Description

Technical Field

[0001] This invention belongs to the field of vehicle taillight technology, specifically relating to an intelligent vehicle taillight system and its control method, and a vehicle. Background Technology

[0002] Current vehicle taillights primarily convey single vehicle status information through fixed light patterns (such as red brake lights and yellow turn signals), which has the following technical limitations: 1. Limited information transmission dimensions: It can only express basic intentions such as braking and steering, and cannot transmit vehicle dynamic parameters (such as braking force and autonomous driving mode), which can easily lead to misjudgment by following vehicles (such as delayed reaction of following vehicles during emergency braking).

[0003] 2. Insufficient environmental adaptability: In low visibility environments such as rainy or foggy days, traditional light sources have weak penetration and fixed brightness, making them easily obscured by strong light (such as high beams), thus reducing the warning effect.

[0004] 3. Limited interaction scenarios: It can only perform simple visual interactions with vehicles behind it and cannot convey targeted information to pedestrians or non-motorized vehicles.

[0005] 4. Poor functional scalability: Due to fixed hardware, traditional taillights cannot add new functions (such as dedicated signals for autonomous driving scenarios) through software upgrades. This makes it difficult to meet the future development needs of intelligent and diversified vehicles, limiting the potential of taillights in improving traffic safety and intelligence.

[0006] Therefore, it is necessary to develop a new intelligent vehicle taillight system and its control method, as well as the vehicle itself. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent vehicle taillight system and its control method, as well as the vehicle itself, to improve driving safety.

[0008] To achieve the above objectives, the technical solution adopted by the present invention is as follows: In a first aspect, the intelligent vehicle taillight system of the present invention includes: The data acquisition module is used to acquire vehicle dynamic operating parameters and external environment information. The vehicle dynamic operating parameters include at least one of brake pedal travel, steering angle, vehicle speed and autonomous driving status data. The external environment information includes at least one of following vehicle distance and pedestrian position. The intelligent control module is connected to the data acquisition module and generates the vehicle's current operating condition information based on the vehicle's dynamic operating parameters and the external environment information. The taillights are connected to the intelligent control module and perform corresponding display and projection operations based on the current operating condition information.

[0009] Optionally, the taillight includes a taillight module, a taillight controller, a projection module, and an ultrasonic module. The taillight controller is connected to the taillight module, projection module, and ultrasonic module respectively, and controls the taillight module, projection module, and ultrasonic module to work according to the current operating condition information. This enriches the taillight's functionality. In addition to the traditional display function, a projection function is added, which can convey targeted information to pedestrians, non-motorized vehicles, etc. For example, when the vehicle is traveling at high speed and the driver triggers emergency braking, the red light strip is gradually illuminated from the outside to the inside of the LED matrix to simulate the braking distance. The entire screen is illuminated within 0.5 seconds, and at the same time, a laser projection projects a "△" warning graphic on the ground, triggering the ultrasonic module to emit a warning sound.

[0010] Optionally, the taillight controller includes a control unit, a power supply unit, and a supercapacitor, wherein the power supply unit is connected to the vehicle power supply, the supercapacitor, and the taillight, respectively. The power supply unit compares the charge of the supercapacitor with a preset lower threshold and a preset upper threshold. When the charge of the supercapacitor is less than or equal to the preset lower threshold, the power supply unit controls the vehicle power supply to electrically connect with the taillights, supplying power to the taillights via the vehicle power supply. Conversely, when the charge of the supercapacitor is greater than or equal to the preset upper threshold, the power supply unit controls the supercapacitor to electrically connect with the taillights, supplying power to the taillights via the supercapacitor. This allows for flexible control of either the vehicle power supply or the supercapacitor to power the taillights. When the supercapacitor's charge is insufficient, the vehicle power supply is used to ensure the taillights function normally; when the supercapacitor's charge is sufficient, the supercapacitor is used to power the taillights, reducing reliance on the vehicle power supply and improving energy efficiency. Simultaneously, the supercapacitor also helps stabilize the voltage, ensuring the stability of the taillight power supply.

[0011] Optionally, the taillight module includes: Lenses are used to transmit light; The LED matrix displays corresponding information based on the current operating condition information; A PCB board for mounting the electronic components of the taillight controller; The rear cover, connected to the lens, forms a closed space, within which the LED matrix and the PCB board are mounted. The lens of the taillight module transmits light, the LED matrix displays corresponding information based on current operating conditions, and the PCB board houses electronic components. The rear cover and lens form a closed space to protect the internal components. This structural design is reasonable, with clear division of labor among components, ensuring the normal operation and stability of the taillight module.

