Description

[Technical Field]

[0001] The present disclosure relates to a camera monitor system (CMS) for use in a commercial truck or similar vehicle, and in particular to a CMS infrared LED for improved nighttime visibility. [Background technology]

[0002] Mirror replacement systems, and camera systems that supplement mirror views, are utilized in commercial vehicles to enhance the vehicle operator's ability to view the surrounding environment. Camera monitor systems (CMS) utilize one or more cameras to provide the vehicle operator with an enhanced field of view. In some instances, CMSs cover a larger field of view than traditional mirrors or include a field of view that is not entirely available through traditional mirrors.

[0003] A typical CMS has camera arms positioned on each side of the vehicle to provide Class II and Class IV views. Displays are mounted on the A-pillars on both the driver's and passenger's sides to simulate a traditional mirror by displaying the field of view of the camera arm on that side.

[0004] Nighttime driving of commercial vehicles is difficult due to poor visibility. To improve nighttime visibility, the use of infrared light-emitting diodes (IR LEDs) has been proposed in CMS systems. IR LEDs generate heat that must be managed during use. IR LEDs have various other limitations that limit their usefulness during typical driving operations. Summary of the Invention

[0034] The embodiments, examples and alternatives of the preceding paragraphs, the claims, or the following description and drawings, including any of their various aspects or their respective individual features, may be taken independently or in any combination. Features described in connection with one embodiment are applicable to all embodiments, except where such features are incompatible. Like reference numbers and symbols in the various drawings indicate like elements. DETAILED DESCRIPTION OF THE INVENTION

[0035] Schematic diagrams of a commercial vehicle 10 are shown in FIGS. 1A and 1B. The vehicle 10 includes a vehicle cab or tractor 12 for towing a trailer 14. It should be understood that the vehicle cab 12 and / or trailer 14 may be of any configuration. While commercial trucks are contemplated in this disclosure, the present invention is applicable to other types of vehicles. The vehicle 10 incorporates a camera monitor system (CMS) 15 (FIG. 2) that includes driver and passenger side camera arms 16a, 16b mounted on the exterior of the vehicle cab 12. If desired, the camera arms 16a, 16b may also include conventional mirrors integrated therewith, although in some examples, the CMS 15 may be used to replace mirrors entirely. In additional examples, multiple camera arms may be included on each side, with each arm housing one or more cameras and / or mirrors. Each arm 16a, 16b may also provide a housing enclosing electronics, e.g., a controller, configured to provide various features of the CMS 15.

[0036] Each camera arm 16a, 16b includes a base fixed to, for example, the cab 12. A pivoting arm is supported by the base and may be articulated relative thereto. At least one rear-facing camera 20a, 20b is disposed within each camera arm 16a, 16b. Each exterior camera 20a, 20b has an exterior field of view (FOV) that includes at least one of a Class II view and a Class IV view (FIG. 1b), which are legally defined views in the commercial trucking industry. EX1 , FOV EX2 A Class II view of a given side of the vehicle 10 is a subset of a Class IV view of the same side of the vehicle 10. If desired, multiple cameras may be used on each camera arm 16a, 16b to provide these views. For example, Class II and Class IV views are defined in the European R46 legislation, which establishes similar driver visibility requirements for commercial trucks in the United States and other countries. References to "Class" views are not intended to be limiting, but rather as an illustration of the type of view provided on the display by a particular camera.

[0037] First and second video displays or monitors 18a, 18b are positioned on the driver's side and passenger's side, respectively, within the vehicle cab 12 on or near the A-pillars 19a, 19b (generally, A-pillars 19) and display Class II and Class IV views on each side of the vehicle 10, which provide rearward along-the-vehicle views captured by exterior cameras 20a, 20b.

[0038] If video of Class V and / or Class VI views is also required, camera housing 16c and camera 20c may be located at or near the front of vehicle 10 to provide these views (FIG. 1b). A third display 18c located within cab 12 near the top center of the windshield can be used to display Class V and Class VI views forward of vehicle 10 to the driver. Displays 18a, 18b, 18c (generally, displays 18) face toward a driver area 24 within cab 22, where a driver / operator is seated in driver's seat 26. The location, size, and field of view(s) streamed to a particular display may vary from the configurations described herein and still encompass the invention of this disclosure.

[0039] If a Class VIII view is desired, camera housings may be positioned on the sides and rear of the vehicle 10 to provide a field of view that includes some or all of the Class VIII zone of the vehicle 10. In such an example, the third display 18c may include one or more frames that display the Class VIII view. Alternatively, additional displays may be added near the first, second, and third displays 18a, 18b, 18c to provide a dedicated display that provides the Class VIII view.

[0040] 2, each display 18a, 18b (or others, as desired) includes a housing mounted to the respective A-pillar 19 (i.e., 19a, 19b), for example, by a bracket, or integrated into the vehicle trim. A screen 28 (i.e., 28a, 28b) is mounted to the front of the housing facing the driver. The screen 28 may be any suitable screen, such as TFT, LCD, LED, OLED, and the like. A controller 30 may communicate with the camera 20 and the display 18, perform image processing, execute algorithms related to CMS functions, or include other desired features of the CMS 15.

