[0028] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present application and should not be construed as limiting the present application.

[0029] The vehicle tail light control method, computer-readable storage medium, vehicle, and vehicle tail light control device proposed by the embodiments of the present application will be described below with reference to the drawings.

[0030] Figure 1 It is a flowchart of the vehicle tail light control method according to the embodiment of the present application.

[0031] As Figure 1As shown, the vehicle taillight control method according to the embodiments of the present application may include the following steps:

[0032] S1, Obtain the vehicle speed during the current driving of the vehicle.

[0033] S2, Determine the vehicle speed range where the vehicle is located based on the vehicle speed.

[0034] S3, Control the number of lit LED lights and the display brightness based on the vehicle speed range.

[0035] Specifically, in an embodiment of the present application, the taillights of the vehicle are composed of multiple LED lights, and the LED lights are configured to be independently controlled. That is to say, the LED lights are divided into multiple groups, each group contains a certain number of LED lights, and these groups can be continuous or spaced, depending on the design requirements and visual effects, and each LED light can be independently turned on or off, or independently control the size of its brightness or independently control its blinking frequency, etc., and according to different vehicle speeds, the vehicle is allowed to light a specific number of lights as needed, so as to provide different lighting modes.

[0036] First, the vehicle speed during the current driving of the vehicle can be obtained. For example, a vehicle speed sensor such as a Hall effect sensor or a photoelectric sensor can be equipped on the vehicle to monitor the rotation speed of the wheel in real time. The vehicle speed sensor converts the detected wheel rotation speed into vehicle speed data and transmits it to the intelligent control system through the vehicle's controller area network bus or other communication protocols. The intelligent control system receives the vehicle speed data and processes it to determine the current speed of the vehicle.

[0037] After determining the vehicle speed, the vehicle speed range where the vehicle is located can be determined according to the vehicle speed. For example, the vehicle speed is divided into different ranges, such as a high-speed range, a medium-speed range, a low-speed range, and a stationary range. For example, the following vehicle speed ranges are determined in advance: high-speed range: above 100 km / h, medium-speed range: 60 km / h to 100 km / h, low-speed range: 0 km / h to 60 km / h, stationary range: 0 km / h. That is to say, the vehicle speed and the vehicle speed range where the vehicle is located are in a corresponding relationship. For example, when the vehicle speed is 120 km / h, the corresponding vehicle speed range can be determined as the high-speed range. Another example is that when the vehicle speed is 80 km / h, the corresponding vehicle speed range can be determined as the medium-speed range. Another example is that when the determined vehicle speed is 40 km / h, the corresponding vehicle speed range can be determined as the low-speed range. Another example is that when the determined vehicle speed is 0 km / h, the corresponding vehicle speed range can be determined as the stationary range.

[0038] After determining the vehicle speed range, the number of lit LED lights can be controlled according to the vehicle speed range. For example, when the vehicle speed is in the high-speed range, the number of lit LED lights can be controlled to be 0 to indicate that the current vehicle is driving at high speed and to prompt the following vehicle to control the safe distance. Another example is that when the vehicle speed is in the medium-speed range or the low-speed range, the number of lit LED lights can be controlled to be multiple, such as lighting the LED lights at the center position and its vicinity, or lighting the LED lights at regular intervals, to indicate that the current vehicle is driving at low speed or decelerating, so as to prompt the following vehicle to decelerate or change lanes in advance. Another example is that when the vehicle speed is in the stationary range, all the LED lights can be controlled to be lit to indicate that the current vehicle may have a malfunction and cannot move, so as to give a prominent prompt to the following vehicle.

[0039] After determining the vehicle speed range, the display brightness of the LED lights can also be adjusted according to the vehicle speed range. For example, when the vehicle speed is in the high-speed range, the display brightness can be controlled to be relatively low to avoid dazzling the following vehicle. Another example is that when the vehicle speed is in the medium-speed range or the low-speed range, the display brightness can be controlled to be moderate to ensure that the following vehicle can clearly see. Another example is that when the vehicle speed is in the stationary range, the display brightness can be controlled to be the highest to give a prominent prompt to the following vehicle.

