Description

Technical Field

[0001] This invention relates to the field of automotive technology, and in particular to a driving light change assist system and an automobile. Background Technology

[0002] When driving, a sudden and significant change in ambient light can easily cause drivers to experience temporary dimming or blurred vision. For example, when entering a tunnel during the day, drivers experience a "dark adaptation" phenomenon where their vision suddenly goes black. Conversely, when exiting the tunnel, drivers experience a "light adaptation" phenomenon where they are momentarily blinded by bright light, resulting in temporary blurred vision and glare. This may cause drivers to unconsciously squint or close their eyes. These situations occur because the human eye needs time to adapt to changes in light intensity, posing a threat to driving safety.

Based on the supplementary light intensity, a first control command is generated; the first control command is used to control the first light-emitting unit to emit light at the supplementary light intensity. The first control command is sent to the first light-emitting unit.

[0008] Furthermore, the optical sensing module includes an image sensing unit; the field of view of the image sensing unit is the same as that of the driver of the car. The detection result of the optical sensing module is the environmental image in front of the car captured by the image sensing unit.

[0009] Furthermore, the supplementary lighting module includes; Sweeper unit; the sweeper unit is used to sweep on the outer side of the windshield; Motor unit; the motor unit is used to drive the scraper unit to perform repeated back-and-forth sweeping motions and to return the angle and position information of the scraper unit in real time; The second light-emitting unit is installed on the side of the wiper unit facing the windshield.

[0010] Further, the step of controlling the light emission of the supplementary lighting module based on the detection results of the optical sensing module includes: Obtain the regional mapping relationship between the environmental image and the windshield; The environmental image is identified to determine the dark areas in the environmental image; Based on the region mapping relationship, the dark region is mapped onto the windshield to determine the target region in the windshield; Based on the target area, a first travel interval and a second travel interval of the motor unit are determined; the first travel interval is the travel interval when the motor unit drives the scraper unit to sweep through the target area, and the second travel interval is the travel interval other than the first travel interval among all the travel intervals of the motor unit; Send a drive control command to the motor unit to trigger the motor unit to drive the scraper unit to sweep, and receive the angle position information returned by the motor unit in real time; When the angular position information corresponds to the first travel interval, a light emission control command is generated and sent to the second light emission unit; the light emission control command is used to control the second light emission unit to emit light at the supplementary light intensity; When the angular position information corresponds to the second travel interval, a shutdown control command is generated and sent to the second light-emitting unit; the shutdown control command is used to control the second light-emitting unit to stop emitting light.

[0011] Further, the step of identifying the dark areas in the environmental image includes: The environmental image is identified to determine the brightest area in the environmental image; Detect the brightness of the brightest area; Obtain the brightness range of the optical sensing module; The position of the brightness of the brightest region in the brightness range is obtained, and the symmetrical position relative to the midpoint of the brightness range is determined as the brightness threshold.

This assists the driver in adapting to changes in light during driving, ensuring driving safety. Furthermore, the supplementary lighting module is installed on the outside of the car's windshield, ensuring that the light emitted by the module, like the ambient light, passes through the windshield and illuminates the cabin. This ensures that both types of light are affected by the windshield in the same way, retaining only changes in light intensity, thus enabling the driving light change assistance adaptation system to reduce the impact of light changes and minimize discomfort caused by the difference between the two types of light.

[0016] This embodiment provides a driving light change assist adaptation system. (Refer to...) Figure 1 The driver's light change assist system includes an optical sensing module, a supplemental lighting module, and a control module. The control module is a component with functions such as data acquisition, data processing and output, and control; for example, an electronic control unit (ECU) can be used as the control module.

