Description

Technical Field

[0001] This application relates to the field of intelligent driving technology, and in particular to a parking time estimation method, device, electronic device, and storage medium. Background Technology

[0002] With the development of intelligent driving technology, driver assistance functions have been widely used in daily life, such as Home Automated Valet Parking assist (HAVP). HAVP, based on automatic parking, achieves more comprehensive and automated parking scenarios through features such as route memory and driver assistance.

[0003] In the existing parking process, the vehicle is typically controlled to drive to the target parking space according to the parking route selected by the user after the user triggers the HAVP function and selects the parking route on the user interface, thus completing the parking.

[0004] Real-world parking environments are highly variable and complex. Current HAVP functionality cannot provide information on when users want to know the exact time required to complete parking and determine whether to use it, or when users want to know the remaining time to complete parking and determine whether to end the HAVP session while driving along a parking route. This reduces user convenience. Summary of the Invention

[0039] To make the objectives, technical solutions, and advantages of this application clearer, the application will be further described in detail below with reference to the accompanying drawings. The specific operational methods in the method embodiments can also be applied to the device embodiments or system embodiments. It should be noted that in the description of this application, "multiple" is understood as "at least two". "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. A connected to B can represent: A and B directly connected, and A and B connected through C. Furthermore, in the description of this application, terms such as "first" and "second" are used only for distinguishing the purpose of description and should not be construed as indicating or implying relative importance or order.

[0040] The following explanations of some terms used in the embodiments of this application are provided to facilitate understanding by those skilled in the art.

[0041] The memory parking assist function guides the user from the starting point to the ending point of a pre-defined parking route, parking the vehicle in a space already memorized by the system. The memory parking human-machine interface displays static elements of the parking lot, such as parking spaces, pillars, and speed bumps, as well as dynamic elements like vehicles and pedestrians. It provides intuitive system status information through voice and visual cues. Memory parking also enables functions such as sharp turns, passing, obstacle avoidance, pedestrian avoidance, and rear overtaking avoidance.

[0042] To further illustrate the technical solutions provided in the embodiments of this application, a detailed description is provided below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiments of this application provide method operation steps as shown in the following embodiments or drawings, the method may include more or fewer operation steps based on conventional or non-inventive methods. In steps where there is no logically necessary causal relationship, the execution order of these steps is not limited to the execution order provided in the embodiments of this application. In actual processing or when the device executes the method, it may be executed in the order shown in the embodiments or drawings, or in combination.

[0043] Figure 1This is a flowchart illustrating a parking time estimation method provided in an embodiment of this application. This process can be executed by a parking time estimation device, which can be implemented in software, hardware, or a combination of both. Figure 1 As shown, the process includes the following steps:

[0044] 101: When the memory parking assist function is enabled, in response to the user operation of selecting a target parking route in the first user interface, the number of times the target parking route has been used is obtained.

[0045] In some scenarios, the touchscreen in the memory parking assist function includes a button to activate the memory parking assist function. The user can activate the memory parking assist function by clicking this button on the touchscreen. In another scenario, voice input can also be used, where the command to activate the memory parking assist function can be obtained through voice recognition. This embodiment of the application does not impose any limitations on this method.

[0046] Optionally, the selection of the target parking route on the first user interface can be done by the user touching the first user interface or by voice input. This embodiment of the application does not impose any limitations on this.

[0047] It should be noted that there is no specific limit to the number of memory parking routes included in the first user interface; the target parking route can be one of the routes on this interface. Optionally, the target parking route can also be a route shared by a third party.

[0048] 102: Based on the number of uses and the target parking route, determine the estimated time for the vehicle to complete this parking and display the estimated time on the second user interface.

[0049] Optionally, based on the number of uses and the target parking route, the estimated time for the vehicle to complete this parking session can be determined, which may include the following:

[0050] Scenario 1: When this is the first time using the target parking route, the estimated time for the vehicle to complete this parking is determined based on the route information of the target parking route.

[0051] The route information may include at least one of the following: straight driving sections, turning driving sections, ramp driving sections, intersection driving sections, and speed bump driving sections.

[0052] Optionally, based on the route information of the target parking route, the estimated time for the vehicle to complete this parking can be determined, which may include the following aspects:

[0053] Aspect 1: When the route information is a straight driving segment, the estimated time for the vehicle to complete this parking maneuver is determined based on the straight-line distance of the straight driving segment, the set straight-line speed threshold, and the first weighting factor. Where X1 represents the straight-line distance and V1 represents the straight-line speed threshold. (Characterizing the first weighting factor).

[0054] Aspect 2: When the route information is a turning section, the estimated time for the vehicle to complete this parking maneuver is determined based on the turning distance of the turning section, the set turning speed threshold, and the second weighting factor. Where X2 represents the turning distance, and V2 represents the turning speed threshold. (Characterizing the second weighting factor).