[0040] Thus, the number of lit LED taillights and the display brightness are dynamically adjusted according to the real-time vehicle speed of the vehicle, thereby improving driving safety and driving experience. This design can not only adapt to different driving environments and vehicle speed changes, but also provide clear warning signals to the following vehicles in case of emergencies.

[0041] According to an embodiment of the present application, the LED lights are symmetrically grouped and designed from the center position at the rear of the vehicle to both sides.

[0042] Specifically, for example, the LED lights are divided into multiple groups, each group contains a certain number of LED lights, and these groups can be continuous or spaced, depending on the design requirements and visual effects. For the sake of aesthetics and functional consistency, the LED lights can be symmetrically arranged with the center line of the vehicle as the axis of symmetry, that is, the LED lights are symmetrically grouped and designed from the center position at the rear of the vehicle to both sides.

[0043] For example, the LED lights can be divided into 10 groups. For example, the first group is at the center position at the rear, including 1 LED light on each side of the center position. The second group is adjacent to the left and right sides of the center position at the rear, and the second group can include 2 LED lights, and so on. The LED lights can be symmetrically grouped and designed to both sides. Thus, it can provide a sense of balance visually, and can dynamically adjust the lighting effect according to the vehicle speed functionally, improving driving safety and driving experience. This design conforms to the development trend of the current automotive taillight system and has broad application prospects and market value.

[0044] According to an embodiment of the present application, the vehicle taillight control method further includes: controlling the number of lighting groups and display brightness of LED lights based on the vehicle speed range.

[0045] Specifically, the vehicle taillights are composed of multiple LED lights, which are divided into multiple groups, each of which contains a certain number of LED lights. For example, they can be divided into 10 groups, each of which contains 2 LED lights, and are symmetrically distributed from the center to both sides. Therefore, after determining the speed range in which the vehicle speed is located, the number of LED light groups and the display brightness can also be controlled according to the speed range.

[0046] For example, the vehicle speed is divided into different intervals, such as a high-speed interval, a medium-speed interval, a low-speed interval and a stationary interval. For example, the following speed intervals are predetermined: high-speed interval: above 100km / h, medium-speed interval: 60km / h to 100km / h, low-speed interval: 0km / h to 60km / h, stationary interval: 0km / h. In other words, the vehicle speed corresponds to the speed interval in which the vehicle is located. For example, when the vehicle speed is 120km / h, the corresponding speed interval can be determined as a high-speed interval. For another example, when the vehicle speed is 80km / h, the corresponding speed interval can be determined as a medium-speed interval. For another example, when the determined vehicle speed is 40km / h, the corresponding speed interval can be determined as a low-speed interval. For another example, when the determined vehicle speed is 0km / h, the corresponding speed interval can be determined as a stationary interval.

[0047] When the vehicle speed range is a stationary range, all LED light groups (such as groups 1-10) can be lit and set to the highest brightness to warn the rear vehicle to pay attention to the possible lane change or parking of the vehicle in front. When the vehicle speed is in a low speed range, more LED light groups (such as groups 1-7) can be lit and set to a higher brightness to remind the rear vehicle to pay attention to the speed and possible lane change of the vehicle in front. When the vehicle speed is in a medium speed range, fewer LED light groups, such as groups 1-3, can be lit and set to a lower brightness to avoid glare to the rear driver while maintaining a certain warning effect. When the vehicle speed is in a high speed range, only the LED light group (group 1) in the center position may be lit or the LED light group may not be lit and set to the lowest brightness to reduce visual interference to the rear driver.

[0048] As a result, the lighting status and brightness of the taillights can be dynamically adjusted according to different driving conditions and safety requirements, thereby improving driving safety and driving experience. This design can not only adapt to different driving environments and speed changes, but also provide clear warning signals to vehicles behind in emergency situations.

[0049] According to an embodiment of the present application, the vehicle speed in different vehicle speed ranges is negatively correlated with the number of lit groups or the number of lit units, and when the number of lit groups or the number of lit units increases, it increases sequentially from the center position of the tail towards both sides.