[0017] In this embodiment, the first form of the optical sensing module is a light intensity sensing unit, meaning a light intensity sensing unit can be used as the optical sensing module. Similarly, the first form of the supplementary lighting module is multiple first light-emitting units, meaning multiple first light-emitting units can be used as the supplementary lighting module. Specifically, LEDs with corresponding driving circuits can be used to form the first light-emitting units. (Refer to...) Figure 2When multiple first light-emitting units are installed, they can be arranged around the windshield, specifically mounted on the A-pillars, the upper edge, and the lower edge of the windshield. Specifically, each first light-emitting unit is installed on the outer side of the windshield, that is, the side facing outwards. The light emission direction of each unit is towards the windshield, allowing the light to pass through the windshield and reach the inner side of the passenger compartment, where it can be observed by the driver. The light emission direction of the first light-emitting units can be perpendicular to the windshield or at an angle not parallel to the windshield surface. The refraction effect of the windshield ensures that at least a portion of the light emitted by the first light-emitting units reaches the driver's eyes, providing an enhanced supplemental lighting effect beyond the ambient light. The first light-emitting units themselves do not obstruct the driver's view, ensuring driving safety.

[0018] In this embodiment, the optical sensing module (light intensity sensing unit) can be installed in a location such as the front grille of the vehicle. The receptive field of the optical sensing module (light intensity sensing unit) is configured to be the same as or wider than the driver's field of vision. By configuring the optical sensing module (light intensity sensing unit), it can detect light with specific wavelengths, color temperatures, etc. (e.g., direct sunlight, sunlight scattered through clouds), while filtering out red light emitted by the vehicle's taillights, etc. In other words, the detection results of the optical sensing module (light intensity sensing unit) may not include the influence of the vehicle's taillights, etc.

[0019] In this embodiment, the optical sensing module (light intensity sensing unit) detects the light intensity in front of the vehicle at each sampling moment. The optical sensing module (light intensity sensing unit) can calculate the difference between the light intensity at any given moment and the light intensity at the previous moment, divide this difference by the duration between the two moments, and thus obtain the ambient light change rate at that moment. In other words, the ambient light change rate represents how quickly the light intensity changes at any given moment; the larger the absolute value of the ambient light change rate, the faster the light intensity changes.

[0020] In this embodiment, when the supplementary lighting module emits light, it illuminates the windshield not only by sunlight and streetlights but also by the light emitted by the supplementary lighting module, thereby achieving a superimposed illumination supplementary lighting effect. This allows the driver to see a brighter visual effect when observing the windshield while driving.

[0021] In this embodiment, the control module controls the light emission of the supplementary lighting module based on the detection results of the optical sensing module. Specifically, the control module executes the following steps: S1A. Determine the first light-emitting unit to be controlled and the corresponding supplementary light intensity based on the rate of change of ambient light; S2A. Generate the first control command based on the supplementary light intensity; S3A. Send the first control command to the first light-emitting unit.

[0022] Steps S1A-S3A represent the first execution mode of the control module, i.e., applied to... Figure 2 The execution method of the first type of supplementary lighting module shown.

[0023] In step S1A, the optical sensing module (light intensity sensing unit) sends the detected ambient light change rate (which can retain its sign, where a positive ambient light change rate indicates that the ambient light intensity changes from weak to strong, and a negative ambient light change rate indicates that the ambient light intensity changes from strong to weak) to the control module. The control module can set a fixed positive conversion coefficient k and calculate the product of the ambient light change rate and the conversion coefficient k to obtain the supplementary light intensity. The control module can also set a fixed conversion threshold and compare the absolute value of the ambient light change rate with the conversion threshold. If the absolute value of the ambient light change rate is greater than the conversion threshold, then the supplementary light intensity is set to a fixed value; otherwise, if the absolute value of the ambient light change rate is less than or equal to the conversion threshold, then the supplementary light intensity is set to zero. In this embodiment, the supplementary light intensity is the intensity of the light emitted by the first light-emitting unit, and its unit can be candela (Cd). Specifically, it can be the luminous intensity of a single first light-emitting unit or the sum of the luminous intensities of all first light-emitting units.

