[0002] In the current era of human-machine co-driving, autonomous driving particularly requires a display system that can effectively interact with the driver, directly display the perception and behavior capabilities of autonomous driving, and help the driver determine whether autonomous driving can handle the current traffic conditions.

[0003] Currently, most autonomous driving display systems fixedly display the perception content in front of the vehicle, while the content behind the vehicle is mainly warned and displayed by the rearview mirror warning lights. Even when there is a dangerous vehicle moving fast in the target lane during a lane change, only a broad warning effect similar to red radar waves is made beside the vehicle on the display system.

[0024] Figure 3 It is a schematic diagram of the structure of an electronic device according to an embodiment of the present application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present application, the following will clearly and completely describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the embodiments of the present application.

[0026] The following further illustrates the specific implementation of the embodiments of the present application in conjunction with the drawings of the embodiments of the present application.

[0027] First, introduce the parameters involved in the present application:

[0028] For a vehicle moving straight normally, on the in-vehicle human-machine interaction screen, the distance displayed on the front screen of the moving vehicle car1 is x1, the distance displayed on the rear screen of the moving vehicle is y1, the screen height is h, and the model height of the moving vehicle on the screen is carh. The actual distance corresponding to x1 is X1, and the actual distance corresponding to y1 is Y1. The above parameters can be calibrated and set according to the actual situation, such as calibrating and setting according to the screen size and UI interface design, and they are known quantities after calibration. The initial display scale of the screen p = x1 / X1 = y1 / Y1, and the display scale in the top-down view is still this value. In other views, the display scale decreases correspondingly as the distance between the target vehicle and the moving vehicle increases.

[0029] Specifically, for a screen with a height of h = 23 cm, y1 = 2 cm, carh = 1 cm, x1 = h - carh - y1 = 20 cm, s = 8 cm, S = 60 m, X1 is based on the perceivable distance in front of the moving vehicle, assumed to be 150 m, and p = x1 / X1 = 1 / 7.5. Y1 = y1 * p = 15 m, that is, the current screen can display target vehicles perceived by the moving vehicle within a range of 15 m behind the moving vehicle.

[0030] The following combines Figure 1 , and specifically describes a screen display method of the present application. Specifically, Figure 1 is a flowchart of a screen display method provided by an embodiment of the present application. As Figure 1 shown, the method includes the following steps:

[0031] S1. Obtain a target vehicle according to the lane-changing information of the moving vehicle, where the target vehicle is at least one vehicle behind the moving vehicle within a first preset distance threshold.

[0032] The first preset distance threshold can be set as needed, and the present application does not limit this.

[0033] S2. Adjust the display area of the screen according to the actual distance between the target vehicle and the moving vehicle, so that both the moving vehicle and the target vehicle are displayed in the display area of the screen.

[0034] A screen display method provided according to an embodiment of the present application obtains target vehicle information based on the lane change information of a traveling vehicle, where the target vehicle is at least one vehicle behind the traveling vehicle within a first preset distance threshold; adjusts the display area of the screen according to the actual distance between the target vehicle and the traveling vehicle, so that both the traveling vehicle and the target vehicle are displayed in the display area of the screen. Thus, when the traveling vehicle changes lanes, the display area of the screen of the traveling vehicle is automatically adjusted according to the position of the target vehicle behind the traveling vehicle, so that the driver can simultaneously see the traveling vehicle and the target vehicle behind through the interface of the display screen, thereby making a more accurate judgment according to the current driving situation and improving driving safety and driving experience.

[0035] In a possible implementation manner, adjusting the display area of the screen according to the actual distance between the target vehicle and the traveling vehicle so that both the traveling vehicle and the target vehicle are displayed in the display area of the screen can be achieved through the following steps:

[0036] S21. Obtain the screen distance between the target vehicle and the traveling vehicle on the screen according to the actual distance between the target vehicle and the traveling vehicle and the display scale of the screen

[0037] S22. If the actual distance is less than or equal to a second preset distance threshold, adjust the display area of the screen so that the display position of the traveling vehicle on the screen moves up according to the screen distance;

[0038] Set the maximum offset that the display position of the traveling vehicle can move up to be s, s <= h - 2carh - y1, to ensure that the traveling vehicle can still be displayed within the screen and the perception result of a certain distance in front of the traveling vehicle is displayed.

[0039] Where h is the screen height, carh is the model height of the traveling vehicle on the screen, y1 is the screen display distance behind the traveling vehicle, and the actual distance corresponding to s is S = s / p. S can be set as the second preset distance threshold according to needs, and the present application does not limit this.

