Description

[Technical Field]

[0001] The present invention relates to the field of lighting systems for vehicles, and more particularly to the management of control image data for pixelated lighting sources in automobiles. [Background technology]

[0002] Current automotive lighting systems, for example, include light sources capable of projecting high-definition light beams. The desired projection of high-definition light can be obtained from an image or image pattern received by the light source, using the light source to display an image or image pattern and thus project a given light beam. These images or image patterns can reach very high resolution, depending in particular on the resolution of the light source used. As an example, the light source can have at least 4,000 to 30,000 pixels, thereby generating a light beam from an image with this level of resolution.

[0003] To achieve the generation of such high-definition light beams, multiple light sources may be used or even combined, which requires controlling multiple light sources and precisely synchronizing these sources to provide controlled, diverse, and adaptable lighting functionality.

[0004] To project these light beams based on image data, various types of light sources are known to be used. For example, this includes monolithic technology, whereby a large number of elementary light sources of the light-emitting diode (LED) type, equivalent to the number of pixels, are etched into a common semiconductor substrate. A combination of electrical connections allows the pixels to be activated independently of each other. Another known technology is microLED technology, which creates a matrix of small LEDs, typically less than 150 μm in size. Micromirror-type modules (DMDs, "Digital Micromirror Devices") also exist, which involve projection technologies that use intensity modulators for a uniform beam. Micromirrors, whose position is controlled by piezoelectric elements, are oriented to selectively reflect the incoming light beam, so that each micromirror corresponds to an elementary light source for the pixel matrix thus created. Light from the light sources is guided onto the micromirror matrix by optical components.

[0005] However, these various types of techniques involve proximity between light sources, which generates interference (also called crosstalk) due to the elementary beams emitted by adjacent light sources. It has been observed that the light intensity of a pixel possibly emitted by one of the light sources does not correspond to the setpoint value associated with this light source. Specifically, only a portion of the elementary beam emitted by this light source is used to create the pixel, and portions of the elementary beams emitted by adjacent light sources are also added to it. The resulting light intensity therefore differs from the expected setpoint value, which makes it complex and unreliable to control the lighting module to emit a pixelated beam that matches that of the digital image provided to the controller.

[0006] The light emitted by the matrix light source further passes through an optical system, typically including at least one optical lens, to project a desired contour in front of the vehicle. However, for a given matrix light source and its associated output optics, the response of the matrix's elementary light sources through the optics is not uniform. Typically, the central region can be projected with high resolution, but the resolution gradually decreases toward the edges of the light source's field of view, which may also have a large aperture of approximately 35°. Therefore, it is difficult to project an accurate contour into a low-resolution region (i.e., at the edge of the field of view). Projecting a clear contour or pattern into such a region typically results in a blurred contour or pattern.

[0007] It has been proposed that optical and / or light aberrations be compensated for upstream of projection by modifying image data after the aberration-generating projection so that the projected image closely resembles the original control image. Once the projection characteristics of the light source and its associated optical device are known, these optical and light characteristics can then be used to automatically pre-compensate for distortions and non-uniformities. However, as the number of light sources and the number of pixels per light source tend to increase, the computational burden to perform this pre-compensation becomes increasingly heavy. This proves problematic for the reliable use of high-definition projectors, particularly in conjunction with the existing electronic architectures of different types of automobiles, whose generating control systems do not necessarily have the necessary computational resources.

[0008] Therefore, automobiles are increasingly equipped with a growing number of light sources that use increasingly heavy high-definition image data, which requires a large amount of data to be managed by the automobile's control system and communicated via a transmission medium between the control system and one or more light sources. For this purpose, data buses, such as the CAN (Car Area Network) protocol, are often used to transport such data between the control system and the light source. However, these data transmission methods have the disadvantage of being bandwidth-limited and generally unable to exceed speeds of, for example, 2-5 Mbps. As a result, problems can arise with transmitting the large amounts of data required for such high-definition image data over these limited networks. In addition, these networks are also used to communicate other vehicle data, which means that the bandwidth available for high-definition image data can be even lower, for example, limited to 70-90% of the maximum rate possible over the data transmission network.