[0024] In step S1A, the calculated supplementary light intensity is positively correlated with the rate of change of ambient light; that is, the greater the absolute value of the rate of change of ambient light, the greater the supplementary light intensity. For example, when a car is driving in a tunnel, the ambient light emitted from the front mainly includes the headlights of the car in front, the streetlights installed in the tunnel, and the sunlight scattered from the sky entering from the tunnel entrance. The optical sensing module (light intensity sensing unit) can filter out the influence of the headlights of the car in front and the streetlights installed in the tunnel, so that the rate of change of ambient light detected by the optical sensing module (light intensity sensing unit) is mainly the rate of change of intensity of sunlight entering from the tunnel entrance. As the car moves from the tunnel entrance to the tunnel entrance, in the absence of a car in front (if there is a car in front, the driver can adopt a following strategy to reduce the impact of sudden changes in light, which is relatively safe), the light intensity detected by the optical sensing module (light intensity sensing unit) continuously increases. Therefore, the rate of change of ambient light is a stable positive value or a continuously increasing value. Therefore, when a car is driving towards the tunnel entrance in a tunnel, the control module can determine a positive supplementary light intensity by executing step S1A.

[0025] In step S1A, the control module can determine all first light-emitting units as the first light-emitting units to be controlled if a positive supplementary light intensity is calculated.

[0026] In step S2A, a first control command is generated based on the supplementary light intensity calculated in step S1A. The content of the first control command is to control the first light-emitting unit to emit light according to the supplementary light intensity calculated in step S1A.

[0027] In step S3A, the control module sends the first control command generated in step S2A to the first light-emitting unit, so that the first light-emitting unit emits light according to the supplementary light intensity calculated in step S1A.

[0028] In this embodiment, the control module continuously executes steps S1A-S3A in a loop. Since the processing speed of the control module is fast enough, each execution of steps S1A-S3A by the control module can be considered as simultaneous, thereby controlling the luminous intensity of the first light-emitting unit, i.e., the supplementary light intensity, to keep it in sync with the rate of change of ambient light. Thus, when driving in an open environment (excluding tunnels), the rate of change in ambient light detected in step S1A is zero or very small. Therefore, the supplementary light intensity calculated in step S1A is zero or very small, and the first light-emitting unit will not be controlled to emit light in step S3A. However, when driving in a closed environment such as a tunnel, the rate of change in ambient light is larger as the car approaches the tunnel entrance. Therefore, step S1A calculates a positive supplementary light intensity, and the first light-emitting unit is controlled to emit light in step S3A. This allows the driver to observe the light emitted by the first light-emitting unit before reaching the tunnel entrance. Compared to not using the driving light change adaptation system, this provides a brighter visual effect for the driver, allowing them to adapt to the brighter environment in advance. This reduces the visual impact of the sudden increase in light when the driver reaches the tunnel entrance, reducing blurred vision and glare. Consequently, the driver can observe the external road environment more clearly at the tunnel entrance, making faster and more accurate driving decisions and ensuring traffic safety.

[0029] In this embodiment, the second form of the optical sensing module is an image sensing unit, that is, an image sensing unit can be used as an optical sensing module. Specifically, the image sensing unit is a visible light camera. Meanwhile, the second form of the supplementary lighting module is a wiper unit, multiple second light-emitting units mounted on the wiper unit, and a motor unit for driving the wiper unit.

[0030] In this embodiment, the structure of the second form of the supplementary lighting module is as follows: Figure 3 As shown. (Refer to...) Figure 3The wiper unit is made of materials such as rubber. The motor unit drives the wiper unit to repeatedly sweep back and forth along the outer surface of the windshield. For example, when the motor unit drives the wiper unit to sweep upwards to the upper stop point (e.g., the far left of the windshield from the driver's perspective), it then drives the wiper unit to sweep downwards to the lower stop point (e.g., the lower edge of the windshield), and then drives the wiper unit to sweep upwards to the upper stop point again, and so on. The motor unit can specifically be a stepper motor, which can detect the angular position information of the wiper unit while driving it to sweep. The angular position information can represent the angle between the wiper unit and a specific direction (e.g., the lower edge of the windshield), and return the angular position information to the control module in real time.