[0040] When a lane change is triggered, if there is a vehicle behind in the driving rearward perception range, the vehicle closest to the traveling vehicle is selected as the target vehicle car2, and the actual distance between the target vehicle car2 and the traveling vehicle is Y2. The screen distance between the target vehicle car2 and the traveling vehicle on the screen can be calculated as y2 = Y2 * p. When Y2 <= S, that is, when the actual distance is less than or equal to the second preset distance threshold, the display position of the traveling vehicle on the screen is moved up according to the screen distance y2.

[0041] When a lane change is triggered, if there is no vehicle behind in the target lane within the driving rearward perception range, it can be defaulted that the driving vehicle moves up by s to display the perception result behind the driving vehicle. This situation represents that when the driver or the intelligent driving assistance system triggers a lane change, such as when turning on the turn signal, there is no vehicle behind, allowing the driver to confirm no danger from the screen and increasing the driver's trust.

[0042] S23. According to the lane change end information, adjust the display area of the screen so that the display position of the driving vehicle on the screen moves down according to the screen distance.

[0043] After the lane change ends, restore the driving screen in the straight-ahead state, and move the display position of the driving vehicle car1 on the screen down by the screen distance y2 to facilitate the driver to observe the road conditions ahead.

[0044] In the embodiment of the present application, according to the actual distance between the target vehicle and the driving vehicle and the display scale of the screen, the screen distance between the target vehicle and the driving vehicle on the screen is obtained; the screen distance obtained thereby can more accurately reflect the actual vehicle distance. If the actual distance is less than or equal to the second preset distance threshold, adjust the display area of the screen so that the display position of the driving vehicle on the screen moves up according to the screen distance; according to the lane change end information, adjust the display area of the screen so that the display position of the driving vehicle on the screen moves down according to the screen distance. Thus, when the driving vehicle changes lanes, the display angle of the screen is automatically adjusted according to the screen distance, switching the view of displaying the front of the driving vehicle lane to the view of displaying the rear of the target lane where the driving vehicle changes lanes. When the lane change ends or the lane change scenario is cancelled, the display angle of the screen is automatically adjusted to restore the view of displaying the front of the vehicle's own lane, enabling the driver to see both the driving vehicle and the target vehicle behind the driving vehicle when changing lanes, and being able to see the driving environment ahead after the lane change ends, thereby making a more accurate judgment based on the current road conditions and improving driving safety and driving experience.

[0045] In a possible implementation manner, according to the actual distance between the target vehicle and the driving vehicle, adjusting the display area of the screen so that both the driving vehicle and the target vehicle are displayed in the display area of the screen further includes:

[0046] A1. If the actual distance is greater than the second preset distance threshold, reduce the display scale of the screen;

[0047] When the actual distance is greater than the second preset distance threshold, that is, Y2 > S, reduce the screen display scale to p1 = s / Y2, where p1 < p.

[0048] Where Y2 is the actual distance between the target vehicle car2 and the driving vehicle, S is the actual distance corresponding to the maximum offset amount by which the display position of the driving vehicle can move up, p1 is the reduced screen display scale, and p is the initial screen display scale.

[0049] A2. Obtain the screen distance between the target vehicle and the moving vehicle on the screen according to the actual distance between the target vehicle and the moving vehicle and the display scale of the screen;

[0050] A3. Adjust the display area of ​​the screen so that the display position of the moving vehicle on the screen moves up according to the screen distance.

[0051] In an embodiment of the present application, if the actual distance is greater than the second preset distance threshold, the target vehicle cannot be displayed in the display area of ​​the screen due to the screen distance converted according to the original display scale because the actual distance is too large. Therefore, by reducing the display scale of the screen and moving the display position of the moving vehicle on the screen by y2=s, the screen can display the moving vehicle and the target vehicle at the same time.

[0052] Specifically, assuming that the actual distance between the target vehicle car2 and the moving vehicle is Y2=20m, y2=20*1 / 7.5=2.67cm, then the display position of the vehicle on the screen moves up 2.67cm, so that the screen can see whether car2, 20m behind the vehicle car1, is a danger to the vehicle. Assuming that the actual distance between the rear vehicle car2 and the vehicle is Y2=70m>S=60m, which is within the perception range of the rear radar of the intelligent driving vehicle, the display scale p1=s / Y2=8 / 70m=1 / 8.75 should be reduced, and the vehicle moves up s=8cm on the screen. At this time, the maximum distance s has been moved up, but car2 cannot be displayed, so the display scale is reduced from 1 / 7.5 to 1 / 8.75 so that car2 can be seen on the screen.

