiment, the solar radiation power is the sum of the solar oblique radiation and the solar direct radiation. The solar oblique radiation is determined based on the solar irradiance, the solar altitude angle, the windshield tilt angle, the solar azimuth angle, and the vehicle orientation. The solar direct radiation is determined based on the solar irradiance, the solar altitude angle, and the windshield tilt angle. The target vehicle orientation is the vehicle orientation that minimizes the integral of the solar oblique radiation during the target time period. The target parking direction is the direction the target vehicle is facing. The direction.

[0011] In this embodiment, since the amount of oblique solar radiation is related to the vehicle's orientation, while the amount of direct solar radiation is independent of the vehicle's orientation, the oblique solar radiation is integrated. The vehicle orientation with the minimum integral value can be determined as the target vehicle orientation. This avoids excessive cumulative radiation, which could lead to problems such as paint damage, interior damage, and high temperatures and stuffiness inside the vehicle. In one embodiment, after determining the target parking direction based on the target vehicle orientation, the method further includes: Get the parking directions of multiple available parking spaces; Determine the directional angle between the target parking direction and the parking direction of each available parking space; The vacant parking space with the smallest directional angle is identified as the target parking space, and the vehicle is controlled to park in the target parking space.

[0012] In this embodiment, the vacant parking space with the smallest directional angle between the target parking direction and the parking space direction is determined as the target parking space. This controls the vehicle to park in the target parking space, minimizing the cumulative radiation received by the vehicle within the target time period. This, in turn, reduces problems such as paint damage, interior damage, and high temperature and stuffiness inside the vehicle caused by prolonged exposure to sunlight.

[0013] In one embodiment, acquiring parking control data includes: When the actual vehicle speed is lower than the preset vehicle speed and a parking activation command is received, the parking control data is acquired.

[0014] In this embodiment, when the measured vehicle speed is less than the preset vehicle speed and a parking activation command triggered by the user is received, it is determined that the vehicle is in a low-speed driving state. At the same time, the user has a subjective need to determine the optimal parking direction. Only then will the relevant process of obtaining parking control data be entered to obtain parking control data so as to determine the target parking direction based on the parking control data, so as to ensure that the determined target parking direction can minimize its solar radiation.

[0015] A parking control device, comprising: The data acquisition module is used to acquire parking control data, which includes vehicle position, target date, target time period, and windshield tilt angle. The model building module is used to build a windshield radiation model based on the vehicle location, the target date, the windshield tilt angle, and the vehicle orientation. The orientation determination module is used to determine the vehicle orientation corresponding to the minimum cumulative radiation amount within the target time period as the target vehicle orientation based on the windshield radiation model. The direction determination module is used to determine the target parking direction based on the orientation of the target vehicle.

Detailed Implementation

[0020] To make the technical problems, technical solutions, and beneficial effects solved by this application clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0021] This application provides a parking control method, which is illustrated by taking the application of the parking control method to an electronic device as an example. The electronic device here can be a controller dedicated to a parking assistance system, or a controller integrated with other functions.

[0022] This application provides a parking control method, such as... Figure 1 As shown, the method includes: S101: Acquire parking control data, including vehicle position, target date, target time period, and windshield tilt angle; S102: Construct a windshield radiation model based on vehicle location, target date, windshield tilt angle, and vehicle orientation; S103: Based on the windshield radiation model, the vehicle orientation corresponding to the minimum cumulative radiation within the target time period is determined as the target vehicle orientation; S104: Determine the target parking direction based on the target vehicle's orientation.

[0023] Parking control data refers to the data that needs to be input during the vehicle parking process.

[0024] The vehicle position refers to the location of the vehicle, specifically the position where the vehicle needs to be parked and stopped. This position can be the real-time location measured by the vehicle's built-in GPS module. The vehicle position includes latitude ϕ (positive for North latitude, unit: °) and longitude λ (positive for East longitude, unit: °).

[0025] The target date refers to the date on which the car needs to be picked up after parking. This target date can be set by the user or determined according to the user's habits.