[0031] In this embodiment, the wiper module installed on the vehicle can be reused, with the wiper blade of the wiper module serving as the wiper blade unit of the supplementary lighting module, and the wiper module's motor serving as the motor unit of the supplementary lighting module. This simplifies the required hardware structure and space occupation. In this embodiment, additional wiper blade units and motor units can be added to the existing wiper module installed on the vehicle. That is, dedicated wiper blade units and motor units are used as components in the supplementary lighting module, instead of reusing components from the wiper module. When using dedicated wiper blade units, a certain gap can be maintained between the wiper blade unit and the surface of the windshield; that is, the wiper blade unit does not fit tightly against the surface of the windshield. Regardless of the form of the supplementary lighting module, its working principle is the same; therefore, the supplementary lighting module can be explained using the reuse of components from the wiper module as an example.

[0032] In this embodiment, an LED with a corresponding driving circuit can be used to form a second light-emitting unit. (Refer to...) Figure 3 Each of the second light-emitting units can be arranged along the length of the wiper unit. Specifically, each of the second light-emitting units is installed on the side of the wiper unit facing the windshield, so that the light emission direction of each of the second light-emitting units is towards the windshield. This allows the light to pass through the windshield and reach the inside of the windshield, i.e., the passenger compartment, when the second light-emitting unit emits light, so that it can be observed by the driver.

[0033] In this embodiment, the optical sensing module (image sensing unit) can be installed in a position such as the front grille or the rearview mirror. The receptive field of the optical sensing module (image sensing unit) is configured to be the same as or wider than the driver's field of vision, so that the image captured by the optical sensing module (image sensing unit), i.e., the environmental image in front of the car, can be cropped to obtain the situation seen from the driver's perspective.

[0034] When the optical sensing module (image sensing unit) is installed in a location such as the rearview mirror, it can be prevented from capturing images of the second light-emitting unit. A field-of-view adjustment module can also be included. Specifically, the field-of-view adjustment module includes components such as an eye-tracking device and a drive motor. The eye-tracking device detects the driver's eye direction to determine the driver's field of vision, and the drive motor drives the image sensing unit to maintain real-time synchronization with the driver's field of vision.

[0035] In this embodiment, Figure 3 The second type of supplemental lighting module shown, after being installed in a car, produces the following effect: Figure 4 As shown. Figure 4 In the image, a car is traveling inside a tunnel towards the tunnel entrance, showing the environment the driver can observe (including structures such as the tunnel walls and entrance). As the car continues to move closer to the entrance, the driver's perspective changes, and the environment the driver can observe changes as follows: Figure 5 As shown. Because the receptive field of the optical sensing module (image sensing unit) is configured to be the same as the driver's field of vision, the content of the environmental image captured by the optical sensing module (image sensing unit) is the same as... Figure 4 and Figure 5 The external environment is the same.

[0036] In this embodiment, the control module controls the light emission of the supplementary lighting module based on the detection results of the optical sensing module. Specifically, the control module executes the following steps: S1B. Obtain the region mapping relationship between the environmental image and the windshield; S2B. Recognize the environmental image and identify the dark areas in the environmental image; S3B. Based on the region mapping relationship, map the dark region onto the windshield to determine the target region in the windshield; S4B. Determine the first and second stroke intervals of the motor unit based on the target area; S5B. Sends drive control commands to the motor unit to trigger the motor unit to drive the scraper unit to sweep, and receives the angle and position information returned by the motor unit in real time. S6B. When the angle position information corresponds to the first travel interval, generate a light-emitting control command and send the light-emitting control command to the second light-emitting unit; S7B. When the angle position information corresponds to the second travel interval, a shutdown control command is generated and sent to the second light-emitting unit.

