Detailed Description

Many driving environment detection systems for detecting the driving environment of a vehicle are known in the art, however, these detection systems are often only capable of automatic driving at the level of L2. In these driving environment detection systems, the detection elements only provide assistance to the driver, and it is the driver who ultimately operates the steering wheel and the throttle of the vehicle. Therefore, these environment detection systems cannot satisfy an autonomous vehicle of L3 level. The driving environment detection system provided by the application is changed and installed as little as possible on the basis of the cab of the original commercial vehicle, so that the driving environment detection system meeting the L3 level automatic driving is realized. In addition, the driving environment detection system disclosed in the present application realizes a driving environment detection system that satisfies the L3 level automatic driving of commercial vehicles in consideration of the specificity of the commercial vehicles in terms of model size running characteristics and the like.

In the field of autonomous driving environment detection systems, the driving environment to be detected includes road features such as road edges, lane lines, traffic signs, and obstacles around the host vehicle such as other vehicles, etc. The driving environment mentioned in the present application includes various types of driving environment features described above.

In the context of the present application, the terms "front", "left", "right", "left/right front" and "left/right rear" are defined relative to the longitudinal direction of travel of the commercial vehicle.

The driving environment detection system 10 disclosed in the present application includes a camera assembly 11; 12. 12', a millimeter wave radar component 31; 32. 32'; 33. 33'; 34. 34' and lidar assembly 21; 22. 22'; 23. 23' wherein the sensors comprised therein are arranged in a surrounding manner around the cabin of the commercial vehicle in order to detect the driving environment in front of and on both sides of the cabin with as little change as possible to the body in white of the cabin and without influencing the functional components of the cabin itself. According to the present application, referring to FIG. 2, a camera assembly 11; 12. 12', a millimeter wave radar component 31; 32. 32'; 33. 33'; 34. 34' and lidar assembly 21; 22. 22'; 23. 23' can form detection ranges around the front and both sides of the cab, respectively, to form sensor redundancy and achieve driving environment detection satisfying automated driving at the level of L3 using sensor fusion technology. The camera head assembly 11 disclosed in the present application; 12. 12', a camera assembly 11; 12. the camera sensors of 12' are arranged in the upper area of the front and both sides of the cab.

In some embodiments of the present application, it can be provided that the camera assembly 11; 12. 12 'includes a forward-facing camera sensor 11 disposed at the front of the cab, a left-side camera sensor 12' and a right-side camera sensor 12 disposed at the left and right sides of the cab, respectively. The forward-facing camera sensor 11 is arranged here above the windscreen of the cab of the commercial vehicle, which on the one hand makes it possible to position the camera as high as possible, so that information C1 (in the direction x of longitudinal travel of the vehicle, see fig. 2) such as traffic signs can be detected, and on the other hand the forward-facing camera sensor 11 can be cleaned by means of the wiper elements arranged on the windscreen itself, so that the special provision of a cleaning mechanism for the forward-facing camera sensor 11 is avoided. Further, left and right camera sensors 12 ', 12 ' and 12 ' are symmetrically disposed above the left and right doors of the cab of the commercial vehicle, respectively, for detecting driving environments C2, C2 ', C3, C3 ' on the left and right sides of the cab and behind the left and right sides (see fig. 2). The arrangement of the left camera sensor 12' and the right camera sensor 12 can achieve a better detection view on the basis of changing the original cab as little as possible.

The forward-facing camera sensor 11 disclosed for the present application comprises a plurality of lenses arranged side by side so as to be able to detect driving conditions at different distances and/or angles in front of the cab. It is contemplated that the lenses may include telephoto lenses, standard lenses, and/or fisheye lenses.

With the left and right camera sensors 12 ', 12' disclosed in the present application, which respectively include the down-view lens and the rear-view lens, wherein the detection direction of the down-view lens is downward with respect to its installation position to obtain the driving environments C3 ', C3 on the left and right sides of the cab, and the detection direction of the rear-view lens is rearward with respect to its installation position, the driving environments C2', C2 behind the left and right sides of the cab can be obtained (see fig. 2). According to some embodiments of the present application, the downward-looking lens comprises a fisheye lens. Other cameras or lenses meeting the detection requirements can of course also be considered.

