[0071] In the present disclosure, unless otherwise specified, the terms "first", "second", etc. are used to describe various elements and are not intended to limit the positional relationship, timing relationship or importance relationship of these elements. Such terms are only used to distinguish one element from another. In some examples, the first element and the second element may refer to the same instance of the element, and in certain cases, based on the context description, they may also refer to different instances.

[0072] In the description of various examples in the present disclosure, the terms used are only for the purpose of describing specific examples and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element may be one or more. As used herein, the term "plurality" means two or more, and the term "based on" should be interpreted as "at least partially based on". In addition, the terms "and / or" and "at least one of..." cover any one of the listed items and all possible combinations.

[0073] During daily driving, especially at night or in a dim scene, it is generally required that the vehicle lights be turned on according to regulations. If the vehicle lights are wrongly turned off, the vehicle driving on the road will have a greater impact on its own and other vehicles' safety. In actual situations, when encountering a vehicle with its lights not properly turned on (i.e., the target vehicle), one can only drive to the left, right, front or rear of the target vehicle and the driver manually honks to give a reminder. However, this method generally cannot enable the driver of the target vehicle to timely and accurately know that the other party is reminding them that their vehicle lights are not on.

[0074] The embodiments of the present disclosure provide a vehicle information processing method so as to at least be able to effectively remind a vehicle whose vehicle lights are wrongly turned off.

[0075] The exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0076] Figure 1 The flowchart of a vehicle information processing method 100 according to an exemplary embodiment is shown. The vehicle implementing this vehicle information processing method includes at least a sound output device and a plurality of visual display devices distributed around the vehicle body.

[0077] Referring to Figure 1 , the vehicle information processing method 100 includes step 110 and step 120. In step 110, first, it is confirmed whether the target vehicle adjacent to the vehicle has not turned on the headlights correctly. If it is determined that the target vehicle has not turned on the headlights correctly, a reminder event is triggered. In step 120, in response to the reminder event being triggered, an auditory reminder is output using the vehicle's sound output device and a visual reminder is displayed using the vehicle's plurality of visual display devices. In order for the target vehicle to see the visual reminder, the visual display device corresponding to the target vehicle among the plurality of visual display devices distributed around the vehicle body is used to display the visual reminder. The method 100 triggers a reminder event based on the fact that the adjacent target vehicle has not turned on the headlights correctly, and by generating an auditory reminder and a visual reminder, enables the driver of the target vehicle to timely and accurately know that they have not turned on the headlights.

[0078] Regarding step 110, the present disclosure can trigger the reminder event in an automatic manner and a manual manner. Figure 2 The flowchart of a method 200 for determining that a reminder event is triggered according to an exemplary embodiment is shown. In Figure 2 this method, the reminder event is triggered in an automatic manner.

[0079] Referring to Figure 2 , the method 200 for determining that a reminder event is triggered includes the following steps. First, environmental light intensity data detected by at least one light sensor is obtained (step 210). Detecting the environmental light intensity data is to evaluate whether the vehicle needs to turn on the headlights in the current environment. If the environmental light intensity data detected by at least one light sensor indicates that the environmental brightness is lower than a predetermined threshold, it means that the headlights need to be turned on. If the target vehicle has not turned on the headlights, the target vehicle needs to be reminded to turn on the headlights. On the contrary, it means that the headlights do not need to be turned on in the current environment, and there is no need to remind the target vehicle to turn on the headlights. In some embodiments, the headlights need to be turned on when it is night or the light dimness is equivalent to night, otherwise the headlights do not need to be turned on.

[0080] After obtaining the environmental light intensity data, in response to the environmental light intensity data indicating that the environmental brightness is lower than a predetermined threshold, image data from at least one in-vehicle camera is obtained (step 220). Among them, the image data of at least one in-vehicle camera obtained in step 220 will be used to determine whether the target vehicle has turned on the headlights.

[0081] After obtaining the image data of at least one vehicle-mounted camera, preprocess the image data. In some embodiments, the preprocessing includes extracting image frames from the image data, i.e., frame extraction operation (step 230). For the image frames after frame extraction, crop the central region of the image (step 240). In some embodiments, first perform regional cropping of the central region to exclude other vehicles in other lanes and other interferences such as roadside lights, and only process the image region within a short distance in front of or behind the same lane. By cropping the image frames, the subsequent detection region will be compressed. For example, it is compressed to only contain 1 or 2 vehicles in front or behind, and exclude farther vehicles from entering the subsequent detection region. It should be understood that the central region cropping can be performed on the images obtained by each camera. Excluding other vehicles in other lanes, roadside lights, and the light ranges of farther vehicles in front and behind reduces the detection range and thus improves the detection accuracy. After cropping, enhance the brightness of the central region of the image (step 250). It can be understood that if the vehicles in the image region to be processed do not turn on their lights, the overall brightness of the image region will be relatively dark and the distribution range will be narrow, with low distinguishability. Therefore, introducing the image brightness enhancement step 250 will increase the overall brightness and distinguishability to optimize the quality of the subsequent detection algorithm.

[0082] After the preprocessing step, process the preprocessed image data to determine whether the target vehicle has its lights off (step 260). In some embodiments, step 260 includes using at least one neural network model to determine whether the target vehicle has its lights off from the preprocessed image data. The at least one neural network model includes: at least one target detection model for detecting the target vehicle from the preprocessed image data; at least one target segmentation model for segmenting the vehicle contour region containing the detected target vehicle from the preprocessed image data; and at least one target classification model for identifying whether the target vehicle has its lights off from the segmented vehicle contour region. In some embodiments, for the four directions of front, rear, left, and right, one target detection model, one target segmentation model, and one target classification model are respectively provided.