[0037] Steps S1B-S7B represent the second execution mode of the control module, i.e., applied to... Figure 3The second type of supplementary lighting module is shown in the following diagram.

[0038] As the car continues to move, the optical sensing module (image sensing unit) will acquire multiple environmental images. The content of each environmental image is different. Therefore, the processing of environmental images is a dynamic process. In this embodiment, the processing of one environmental image is used as an example to explain steps S1B-S7B.

[0039] In step S1B, refer to Figure 6 Since the receptive field of the optical sensing module (image sensing unit) corresponds to the driver's field of vision, and the driver's line of sight passes through the windshield, there is a regional mapping relationship between the receptive field of the optical sensing module (image sensing unit) and the windshield. That is, a specific area in the environmental image captured by the optical sensing module (image sensing unit) corresponds to a specific area in the windshield. In other words, there is a one-to-one mapping relationship between each area in the optical sensing module (image sensing unit) and each area in the windshield.

[0040] In step S2B, refer to Figure 6 A fixed grid can be used to divide the environmental image into multiple regions. Based on the region mapping relationship in step S1B, each grid, i.e., each region in the environmental image, can be mapped to a region on the windshield. Next, the control module identifies the brightness of each region, determines the region with the highest brightness (i.e., the brightest region), and records the luminance of the brightest region. peak Specifically, the luminance of the brightest area. peak It is the brightness range (e.g., 0-luminance) of the optical sensing module (image sensing unit). max One of the values ​​in ), i.e., 0 < luminance peak ≤luminance max Next, the control module determines the luminance of the brightest area. peak Is it greater than the midpoint of the luminance range? middle (i.e., luminance) middle =luminance max / 2), if luminance peak Luminance less than or equal to the midpoint of the luminance range middle Then, determine the luminance of the brightest area. peakIf the luminance is low, meaning even the brightest areas of the environmental image are not bright enough for the driver's visual perception, then subsequent steps such as S2B-S7B can be skipped for the currently detected environmental image; if the luminance is low... peak Luminance greater than the midpoint of the luminance range middle Then we can continue with the next steps, specifically, calculating the luminance range 0-luminance. max In the middle, the luminance of the brightest area peak luminance relative to the midpoint of the luminance range middle The luminance value corresponding to the symmetrical position threshold ,Right now luminance threshold =luminance middle - (luminance) peak -luminance middle ) =2luminance middle -luminance peak With this luminance value threshold As a brightness threshold. For Figure 6 In the environmental image shown, the brightness of each region is obtained, and regions with brightness values ​​lower than the luminance value are excluded. threshold The area was identified as the dark area.

[0041] After determining the dark areas in step S2B, step S3B is executed to map the brightest and darkest areas onto the windshield based on the area mapping relationship determined in step S1B. For example, the mapping result in this embodiment is as follows: Figure 7 As shown.

[0042] In step S3B, the target area can be determined by combining all the dark areas in the windshield; alternatively, the target area can be determined by combining all the dark areas and the brightest area in the windshield.

[0043] In step S4B, the first and second stroke intervals of the motor unit are determined based on the target area. In this embodiment, when the motor unit drives the scraper unit, the stroke interval during which the scraper unit sweeps through the target area is determined as the first stroke interval. For example, referring to... Figure 7 The interval between the two red dotted lines is defined as the first travel interval; the travel intervals of the motor unit other than the first travel interval are defined as the second travel interval, for example, referring to... Figure 7The interval above the upper red dashed line and the interval below the lower red dashed line are defined as the second travel interval.

[0044] In step S5B, the control module sends a drive control command to the motor unit, thereby controlling the motor unit to drive the scraper unit to sweep, and receives the angle position information returned by the motor unit in real time. Based on the angle position information, the control module determines whether the scraper unit has currently swept to the first stroke range or the second stroke range.

