Description

Driving assistance device and assistance method for monitoring traffic height during vehicle driving
Technical Field
The present invention relates to a driving assistance device for monitoring a traffic level during driving of a vehicle, a driving assistance method for monitoring a traffic level during driving of a vehicle, a corresponding computer program product and a corresponding vehicle.
Background
At present, large-scale business vehicles are more and more favored by people along with the remarkable improvement of the living standard of people. However, many automotive manufacturers have come to deliver large commercial vehicles with extremely large vehicle heights, some approaching 1.8m or even 2 m. However, most of the indoor parking lots are limited to 2m in height and 1.8m in some cases. This results in a large commercial vehicle with a near height limit just being able to drive into the entrance of the parking lot. However, most of such indoor parking lots are complicated in condition, and a lot of pipelines and indication boards are often arranged above the indoor parking lots, so that the indoor spaces of the parking lots do not all have height limits which are greatly higher than the entrances of the parking lots. This makes it possible for the driver of a large commercial vehicle, for example, to be concerned about whether the roof of the vehicle is damaged by being scratched by objects suspended above while driving in such an indoor parking space.
On the other hand, HUDs (Head Up displays) are also receiving increasing attention. Generally, the HUD can project important driving information such as vehicle speed and navigation on a windshield in front of a driver in a virtual display manner, so that the driver can know the information such as vehicle speed and navigation without lowering his head.
However, in the related art, the application to the HUD is basically limited to only information such as vehicle speed and navigation. The psychological burden on the driver of a large commercial vehicle, particularly, caused by interference from an obstacle above while driving in, for example, an indoor parking lot with complicated conditions, cannot be further solved on this basis.

Detailed Description
In order to make the technical problems, technical solutions and advantageous effects of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings and exemplary embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the scope of the invention.
Fig. 1 shows a schematic topology of a driving assistance device 100 for monitoring the traffic level during driving of a vehicle V according to an exemplary embodiment of the invention. The driving assistance apparatus 100 includes at least: a determination module 110, a detection module 120, a comparison module 130, and a display module 140. The determination module 110 is configured and adapted to determine the expected path P travelled by the vehicle V, for example from the current direction of travel of the vehicle V or from path information previously input by the driver into the navigation system of the vehicle V. The detection module 120 is configured and adapted to detect the maximum passable height H1 of the vehicle V on the expected path P, for example by detecting the maximum passable height H1 of the vehicle V on the expected path P through the cooperation of an on-board panoramic camera 121 and a lidar sensor 122 (described below with reference to fig. 2) included in the detection module 120. The comparison module 130 is configured and adapted to compare the maximum passable height H1 with the self height H0 of the vehicle V, for example by determining whether the maximum passable height H1 is much greater than the self height H0 of the vehicle V, for example by a safety height threshold greater than the self height H0 of the vehicle V. The display module 140 is configured and adapted to display auxiliary information on the HUD virtual display surface 141 of the vehicle V according to the comparison result. The display of auxiliary information on the HUD virtual display surface 141 of the vehicle V will be further described below in conjunction with fig. 2-4.
Fig. 2 shows a schematic illustration of a vehicle V with a driving assistance device 100 according to an exemplary embodiment of the invention. As schematically shown in fig. 2, a HUD virtual display surface 141 is provided in front of the vehicle V. As described above, the display module 140 of the driving assistance apparatus 100 is capable of displaying the assistance information on the HUD virtual display surface 141, and a specific example of the assistance information will be described next with reference to fig. 4a and 4 b. The vehicle V has its own height H0. In this case, the vehicle V is, for example, a large commercial vehicle, and thus has a significantly higher height H0, for example 1.9m, than other cars. It is to be understood that the driving assistance device 100 according to the invention is suitable not only for large commercial vehicles but also for small passenger cars or other types of vehicles and means of transport, only for large vehicles, the driver's need for monitoring the height of the passage while driving is more pronounced. The height information about the vehicle's own height H0 should be stored by the vehicle manufacturer in the vehicle's own memory device. Alternatively, the height information about the own height H0 of the vehicle V can also be manually input by the user of the vehicle V into the own storage device of the vehicle V or a memory associated with the driving assistance device 100. As shown in fig. 2, the detection module 120 of the driving assistance apparatus 100 includes at least an on-vehicle panoramic camera 121 and a lidar sensor 122 for cooperatively detecting a maximum passable height H1 of the vehicle V on the intended path P. It should be understood that fig. 2 only schematically illustrates the mounting positions of the vehicle-mounted panoramic camera 121 and the lidar sensor 122 on the vehicle V. Here, the vehicle-mounted panoramic camera 121 and the laser radar sensor 122 should be mountable at any position on the vehicle V as long as detection of the maximum passable height H1 of the vehicle V on the intended path P can be achieved. According to an exemplary embodiment of the present invention, such a detection module 120 comprising an on-board panoramic camera 121 and a lidar sensor 122 may also be referred to as a 360+ panoramic camera system for detecting height information of obstacles around the vehicle V to identify a maximum passable height H1 on the prospective path P.