[0009] As an example, to communicate high-definition image data for projecting a lighting feature with a resolution of 20,000 pixels, the rate required in a CAN-FD type transmission network would typically be 10-12 Mbps. However, such CAN-FD networks are currently limited in practice to 5 Mbps (or even 2 Mbps in most cases). Therefore, there is a need to optimize the data transmitted over these networks, and in particular to compress the communicated data in order to transmit a stream of high-definition image data sufficient to provide one or more associated lighting features while still conforming to the rate and bandwidth constraints of these same networks. Summary of the Invention [Problem to be solved by the invention]

[0010] The object of the present invention is to overcome at least one of the problems presented by the prior art, and more specifically to propose an illumination system capable of reliably projecting a light beam corresponding to image data and capable of being used in a multitude of existing architectures, including heterogeneous transmission channels.

[0028] Further features and advantages of the present invention will be better understood from the description of the embodiments and the drawings. [Brief explanation of the drawings]

[0029] [Figure 1] 1 is a diagram of a preferred embodiment of a lighting system according to the present invention; [Figure 2] 1 is a diagram of a preferred embodiment of a lighting system according to the present invention; [Figure 3] 1 is a diagram of a preferred embodiment of a lighting system according to the present invention; [Figure 4] 1 is a diagram of a preferred embodiment of a lighting system according to the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0030] Unless otherwise specified, technical features described in detail for a given embodiment may be combined with technical features described within the context of other embodiments, which are described by way of example and not by way of limitation.

[0031] The description will focus on those elements of a lighting system for a motor vehicle that are necessary for understanding the invention. Other elements that form part of such a system in a known manner will not be mentioned or described in detail. For example, the power supplies and systems of the various units involved, as well as the heat dissipation means and other supports, are known per se and will not be described explicitly.

[0032] The illustration in Figure 1 shows a schematic representation of a lighting system 100 for a motor vehicle according to a first embodiment of the present invention. The system includes at least one lighting module 130 capable of projecting lighting functions from image data 20. The image is generally provided in the form of a matrix of pixel values, each value corresponding to a degree of brightness produced by a corresponding elementary light source of the lighting module 130. Because the light sources of the lighting module include a large number of pixels (on the order of hundreds to thousands), the image data 20 is large.

[0033] The illumination module 130 includes data receiving means 132, such as a network interface, that allows data to be received via a corresponding data transmission channel. The illumination module 130 can include, for example, pixelated light-emitting diodes or DMD-type micromirror devices, although the invention is not limited to these examples. In a known manner, the illumination module can also include an optical projection system (not shown) through which the light beams generated by the light source pass, and a computer (not shown) that can convert the brightness values ​​stored in the image data 20 into periodic ratios of pulse-width modulation (PWM) type control signals. The corresponding control signals are used in a known manner to control the power supplies for the light source pixels, such that the brightness emitted by the pixels is generally proportional to the average intensity of the current passing through the pixels, which is generally proportional to the PWM duty cycle. This allows the illumination module 130 to project a light beam corresponding to the image data 20. The illumination module is particularly characterized by optical distortion characteristics and brightness non-uniformities, primarily caused by the proximity of the pixels, the optics, or manufacturing defects. These characteristics 15 may be measured during the manufacturing stage of the lighting module or when fitted to the automobile headlamp and stored in a memory element.

[0034] The lighting system 100 further comprises a control unit 120, preferably created by a microcontroller element programmed for this purpose, connected to at least one lighting module 130 by a data transmission channel. For this purpose, the control unit comprises data transmission means 122, such as a network interface, allowing the transmission of image data 20 to the at least one lighting module via the associated data transmission channel. This can be, for example, a CAN or CAN-FD data bus in point-to-point mode, an Ethernet-type connection, or even a high-speed channel of the GMSL (Gigabit Multimedia Serial Link) type. The control unit is configured to generate the image data 20 to be projected by each lighting module 130.

[0035] The control unit 120 generates image data 20 after receiving lighting setpoints 10 received at a network input and originating from a decision-making unit (not shown) inside the vehicle. The lighting setpoints inform the control unit 120 of the lighting functions that must be projected by at least one lighting module 130. The setpoints 10 may include, in particular, one of the following data, but are not limited to these examples: - Low beam (LB), - High beam (HB), - Adaptive Driving Beam (ADB), or - Road Writing (RW).