[0026] The target time period refers to the period during which solar radiation needs to be controlled during parking. This target time period is determined by the start time t1 and the end time t2, i.e., the target time period is [t1, t2], and the unit can be hours. This target time period can be the entire parking cycle or a period before the user-determined vehicle retrieval time. For example, when a user needs to park for a long time, a longer target time period can be set; or, for example, when a user parks during their daily commute, to avoid the car becoming stuffy after get off work, a preset time period before the expected retrieval time (such as after work) can be set as the target time period.

[0027] The windshield tilt angle γ refers to the angle between the windshield and the horizontal plane, measured in degrees. The windshield tilt angle γ of commonly used vehicles is usually 45°-60°. Here, "windshield" refers to the front windshield of the vehicle.

[0028] Among them, the windshield radiation model is a physical and mathematical model used to describe the interaction between solar radiation and the windshield. Its core is used to analyze the reflection, absorption, and transmission laws of solar radiation in the windshield material and the impact of radiation energy on the in-vehicle thermal environment, driver comfort, and equipment safety.

[0029] As an example, in step S101, when the electronic device determines that parking is required, it can obtain parking control data output by the user through the vehicle interface or voice. The parking control data includes vehicle position, target date, target time period, and windshield tilt angle, which are determined by the user according to the actual situation.

[0030] In this example, the electronic device can acquire real-time vehicle data (including but not limited to measured vehicle speed). When the real-time vehicle data meets the parking control conditions, it needs to acquire parking control data input by the user. These parking control conditions are pre-set criteria used to assess whether to enter the parking direction determination process. In this example, user-input parking control data is only acquired when the real-time vehicle data meets the parking control conditions. This avoids frequent entry into the parking direction determination process, which can overload the system and help conserve system resources.

[0031] As an example, in step S102, the electronic device can directly or indirectly calculate radiation control parameters related to solar radiation power based on the vehicle location and target date. These radiation control parameters are determined by the vehicle location and target date and are not limited by vehicle type. Furthermore, the amount of solar radiation is also related to the vehicle's windshield tilt angle γ and the vehicle's orientation. Relatedly, the windshield tilt angle γ was determined before the vehicle left the factory, but the vehicle's orientation... This can be determined by the user. Therefore, it is possible to construct parameters such as solar radiation power and radiation control parameters, windshield tilt angle γ, and vehicle orientation. The mapping model between the input parameters is defined as the windshield radiation model, which enables the windshield radiation model to adapt to different vehicle orientations. By combining the radiation control parameters determined by the vehicle location and target date with the known windshield tilt angle γ, the solar radiation power at each moment is determined. .

[0032] As an example, in step S103, after constructing the windshield radiation model, the electronic device can determine the objective function corresponding to the windshield radiation model. This objective function is related to the vehicle's orientation. A relevant function is used to calculate the cumulative radiation amount within the target time period. Then, the objective function is solved to determine the vehicle orientation corresponding to the minimum cumulative radiation amount within the target time period. This minimum value is then used as the target vehicle orientation to avoid excessive cumulative radiation, which could lead to damage to the vehicle paint, interior damage, and excessive heat and stuffiness inside the vehicle.

[0033] In this example, the solar radiation power is considered. The windshield radiation model is used to determine the integral value between the target time period [t1, t2], which is then defined as the cumulative radiation amount between the target time period [t1, t2]. Therefore, the objective function for determining the minimum cumulative radiation amount between the target time period [t1, t2] is: By adjusting the vehicle's orientation This variable, When it reaches its minimum, orient the corresponding vehicle. The direction of the target vehicle has been determined.

[0034] As an example, in step S104, after determining the target vehicle orientation that minimizes the cumulative radiation within the target time period, the electronic device can transform the input parameter of the target vehicle orientation based on a pre-set mapping function or mapping formula to determine its corresponding parking direction as the target parking direction. Here, the target parking direction can be understood as the optimal parking direction determined based on parking control data, so that subsequent vehicle parking control based on the target parking direction minimizes the cumulative radiation received by the vehicle within the target time period.

