Abstract
Description
Technical Field
[0001] This application relates to autonomous driving technology, and more specifically, to technologies related to automatic parking reminders. Background Art
[0002] There is a problem in the radar wave detection of the parking space to be parked by the automatic parking space reminder system that the time difference Δt is too large, resulting in a situation where the actual parking space width is insufficient, but the system misreports that the parking space has sufficient width.
[0003] Figure 1 The principle of the traditional automatic parking space reminder system is illustrated. As Figure 1 shown, when the automatic parking space reminder system of the vehicle 10 to be parked detects the adjacent vehicle 30 on one side of the parking space 20 during the process of the vehicle 10 entering the parking space 20 to be parked, it records the time t'1 when the edge line 301 of the adjacent vehicle 30 is detected. However, due to the relatively backward position of the line end of the real edge line of the vehicle 10 to be parked because of the vehicle body design, the line end of the edge line 301 detected by the lidar is not the real edge line. The real edge line should be detected at the time t1. Therefore, the time difference Δt’ calculated by the vehicle 10 to be parked according to the following formula (1) is too large, and the real time difference Δt should be calculated according to formula (2):
[0004] Δt’ = t2 - t'1 (1)
[0005] Δt = t2 - t1 (2)
[0006] Wherein, t2 is the time when the vehicle 10 to be parked detects the edge line 321 of the adjacent vehicle 32 on the other side of the parking space 20 to be parked.
[0007] Because the calculated time difference is greater than the real time difference, it causes the vehicle 10 to be parked to make a misjudgment on the parking space 20. It is necessary to provide an improved parking space reminder solution. Summary of the Invention

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the embodiments of the present application will be described clearly and completely below with reference to the drawings. It should be noted that the described embodiments are only some of the embodiments of the technical solutions of the present application, rather than all of them. All other embodiments obtained by those of ordinary skill in the art based on the embodiments described in this application document without creative efforts are covered by the protection scope of the present application.
[0019] Figure 2This is a schematic structural diagram of an automatic parking space reminder system according to an example of the present application. As Figure 2 shown, the system includes a position detection component 40, a vehicle networking communication module 42, a processor 44, and an output component 46.
[0020] The position detection component 40 is arranged on the vehicle to be parked and is configured to detect the position outside the first vehicle and the position inside the second vehicle. The first vehicle is located on the first side of the parking space to be parked, and the "outside" here refers to the side of the first vehicle away from the parking space to be parked. The second vehicle is located on the second side of the parking space to be parked, and the "inside" is the side of the second vehicle adjacent to the parking space to be parked. The position detection component 40 is, for example, a lidar. As an alternative or supplement, the position detection component 40 may further include a camera. The vehicle networking communication module 42 can be arranged on the vehicle to be parked and is used to obtain the body width of the first vehicle. The vehicle networking communication module can obtain the body width of the first vehicle from the background or directly from the first vehicle. The background here includes the service end of the vehicle networking, such as a remote server, etc. The processor 44 is arranged on the vehicle to be parked and is configured to calculate the distance difference from the outside of the first vehicle to the inside of the second vehicle according to the position outside the first vehicle and the position inside the second vehicle, and determine the available width of the parking space to be parked based on the distance difference and the obtained body width of the first vehicle; and is further configured to generate a prompt signal for reminding whether the parking space is available or not according to the determined available width. The processor 44 is, for example, the body controller of the vehicle or any on-vehicle controller such as the vehicle's overall vehicle controller. The output component 46 is arranged on the vehicle to be parked and is configured to output the prompt signal.
[0021] Figure 3 This is a schematic principle diagram of an automatic parking space reminder system according to an example of the present application. Referring simultaneously to Figure 2 and Figure 3 .
[0022] The vehicle 50 to be parked is to be parked in the parking space 52 to be parked. An automatic parking space reminder system as shown in Figure 2 is arranged on the vehicle 50 to be parked. In this example, when the vehicle 50 to be parked enters the large area around the parking space 52 to be parked, it drives from the direction close to the first vehicle 60. When the vehicle 50 to be parked travels to position A as shown in the figure, the position detection component 40 detects the position outside the first vehicle 60. More specifically, the lidar senses the edge line 60 A of the first vehicle 60. According to some examples of the present application, the position detection component 40 records the time T when the outside edge line 60A of the first vehicle 60 is sensed A . As the vehicle 50 to be parked continues to travel, for example, when it travels to position B, the position detection component 40 detects the position inside the second vehicle 62. More specifically, the lidar senses the inside edge line 62B of the second vehicle 62 and records the time T when it is sensedB Meanwhile, the vehicle networking communication module 42 obtains the body width W1 of the first vehicle 60 from the background.