[0050] Specifically, in the control of vehicle tail lights, the negative correlation between the designed vehicle speed and the number of lit groups or the number of lit units of the tail lights is to provide an appropriate warning effect under different driving conditions, while taking into account energy efficiency and friendliness to other road users. The vehicle speed in different vehicle speed ranges is negatively correlated with the number of lit groups or the number of lit units, which means that as the vehicle speed decreases, the number of lit LED groups or units increases. On the contrary, as the vehicle speed increases, the number of lit LED groups or units decreases. This design provides a more obvious warning at low speed or when stationary, while reducing interference to the driver behind during high-speed driving.

[0051] Moreover, when it is necessary to increase the number of lit LED groups or units, starting from the center position of the vehicle tail, the number of lit groups or units increases symmetrically towards both sides in sequence. This design not only maintains symmetry visually but also provides a more uniform warning effect. Thus, by designing the negative correlation between the vehicle speed and the number of lit groups or the number of lit units, and increasing the number of lit groups or the number of lit units sequentially from the center position of the tail towards both sides, this intelligent vehicle tail light control system can provide an appropriate warning effect under different driving conditions, while taking into account energy efficiency and friendliness to other road users. This design improves driving safety and also provides a better user experience.

[0052] According to an embodiment of the present application, the vehicle tail light control method further includes: when a brake signal is obtained and the change amount of the vehicle speed within a preset time is greater than a preset change amount threshold, if the vehicle speed after braking decreases from a first preset vehicle speed range to a second preset vehicle speed range, then control the display brightness of the LED lights to increase. Wherein, the preset change amount threshold can be determined according to the actual situation.

[0053] Specifically, it is detected whether there is a braking signal currently. When a braking signal is obtained, the change amount of the vehicle speed within a preset time is judged against a preset change amount threshold to determine whether the current driver is performing an emergency braking operation. When a braking signal is obtained and the change amount of the vehicle speed within the preset time is greater than the preset change amount threshold, it indicates that the current driver may encounter a dangerous situation, or encounter an obstacle and is performing an emergency braking to quickly decelerate the vehicle. At this time, the interval in which the vehicle speed is located after braking is judged. When the vehicle speed decreases from the first preset vehicle speed interval (such as a relatively high vehicle speed interval, such as greater than 60 km / h) to the second preset vehicle speed interval (such as a medium vehicle speed interval, such as 10 - 60 km / h), the display brightness of the LED lamp can be controlled to increase, so as to improve the visibility of the vehicle taillights by increasing the brightness, thereby providing a stronger warning signal to the following vehicles and prompting them that the vehicle ahead is performing an emergency braking.

[0054] It should be noted that the braking system of the vehicle may include sensors for detecting whether the brake pedal is depressed and the depression force. When the brake pedal is depressed, the sensor will send a signal to the intelligent control system of the vehicle, indicating that the braking operation is in progress. The preset change amount threshold refers to the minimum value by which the vehicle speed needs to decrease within a preset time to trigger a specific taillight control strategy. The preset change amount threshold can be adjusted according to the vehicle specifications, road conditions, and safety requirements. In addition, the preset change amount threshold can also be dynamically adjusted according to real-time driving conditions (such as the wetness of the road surface, vehicle load, etc.).

[0055] Thus, the driving safety in the case of emergency braking can be significantly improved. The design of this system takes into account various factors in actual driving to ensure the most effective warning at critical moments.

[0056] According to an embodiment of the present application, the vehicle taillight control method further includes: if the vehicle speed after braking decreases from the first preset vehicle speed interval or the second preset vehicle speed interval to the third preset vehicle speed interval, then control the display brightness of the LED lamp to increase and control the LED lamp to blink at a preset frequency. Among them, the preset frequency can be determined according to the actual situation, and the vehicle speeds of the first preset vehicle speed interval, the second preset vehicle speed interval, and the third preset vehicle speed interval decrease in sequence.

