Abstract
Description
Technical Field
[0001] This invention relates to the field of vehicle control technology, and in particular to a method, device, equipment, and program product for controlling vehicle lights for pets. Background Technology
[0002] Current vehicle light signal triggering schemes mainly target vehicles and pedestrians, and can be roughly divided into two categories: The first category is a general obstacle triggering scheme, such as the reversing radar system of traditional vehicles, which only detects obstacles at close range and triggers warning lights (such as 2Hz fast flashing), without distinguishing between pets and other objects. The fast flashing lights can easily frighten pets and cause traffic accidents. The second category is a pedestrian recognition and association scheme, which triggers light reminders after recognizing pedestrians through cameras. It cannot recognize pets and is not adapted to the visual characteristics of pets. Similarly, it cannot prevent pets from being frightened in advance, which poses a safety hazard.
[0003] The above problems urgently need to be addressed. Summary of the Invention
[0004] The purpose of this invention is to at least partially solve one of the technical problems existing in the prior art.
[0005] Therefore, one objective of this invention is to provide a vehicle light signal control method for pets. This method identifies the pet's pet type, distance from the vehicle, and relative movement trend. It determines the light signal trigger distance based on the vehicle's operating conditions to determine whether to trigger the pet light signal. The method also adaptively adjusts the flashing frequency, brightness, and color of the pet light signal to effectively remind the pet while avoiding startling it, thereby improving vehicle driving safety.
[0006] Another objective of this invention is to provide a vehicle light signal control device for pets.
[0007] To achieve the above-mentioned technical objectives, the technical solutions adopted in the embodiments of the present invention include: On one hand, embodiments of the present invention provide a vehicle light signal control method for pets, including the following steps: Acquire the target vehicle's current vehicle operating condition, current ambient light intensity, and environmental image information; The target pet's pet type, current distance, and relative movement trend between the target pet and the target vehicle are identified based on the environmental image information. The light signal trigger distance is determined based on the current vehicle operating condition and the pet type, and whether to trigger the pet light signal is determined based on the current distance, the relative motion trend, and the light signal trigger distance. When the pet light signal is triggered, the corresponding basic flashing frequency, basic light brightness, and light color are determined according to the pet type. The target flashing frequency is determined based on the relative motion trend and the base flashing frequency, and the target light brightness is determined based on the current ambient light intensity and the base light brightness. The target vehicle is controlled to emit a light warning signal based on the target flashing frequency, the target light brightness, and the light color.
[0008] Furthermore, in one embodiment of the present invention, the step of identifying the pet type of the target pet and the current distance and relative movement trend between the target pet and the target vehicle based on the environmental image information specifically includes: The environmental image information is input into a pre-trained pet detection model to obtain the species category of the target pet and its corresponding bounding box.

[0010] Furthermore, in one embodiment of the present invention, the step of determining whether to trigger a pet light signal based on the current distance, the relative movement trend, and the light signal trigger distance specifically includes: Determine whether the current distance is less than or equal to the light signal trigger distance, and determine whether the relative motion trend is a trend of approaching. When the current distance is less than or equal to the light signal trigger distance, and the relative movement trend is a moving closer trend, the pet light signal is triggered.
[0011] Furthermore, in one embodiment of the present invention, determining the target flashing frequency based on the relative motion trend and the base flashing frequency, and determining the target light brightness based on the current ambient light intensity and the base light brightness, specifically includes: The approach speed between the target pet and the target vehicle is determined based on the relative motion trend; The corresponding frequency adjustment coefficient is determined based on the approach speed, and the target flashing frequency is determined based on the base flashing frequency and the frequency adjustment coefficient. The corresponding light brightness ratio is determined based on the current ambient light intensity, and the target light brightness is determined based on the base light brightness and the light brightness ratio.
[0012] Furthermore, in one embodiment of the present invention, controlling the target vehicle to emit a light warning signal based on the target flashing frequency, the target light brightness, and the light color specifically includes: The corresponding RGB color ratio is determined based on the light color, and the RGB brightness ratio is determined based on the target light brightness and the RGB color ratio. A target PWM control signal is generated based on the RGB brightness ratio and the target flashing frequency, and the pet lights of the target vehicle are controlled to emit light warning signals based on the target PWM control signal.