[0035] In this embodiment, a windshield radiation model is first constructed based on the vehicle's location, target date, windshield tilt angle, and vehicle orientation. The solar radiation amount determined by this windshield radiation model is related to input parameters such as vehicle location, target date, windshield tilt angle, and vehicle orientation. The windshield radiation model is solved, and the vehicle orientation corresponding to the minimum cumulative radiation amount within the target time period is determined as the target vehicle orientation. Then, the target parking direction is determined based on the target vehicle orientation. This ensures that when the vehicle is parked based on the target parking direction, the amount of solar radiation received by the vehicle during the target time period can be minimized, thus avoiding problems such as paint damage, interior damage, and high temperature and stuffiness inside the vehicle caused by excessive solar radiation.

[0036] In one embodiment, the windshield radiation model is used to characterize the mapping relationship between solar radiation power and solar irradiance, solar altitude angle, solar azimuth angle, vehicle orientation, and windshield tilt angle. Solar irradiance, solar altitude angle, and solar azimuth angle are all determined based on the target date and vehicle location.

[0037] Among them, the vehicle orientation This refers to the direction the windshield faces, measured clockwise from due north, in degrees.

[0038] As an example, electronic devices can determine solar irradiance in relation to solar radiation power based on vehicle location and target date. Solar altitude angle and solar azimuth Radiation control parameters; due to the solar radiation power received by the vehicle's windshield. With solar irradiance Solar altitude angle Sun azimuth Vehicle orientation And it is related to the windshield tilt angle γ, therefore, it can be based on solar radiation power. With solar altitude angle Sun azimuth Vehicle orientation Based on the relationship between the windshield tilt angle γ and the windshield angle, the windshield radiation model is constructed as follows: in, This is the solar oblique radiation component, which is based on the solar altitude angle. Front windshield tilt angle γ, solar azimuth angle and vehicle orientation It is confirmed that it is related to the azimuth of the sun. and vehicle orientation The angle between them is relevant. This is the direct solar radiation component, which is based on the solar altitude angle. The windshield tilt angle γ is determined, and its relationship with the solar azimuth angle is... and vehicle orientation The angle between them is irrelevant.

[0039] In this embodiment, a windshield radiation model is constructed to reflect the mapping relationship between solar radiation power and solar irradiance, solar altitude angle, solar azimuth angle, vehicle orientation, and windshield tilt angle. This model enables the determination of solar radiation power based on the vehicle orientation at different times, given that the solar irradiance, solar altitude angle, and solar azimuth angle are determined according to the vehicle location and target date, and the windshield tilt angle is also determined. This provides a guarantee for determining the target vehicle orientation with the minimum cumulative radiation within the target time period.

[0040] In one embodiment, solar irradiance is determined based on solar altitude angle and solar declination; Both the solar altitude angle and the solar azimuth angle are determined based on the latitude, solar declination, and hour angle of the vehicle's position; Solar declination is determined based on the target date; The hour angle is determined based on the latitude of the vehicle's position.

[0041] As an example, an electronic device can calculate the solar declination based on a target date. Solar declination δ represents the latitude of the point where the sun is directly overhead. Solar declination δ is determined based on the date sequence corresponding to the target date, and can be specifically determined using the following formula: Where N is the date number corresponding to the target date. For example, when the target date is January 1, its date number N is 1; when the target date is February 1, its date number is 32, and so on.

[0042] As an example, electronic devices can determine the time angle based on the local time corresponding to the vehicle's location. Hour angle The difference between the local time and noon representing the vehicle's location is expressed in 15° increments per hour, and can be determined using the following formula: Where t is the local time corresponding to the vehicle's location, in hours. =0° corresponds to noon.

[0043] As an example, electronic devices can be based on the latitude ϕ and solar declination of the vehicle's location. Sum of time angles Determine the solar altitude angle Solar altitude angle Used to characterize the angle between the sun and the horizon, it is related to latitude ϕ and solar declination. Sum of time angles The following relationship exists: Solving the above formula allows us to determine the solar altitude angle. as follows: As an example, electronic devices can also be based on the vehicle's location, latitude ϕ, and solar declination. Sum of time angles Determine the azimuth of the sun. Sun azimuth This refers to the angle formed by rotating clockwise from due north of the observation point to the projection of the sun onto the horizon, and its relationship with latitude ϕ and solar declination. Sum of time angles The following relationship exists: Solving the above formula allows us to determine the solar azimuth angle. as follows: in, (x, y) is a bivariate arctangent function, which can determine the quadrant of the angle based on the signs of x and y, avoiding the limitations of ordinary... Quadrant ambiguity of n.