[0041] 1A and 1B, there are specific areas around the vehicle 10 that must be monitored by the driver while driving, including first and second target areas T1, T2. The first target area T1 is on the side of the trailer 14, and the second target area T2 is located at or near the end of the trailer 14.

[0042] These target areas are particularly important to monitor during reversing or docking operations, especially at night. Prior art CMSs equipped with infrared LEDs may provide some infrared illumination to the first target area T1, but any infrared light will have an intensity of substantially 0.00 μW / cm at the trailer end. 2 14. No illumination is provided in second target area T2 because the focused infrared LEDs are too diffused, such as at 100° F. Second target area T2 covers the vertical target area adjacent the trailer, as well as the ground and part of the vehicle between the vertical target area and the focused infrared LEDs themselves (e.g., the ground generally adjacent the end of the trailer). Thus, such a system essentially renders the driver blind to the end of the trailer 14 at night.

[0043] To address the above-mentioned deficiencies, the disclosed CMS 15 uses both a diffused infrared LED 21 and a focused infrared LED 121, as shown in FIG. 2. Each of the infrared LEDs 21, 121 may be provided by one or more individual infrared LEDs, if desired. The diffused infrared LED 21 and the focused infrared LED 121 are configured to illuminate first and second target areas T1, T2, respectively, with infrared light, thereby providing the driver with sufficient nighttime visibility while operating the vehicle. The infrared LEDs 21, 121 are operated by a controller 30 in response to one or more inputs 50. The inputs 50 include at least one of an ambient light sensor, a reverse switch, image recognition software, a steering angle sensor, and / or a vehicle speed sensor. The infrared LEDs 21, 121 may be controlled by a manual input button or a combination of buttons via a menu structure.

[0044] A typical trailer 14 has a length L ranging from 12 m to 20 m. trailer The camera arm 16 is positioned approximately 2 m from the front of the trailer (L cab ) Generally, the camera arm 16 is positioned at a distance L from the trailer end. total The second target area T2 is mounted on the tractor 12 at a distance of 14 m to 22 m from the focused infrared LEDs 121, which is typically 14 m to 22 m from the focused infrared LEDs 121. The bottom of the trailer 14 is located approximately 0.5 m to 1.5 m from the ground on which the trailer rests (i.e., the trailer deck). Therefore, the second target area T2 is located 14 m to 22 m from the focused infrared LEDs 121 and 0.5 m to 1.5 m from the ground. The second target area T2 is configured to have an intensity of at least 0.4 μW / cm 2 In another example, the focused infrared LED 121 preferably illuminates the second target area T2 with an infrared light intensity of at least 1.0 μW / cm 2 and in another example, the infrared light intensity is at least 3.0 μW / cm 2 is.

[0045] Current infrared LEDs do not provide the desired focused infrared light at the trailer end. Different lights are provided by infrared LEDs with different designs. The diffused infrared LED 21 and the concentrated infrared LED 121 each include at least one of primary and secondary optics. Alternatively, instead of separate, discrete infrared LEDs, a compound lens, bifocal lens, shaved lens, and / or similar lenses can provide both the concentrated and diffused infrared LEDs. This second target area T2 may also include the dock, trailer, trailer wheels, and the ground adjacent to the wheels (e.g., areas requiring high visibility during nighttime docking / backing operations). Examples of primary optics are lens designs, including lens shapes. Examples of secondary optics are reflectors and TIR optics.

[0046] Referring to FIG. 3 , the concentrated infrared LED 121 has a lens 60 with a beam axis 62 where the infrared light has the highest intensity. The infrared intensity gradually decreases from the beam axis 62. The beam angle 64 is the angle where the light intensity reaches 50% of the maximum light intensity, and the field angle 66 is the angle where the light intensity reaches 10% of the maximum light intensity. At least one of the primary optics and the secondary optics is different from each other to provide different first and second beam angles. In this example, the diffused infrared LED 21 has a lens different from the lens of the concentrated infrared LED 121. The diffused infrared LED 21 has a wide beam angle to illuminate the first target area T1, and the concentrated infrared LED has a very narrow beam angle to reach the second target area T2 and provide sufficient illumination for the driver.

[0047] The housing of camera arm 16 is shown schematically in FIG. 4. Camera 20 provides a Class II and / or Class IV view encompassing first and second target areas T1, T2. Display 18 is configured to display the field of view; however, in low light conditions (e.g., less than 1 lux), camera 20 cannot display a useful image 18 unless the field of view is illuminated by infrared light. To this end, a diffuse infrared LED 21 is proximate (e.g., mounted) to the housing and provides a first beam angle, and a focused infrared LED 121 is proximate (e.g., mounted) to the housing and provides a second beam angle that is smaller than the first beam angle. In this manner, diffuse infrared light is provided to first target area T1, and focused infrared light is provided to second target area T2.