The millimeter wave radar component 31 disclosed in the present application; 32. 32'; 33. 33'; 34. 34' can detect the driving environment in front of and on both sides of the cab in a surrounding manner by means of their arrangement in the cab. For example, the millimeter-wave radar module 31; 32. 32'; 33. 33'; 34. 34' includes a range millimeter wave radar component 31; 32. 32 'and angular millimeter wave radar components 33, 33'; 34. 34 ', wherein the range millimeter wave radar component is capable of detecting a driving environment at a distance from the driver's cabin, and the angle millimeter wave radar component is primarily used to compensate for an angular range that is not detected by the range millimeter wave radar component. In the above-described angular range, there is no high demand for the detected distance, for example, the left and right sides of the cab, obstacles or lane lines on the left and right sides of the commercial vehicle, or the like. In this case, the range millimeter wave radar module includes a forward range millimeter wave radar 31, a left backward range millimeter wave radar 32 ', and a right backward range millimeter wave radar 32, which have a relatively long detection distance and a comparatively small detection angle range, and are used to cover the driving environment of the front of the cab (R1), the left rear (R2'), and the right rear (R2), respectively (see fig. 3). In order to completely surround the cab, angular millimeter wave radar components 33 and 33' are introduced; 34. 34'. For example, it is considered that the angle millimeter wave radar section includes angle millimeter wave radars provided at end corners where the front surface of the cab meets the left and right sides, respectively, so as to compensate for the detection blind area of the distance millimeter wave radar section. In some embodiments of the present application, it may be provided that, at the end corners, one angular millimeter wave radar 33, 34 is provided at each of the front side (end corner near the junction) and the left side or right side (end corner near the junction) of the cab; 33 ', 34' to cover the driving environment of the cab left/right front and left/right rear, respectively (R31, R32; R31 ', R32', see fig. 3).

In the range millimeter wave radar unit disclosed in the present application, it can be arranged that the forward range millimeter wave radar 31 is disposed in the longitudinal middle of the front lower region of the cab, and the left and right rearward range millimeter wave radars 32' and 32 are respectively symmetrically disposed below the left and right side rear view mirrors of the cab, for better simulating the driving environment for detecting the left and right rear of the cab.

In some embodiments disclosed herein, lidar assembly 21; 22. 22'; 23. 23 ' includes a forward lidar assembly 21 disposed at the front of the cab, a left rearward lidar assembly 22 ' disposed at the left side of the cab, and a right rearward lidar assembly 22 disposed at the right side of the cab, configured to detect a driving environment forward of the cab (L1) and left rearward (L2 ') and right rearward (L2), respectively.

Similar to the millimeter wave radar components described above, in order to compensate for the detection blind areas (L3, L3 ', see fig. 4) of the forward laser radar component 21, the left backward laser radar component 22 ' and the right backward laser radar component 22, the laser radar component disclosed in the present application further includes a blind-supplementary laser radar component 23, 23 ' having a large detection angle range so as to be able to cover the above detection blind areas. That is, these detection blind areas do not require a particularly large detection distance, similar to the case described in the millimeter wave radar section.

According to some embodiments of the present application, wherein the forward lidar assembly 21 is disposed in a lower region of the front of the cab and is positioned above the forward range millimeter wave radar 31. This kind of arrangement has satisfied the higher mounted position that laser radar required because its detection principle (for example if the mounted position is too low, the regional water smoke that produces of vehicle bottom can influence laser radar's detectability in the rainy day) on the one hand to on the other hand has also reformed transform original driver's cabin as far as possible. Furthermore, it is conceivable that the left rear lidar unit 22' and the right rear lidar unit 22 are respectively provided in the door rear regions on both sides of the cab.

In some embodiments of the present application, blind-supplementary lidar assemblies 23, 23' are disposed at the front of the cab near the left and right end regions, respectively, and are capable of covering the above blind detection zones. For example, it is contemplated that forward lidar assembly 21, left rearward lidar assembly 22 ', and right rearward lidar assembly 22 are each configured to include a solid state lidar, and that blind-fill lidar assemblies 23, 23' are configured to include a mechanically rotating lidar.

The present application also discloses a cockpit of a commercial vehicle comprising a driving environment detection system 10 as disclosed in any of the embodiments of the present application.
