Description
Technical Field
[0001] The present application relates to the field of vehicle technology, and in particular to a method for prompting obstacles around a vehicle body based on surround ambient lighting. Background Art
[0002] With the rapid development of the automobile industry, cars have more and more functions, among which ambient lights are used more widely.
[0003] First of all, the ambient lighting in the car can significantly enhance the driving experience. By adjusting the color and brightness of the ambient lighting, a comfortable and pleasant in-car environment can be created for the driver and passengers, enhancing the sense of space and making driving and riding more comfortable. In addition, the ambient lighting provides a certain lighting effect when driving at night, helping the driver to see the display screen and indicator lights on the dashboard more clearly, thereby enhancing driving safety.
[0004] Secondly, ambient lighting helps to highlight individuality. Users can decorate according to their personal preferences to create a unique car interior space to meet personalized needs. The right light color and brightness can adjust the mood in the car. Ambient lighting provides soft, indirect light rather than direct strong light. This kind of light can reduce the glare effect, especially when driving at night, avoiding strong light directly irritating the eyes, reducing visual fatigue, improving the driver's night driving comfort, reducing the driver's fatigue, and bringing a relaxed and pleasant mood. For example, blue light can bring a sense of tranquility, while red light can add passion.
[0005] Finally, ambient lighting also has a significant effect in improving aesthetics and luxury. Well-designed ambient lighting can make the interior of the car look more refined and upscale, enhance the overall aesthetic, and make the car appear more luxurious and sporty. Through clever layout and light projection, ambient lighting can also enhance the sense of space in the car, making the interior space look more spacious and comfortable. In addition, in some cases, ambient lighting or body lighting outside the car (such as ground projection lights, taillights, etc.) can also improve the recognition of the vehicle at night or in low-visibility environments, making it easier for other drivers and pedestrians to see you, thereby avoiding potential collisions or misunderstandings.
[0006] However, the current purpose of ambient lighting is to enhance the atmosphere within the vehicle, resulting in low actual utilization of ambient lighting. Summary of the invention

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work belong to the scope of protection of the present application.
[0031] In the related art, the vehicle-mounted atmosphere light is installed inside the car and is a photographic device used to create a specific atmosphere. Different parts of the car (such as doors, roof, pedals, etc.) are often illuminated through LED light strips, point light sources, etc., and the visual effects and atmosphere in the car are increased through changes in color and brightness. Vehicle-mounted atmosphere lights are currently commonly used to enhance the atmosphere in the car, thereby enhancing the driver's and passengers' sense of experience. At present, some researchers also use atmosphere lights to prompt the driver's driving, thereby improving the driver's driving safety. Based on related technical research, it is found that the scope of use of atmosphere lights is still limited. Therefore, in this application, by controlling the atmosphere lights to prompt the relative position, relative speed and predicted driving direction of other vehicles, not only can the scope of use of the atmosphere lights be expanded, but also the driver's driving safety can be further improved.
[0032] In a first aspect, some embodiments of the present application provide a method for prompting obstacles around a vehicle body based on a surround ambient light, including: Determine the status information of obstacles around the vehicle body; Controlling the ambient light to indicate the status information; The status information includes at least one of real-time relative speed, relative position and driving direction.
[0033] When a vehicle is driving, the approach of obstacles may pose a threat to the driver's safety. Ambient lights, especially interior ambient lights, have been widely used in many cars in recent years. They can enhance the appearance of the vehicle and the driving experience of the owner. Based on this, in this embodiment, interior ambient lights are used to prompt the status information of obstacles, thereby improving the safety of the driver.
[0034] The real-time relative speed is the real-time speed of other obstacles relative to the vehicle.
[0035] The relative position is the position of other obstacles relative to the vehicle.
[0036] Since obstacles may affect the driver's safety when they are close to the vehicle, in this embodiment, the distance between the obstacle and the vehicle is divided into three intervals: First interval: set a first threshold value. When the relative distance between the vehicle and the obstacle is greater than the preset first threshold value, the color of the ambient light can be controlled to change or the ambient light can be controlled to be off. As an example, the ambient light can be turned red. Second interval: Set the second threshold. When the relative distance between the vehicle and the obstacle is less than or equal to the first threshold and greater than the second threshold, the color of the ambient light can be controlled to change again. For example, the ambient light can change to blue. The third interval: When the relative distance between the vehicle and the obstacle is less than the second threshold, the ambient light can be controlled to indicate the real-time relative speed, relative position and driving direction of the obstacle. As an example, the ambient light can be controlled in two colors, such as orange and green. One color can be used to indicate the relative position between the vehicle and the obstacle, and the other color can be used to indicate the real-time relative speed of the obstacle. The direction of the ambient light is used to improve the driving direction of the obstacle at the next moment, such as Figure 7 shown.