[0057] Specifically, it is detected whether there is a braking signal currently. When a braking signal is obtained, the change amount of the vehicle speed within a preset time is judged against a preset change amount threshold to determine whether the current driver is performing an emergency braking operation. When a braking signal is obtained and the change amount of the vehicle speed within the preset time is greater than the preset change amount threshold, it indicates that the current driver may encounter a dangerous situation, or encounter an obstacle and is performing an emergency braking to quickly decelerate the vehicle. At this time, the interval in which the vehicle speed is located after braking is judged. When the vehicle speed decreases from the first preset vehicle speed interval (such as a relatively high vehicle speed interval, such as greater than 60 km / h) to the third preset vehicle speed interval (such as a relatively low vehicle speed interval, such as 0 - 10 km / h), or when the vehicle speed decreases from the second preset vehicle speed interval (such as a medium vehicle speed interval, such as 10 - 60 km / h) to the third preset vehicle speed interval (such as a relatively low vehicle speed interval, such as 0 - 10 km / h), the display brightness of the LED lamp is controlled to increase and the LED lamp is controlled to flash at a preset frequency, so as to improve the visibility of the vehicle taillight by increasing the brightness and flashing, and can more effectively remind the following vehicle to pay attention that the vehicle in front is decelerating, thereby reducing the risk of rear-end collision accidents.

[0058] It should be noted that the preset frequency can be preset according to the settings of the vehicle manufacturer or the requirements of traffic regulations to ensure that effective warnings can be provided in different situations.

[0059] Thus, more effective warnings can be provided during the vehicle deceleration process, thereby improving driving safety. The design of this system takes into account various factors in actual driving to ensure the most effective warning at critical moments.

[0060] In addition, in an embodiment of the present application, the display color of the LED lamp can also be controlled according to the vehicle speed interval in which the vehicle speed is located. For example, when the vehicle speed is relatively low, such as when the vehicle speed is reduced to the third preset vehicle speed interval during emergency braking, the display color of the LED lamp can be controlled to be dark red to send a clear warning signal to the following vehicle. When the vehicle speed is relatively high, such as when the vehicle is driving at a relatively high speed on a highway section, such as when the vehicle speed is in the first preset vehicle speed interval, the display color of the LED lamp can be controlled to be light red, and the following vehicle can control the safe distance.

[0061] In summary, the LED lamp is divided into 10 groups, and Table 1 is taken as a specific example for detailed description. Table 1 is as follows:

[0062]

[0063]

[0064] As can be seen from Table 1, after obtaining the vehicle speed X, the size of X is judged, and the vehicle speed range where the vehicle speed is located can be determined according to X. For example, when X is greater than or equal to 100 km / h, such as X being 120 km / h, it can be determined that the vehicle speed is in the preset range 1, and at this time, the tail lamp can be controlled not to light up; when X is greater than or equal to 90 km / h and less than 100 km / h, such as X being 95 km / h, it can be determined that the vehicle speed is in the preset range 2, and at this time, 1 group of LED lights can be controlled to light up; when X is greater than or equal to 80 km / h and less than 90 km / h, such as X being 85 km / h, it can be determined that the vehicle speed is in the preset range 3, and at this time, 2 groups of LED lights (1 group and 2 groups) can be controlled to light up; when X is greater than or equal to 70 km / h and less than 80 km / h, such as X being 75 km / h, it can be determined that the vehicle speed is in the preset range 4, and at this time, 3 groups of LED lights (1 group - 3 groups) can be controlled to light up; when X is greater than or equal to 60 km / h and less than 70 km / h, such as X being 65 km / h, it can be determined that the vehicle speed is in the preset range 5, and at this time, 4 groups of LED lights (1 group - 4 groups) can be controlled to light up; when X is greater than or equal to 50 km / h and less than 60 km / h, such as X being 55 km / h, it can be determined that the vehicle speed is in the preset range 6, and at this time, 5 groups of LED lights (1 group - 5 groups) can be controlled to light up; when X is greater than or equal to 40 km / h and less than 50 km / h, such as X being 45 km / h, it can be determined that the vehicle speed is in the preset range 7, and at this time, 6 groups of LED lights (1 group - 6 groups) can be controlled to light up; when X is greater than or equal to 30 km / h and less than 40 km / h, such as X being 35 km / h, it can be determined that the vehicle speed is in the preset range 8, and at this time, 7 groups of LED lights (1 group - 7 groups) can be controlled to light up; when X is greater than or equal to 20 km / h and less than 30 km / h, such as X being 25 km / h, it can be determined that the vehicle speed is in the preset range 7, and at this time, 8 groups of LED lights (1 group - 8 groups) can be controlled to light up; when X is greater than or equal to 10 km / h and less than 20 km / h, such as X being 15 km / h, it can be determined that the vehicle speed is in the preset range 8, and at this time, 9 groups of LED lights (1 group - 9 groups) can be controlled to light up; when X is greater than or equal to 0 km / h and less than 10 km / h, such as X being 5 km / h, it can be determined that the vehicle speed is in the preset range 10, and at this time, 10 groups of LED lights (1 group - 10 groups) can be controlled to light up.