[0055] Aspect 3: When the route information is a slope section, the estimated time for the vehicle to complete this parking maneuver is determined based on the slope distance of the slope section, the set slope speed threshold, and the third weighting factor. Where X3 represents the ramp distance and V3 represents the ramp speed threshold. (Characterizing the third weighting factor).

[0056] Aspect 4: When the route information is an intersection travel segment, the estimated time for the vehicle to complete this parking maneuver is determined based on the intersection distance of the intersection travel segment, the set intersection speed threshold, and the fourth weighting factor. Where X4 represents the distance to the intersection, and V4 represents the speed threshold at the intersection. (Characterizing the fourth weighting factor).

[0057] Aspect 5: When the route information involves a speed bump section, the estimated time for the vehicle to complete this parking maneuver is determined based on the distance to the speed bumps, the set speed bump speed threshold, and the fifth weighting factor. Where X5 represents the distance to the speed bump, and V5 represents the vehicle speed threshold for the speed bump. (Characterizing the fifth weighting factor).

[0058] It should be noted that the target parking route is modeled based on a specific parking scenario. The aspects 1-5 mentioned above are just a few examples, and the embodiments of this application are not limited here. Since the path information of different parking routes is different, their corresponding estimated times are also different.

[0059] For example, when the target parking route is a straight driving route, the estimated time is T1; as another example, when the target parking route is a straight driving route and a turning driving route, the estimated time is T1+T2; as yet another example, when the target parking route is a straight driving route, a ramp driving route, and an intersection driving route, the estimated time is T1+T3+T4.

[0060] Scenario 2: When the number of uses is greater than the first time but less than the first preset threshold (e.g., <4), the estimated time for the vehicle to complete the parking this time is determined based on the first estimated time when the vehicle completed parking using the target parking route for the first time, and the average of the actual time when the vehicle completed parking for the Mth time. Here, M is the value of the previous time. For example, assuming this is the 3rd time using the target parking route, the determined estimated time is the average of the first estimated time, the first actual time, and the second actual time.

[0061] Scenario 3: When the number of uses is greater than or equal to the first preset threshold, the estimated time for the vehicle to complete the parking this time is determined based on the average of the actual times taken to complete parking the vehicle in the previous N times (e.g., the previous 3 times), where N is a preset integer value. For example, assuming this is the 3rd time using the target parking route, the estimated time is the average of the actual times taken in the second, third, and fourth instances.

[0062] Through the above steps, for the target parking route used for the first time, the route is subdivided and the estimated time for passing through each segment is calculated, making the estimated time for the vehicle to complete parking more accurate. For the target parking route used many times, the estimated time for the vehicle to complete parking can be calculated directly based on the average of the previous few times, reducing the amount of calculation and improving data processing efficiency. Then, the estimated time is displayed on the user interface (second user interface) for easy prompting of the user.

[0063] Figure 2 This is a schematic diagram of a user interface for displaying time, provided in an embodiment of this application. The user interface 200 may include a display box 201 for displaying the estimated time for vehicle A to complete parking based on a selected target parking route, and a display box 202 for displaying the remaining time for vehicle A to complete parking while traveling (cruising) along the target parking route. Furthermore, it may include a navigation route map 203 for displaying the route taken by vehicle A from the starting point of the target parking route to the endpoint of the target parking space.

[0064] It should be noted that the above Figure 2 The user interface shown is just an example. In actual parking scenarios, other function boxes can be expanded as needed. For example, the number of straight driving segments and ramp driving segments passed can be displayed on the user interface; or the total distance from the starting point to the destination can be displayed to the user. This application embodiment does not impose any limitations.

[0065] 103: Control the vehicle to drive along the target parking route, determine the remaining time for the vehicle to complete the parking based on the current parking environment, and display the remaining time on the second user interface.

[0066] Optionally, based on the vehicle's current parking environment, the remaining time for the vehicle to complete this parking task can be determined, specifically through the following methods:

[0067] Based on the current parking environment of the vehicle, determine whether there is any obstacle information in front of the vehicle; if so, respond by braking the vehicle and determine the remaining time for the vehicle to complete the parking based on the obstacle information, the vehicle's current geographical location, and the number of times the target parking route has been used; if not, determine the remaining time for the vehicle to complete the parking based on the vehicle's current geographical location and the number of times the target parking route has been used.

[0068] Optionally, the vehicle can be brought to a stop in the following ways:

[0069] Method 1: In response to a user action to stop the vehicle, the vehicle is stopped. For example, when the user notices a sudden event ahead of the target parking route or wants to stop, the user can manually stop the vehicle.

[0070] Method 2: Respond to a detected emergency involving a vehicle that has stopped. For example, while driving along the target parking route, if the parking system detects an event such as someone falling down ahead, causing congestion, a braking command can be generated to control the vehicle to slow down and stop in order to prevent a traffic accident.