[0037] In the present application, the relevant personnel or the driver may set the first threshold and the second threshold according to the actual conditions of the driving environment and / or the driving habits of the driver. As an example, when the driver has the habit of driving at night, the driving environment is an environment with icy roads in winter, or the driver often drives the vehicle in an environment with complex road conditions, the first threshold and the second threshold may be set to larger values, and the second threshold may be set to 10 meters and the first threshold may be set to 20 meters.
[0038] In the present application, as an example, the relative distance between the vehicle and the obstacle can be obtained through the vehicle's own radar. When the relative distance is greater than the first threshold, the vehicle is in a relatively safe area and the ambient light is controlled to be off. When the relative distance is less than or equal to the first threshold and greater than the second threshold, it means that the obstacle is approaching the vehicle and is about to meet the vehicle. At this time, the driver needs to pay attention to safety and the color of the ambient light is controlled to change to blue. When the relative distance is less than or equal to the second threshold, the obstacle is about to reach the surroundings of the vehicle. Therefore, the ambient light can be controlled to start prompting the real-time relative speed, relative position and driving direction of the obstacle compared to the vehicle, thereby improving the driving safety of the driver of the vehicle.
[0039] In this application, the distance between the obstacle and the vehicle is indicated by the ambient light. In order to realize that the ambient light can clearly remind the driver, the relevant personnel and / or the driver do not reuse the selected colors when setting the color change of the ambient light, and the colors do not affect each other, so as to avoid unclear color prompts. In this application, in some special cases, when there is congestion on the traffic road, other vehicles are around the vehicle. At this time, the relative speed of other vehicles may be 0. At this time, the atmosphere cannot reflect the real-time relative speed of other vehicles. Then, the ambient light only has one color to remind other vehicles of their relative positions around the vehicle.
[0040] In the present application, when the relative distance is greater than the second threshold, there will be a situation where the color of the ambient light is controlled to change. When the relative distance is greater than the second threshold, and other vehicles pose a small threat to the safety of the vehicle, the ambient light only serves as a warning and does not reflect the relative position of the obstacle, the real-time relative speed, and the driving direction at the next moment. Therefore, relevant personnel or drivers can set it according to their actual situation and select the ambient light lighting area for warning. As an example, the outermost ambient light can be controlled to change color to prompt the driver.
[0041] In the present application, the relative distance between the vehicle and other vehicles can be obtained through any radar on the vehicle.
[0042] In some embodiments, the atmosphere light is formed by a plurality of lamp beads array; and controlling the atmosphere light to prompt the status information includes: The relative position is prompted based on the position of the target color lamp bead in the lamp bead array.
[0043] In the present application, when the distance between the obstacle and the vehicle is less than the second threshold, the lamp beads in the lamp bead array of the ambient light are controlled to change to the target color, so that the lamp beads of the target color in the ambient light are used to indicate the relative position between the obstacle and the vehicle.
[0044] In some embodiments, determining the state information of obstacles around the vehicle body includes: Determine a first coordinate system with the center of the vehicle body as the origin; Determine a first coordinate of the obstacle in the first coordinate system; The relative position is determined based on the first coordinates.
[0045] In this application, if Figure 2 As shown, a first coordinate system is established with the center of the vehicle at the current moment as the origin O, the longitudinal axis of the vehicle as the Y axis, and the lateral axis of the vehicle as the X axis, and the first coordinate of the obstacle at the current moment in the first coordinate system is obtained, that is, the coordinate of the obstacle at this moment.
[0046] The method for obtaining the first coordinate of the obstacle is based on at least three radars on the vehicle body, obtaining the distance R1, R2, R3...Rn between the obstacle and each radar at the moment, and making a circle with each radar as the center and R1, R2, R3...Rn as the radius. The intersection point A1 of all circles is used as the first coordinate of the obstacle in the first coordinate system at the current moment.
[0047] As an example, Figure 2 In this application, the first coordinate system is constructed by the vehicle. Figure 2 It can be found that the longitudinal axis of the vehicle used in the first coordinate system is the Y axis, and the transverse axis of the vehicle is the X axis. There are three radars on the vehicle (radar 1, radar 2, and radar 3). The distances between the vehicle and other vehicles are obtained through the three radars of the vehicle, which are distance R1, distance R2, and distance R3. Then, with each radar as the center of the circle and distance R1, distance R2, and distance R3 as the radius, three circles are obtained, as shown in Figure 3 As shown. Figure 3 In the figure, the coordinate of the vehicle is (0,0). The three circles have only one intersection point A1, which is the current coordinate of other vehicles, recorded as (X1,Y1). There are two radars at the rear of the vehicle, and the coordinates of the two radars are (-1,0) and (1,0) respectively. There is one radar on the side of the vehicle, and its coordinates are (1,1).