[0083] Based on the above three neural network models, method 200 further includes the following three steps 270-290. Step 270 is based on at least one object detection model. The at least one object detection model is trained to select the vehicle target closest to the vehicle as the target vehicle from multiple vehicle targets when multiple vehicle targets are detected from the preprocessed image data. Step 280 is based on at least one object segmentation model to segment out the vehicle contour area containing the detected target vehicle from the preprocessed image data. This step is to increase the accuracy of detecting whether the lights are on. By this step, instead of directly detecting the unlit vehicle target through a deep neural network on the original image according to the method of the present disclosure, the image is first semantically segmented by a pre-trained semantic segmentation deep neural network, and the image area part of the closest vehicle is extracted, thereby excluding the interference factors of other light source noises outside the vehicle contour. Step 290 is based on at least one object classification model to identify whether the target vehicle has its lights off from the segmented vehicle contour area.

[0084] In addition to Figure 2 triggering the reminder event in an automatic manner as shown, the present disclosure can also trigger the reminder event manually. Figure 3 The flowchart of the manual method 300 for determining that the reminder event is triggered according to an exemplary embodiment is shown.

[0085] Referring to Figure 3 , method 300 includes step 310 and step 320. In step 310, a user input of the vehicle is received. In some embodiments, the user input includes the user pressing a touch screen button or a physical button. The touch screen or the physical button is designed to be able to distinguish 4 directions, corresponding to the reminders in the front, rear, left, and right 4 directions respectively. The physical button is placed at a position convenient for the driver to use, such as on the steering wheel. It should be understood that the appearance design of the user input component can have diversity as long as it can distinguish at least 4 input areas to correspond to the front, rear, left, and right 4 directions respectively. In step 320, in response to receiving the user input, it is determined that the reminder event is triggered. In some embodiments, the user presses the button corresponding to the reminders in the front, rear, left, and right 4 directions. In response to the user's pressing, the reminder event in the corresponding direction is triggered.

[0086] Figure 4A schematic diagram further shows the positions of a plurality of visual display devices. In some embodiments, the plurality of visual display devices include a front visual display device 401, a rear visual display device 402, a left visual display device 403, and a right visual display device 404 that are respectively located around the vehicle body. In response to a target vehicle being in front of the vehicle, the front visual display device 401 is caused to display a visual reminder. In response to the target vehicle being behind the vehicle, the rear visual display device 402 is caused to display a visual reminder. In response to the target vehicle being on the left side of the vehicle, the left visual display device 403 is caused to display a visual reminder. In response to the target vehicle being on the right side of the vehicle, the right visual display device 404 is caused to display a visual reminder.

[0087] The specific positions of the front visual display device 401, the rear visual display device 402, the left visual display device 403, and the right visual display device 404 can be adjusted as needed, as long as they can be easily seen by the user of the target vehicle. In some embodiments, the front visual display device 401 can be located at the front grille part of the vehicle. The rear visual display device 402 can be located on the rear window. The left visual display device 403 and the right visual display device 404 can be respectively located on the outer sides of the driver's window and the co-driver's window, and on the outer sides of the left and right rearview mirrors. In another embodiment, the left visual display device 403 and the right visual display device 404 can be respectively located in the door areas below the driver's window and the co-driver's window glass.

[0088] It should be understood that each of the plurality of visual display devices can adopt any display device capable of displaying visual images. In some embodiments, the front visual display device 401 is an LED light array device. The rear visual display device 402, the left visual display device 403, and the right visual display device 404 can be transparent LED display films pasted on the inner or outer side of the window glass. When the left visual display device 403 and the right visual display device 404 are respectively located in the door areas below the driver's window and the co-driver's window glass, the left visual display device 403 and the right visual display device 404 can adopt a three-layer compression design. As Figure 5 shown, in the three-layer compression design, the bottom layer 501 is the normal vehicle body paint, the middle layer 502 is a transparent LED display film, and the top layer 503 is a hard transparent covering layer.

[0089] In some embodiments, displaying a visual reminder includes causing the visual display device corresponding to the target vehicle among the plurality of visual display devices to display text and / or patterns reminding that the vehicle lights are not turned on. The text reminding that the vehicle lights are not turned on is, for example, "Vehicle lights not turned on", "Please turn on vehicle lights", etc. The patterns reminding that the vehicle lights are not turned on include any pattern designs with a reminding meaning, for example, a pattern similar to the general vehicle light logo can be adopted. In some embodiments, displaying a visual reminder further includes causing the visual reminder to flash at a certain frequency.

[0090] Return to step 120. In addition to using multiple visual display devices of the vehicle to display visual reminders, an auditory reminder can also be output using the vehicle's sound output device. In some embodiments, the sound output device includes an on-vehicle horn. Outputting the auditory reminder includes sounding the on-vehicle horn. The horn is used to attract the attention of the driver of the target vehicle, and the visual reminder is used to display reminder content (such as words and / or patterns like "lights off", "please turn on the lights", etc.).

[0091] It should be understood that although the various operations are depicted in the drawings as occurring in a particular order, this should not be construed as requiring that the operations must be performed in the particular order shown or in a sequential order, nor should it be construed as requiring that all of the illustrated operations be performed to obtain the desired result.