[0045] If, during step S5B, the control module determines that the scraper unit has currently swept to the first stroke range, then the control module executes step S6B, generates a light emission control command, and sends the light emission control command to the second light emission unit, thereby controlling the second light emission unit to emit light with supplementary light intensity. The control module can set the supplementary light intensity to the luminance of the brightest area. peak A positive correlation exists, meaning that the brighter the brightest area in the currently captured environmental image, the greater the luminous intensity of the second light-emitting unit, allowing the driver to observe a brighter supplemental lighting effect. Specifically, the effect of executing step S6B is as follows: Figure 7 As shown, the scraper module that sweeps into the first stroke range drives the second light-emitting unit into the first stroke range as well, and drives the second light-emitting unit to emit light. The light emitted by the second light-emitting unit coincides with the dark area in the ambient image, thereby providing supplementary light to the dark area.

[0046] If, during step S5B, the control module determines that the scraper unit has currently swept to the second stroke range, then the control module executes step S7B, generates a shutdown control command, and sends the shutdown control command to the second light-emitting unit, thereby controlling the second light-emitting unit to stop emitting light. Specifically, the effect of executing step S7B is as follows: Figure 8 As shown, the scraper module that sweeps into the second stroke range drives the second light-emitting unit into the second stroke range as well, and drives the second light-emitting unit to stop emitting light. The second light-emitting unit no longer provides supplementary lighting, and the driver can only observe the light shining in from the external environment.

[0047] In this embodiment, steps S1B-S7B are executed dynamically, meaning the control module continuously executes steps S1B-S7B in a loop. Because the optical sensing module (image sensing unit) continuously captures new environmental images, the environmental images processed each time steps S1B-S7B are executed are different. Figure 7 and Figure 8 The distribution of the brightest and darkest areas in the image is also different.

[0048] In this embodiment, the principle of executing steps S1B-S7B is as follows: by executing step S2B, the luminance of the brightest area in the environmental image can be improved.peak Sufficiently high (e.g., greater than the midpoint of the luminance range) middle In the case of ), the luminance of the brightest area peak The lower the threshold, the darker the brightest area, and thus the higher the brightness threshold is set. This results in more areas of the environment image being identified as dark areas. Conversely, the brighter the brightest area, the fewer areas of the environment image are identified as dark areas. This method of determining the number of dark areas matches the change in light intensity before a driver encounters a sudden change in light (e.g., exiting a tunnel). For example, the brightest area (corresponding to the tunnel entrance observed from inside the tunnel) tends to become increasingly bright, thus initially identifying more areas as dark areas. Based on this, when steps S3B-S7B are executed, a larger first travel interval is obtained. This allows the second light-emitting unit to emit light over a larger range and for a longer duration when sweeping into the first travel interval, i.e., the dark area. This enables the driver to observe not only the ambient light but also the light emitted by the second light-emitting unit while still a considerable distance from the tunnel entrance. The system adapts to environments with enhanced light intensity. As the driver approaches the tunnel entrance, the first travel interval dynamically decreases, causing the second light-emitting unit to emit light for a shorter duration. At this time, the area and brightness of the brightest region also increase, keeping the total light intensity observed by the driver stable. Therefore, by executing steps S1B-S7B, when the driver is in a closed environment such as a tunnel, the second light-emitting unit can supplement the light intensity observed by the driver at a certain distance from the tunnel entrance, thus maintaining the stability of the total light intensity observed by the driver during driving. On the other hand, the second light-emitting unit mainly supplements the light in dark areas, ensuring that the light intensity of each area in the driver's field of vision is uniform at each instant. The above-mentioned treatment of stabilizing and uniformizing light intensity helps to reduce the impact of sudden changes in light intensity faced by the driver when leaving a closed environment such as a tunnel, thereby ensuring driving safety.