[0044] As an example, electronic devices can also be based on the solar altitude angle. and solar declination Determine solar irradiance Solar irradiance Solar irradiance refers to the amount of solar radiation energy directly incident on a unit area per unit time, measured in watts per square meter (W / m²). Generally, solar irradiance... Affected by solar altitude angle Solar declination Including the effects of atmospheric attenuation, the calculation formula is as follows: in, =1360 W / m², which is the solar constant. 0.7 is the atmospheric transmittance, specifically the transmittance under cloudless conditions, which can be determined based on the local weather conditions at that time.

[0045] In this embodiment, radiation control parameters related to solar radiation power can be calculated directly or indirectly based on the vehicle's location and the target date. These radiation control parameters include solar irradiance, solar altitude angle, and solar azimuth angle. This makes the determined radiation control parameters dynamically related to the vehicle's current location and date, resulting in higher accuracy of the cumulative radiation amount calculated in the target time period, thus ensuring the overall accuracy of the solution.

[0046] In one embodiment, the solar radiation power is the sum of the solar oblique radiation and the solar direct radiation. The solar oblique radiation is determined based on solar irradiance, solar altitude angle, windshield tilt angle, solar azimuth angle, and vehicle orientation. The solar direct radiation is determined based on solar irradiance, solar altitude angle, and windshield tilt angle. The target vehicle orientation is the orientation of the vehicle whose integral of the solar oblique radiation is minimum over the target time period; The target parking direction is the direction the target vehicle is facing. The direction.

[0047] As an example, the windshield radiation model constructed by an electronic device is as follows: The above windshield radiation model can be converted into the following formula: in, This refers to the amount of solar radiation at an oblique angle, specifically solar irradiance. and the component of oblique solar radiation The product of the solar oblique component, which is based on the solar altitude angle. Front windshield tilt angle γ, solar azimuth angle and vehicle orientation It is confirmed that it is related to the azimuth of the sun. and vehicle orientation The angle between them is relevant. This refers to direct solar radiation, specifically solar irradiance. and the component of direct sunlight The product of the solar direct component and the solar altitude angle. The windshield tilt angle γ is determined, and its relationship with the solar azimuth angle is... and vehicle orientation The angle between them is irrelevant.

[0048] In this example, due to the difference between the amount of solar oblique radiation and the solar azimuth angle... and vehicle orientation The angle between them is related, while the amount of direct solar radiation is related to the solar azimuth angle. and vehicle orientation The angle between them is irrelevant and is determined based on the vehicle position and the target date. Therefore, the vehicle orientation corresponding to the minimum integral value of the solar oblique radiation during the target time period [t1, t2] can be determined as the target vehicle orientation. The specific processing procedure is as follows: Integrating the solar oblique radiation over the target time period [t1, t2], the following formula is determined: Will Expand into Then the formula in step (A) can be transformed into the following formula: By differentiating the formula in step (B), we can determine that... At that time, it can make The calculated minimum cumulative radiation value can be used to determine the target vehicle orientation, thus avoiding excessive cumulative radiation that could lead to damage to the vehicle's paint, interior, and excessive heat inside the vehicle.

[0049] As an example, after determining the orientation of the target vehicle, the electronic device needs to adjust the orientation of the target vehicle. The 360° modulus is used to standardize the angles in all directions within a single value between 0° and 360°, eliminating potentially redundant full-circle rotation angles in the target vehicle's orientation, for subsequent parking control. In this example, the target parking direction can be... Sure.

[0050] In one example, assuming the vehicle's location is at latitude ϕ=39.9°N and longitude λ=116.4°E, the target date is the summer solstice (N=172), the target time period is 8:00-18:00, and the windshield tilt angle γ=60°, the process for determining the vehicle's target parking direction is as follows: Determine solar declination based on the target date .