[0065] And when the vehicle is in a situation of rapid deceleration, such as when reducing from a relatively high speed to between 10 km / h and 60 km / h, the LED lights can be controlled to be in a high - brightness state, that is, to be displayed with a relatively high brightness. And when the vehicle speed drops to 0 - 10 km / h, the LED lights can be controlled to be in a flashing state to send a clear warning signal to the following vehicles.

[0066] The following combines Figure 2 to describe the method of this application.

[0067] As a specific example, the vehicle taillight control method of the present application may include the following steps:

[0068] S101, obtain the vehicle speed during the current driving of the vehicle.

[0069] S102, determine the vehicle speed range where the vehicle is located based on the vehicle speed.

[0070] S103, control the number of lit LED lights and the display brightness based on the vehicle speed range.

[0071] S104, determine whether a brake signal is obtained and whether the change amount of the vehicle speed within a preset time is greater than a preset change amount threshold. If yes, execute step S105; if no, execute step S101.

[0072] S105, determine whether the vehicle speed after braking decreases from a first preset vehicle speed range to a second preset vehicle speed range. If yes, execute step S106; if no, execute step S107.

[0073] S106, control the display brightness of the LED lights to increase.

[0074] S107, determine whether the vehicle speed after braking decreases from the first preset vehicle speed range or the second preset vehicle speed range to a third preset vehicle speed range. If yes, execute step S108; if no, execute step S101.

[0075] S108, control the display brightness of the LED lights to increase and control the LED lights to flash at a preset frequency.

[0076] In summary, according to the vehicle taillight control method of the embodiments of the present application, the vehicle speed during the current driving of the vehicle is obtained, the vehicle speed range where the vehicle is located is determined based on the vehicle speed, and the number of lit LED lights and the display brightness are controlled based on the vehicle speed range. Thus, this method can meet the safety requirements in diverse driving environments, reduce the occurrence of traffic accidents, and improve the user experience of using the vehicle.

[0077] Corresponding to the above embodiments, the present application also proposes a computer-readable storage medium.

[0078] The computer-readable storage medium of the embodiments of the present application stores a program, and when the program is executed by a processor, it implements the above vehicle taillight control method.

[0080] Corresponding to the above embodiments, the present application also proposes a vehicle.

[0081] As Figure 3 shown, the vehicle 200 according to the embodiment of the present application may include: a memory 210, a processor 220, and a program stored on the memory 210 and executable on the processor 220. When the processor 220 executes the program, the above-mentioned vehicle taillight control method is implemented.

[0082] According to the vehicle of the embodiment of the present application, by executing the above-mentioned vehicle taillight control method, it can meet the safety requirements in diverse driving environments, reduce the occurrence of traffic accidents, and improve the user's driving experience.

[0083] Corresponding to the above embodiments, the present application also proposes a vehicle taillight control device.

[0084] As Figure 4 shown, the vehicle taillight control device 100 according to the embodiment of the present application includes: an acquisition module 110, a determination module 120, and a control module 130.

[0085] Among them, the acquisition module 110 is used to acquire the vehicle speed during the current driving process of the vehicle. The determination module 120 is used to determine the vehicle speed interval where the vehicle is located based on the vehicle speed. The control module 130 is used to control the number of lit LED lights and the display brightness based on the vehicle speed interval.

[0086] According to an embodiment of the present application, the LED lights are symmetrically grouped and designed from the center position at the rear of the vehicle to both sides.

[0087] According to an embodiment of the present application, the control module 130 is further used to: control the number of lit LED light groups and the display brightness based on the vehicle speed interval.