[0013] Furthermore, in one embodiment of the present invention, after controlling the target vehicle to issue a light warning based on the target flashing frequency, the target light brightness, and the light color, the method further includes: Identify the target pet's reaction behavior based on the continuously acquired environmental image information; When the reaction behavior is active avoidance, the flashing frequency and brightness of the light warning are reduced until the distance between the target pet and the target vehicle is greater than the light warning trigger distance, and then the light warning is stopped. When the reaction behavior is to remain stationary, increase the flashing frequency and brightness of the warning lights; When the reaction behavior is a stress approach, the light and signal warnings stop, and the target vehicle is controlled to emit an audible warning.
[0014] On the other hand, embodiments of the present invention provide a vehicle light signal control device for pets, comprising: The data acquisition module is used to acquire the target vehicle's current vehicle operating condition, current ambient light intensity, and environmental image information; The pet recognition module is used to identify the pet type of the target pet and the current distance and relative movement trend between the target pet and the target vehicle based on the environmental image information. The light signal triggering judgment module is used to determine the light signal triggering distance based on the current vehicle operating conditions and the pet type, and to determine whether to trigger the pet light signal based on the current distance, the relative movement trend, and the light signal triggering distance. The basic parameter determination module is used to determine the corresponding basic flashing frequency, basic light brightness, and light color based on the pet type when the pet light signal is triggered. The light signal parameter adjustment module is used to determine the target flashing frequency based on the relative motion trend and the basic flashing frequency, and to determine the target light brightness based on the current ambient light intensity and the basic light brightness. The light signal warning control module is used to control the target vehicle to emit light signal warnings based on the target flashing frequency, the target light brightness, and the light color.

[0017] On the other hand, embodiments of the present invention also provide a computer program product, including a computer program that, when executed by a processor, implements the above-described pet-oriented vehicle light signal control method.
[0018] The advantages and beneficial effects of the present invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention: This invention acquires the current vehicle operating condition, current ambient light intensity, and environmental image information of the target vehicle.

[0026] Reference Figure 1 This invention provides a method for controlling vehicle lights for pets, specifically including the following steps: S101. Obtain the target vehicle's current operating condition, current ambient light intensity, and environmental image information; S102. Based on environmental image information, identify the pet type of the target pet and the current distance and relative motion trend between the target pet and the target vehicle; S103. Determine the light signal trigger distance based on the current vehicle operating condition and pet type, and determine whether to trigger the pet light signal based on the current distance, relative movement trend, and light signal trigger distance. S104. When the pet light signal is triggered, determine the corresponding basic flashing frequency, basic light brightness, and light color according to the pet type. S105. Determine the target flashing frequency based on the relative motion trend and the basic flashing frequency, and determine the target light brightness based on the current ambient light intensity and the basic light brightness. S106. Control the target vehicle to emit light warning signals based on the target flashing frequency, target light brightness, and light color.
[0027] This invention identifies the pet's pet type, distance from the vehicle, and relative movement trend. It then determines the trigger distance for the pet's light signal based on the vehicle's operating conditions, thereby determining whether to trigger the pet's light signal. The invention also adaptively adjusts the flashing frequency, brightness, and color of the pet's light signal to effectively alert the pet without startling it, thus improving vehicle safety.
[0028] This invention reads real-time vehicle operating data via the vehicle's CAN bus, including current vehicle speed, parking status (P gear / handbrake), turn signal status, and accelerator / brake pedal position; utilizes a light sensor above the vehicle's windshield to obtain real-time ambient light intensity values; covers driving / reversing scenarios with front and rear cameras, and focuses on the door opening safety area with left and right rearview mirror cameras, achieving 360° coverage of the vehicle body without blind spots. Simultaneously, the infrared supplementary lighting module automatically activates when the ambient brightness L < 30 lux, without affecting the pet's vision, while ensuring image recognition accuracy.
[0029] As a further optional implementation, the target pet's pet type, current distance, and relative movement trend between the target pet and the target vehicle are identified based on environmental image information, specifically including: S1021. Input the environmental image information into the pre-trained pet detection model to obtain the species category of the target pet and its corresponding bounding box; S1022. Determine the pet size of the target pet based on the size of the bounding box, and determine the pet type based on the species category and pet size; S1023. Determine the current distance between the target pet and the target vehicle based on the bounding box, and determine the relative motion trend between the target pet and the target vehicle based on the bounding boxes corresponding to the environmental image information of multiple consecutive frames.