[0036] Adaptive driving beam (ADB) is understood to mean any lighting function that allows the light beam to be dynamically changed to adapt to the vehicle traffic situation. For example, this can relate to a function in which the lighting is projected with high beam type photometry / imagery while preventing glare for other road users. Alternatively or in addition, the function can relate to the following: - photometry that allows dynamic directional lighting, in other words the horizontal displacement of the maximum intensity of LB or HB photometry according to the rotation angle of the steering wheel of the car (also known as DBL, which stands for Dynamic Bending Light), - lighting that makes it possible to avoid glare from road signs as a result of the projection of light beams from motor vehicles (also known as TSAG, which stands for Traffic Sign Anti-Glare); - Lighting that allows the projection of line-type patterns on the road, in particular to demarcate sections of the road used by vehicles or to suggest obstacle avoidance strategies (also known as LA, for Line Assist).

[0037] Road lighting (RW) is understood to mean any lighting feature that makes it possible to project onto the road patterns visible to the driver and / or road users, in particular, for example, driving aids, information signals or other navigation indicators.

[0038] The control unit 120 preferably includes a memory element (not shown) that stores basic photometry corresponding to each possible setpoint 10. Depending on the received setpoint, a corresponding image is read out in the memory element. Before being transmitted to the illumination module 130, the image data is transformed to take into account the optical and / or light characteristics 15 of the associated illumination module 130. These data may be read out by the illumination module and stored in the control unit upon pairing between the control unit 120 and the illumination module. Alternatively, a permanent connection between the two associated entities may enable access to these data. The control unit 120 uses the characteristics 15 of the illumination module 130 to pre-compensate for light non-uniformities and / or distortions caused by the illumination module's inherent components when projecting any image. For example, if a given pixel of the light source is defective, the brightness of the corresponding adjacent pixel in the image 20 may be increased to compensate for this defect. Furthermore, geometric deformations of the image's edges due to optical lenses may be pre-compensated when generating the image 20. These potentially heavy calculations, given the large number of pixels that could amount to thousands of pixels, do not impact the capacity of the vehicle's existing computer, as they are supported by a control unit 120 dedicated to the lighting module 130.

[0039] In the example shown, the control unit includes a compression unit 121 which compresses the image data 20 generated and intended for the lighting module 130 into compressed image data 20' and then sends said compressed image data via data transmission means 122. Any data compression algorithm can be used by the compression unit 121 to reduce the amount of data and therefore the data rate to be transmitted.

[0040] 1, the lighting module includes a decompression unit 131 configured to decompress the compressed image data 20' into image data 20 depending on the compression algorithm used. Preferably, the compression unit and / or the decompression unit may be created by the same computer / microcontroller as the other computing functions described with reference to the control unit and the lighting module, respectively. Alternatively, the compression unit and / or the decompression unit may be created by a computing core of a microcontroller having multiple computing cores.

[0041] Thus, in the illustrated example, a transmission channel with a low data rate relative to the rate of the image data 20, for example of the CAN-FD type, can connect the control unit 120 to the lighting modules 130. High definition lighting functionality can thus be added to an existing architecture by combining a corresponding lighting module 130 as well as a control unit 120 that acts as an interface between the existing decision-making unit generating the setpoints 10 and the lighting modules 130.