[0071] Optionally, to simplify the calculation of remaining time, the remaining time can be calculated based on different usage times. Taking the target parking route information as an example, which includes both straight and turning sections, the following examples can be included:

[0072] Example 1: When using the target parking route for the first time, if the vehicle has just started and has not yet traveled to the straight driving section or the turning driving section, the remaining time is T1+T2 as mentioned above. If the vehicle has traveled a distance on the straight driving section, the remaining time is the sum of the time taken for the vehicle to travel the remaining straight distance and the time taken for the vehicle to travel the remaining turning distance.

[0073] Example 2: When using the target parking route for the second time, the remaining time for the straight driving section is the remaining straight distance divided by the average speed of the first straight driving section; the remaining time for the turning driving section is the remaining turning distance divided by the average speed of the first turning section.

[0074] Example 3: When using the target parking route for the third time, the remaining time for the straight driving section is the remaining straight distance divided by the average speed of the first and second straight driving sections; the remaining time for the turning section is the remaining turning distance divided by the average speed of the first and second turning sections.

[0075] Example 4: For the fourth or more uses of the target parking route, the remaining time for the straight driving segment is the remaining straight distance divided by the average speed of the previous P straight driving segments (P can be an integer value set by 3 or 4); the remaining time for the turning segment is the remaining turning distance divided by the average speed of the previous P turning segments.

[0076] In some embodiments, the remaining time can be calculated in a similar way to the estimated time above. Different road segments have their own corresponding weighting factors, and the remaining time is calculated by combining the respective weighting factors, thereby improving the accuracy of the remaining time.

[0077] In other embodiments, during the cruise along the target parking route, when obstacle information is detected and an unexpected event is analyzed, the time required to bypass the obstacle can be determined. Combined with the remaining time, it can be determined whether the user should be prompted to abandon the current target parking route and park independently, or to choose an alternative route. The specific process is as follows:

[0078] Obstacle information is identified to determine the obstacle avoidance time for the vehicle. Based on the remaining time and obstacle avoidance time, the estimated time for the vehicle to complete the parking maneuver is updated. If the updated estimated time exceeds the second estimated time calculated based on the candidate parking route and obstacle avoidance time, a third user interface pops up. This third user interface includes a prompt indicating whether to continue driving according to the target parking route, as well as a candidate parking route selection button. If the second estimated time is not exceeded, it indicates that the braking time is short and the vehicle can still continue driving according to the target parking route.

[0079] Optionally, the obstacle avoidance time can be determined according to the level of the emergency. For example, if someone faints or falls, the level is A and the obstacle avoidance time is 10 minutes; if goods are being moved, the level is B and the obstacle avoidance time is 5 minutes, etc.

[0080] Optionally, the second estimated time can satisfy the following expression: T ′ =T h +βT r Among them, T h The estimated time, T, is determined based on the route information and usage frequency of candidate parking routes. r β represents the obstacle avoidance time determined based on obstacle information, and β is the probability factor for the occurrence of this sudden event.

[0081] Optionally, the third user interface can be presented as a floating window, located above the second user interface (such as user interface 200), such as... Figure 3 As shown, an exemplary embodiment of this application illustrates a user interface for displaying prompt information.

[0082] The user interface 300 is used to display prompts, such as someone fainting ahead causing congestion, the estimated end time is 10 minutes, the parking time is 15 minutes, and the estimated time for parking using the candidate parking route is 8 minutes. The selection button 301 is a candidate parking route selection button, which allows the user to choose whether to switch to the candidate parking route for parking. It may also include an end button 302 to end the memory parking assistance function.

[0083] It should be noted that the terms "first user interface", "second user interface" and "third user interface" mentioned above are used for descriptive purposes only and do not specifically refer to any one or more user interfaces.

[0084] In this embodiment, when the memory parking assist function is activated, in response to a user's operation of selecting a target parking route in the first user interface, the number of times the target parking route has been used is obtained. Based on the number of uses and the target parking route, the estimated time for the vehicle to complete the parking is determined and displayed on the second user interface. This conveniently informs the user of the time required for the vehicle to complete parking. Furthermore, since the vehicle is controlled to drive along the target parking route, the remaining time for the vehicle to complete the parking is determined based on the current parking environment and displayed on the second user interface. This allows the user to view the remaining time for completing parking in real time and also to know the intermediate process of driving along the target parking route in real time. This optimizes the memory parking assist function and improves the user experience.

[0085] Based on the same technical concept, this application also provides a parking time estimation device, which can implement the parking time estimation method flow described above in this application.

[0087] The acquisition module 401 is used to acquire the number of times the target parking route has been used in response to a user operation that selects a target parking route in the first user interface when the memory parking assist function is enabled.