Fig. 3 shows a view of the environment from the driver's perspective when operating the driving assistance device 100 according to an exemplary embodiment of the present invention. The driving assistance apparatus 100 according to an exemplary embodiment of the invention is configured to be particularly suitable for operation when the vehicle V is in an indoor space. As shown in fig. 3, the driving assistance apparatus 100 is activated when the vehicle V is in an indoor space (more precisely, in an indoor parking lot). Since the speed limit of an indoor parking lot is usually 5 km/h, the current speed of the vehicle V (i.e. in this case not more than 5 km/h) is taken into account when the determination module 110 of the driving assistance device 100 determines the expected path P traveled by the vehicle V, so that the expected path P in the future of the vehicle V is not too long. As already explained in connection with fig. 2, the vehicle V is, for example, a large commercial vehicle and thus has a height H0 of its own (for example 1.9m) which is considerably higher than other cars, so that, even if the entrance of the parking lot (typically limited to a height of 2m) allows the vehicle V to pass through smoothly, due to the complex conditions of such an indoor parking lot, there may be a height somewhere in the parking lot which is insufficient for the vehicle V to pass through, for example due to the lower signs in certain suspension positions in the indoor parking lot. As shown in fig. 3 by way of example, on the intended path P of forward travel of the vehicle V, there is a sign at the top, the lowest point of which is at a height H1 from the ground, which results in a maximum passable height H1 on the intended path P of forward travel of the vehicle V. As shown in fig. 3, the display module 140 displays the assistance information on the HUD virtual display surface 141 of the vehicle V when the driving assistance apparatus 100 is operated. In fig. 3, the HUD virtual display surface 141 is located only at the lower left corner of the forward visual field as viewed by the driver in the vehicle V, but it is understood that the HUD virtual display surface 141 may be located at any position of the forward visual field as long as the assist information can be favorably displayed without obstructing the driving sight of the driver. In this case, the driver of the vehicle V is particularly well aware of the upcoming driving route without lowering his head, and is thus relieved of his driving. In fig. 3, the displayed auxiliary information is only schematically represented by a blank surface, and a specific example of the auxiliary information will be described below with reference to fig. 4a and 4 b.
Fig. 4a and 4b respectively show display interfaces in which the display module 140 of the driving assistance apparatus 100 displays assistance information according to an exemplary embodiment of the present invention. In connection with what has been explained above with reference to fig. 2 and 3, in the case where the vehicle V is a large commercial vehicle and its own height H0 is, for example, 1.9m, when the maximum passable height H1 on the expected path P of the vehicle V is, for example, 2.2m, the auxiliary information displayed by the display interface 140a includes at least: optionally displaying a directional indicator 10a of the desired path P and a prompt 20a regarding the maximum passable height H1. In this example, the direction indicator 10a indicates that the intended path P traveled by the vehicle V is a straight-ahead path. The prompting message 20a includes at least the specific height value information 21a of the maximum passable height H1 on the expected path P of the vehicle V detected by the detection module 120, which is shown here as 2.2m for example. Thus, the maximum passable height H1 (2.2 m in this example) is compared with the own height H0 (1.9 m in this example) of the vehicle V by the comparison module 130, and the comparison result is displayed in the form of "safe" character information 22a, i.e., the vehicle V is safe to travel on the expected path P. In contrast, as exemplarily shown in fig. 4b, the direction indicator 10b displayed on the display interface 140b indicates that the expected path P traveled by the vehicle V is a forward left-turn path, where, in the case where the maximum passable height H1 of the vehicle V on the expected path P detected by the detection module 120 of the driving assistance apparatus 100 is 1.8m, since the maximum passable height H1 is smaller than the own height H0 (here, exemplarily 1.9m) of the vehicle V, the word "dangerous" is given in the character information 22b, and the specific height value (here, exemplarily 1.8m) of the maximum passable height H1 on the expected path P is given at the specific height value information 21 b. This indicates that the vehicle V is dangerous to travel on the intended path P. Alternatively, the safety wording given by the character information 22a can be displayed in a color green, which is normally indicated as safe in traffic