[0042] The illustration in FIG. 2 schematically illustrates a lighting system 200 for a vehicle according to a second embodiment of the present invention. The system includes at least one lighting module 230 capable of projecting lighting functions from image data 20. The image is generally provided in the form of a matrix of pixel values, each value corresponding to a degree of brightness produced by a corresponding elementary light source of the lighting module 230. The lighting module 230 includes data receiving means 232, such as a network interface, that allows data to be received via a corresponding data transmission channel. The lighting module is characterized, in particular, by optical distortion characteristics and brightness non-uniformity caused primarily by pixel proximity (including interference or crosstalk between adjacent pixels), the optical system, or manufacturing defects. These characteristics 15 can be measured and stored in a memory element during the manufacturing phase of the lighting module or when it is installed in the vehicle headlamp. The lighting system 200 further includes a control unit 220, preferably generated by a microcontroller element programmed for this purpose and connected to the at least one lighting module 230 via a data transmission channel. For this purpose, the control unit 220 includes data transmission means 232, such as a network interface, that allows image data to be transmitted to at least one lighting module via an associated data transmission channel. The control unit 220 generates image data 20 after receiving lighting setpoints 10, which are received at a network input and originate from a decision-making unit 210 that forms part of the system 200. The lighting system 200 is functionally equivalent to the lighting system 100 described with reference to FIG. 1. However, it incorporates a decision-making unit 210 that is programmed to select setpoints by interpreting input signals 5 provided by a vehicle sensor, such as a camera. For example, if the camera detects a road sign, the decision-making unit 210 decides to provide a TSAG-type setpoint. The control unit 220 generates photometric / corresponding image data 20 by pre-correcting them for the optical / luminance characteristics 15 of the lighting module 230.

[0043] In the illustrated example, the control unit 220 is connected by an electrical connection to the compression unit 221, which compresses the image data 20 generated and intended for the lighting module 230 into compressed image data 20' and then sends the compressed image data via the data transmission means 222 of the control unit 220. Any data compression algorithm can be used by the compression unit 221 to reduce the amount of data and therefore the data rate to be transmitted. The use of a dedicated microcontroller to create the compression unit 221 allows the control unit 220 to be relieved of the additional computational load required for the data compression task. Needless to say, the compression architecture of FIG. 1 can alternatively be contemplated in this embodiment without still departing from the scope of the present invention.

[0044] Still in the example shown in Figure 2, the lighting module includes a decompression unit 231, which is configured to decompress the compressed image data 20' into image data 20 depending on the compression algorithm used. The use of a dedicated microcontroller to create the decompression unit 231 allows the control unit 230 to be relieved of the additional computational burden required for the data compression task. Of course, as an alternative, the compression architecture of Figure 1 may also be contemplated in this embodiment without still departing from the scope of the present invention.

[0045] Thus, in the illustrated example, a transmission channel with a low data rate relative to the rate of the image data 20, for example of the CAN-FD type, can connect the control unit 220 to the lighting module 230. High definition lighting functionality can thus be added to an existing architecture by combining a corresponding lighting module 230 as well as a control unit 220 that acts as an interface between the existing decision-making unit generating the setpoints 10 and the lighting module 230.

[0046] The illustration in FIG. 3 schematically illustrates a lighting system 300 for a vehicle according to a third embodiment of the present invention. The system includes at least one lighting module 330 capable of projecting lighting functions from image data 20. The image is generally provided in the form of a matrix of pixel values, each value corresponding to a degree of brightness produced by a corresponding elementary light source of the lighting module 330. The lighting module 330 includes data receiving means 332, such as a network interface, that allows data to be received via a corresponding data transmission channel. The lighting module is characterized, in particular, by optical distortion characteristics and brightness non-uniformity caused primarily by pixel proximity (including interference or crosstalk between adjacent pixels), the optical system, or manufacturing defects. These characteristics 15 can be measured and stored in a memory element during the lighting module's manufacturing phase or upon installation in the vehicle headlamp. The lighting system 300 further includes a control unit 320, preferably generated by a microcontroller element programmed for this purpose and connected to the at least one lighting module 330 via a data transmission channel. For this purpose, the control unit comprises data transmission means 322, such as a network interface, which allows transmitting image data to at least one lighting module via an associated data transmission channel. The control unit 320 generates image data 20 after receiving lighting setpoints 10 received at a network input and originating from a decision-making unit (not shown). The lighting system 300 is functionally equivalent to the lighting system 100 described with reference to FIG. 1.