[0048] In some embodiments, the relative position is indicated based on the position of the target color lamp bead in the lamp bead array, including: Determine a second coordinate system with the center of the lamp bead array as the origin; Determine a first mapping relationship between the first coordinate system and the second coordinate system; Mapping the first coordinate to the second coordinate system based on the first mapping relationship, and determining a second coordinate of the obstacle in the second coordinate system; The lamp beads at the second coordinate are controlled to display the target color.
[0049] In the present application, a second coordinate system is established with the center of the lamp array as the origin, the first coordinate in the first coordinate system is mapped to the second coordinate system, the second coordinate of other vehicles in the second coordinate system at the current moment is determined, and the second coordinate is represented by lamp beads of the target color.
[0050] In this application, the areas where other vehicles may exist on the left and right sides of the vehicle are divided according to the relative positions of other vehicles around the vehicle, such as Figure 1As an example, the left side of the vehicle is divided into 9 areas, namely left 1, left 2, left 3, left 4, left 5, left 6, left 7, left 8, and left 9. Each area can be represented by a small matrix of lamp beads. The small matrix of each area is finally combined to form a lamp bead array on the left, which is used to represent the situation on the left side of the vehicle. Similarly, the right side of the vehicle is divided into 9 areas, namely right 1, right 2, right 3, right 4, right 5, right 6, right 7, right 8, and right 9. Similarly, a lamp bead array on the right is formed to represent the situation on the right side of the vehicle, as shown in FIG. Figure 6 As shown. The second coordinate system established is based on the center of the lamp bead array composed of the lamp bead array on the left and the lamp bead array on the right as the origin, the width direction of the lamp bead array as the horizontal coordinate of the second coordinate system, and the length direction of the lamp bead array as the vertical coordinate of the second coordinate system. The first mapping relationship is expressed as: the origin, X-axis and Y-axis of the first coordinate system correspond to the origin, X-axis and Y-axis of the second coordinate system one by one.
[0051] In this application, relevant personnel can adjust the value represented by a lamp bead according to actual conditions. As an example, in the lamp bead matrix, 5 lamp beads in the X-axis direction and 4 lamp beads in the Y-axis direction constitute a 5×4 left 6-area lamp bead small matrix, such as Figure 8 The area in the green box. In this application, the value represented by a lamp bead in the lamp bead matrix can be adjusted by relevant personnel according to actual conditions. As an example, in the width direction of the lamp bead matrix, the interval between adjacent lamp beads is set to 2, and in the length direction of the lamp bead matrix, the interval between adjacent lamp beads is set to 1; when the first coordinate of other vehicles in the first coordinate system is (-2,1), the system will convert the first coordinate in the first coordinate system into the second coordinate in the second coordinate system, and the lamp bead at position 1 will become the target color. When the first coordinate of other vehicles in the first coordinate system is (-3,1), the lamp bead at position 2 will become the target color.
[0052] In this application, the obtained ambient light can be divided into two parts according to the vertical coordinate of the lamp bead matrix, and installed on the left and right sides of the vehicle respectively. Splitting the ambient light can avoid concentrating the ambient light on a certain part of the car, which can also enhance the sense of participation and experience of other people besides the driver.
[0053] In some embodiments, the atmosphere light is formed by a plurality of lamp beads array; and controlling the atmosphere light to prompt the status information includes: The real-time relative speed is prompted based on the target array length of the light-emitting lamp beads.
[0054] In this application, the length of the light-emitting lamp beads in the atmosphere light is used to indicate the real-time relative speed of the obstacle.
[0055] In some embodiments, determining the state information of obstacles around the vehicle body includes: Determine a third coordinate system with the center of the vehicle body as the origin; Determine a third coordinate and a fourth coordinate of the obstacle in the third coordinate system; wherein the third coordinate corresponds to the first moment, and the fourth coordinate corresponds to the second moment; The real-time relative speed is determined based on the third coordinate, the fourth coordinate, the first time, and the second time.