regulations, and correspondingly the danger wording given by the character information 22b can be displayed in a color red, which is normally indicated as warning in traffic regulations. Optionally, an acoustic signal output is accompanied in addition to the character information prompt. This further alerts the driver of the vehicle V to a considerable extent whether the path he is about to travel is safe or dangerous. According to an exemplary embodiment of the present invention, which is not shown here, the comparison module 130 of the driving assistance device 100 is configured and adapted to determine whether the height difference between the maximum passable height H1 and the self height H0 of the vehicle V is greater than a safety height threshold, for example 1/10 of the self height H0 of the vehicle V, i.e. when the comparison module 130 determines that the maximum passable height H1 is greater than 1.1 times the self height H0 of the vehicle V, a safe typeface may be given in the character information, otherwise a dangerous typeface may be given. This further ensures safety, for example in view of detection errors or other error conditions, and enables the driver of the vehicle V to recognize in real time whether the path he wishes to travel is indeed safe, and the driver's concern about the occurrence of scratches, in particular from obstacles above, while driving is particularly alleviated when he sees that the words given safe in the character information or the specific height value of the maximum passable height H1 given by the specific height value information are much greater than 1.1 times the own height H0 of the vehicle V.
Fig. 5 shows possible display positions of the display module 140 of the driving assistance apparatus 100 in the vehicle V according to an exemplary embodiment of the present invention. As exemplarily shown in fig. 5, the display module 140 of the driving assistance apparatus 100 is capable of displaying not only the auxiliary information on the HUD virtual display surface 141 as mentioned above, but also the auxiliary information on the console display 142 of the vehicle V. According to an exemplary embodiment of the present invention, the display module 140 may be capable of displaying, in particular, the auxiliary information on the inside mirror 143 and/or the outside mirror 144 of the vehicle V in a case where the determination module 110 of the driving assistance apparatus 100 determines that the expected path P is a reverse path. It is understood that, according to the driving habits of the driver of the vehicle V, in the case where the determination module 110 of the driving assistance apparatus 100 determines that the expected path P is a reverse path, the display module 140 can also display the assistance information on the HUD virtual display surface of the rear windshield, which is particularly suitable when the driver of the vehicle V is used to look back at the reverse situation while backing up. It is further contemplated that the specific location at which the display module 140 displays the auxiliary information can be determined, among other things, by capturing the driver's eye gaze with an indoor camera of the vehicle V. This greatly relieves the driver of the vehicle V of the psychological burden of interference from obstacles above while driving in unknown places, especially in indoor parking lots where the environment is complex.
Fig. 6 shows a flow chart of a driving assistance method for monitoring the traffic level during driving of a vehicle V according to an exemplary embodiment of the invention. The driving assistance method includes at least the steps of:
s100: determining an expected path P traveled by the vehicle V;
s200: detecting a maximum passable height H1 of the vehicle V on the prospective path P;
s300: comparing the maximum passable height H1 with the vehicle V's own height H0;
s400: according to the comparison result, the auxiliary information is displayed on the HUD virtual display surface 141 of the vehicle V.
As described above in conjunction with fig. 5, according to an exemplary embodiment of the present invention, it is determined whether the intended path P traveled by the vehicle V is a forward path or a backward path in step S100, and in the case where the intended path P traveled by the vehicle V determined in step S100 is a backward path, the auxiliary information is additionally displayed on the interior mirror 143 and/or the exterior mirror 144 of the vehicle V in step S400. According to an exemplary embodiment of the present invention, the auxiliary information is additionally displayed on the console display 142 of the vehicle V in step S400, also as described above in connection with fig. 5.
Although specific embodiments of the invention have been described herein in detail, they have been presented for purposes of illustration only and are not to be construed as limiting the scope of the invention. Various substitutions, alterations, and modifications may be devised without departing from the spirit and scope of the present invention.