[0047] In the illustrated example, the control unit 320 includes data transmission means 322 that allows connection to a high-data-rate first data transmission channel CH, e.g., a GMSL-type channel. However, the lighting module 330 includes data reception means 332 that only allows connection to a more limited-data-rate second data transmission channel CL, e.g., a CAN or CAN-FD-type channel. The first channel CH connects the data transmission means of the control unit 320 to a dedicated intervening compression unit 321, which compresses the image data 20 generated and transmitted by the control unit 320 into compressed image data 20'. The compressed image data 20' is then relayed to the lighting module 330 via a second channel of type CL. Any data compression algorithm can be used by the compression unit 321 to reduce the amount of data, and therefore the data rate, to be transmitted. The compression unit 321 preferably includes a microcontroller element for compressing the data, a first network interface for receiving data via the CH-type channel, and a second network interface for transmitting data via the CL-type channel.

[0048] Still in the example shown in Figure 3, the lighting module includes a decompression unit 331 configured to decompress the compressed image data 20' into image data 20 depending on the compression algorithm used. Preferably, the decompression unit may be produced by the same computer / microcontroller as the other computational functions described with reference to the lighting module. Of course, alternatively, the compression architecture of Figure 2 may also be contemplated in this embodiment without still departing from the scope of the present invention. This embodiment allows high-resolution lighting functions to be performed by components with heterogeneous network interfaces within the same vehicle.

[0049] The illustration in FIG. 4 schematically illustrates a lighting system 400 for a vehicle according to a fourth embodiment of the present invention. The system includes at least one lighting module 430 capable of projecting lighting functions from image data 20. The image is generally provided in the form of a matrix of pixel values, each value corresponding to a degree of brightness produced by a corresponding elementary light source of the lighting module 430. The lighting module 430 includes data receiving means 432, such as a network interface, that allows data to be received via a corresponding data transmission channel. The lighting module is characterized, in particular, by optical distortion characteristics and brightness non-uniformity caused primarily by pixel proximity (including interference or crosstalk between adjacent pixels), by the optical system, or by manufacturing defects. These characteristics 15 can be measured and stored in a memory element during the manufacturing phase of the lighting module or when it is installed in the vehicle headlamp. The lighting system 400 further includes a control unit 420, preferably generated by a microcontroller element programmed for this purpose and connected to the at least one lighting module 430 via a data transmission channel. For this purpose, the control unit comprises data transmission means 422, such as a network interface, which allows transmitting image data to at least one lighting module via an associated data transmission channel. The control unit 420 generates image data 20 after receiving lighting setpoints 10 received at a network input and originating from a decision-making unit (not shown). The lighting system 400 is functionally equivalent to the lighting system 100 described with reference to FIG. 1.

[0050] In the illustrated example, the control unit 420 includes data transmission means 422 that allow connection to a first data transmission channel CL of limited data rate, e.g., a CAN or CAN-FD type channel. However, the lighting module 430 includes data reception means 432 that only allow connection to a second data transmission channel CH of higher data rate, e.g., a GMSL type channel. The control unit thus includes a compression unit 421 that compresses the generated image data 20 into compressed image data 20' and then transmits the compressed image data via the first channel CL. Of course, alternative compression architectures to those of FIG. 2 may also be contemplated without departing from the scope of the present invention. The first channel CL connects the data transmission means of the control unit 420 to a dedicated intervening decompression unit 431, which decompresses the compressed image data 20' transmitted by the control unit into decompressed image data 20. The decompressed image data 20 is then relayed to the lighting module 430 via a second channel CH type. Any data compression algorithm can be used by the compression unit 421 to reduce the amount of data and therefore the data rate to be transmitted. The decompression unit 431 preferably includes a microcontroller element for decompressing the data, a first network interface for receiving data over a CL type channel, and a second network interface for transmitting data over a CH type channel. This embodiment allows high-resolution lighting functions to be performed by components with heterogeneous network interfaces within the same vehicle.

[0051] Throughout all described embodiments, the decision-making unit 210 shown in FIG. 2 may be connected to other lighting units (not shown) using non-pixelated, limited pixelated, or segmented illumination sources. These lighting units do not require additional calculations performed by the control unit as described in the embodiments of the present invention. These lighting units may be directly controlled by setpoints originating from the decision-making unit, such as, for example, turn signal illumination, TI, etc.

[0052] Needless to say, the described embodiments do not limit the scope of protection of the present invention. Using the description provided above, other embodiments can still be contemplated without departing from the scope of the present invention.