[0056] As an example, a method for obtaining the real-time relative speed of an obstacle: obtaining the relative speed of other vehicles, and calculating the relative distance between the third coordinate and the fourth coordinate of other vehicles in the third coordinate system as follows: ; The real-time relative speed can be obtained by dividing the relative distance by time.
[0057] In some embodiments, the prompting of the real-time relative speed based on the target array length of the light-emitting lamp beads includes: Determine a second mapping relationship between the relative speed and the array length of the light-emitting lamp beads; Determine the target array length based on the second mapping relationship and the real-time relative speed; The lamp beads corresponding to the target array length are controlled to emit light.
[0058] As an example, in this application, the target array length of the light-emitting lamp beads represents the size of the real-time relative speed of other vehicles. Relevant technicians can set the size of the relative speed that the unit length of the array length of the light-emitting lamp beads can represent according to actual conditions. As an example, if Figure 5 As shown in the figure, when the relative speed value represented by the unit length is set to 3m / s, the target array length can be obtained according to the real-time relative speed of other vehicles and the unit length representative (relative speed value 3m / s). Relevant personnel should understand that a lamp bead cannot light up only part of it, so when the calculated length falls within the range of the lamp bead, the lamp bead will light up.
[0059] In some embodiments, the atmosphere light is formed by a plurality of lamp beads array; and controlling the atmosphere light to prompt the status information includes: The direction of the target array formed based on the luminous lamp beads indicates the driving direction.
[0060] In this application, the target array direction formed by the light-emitting lamp beads is used to indicate the direction of the obstacle at the next moment. As an example, in order to better indicate the relative position of other vehicles at the moment and the direction of travel at the next moment, the ambient light can connect the lamp beads with the target color used to indicate the equivalent position of other vehicles with the light-emitting lamp beads in the target array direction. The lamp beads with the target color serve as the current position of other vehicles, and the extension direction of the target array is the direction of travel of other vehicles at the next moment, such as Figure 5 shown.
[0061] In some embodiments, determining the state information of obstacles around the vehicle body includes: Determine a fourth coordinate system with the center of the vehicle body as the origin; Determine a fifth coordinate and a sixth coordinate of the obstacle in the fourth coordinate system; wherein the fifth coordinate corresponds to a third moment, the sixth coordinate corresponds to a fourth moment, and the fourth moment lags behind the third moment; The driving direction is determined based on the fifth coordinate and the sixth coordinate; wherein a first direction corresponding to the driving direction is a direction from the fifth coordinate to the sixth coordinate.
[0062] As an example, the method for obtaining the driving direction can be: based on at least three radars on the body of the vehicle, obtain the distance R1', R2', R3'...Rn' between other vehicles and each radar at the last moment, use each radar as the center of the circle, and use R1', R2', R3'...Rn' as the radius to make a circle, and use the intersection point A0 of all circles as the coordinate of the other vehicle at the last moment in the first coordinate system (i.e., the fifth coordinate); based on this method, obtain the coordinate of the other vehicle at this moment in the first coordinate system (i.e., the sixth coordinate), and use the direction of the line from the coordinate A0 of the other vehicle at the last moment to the coordinate A1 of the current moment as the turning direction of the other vehicle at the next moment, i.e., the direction vector In the direction of Figure 4 As shown in the figure, the distances between other vehicles and the vehicle at the last moment are obtained through the three radars of the vehicle, which are distance R1', distance R2', and distance R3', respectively. Then, three circles are obtained with the radar as the center and distance R1', distance R2', and distance R3' as the radius. The coordinates of the vehicle are (0,0), and the intersection point A0 of the three circles is the coordinates of other vehicles at the last moment, recorded as (X0, Y0), and A1 is the current coordinates of other vehicles, recorded as (X1, Y1). Connecting the coordinates (X0, Y0) and (X1, Y1) is the driving direction of other vehicles at the next moment.
[0063] In some embodiments, the target array direction formed by the light-emitting lamp beads indicates the driving direction, including: Determine the fifth coordinate system with the center of the lamp bead array as the origin; Determining a first angle between the first direction and a coordinate axis of the fourth coordinate system; Control the lamp beads corresponding to the target array direction to emit light; wherein the angle between the target array direction and the coordinate axis of the fifth coordinate system is a second angle, and the second angle is the same as the first angle.
[0064] As an example, the angle θ between the line connecting the coordinates of other vehicles at the previous moment and the current moment and the Y axis in the fourth coordinate system is obtained, and the value of the angle θ is mapped in the fifth coordinate system. In the fifth coordinate system, the target array direction and the Y axis in the fifth coordinate system form an angle θ', and the angle θ=angle θ', such as Figure 4-Figure 5 shown.