[0023] The position detection component 40 sends the data it detects to the processor 44, and the vehicle networking communication module 42 sends the obtained body width W1 to the processor 44. The processor 44 calculates the distance difference from the outer side of the first vehicle to the inner side of the second vehicle based on the outer position of the first vehicle and the inner position of the second vehicle, determines the available width of the parking space to be parked according to the calculated distance difference and the obtained width of the first vehicle; and is further configured to generate a prompt signal for prompting whether the parking space is available or unavailable according to the determined available width. Specifically, the processor 44 can be based on the time T A and the time T B calculate the time for the vehicle 50 to travel from the edge line 60A to the edge line 62B, and then combine the vehicle speed obtained from the vehicle's vehicle controller to determine the distance S from the edge line 60A to the edge line 62B AB The processor 44 further calculates the difference between the distance S AB and the body width W1, and this difference is the actual width of the parking space 52 to be parked. The processor 44 compares this actual width with the body width of the vehicle itself. If the actual width is greater than the body width, it is considered that the parking space 52 is available, otherwise it is considered that the parking space 52 is unavailable.
[0024] In this embodiment, the vehicle 50 to be parked senses the outer edge line 60A of the first vehicle 60 that it first encounters when driving towards the parking space 52. According to the prior art, the vehicle 50 to be parked senses the inner edge line of the first vehicle 60 instead of the outer edge line. It can be understood that when the vehicle is about to reach position A, the lidar is blocked by the head of the first vehicle 60 and cannot accurately sense the inner edge line of the first vehicle 60 to be sensed, but the sensing of the outer edge line 60A is relatively accurate because it is not blocked. Therefore, the width of the parking space to be parked determined according to the embodiment of the present application is more accurate.
[0025] Figure 4 is a structural diagram of an automatic parking space reminder system according to some other examples of the present application. As Figure 4 shown, the system includes a vehicle 80 to be measured, a vehicle 70 to be parked, and a background 90.
[0026] The vehicle 80 to be measured includes a body control module 800 and a vehicle networking communication module 802. The body control module 800 is used to record the position of the vehicle itself, and the vehicle networking communication module 802 transmits the position of the vehicle itself and the width information of the vehicle itself to the background 90. As an example, the vehicle 80 to be measured includes the first vehicle and the second vehicle described above in combination with the examples. Among them, the vehicle 80 to be measured includes a positioning system, and thus can obtain its own position information.
[0027] The vehicle 70 to be parked includes a vehicle networking communication module 702, a position detection component 700, a body controller 704, and an output component 706. The vehicle networking communication module 702 receives the width information of the vehicle 80 to be measured from the background 90. The position detection component 700 detects the outer position of the first vehicle in the vehicle 80 to be measured and detects the inner position of the second vehicle in the vehicle 80 to be measured. The first vehicle is located on the first side of the parking space to be parked, and the second vehicle is located on the second side of the parking space to be parked. The first vehicle, the parking space to be parked, and the second vehicle are, for example, the first vehicle 60, the parking space 52, and the second vehicle 62 described above. The body controller 704 calculates the distance difference from the outer side of the first vehicle to the inner side of the second vehicle according to the outer position of the first vehicle and the inner position of the second vehicle, and determines the available width of the parking space to be parked based on the distance difference and the width of the first vehicle obtained; and is further configured to generate a prompt signal for reminding that the parking space is available or unavailable according to the determined available width. The body controller 704 is, for example, the processor 44 described above or includes the processor 44. The output component 706 outputs the prompt signal, such as the output component 46 described above.
[0028] In this application, the output component in each example may be a voice output component or a display screen or a combination of a voice output component and a display screen.
[0029] This application also provides a vehicle, Figure 5 which is a schematic structural diagram of the vehicle. As Figure 5 shown, the vehicle includes a vehicle networking communication module 500, a position detection component 502, a controller 504, and an output component 506.
[0030] The vehicle networking communication module 500 is configured to transmit the position of the vehicle itself and the body width information of the vehicle itself to the background and receive the information transmitted by the background. The position detection component 502 is configured to detect the outer position of the first vehicle and detect the inner position of the second vehicle. The first vehicle is located on the first side of the parking space to be parked, the outer side is the side of the first vehicle away from the parking space to be parked, the second vehicle is located on the second side of the parking space to be parked, and the inner side is the side of the second vehicle adjacent to the parking space to be parked, where the parking space to be parked is Figure 5 the parking space where the vehicle itself shown is to be parked. The controller 504 is configured to calculate the distance difference from the outer side of the first vehicle to the inner side of the second vehicle according to the outer position of the first vehicle and the inner position of the second vehicle, and determine the available width of the parking space to be parked based on the distance difference and the width of the first vehicle; and is further configured to generate a prompt signal for reminding that the parking space is available or unavailable according to the determined available width; wherein, the width of the first vehicle is included in the information transmitted by the background. The output component is configured to output the prompt signal. Exemplarily, Figure 5 the vehicle shown may be the one described above in combination with Figure 2 , Figure 3 and Figure 4The vehicle to be parked in the described example. However, compared with the vehicle to be parked in the example described above, Figure 5 The vehicle shown is configured to transmit its location to the background. Suppose Figure 5 The vehicle shown has parked in a parking space, and the empty parking space is next to it. At this time, this vehicle is the vehicle to be detected for other vehicles to be parked. Thus, Figure 5 The location of the vehicle shown transmitted to the background helps the vehicle to be parked at this time to determine whether the parking space to be parked is appropriate according to this application.