[0051] The time angle can be determined based on the local time corresponding to the vehicle's location. When the local time is noon, the calculated hour angle =0°.

[0052] Based on latitude ϕ and solar declination Sum of time angles Determine the solar altitude angle and solar azimuth , ,and .

[0053] The calculated solar irradiance at local noon time W / m².

[0054] Based on solar radiation power With solar altitude angle Sun azimuth Vehicle orientation And the windshield tilt angle γ, to construct a windshield radiation model.

[0055] The amount of oblique solar radiation in the front windshield radiation model is integrated to determine... Solve the above This allows for a symmetrical distribution of azimuth angles. The value is approximately negative, therefore the sun is mainly to the south of the vehicle's location, from which the target vehicle's orientation can be calculated. 0° (due north) means parking the vehicle facing north with the windshield away from the sun to reduce radiation and achieve the minimum cumulative radiation during the target time period.

[0056] Finally, the target vehicle's orientation The model is 360°, which will be converted into a standardized target parking direction, i.e. This is to ensure that when a vehicle is parked in the target parking direction, its cumulative radiation during the target time period can be effectively reduced, so as to avoid problems such as paint damage, interior damage, and high temperature and stuffiness inside the vehicle caused by excessive solar radiation.

[0057] In one embodiment, such as Figure 2 As shown, after step S104, that is, after determining the target parking direction based on the target vehicle's orientation, the method further includes: S201: Obtain the parking direction of multiple available parking spaces; S202: Determine the angle between the target parking direction and the direction of each available parking space; S203: Identify the vacant parking space with the smallest directional angle as the target parking space and control the vehicle to park in the target parking space.

[0058] Here, "vacant parking space" refers to a parking space that is currently vacant. "Parking space direction" refers to the axial direction of the parking space.

[0059] As an example, in step S201, the electronic device can obtain the parking space direction of multiple vacant parking spaces by communicating with the parking lot monitoring system. Alternatively, during the vehicle's parking space patrol mode, it can collect parking space images through the vehicle's camera or other devices, analyze the parking space images, and determine whether a parking space is vacant. At the same time as determining vacant parking spaces, it also determines the parking space direction corresponding to each vacant parking space.

[0060] As an example, in step S202, the electronic device can calculate the angle between the calculated target parking direction and the parking direction of each available parking space to determine the directional angle between the two.

[0061] As an example, in step S203, the electronic device can compare the directional angles corresponding to multiple vacant parking spaces, determine the vacant parking space with the smallest directional angle as the target parking space, and control the vehicle to park in the target parking space so that the cumulative radiation received by the vehicle during the target time period after parking in the target parking space is minimized, thereby mitigating to some extent the problems of paint damage, interior damage, and high temperature and stuffiness inside the vehicle caused by prolonged exposure to sunlight.

[0062] For example, when an electronic device determines that the target parking direction is north, if the directions of multiple available parking spaces include north, the angle between them is 0, and it can directly identify the available parking space facing north as the target parking space. If the directions of multiple available parking spaces do not include north, and are restricted to east or west, then the angle between the north and east directions is calculated as follows: The angle between the north and west directions is Therefore, the vacant parking spaces corresponding to the east direction need to be identified as target parking spaces.

[0063] In this embodiment, the vacant parking space with the smallest directional angle between the target parking direction and the parking space direction is determined as the target parking space. This controls the vehicle to park in the target parking space, minimizing the cumulative radiation received by the vehicle within the target time period. This, in turn, reduces problems such as paint damage, interior damage, and high temperature and stuffiness inside the vehicle caused by prolonged exposure to sunlight.

[0064] In one embodiment, step S101, namely acquiring parking control data, includes: When the actual vehicle speed is lower than the preset vehicle speed and a parking activation command is received, parking control data is acquired.

[0065] Among these, the measured vehicle speed refers to the vehicle speed measured in real time. The preset vehicle speed refers to a pre-set vehicle speed used to assess whether the measured vehicle speed meets a minimum standard; for example, the preset vehicle speed could be set to 10 km / h. The parking activation command is a pre-set command used to activate the recommended parking direction.