[0053] This allows the driver to see the moving vehicle and the target vehicle behind it at the same time when changing lanes. When the driver sees from the screen that the intelligent driving system senses a dangerous vehicle coming from behind, the driver will have more control over the intelligent driving system and develop a sense of trust. At this time, the driver can judge whether the lane change can be made smoothly through the screen display. If the lane change is assisted by the intelligent driving system, the driver can also know whether the vehicle's automatic lane change status is normal, thereby making more accurate judgments based on current road conditions, improving driving safety and driving experience.

[0054] In a possible implementation, if the target vehicle is not found behind the moving vehicle according to the lane change information of the moving vehicle, the display area of ​​the screen is adjusted so that the display position of the moving vehicle on the screen moves up by a preset distance.

[0055] The preset distance can be set to the maximum offset s by which the display position of the moving vehicle can be moved upward, and this application does not limit this.

[0056] In an embodiment of the present application, if no target vehicle is found behind the moving vehicle, the display area of the screen is adjusted so that the display position of the moving vehicle on the screen moves up by a preset distance. When the moving vehicle changes lanes and there is no target vehicle behind, that is, there is no potential collision risk, the screen display content is not stupidly displayed as the environment behind the moving vehicle, but the screen display content is switched back to the environment in front of the moving vehicle, that is, the straight-ahead perspective, so that the driver does not see useless information through the screen, improving the driving experience.

[0057] In a possible implementation, obtain the potential collision time between the moving vehicle and the target vehicle;

[0058] According to the potential collision time, identify the display status of the target vehicle as one of the normal status, locked status or dangerous status.

[0059] In an embodiment of the present application, according to the potential collision time between the moving vehicle and the target vehicle, the display status of the target vehicle is identified as one of the normal status, locked status or dangerous status. If the speed of the target vehicle car2 is faster than that of the moving vehicle car1 and the distance is relatively close, and when changing lanes at this time, if the calculated collision time is less than t1, the dangerous status is displayed. If the calculated collision time is greater than t1 and less than t2 (t2>t1), the locked status is displayed, indicating that the intelligent driving perception of the moving vehicle car1 is closely monitoring the situation of the target vehicle car2. At this time, the target vehicle car2 may be switched to the dangerous status at any time. If the calculated collision time is greater than t2, the target vehicle car2 poses no threat to the moving vehicle car1 and can be displayed in the normal status.

[0060] According to the different display effects of the target vehicle, the recognition and judgment of the driving system around the vehicle are displayed, which can convey clearer reminder information to the driver, making it easier for the driver to recognize the current road conditions. Monitor potential collision risk vehicles through the interface of the display system, so as to make more accurate judgments and driving operations according to the current road conditions, improving driving safety and driving experience.

[0061] In a possible implementation, a screen display method is provided. The screen is installed on an autonomous vehicle, and the method includes the following steps:

[0062] B1. According to the lane change information of the autonomous vehicle, obtain the target vehicle, where the target vehicle is at least one vehicle behind the autonomous vehicle within the first preset distance threshold from the autonomous vehicle;

[0063] B2. Adjust the display area of the screen according to the actual distance between the target vehicle and the autonomous vehicle, so that both the autonomous vehicle and the target vehicle are displayed in the display area of the screen, and enable the driver to judge whether to send a driving takeover instruction to the autonomous driving system according to the display content of the screen.

[0064] Any situation of adaptively adjusting the display area of the perspective for the lane change scenario or the curve scenario, including longitudinally, laterally, horizontally and vertically, up and down, left and right, or different combinations of the foregoing, belongs to the scope of the present invention.

[0065] In the embodiment of the present application, in the autonomous driving scenario, according to the lane change information of the autonomous vehicle, a target vehicle is obtained, and the target vehicle is at least one vehicle behind the autonomous vehicle within a first preset distance threshold from the autonomous vehicle; according to the actual distance between the target vehicle and the autonomous vehicle, the display area of the screen is adjusted so that both the autonomous vehicle and the target vehicle are displayed in the display area of the screen, and the driver is enabled to judge whether to send a driving takeover instruction to the autonomous driving system according to the display content of the screen. When the autonomous vehicle changes lanes, the display area of the autonomous driving screen is automatically adjusted according to the position of the target vehicle behind the autonomous vehicle, so that the driver can see the driving conditions of the autonomous vehicle and the target vehicle behind through the interface of the display screen, thereby helping the driver judge the processing situation of the autonomous driving, improving the driver's trust in the autonomous driving system during the process of the autonomous driving system controlling the vehicle to change lanes, reducing the high takeover vehicle frequency caused by the driver's distrust of the autonomous driving system, and enhancing the use experience of the autonomous driving system.