[0048] While the CMS 15 may turn the infrared LEDs on and off together under certain circumstances, if desired, it may be desirable to illuminate each target area during different scenarios based on different operating conditions. For example, the controller 30 is configured to operate the diffuse infrared LEDs 21 in a first condition to provide diffuse infrared light to the first target area T1. The first condition may be typical nighttime driving while the vehicle 10 is traveling forward, which provides diffuse light without “hot spots” that could distract from or obscure the visibility of objects outside the immediate target area (i.e., only the diffuse infrared LEDs are turned on). In another example, the controller 30 is configured to operate the concentrated infrared LEDs 121 in a second condition different from the first condition to provide focused infrared light to the second target area T2. The second condition may correspond to a nighttime reverse docking operation (e.g., turning on both the diffuse and concentrated infrared LEDs, since the diffuse infrared LEDs may also be beneficial). It may also be desirable to illuminate the first target area T1 during nighttime backing up to improve visibility. Input 50 is used by controller 30 to identify conditions and operate the infrared LEDs as desired.

[0049] The second target area T2 is movable relative to the focused infrared LEDs 121 on the tractor 12 based on the angle of the trailer relative to the tractor 12, i.e., during a turning maneuver (e.g., T21, T22, T23 in FIG. 6). In one example, the controller 30 is configured to aim the focused infrared LEDs 121 onto the second target area T2 during movement so that the end of the trailer remains illuminated with infrared light.

[0050] In one example shown in Figure 4, the concentrated infrared LED 121 is provided by an array of multiple individual infrared LEDs 121a, 121b, 121c, 121d. When the trailer 14 is at or near a trailer angle of 0°, the infrared LEDs 121 closest to the tractor 12 are turned on and the others are turned off. As the trailer angle increases, the infrared LEDs farther from the tractor are turned on and the others are turned off. In this way, the concentrated infrared LED lighting effectively moves with the trailer end.

[0051] In another example shown in Figure 5, a focused infrared LED 121 includes a motor 70 on the camera arm 116 that moves the beam axis with the trailer end. In the case of a motorized folding camera arm, this can also be achieved by moving the camera arm about a pivot.

[0052] A method 100 for illuminating a commercial vehicle in low light levels is shown in FIG. 7. The controller 30 receives various inputs 50 (block 102), which enable the controller to determine whether and which infrared LEDs are needed. The method 100 includes providing diffused infrared LED light having a first beam angle in a first condition (block 104). The method 100 includes providing focused infrared LED light having a second beam angle that is less than the first beam angle (block 106). Thus, during operation, the diffused infrared LEDs operate in a first condition to provide diffused infrared light to the sides of the commercial vehicle, and the focused infrared LEDs operate in a second condition, different from the first condition, to provide focused infrared light to the ends of the commercial vehicle.

[0053] With respect to hardware architecture, such a computing device may include a processor, memory, and one or more input / output (I / O) device interfaces communicatively coupled via a local interface. The local interface may include, for example, but is not limited to, one or more buses and / or other wired or wireless connections. The local interface may also include additional elements, such as controllers, buffers (caches), drivers, repeaters, and receivers that enable communication, which are omitted for simplicity. Additionally, the local interface may include address, control, and / or data connections to enable appropriate communication between the aforementioned components.

[0054] The controller 30 may be a hardware device for executing software, particularly software stored in a memory, and may be a custom or commercially available processor, a central processing unit (CPU), an auxiliary processor among several processors associated with the controller, a semiconductor-based microprocessor (in the form of a microchip or chipset), or any device for general-purposely executing software instructions.

[0055] The memory may include any one or combination of volatile memory elements (e.g., random access memory (RAM, such as DRAM, SRAM, SDRAM, VRAM, etc.)) and / or non-volatile memory elements (e.g., ROM, hard drive, tape, CD-ROM, etc.). Furthermore, the memory may incorporate electronic, magnetic, optical, and / or other types of storage media. The memory may have a distributed architecture where various components are located remotely from each other but are accessible by the processor.

[0056] Software in memory may include one or more separate programs, each containing an ordered list of executable instructions for implementing a logical function. A system component embodied as software may be constructed as a source program, an executable program (physical code), a script, or any other entity containing a set of instructions to be executed. If constructed as a source program, the program is translated via a compiler, assembler, interpreter, etc., which may or may not be contained in memory.

[0057] Input / output devices of the present disclosure that may be coupled to the system I / O interface(s) may include, but are not limited to, input devices such as a keyboard, mouse, scanner, microphone, camera, mobile device, proximity device, etc. They may also include, but are not limited to, output devices such as a printer, display, etc. Finally, input / output devices may further include devices that communicate as both input and output, such as, but are not limited to, a modulator / demodulator (i.e., for accessing another device, system, or network), a radio frequency (RF) or other transceiver, a telephone interface, a bridge, a router, etc.

[0058] When controller 30 is in operation, the processor may be configured to execute software stored in the memory, communicate data to and from the memory, and generally control the operation of the computing device in accordance with the software. The software in the memory is read, in whole or in part, by the processor and often buffered within the processor before being executed.

[0059] The disclosed CMS 15 provides separate infrared LEDs located at the outer end of the CMS suitable for illuminating the end of the trailer during nighttime docking.