[0066] As an example, when the vehicle is in driving mode, the electronic device needs to obtain the vehicle's actual speed. When the actual speed is compared with the preset speed, the electronic device controls the vehicle to enter parking mode. At this time, the parking module of the intelligent driving system can silently search in the background without being actively activated by the user, waiting to receive the parking activation command triggered by the user. Alternatively, intelligent driving systems that do not have silent background search can directly wait to receive the parking activation command triggered by the user. After the electronic device receives the parking activation command triggered by the user, it can activate the parking module to enter the parking patrol mode and open a thread in the parking module to calculate the target parking direction of the vehicle.

[0067] In this example, when the actual vehicle speed is less than the preset speed and a parking activation command is received, the electronic device will periodically monitor the vehicle's position and lighting conditions. The specific monitoring can be determined by a light sensor or a forward-facing camera. For example, the vehicle's built-in GPS module can continuously monitor the vehicle's position and collect other parking control data through the vehicle-machine interaction system or voice commands, so as to determine the target parking direction later.

[0068] In this embodiment, when the measured vehicle speed is less than the preset vehicle speed and a parking activation command triggered by the user is received, it is determined that the vehicle is in a low-speed driving state. At the same time, the user has a subjective need to determine the optimal parking direction. Only then will the relevant process of obtaining parking control data be entered to obtain parking control data so as to determine the target parking direction based on the parking control data, so as to ensure that the determined target parking direction can minimize its solar radiation.

[0069] This application provides a parking control method that improves the logic processing of the parking system within the driving system without altering the existing logical relationships between components. Figure 3 As shown, the specific steps include the following: First, determine whether the vehicle has entered driving mode; if yes (Y), proceed to step (2); if no, end the parking control process directly.

[0070] When the vehicle enters driving mode, it needs to determine whether the vehicle is traveling at a low speed; if yes (Y), proceed to step (3); if no, the parking control process ends directly. The determination of whether the vehicle is traveling at a low speed specifically determines whether the actual vehicle speed is less than the preset vehicle speed.

[0071] When the vehicle is traveling at low speed, the driving system will enter the patrol mode. The patrol mode here refers to the operating mode in which the vehicle automatically or semi-automatically patrols specific areas such as warehouses, storage areas, and parking lots according to preset routes, rules, or instructions.

[0072] When the vehicle enters the patrol mode, the GPS module or other positioning module can periodically monitor the vehicle's location and collect information on the vehicle's lighting conditions.

[0073] Determine whether the user has activated the parking function, i.e., determine whether the parking activation command triggered by the user has been received; if yes, proceed to step (6); if no, end the parking control process directly.

[0074] When a user activates the parking function, the target parking direction needs to be determined based on parking control data such as vehicle location, target date, target time period, and windshield tilt angle.

[0075] Determine the target parking space based on the target parking direction, and park the vehicle in the target parking space according to the target parking direction.

[0076] The parking control method provided in this example can enrich the parking direction recommendation problem in the intelligent driving system, and can maximize the sun protection of the front row and dashboard of the vehicle, so as to minimize the amount of solar radiation received by the windshield during the target time period and achieve the best sun protection effect.

Figure 4 As shown, it includes: Data acquisition module 401 is used to acquire parking control data, which includes vehicle position, target date, target time period and windshield tilt angle; The model building module 402 is used to build a windshield radiation model based on the vehicle location, the target date, the windshield tilt angle, and the vehicle orientation. Orientation determination module 403 is used to determine the vehicle orientation corresponding to the minimum cumulative radiation amount within the target time period as the target vehicle orientation based on the windshield radiation model. The direction determination module 404 is used to determine the target parking direction based on the orientation of the target vehicle.

[0078] This application also provides an electronic device 500, such as... Figure 5 As shown, it includes a memory 501 and a processor 502, wherein the memory 501 is used to store computer programs; the processor 502 is used to execute the programs stored in the memory 501 to implement the parking control method described in any embodiment of this application.