[0030] Specifically, the acquired images undergo denoising, enhancement, and distortion correction. An AI image segmentation algorithm separates the foreground (pet) from the background (ground / obstacles). The pre-processed images are then input into a trained pet detection model to identify the pet's species (dog / cat / other) and categorize pets into small (≤30cm), medium (30-60cm), and large (>60cm) based on bounding box size, providing a basis for subsequent adjustment of signal parameters. For example, CBAM (Convolutional Block Attention Module) can be introduced on top of YOLOv12 to enhance the extraction of key features such as the pet's face and limbs through channel attention and spatial attention, thereby improving the accuracy of pet species identification. Finally, the pet type is determined based on the species and size, such as small cat or large dog.
[0031] By combining the parallax calculation of binocular cameras and millimeter-wave radar data, the real-time distance between the pet and the vehicle is accurately calculated. Then, by analyzing the changes in the pet's pixel position in five consecutive frames of images, the relative motion trend between the two is calculated. When the distance decreases at a speed greater than 0.5 m / s, it indicates a rapid approach trend; when 0 < the distance decreases at a speed ≤ 0.5 m / s, it indicates a slow approach trend; and when the distance remains constant or increases, it indicates a stationary or moving away trend.
[0032] As a further optional implementation, the light signal trigger distance is determined based on the current vehicle operating condition and pet type, specifically including: S1031. Determine the corresponding basic trigger distance based on the current vehicle operating conditions; S1032. Determine the corresponding pet correction coefficient based on the pet type; S1033. Determine the trigger distance of the light signal based on the base trigger distance and the pet correction coefficient.
[0033] Specifically, a base trigger distance is pre-set based on the vehicle's operating conditions. For example, the base trigger distances for different operating conditions such as parking and opening doors, reversing into a parking space, low-speed driving, and idling are 1.5m, 2m, 3m, and 2.5m, respectively. Simultaneously, a corresponding pet correction coefficient is pre-set based on different pet types, such as a pet correction coefficient of 1.6 for small cats and 1.2 for large dogs. The base trigger distance is determined based on the current vehicle operating conditions obtained from the previous steps, and the pet correction coefficient is determined based on the pet type obtained from the previous steps. Multiplying the two together yields the light signal trigger distance for the current scene.
[0034] As a further optional implementation, the decision to trigger the pet light signal is made based on the current distance, relative movement trend, and light signal trigger distance, specifically including: S1034. Determine whether the current distance is less than or equal to the light signal trigger distance, and determine whether the relative motion trend is a trend of approaching. S1035. When the current distance is less than or equal to the light signal trigger distance, and the relative movement trend is toward approaching, the pet light signal is triggered.
[0035] Specifically, this embodiment of the invention dynamically triggers pet light signals based on both distance and relative movement trend, avoiding false triggering. The pet light signal is triggered when the current distance is less than or equal to the signal triggering distance calculated in the preceding steps, and the relative movement trend is an approaching trend.
[0036] After determining that the pet light signal needs to be triggered, the corresponding basic flashing frequency, basic light brightness, and light color are determined according to the pet type. For example, when the pet type is a small cat, the corresponding basic flashing frequency is 2Hz, the basic light brightness is 1000nit, and the light color is warm yellow. When the pet type is a large dog, the corresponding basic flashing frequency is 1.5Hz, the basic light brightness is 1200nit, and the light color is amber.
[0037] As a further optional implementation, the target flashing frequency is determined based on the relative motion trend and the basic flashing frequency, and the target light brightness is determined based on the current ambient light intensity and the basic light brightness, specifically including: S1051. Determine the approach speed between the target pet and the target vehicle based on the relative motion trend; S1052. Determine the corresponding frequency adjustment coefficient based on the approach speed, and determine the target flashing frequency based on the basic flashing frequency and the frequency adjustment coefficient; S1053. Determine the corresponding light brightness ratio based on the current ambient light intensity, and determine the target light brightness based on the base light brightness and the light brightness ratio.
[0038] Specifically, in this embodiment of the invention, the basic flashing frequency and basic light brightness are adaptively adjusted according to the relative motion trend and the current ambient light intensity; the approach speed of the target pet and the target vehicle is determined according to the relative motion trend. If the pet approaches quickly, the basic frequency is increased by 50%; if it approaches slowly, the basic frequency is increased by 20%; and the basic frequency is maintained when the pet is stationary; the corresponding light brightness ratio is determined according to the current ambient light intensity. When the ambient light intensity is >5000 lux, the brightness is reduced by 20%; and when the light intensity is <100 lux, the brightness is increased by 10%.
[0039] As a further optional implementation, the target vehicle is controlled to emit a light warning signal based on the target flashing frequency, target headlight brightness, and headlight color, specifically including: S1061. Determine the corresponding RGB color ratio based on the light color, and determine the RGB brightness ratio based on the target light brightness and the RGB color ratio; S1062. Generate a target PWM control signal based on the RGB brightness ratio and the target flashing frequency, and control the pet lights of the target vehicle to emit light warnings based on the target PWM control signal.
[0040] Specifically, when the pet light signal is triggered, the vehicle ECU calls the corresponding RGB parameters based on the determined light color, and determines the brightness ratio of red, green, and blue based on the target light brightness (e.g., warm yellow corresponds to 100% red, 80% green, and 0% blue). Then, based on the RGB brightness ratio and the target flashing frequency, a target PWM control signal is generated. The ECU sends the PWM control signal to the light control module through the CAN bus to control the power supply duty cycle of the three LED beads (red, green, and blue) respectively, thereby adjusting the brightness ratio of each color and mixing to create the target color.
[0041] It should be noted that in this embodiment of the invention, a pet light is added to the vehicle to issue a pet light warning. If multiple pets of different sizes are detected at the same time, the ECU will select the color according to the principle of "large pets first", or alternately display the corresponding colors at 1-second intervals to ensure that all pets can be warned.
[0042] Pet lights can be installed at: below the front bumper or in the grille area, directly in front of the vehicle where the pet may be active; below the side mirrors on both sides of the vehicle, covering the blind spots on both sides of the vehicle; above the rear bumper, covering the area behind the vehicle.
[0043] As a further optional implementation, after controlling the target vehicle to issue a light warning based on the target flashing frequency, target light brightness, and light color, the method further includes: S201. Identify the target pet's reaction behavior based on continuously acquired environmental image information; S202. When the reaction behavior is active avoidance, reduce the flashing frequency and brightness of the light warning until the distance between the target pet and the target vehicle is greater than the light warning trigger distance, then stop the light warning. S203. When the reaction behavior is to remain stationary, increase the flashing frequency and brightness of the warning lights. S204. When the reaction behavior is a stressful approach, stop the light and signal warnings and control the target vehicle to emit an audible warning.
[0044] Specifically, based on continuously acquired environmental image information, the target pet's reaction behavior is identified and divided into three categories: active avoidance, i.e., the pet stops approaching and moves away from the vehicle, or runs away quickly; no obvious reaction, i.e. the pet continues to approach at the original speed, or stays in place and observes; and stress approach, i.e. the pet becomes excited due to light stimulation and instead speeds up to approach the vehicle.
[0045] When the pet's reaction is to actively avoid the vehicle, reduce the flashing frequency and brightness of the warning lights until the distance between the target pet and the target vehicle is greater than the trigger distance of the warning lights, then stop the warning lights. When the pet's reaction is to remain still, increase the flashing frequency and brightness of the warning lights, and add dynamic modes such as light gradients and breathing lights to attract the pet's attention. When the pet's reaction is to approach in response to stress, stop the warning lights and control the target vehicle to emit an audible warning, such as a low-volume, short-duration alert sound, in conjunction with the lights to guide the pet away.
[0046] The method steps of the embodiments of the present invention have been described above. It can be understood that the embodiments of the present invention identify the pet's pet type, distance from the vehicle, and relative movement trend, determine the trigger distance for the pet light signal based on the vehicle's operating conditions, thereby determining whether to trigger the pet light signal, and adaptively adjusting the flashing frequency, brightness, and color of the pet light signal. This avoids startling the pet while effectively reminding it, improving vehicle driving safety.