[0012] Optionally, the lens includes: A transparent lens layer is used for light transmission; A quantum dot thin film layer is disposed inside the transparent lens layer. The quantum dot thin film layer is connected to the PCB board. The taillight controller adjusts the voltage of the quantum dot thin film layer to achieve spectral shift of taillight emission. A transparent photovoltaic thin film layer, disposed inside the quantum dot thin film layer and connected to the PCB board, absorbs sunlight and converts it into electrical energy, which is then stored in the supercapacitor of the taillight controller. The transparent lens layer ensures light transmission, allowing the taillight's light to escape normally while allowing sunlight to enter. The taillight controller adjusts the voltage of the quantum dot thin film layer to shift the taillight's spectral distribution. This allows the taillight to adjust its color and characteristics according to different operating conditions and external environments; for example, increasing brightness in rainy weather and emitting a specific wavelength of red light in foggy weather, enhancing the taillight's warning effect in various environments. The transparent photovoltaic thin film layer absorbs sunlight and converts it into electrical energy stored in the supercapacitor, realizing the utilization of solar energy, providing additional energy for the taillight, further improving energy efficiency, and extending the taillight's lifespan.

[0013] Optionally, when the intelligent control module identifies rainy weather based on external environmental information, the taillight controller adjusts the voltage of the quantum dot thin film layer to increase brightness. In low-visibility environments like rain, increasing taillight brightness enhances penetration, making it easier for following vehicles to see the taillights, reducing the risk of rear-end collisions and other accidents, and improving driving safety.

[0014] Optionally, when the intelligent control module identifies foggy weather based on external environmental information, the taillight controller adjusts the voltage of the quantum dot thin film layer, causing the quantum dots in the thin film layer to emit red light with a wavelength between 90nm and 0nm. Red light has good penetrability in foggy weather, enabling it to propagate more effectively through the fog, improving the warning effect of the taillights, allowing following vehicles and other road users to clearly see the vehicle's taillights in foggy conditions, and reducing the occurrence of traffic accidents.

[0015] Secondly, the control method for an intelligent vehicle taillight system according to the present invention employs the intelligent vehicle taillight system as described in the present invention, and the method includes the following steps: The data acquisition module acquires and forwards vehicle dynamic operating parameters and external environment information. The vehicle dynamic operating parameters include at least one of brake pedal travel, steering angle, vehicle speed, and autonomous driving status data. The external environment information includes at least one of following vehicle distance and pedestrian position. The intelligent control module generates the vehicle's current operating condition information based on the vehicle's dynamic operating parameters and the external environment information, and transmits it to the taillights. The taillight performs corresponding display and projection operations based on the current operating condition information.

[0016] Optionally, the taillight performs corresponding display and projection operations based on the current operating condition information, specifically: When the current operating condition information indicates that the vehicle is traveling at high speed and triggers emergency braking, the taillights will gradually illuminate red from the outside to the inside, while simultaneously projecting warning graphics or text onto the ground and emitting a warning sound. When the current operating condition information indicates that the vehicle has entered Level 3 autonomous driving, the taillights illuminate the blue lights on the outer side of the light group, and simultaneously project a prompt image or text onto the ground. When the current operating condition information indicates that the user is braking and decelerating, the taillights illuminate red. The flashing frequency indicates the braking intensity; the stronger the braking, the faster the flashing frequency. Simultaneously, a warning image or text is projected onto the ground. When the vehicle is traveling at high speed and triggers emergency braking, the taillights gradually illuminate red from the outside in, projecting a warning image or text onto the ground and emitting a warning sound. This combination of warning methods more strongly attracts the attention of following vehicles and other road users, reminding them that the vehicle is in an emergency braking state, giving following vehicles more reaction time, and effectively preventing rear-end collisions. When the vehicle enters Level 3 autonomous driving, the outer blue light of the taillight assembly illuminates, simultaneously projecting a warning image or text onto the ground. This clearly informs surrounding road users that the vehicle is in autonomous driving mode, allowing them to understand the vehicle's driving mode and make appropriate judgments and actions, improving traffic safety and smoothness. The flashing frequency of the taillights also indicates the strength of the braking.

[0017] Thirdly, the vehicle described in this invention employs the intelligent vehicle taillight system as described in this invention.

[0018] The present invention has the following unexpected technical effects: 1. This invention breaks through the limitation of traditional taillights that can only express basic intentions such as braking and steering. It can transmit multi-dimensional information such as vehicle dynamic parameters and autonomous driving mode, enabling following vehicles and other traffic participants to understand the vehicle status more accurately, reducing misjudgments caused by insufficient information. For example, following vehicles can react in time during sudden braking, thus improving driving safety.

[0019] 2. By adjusting the brightness and wavelength of the taillights, this invention enhances the penetration of the taillights in low-visibility environments such as rain and fog, avoiding the problem of fixed brightness and easy obscuring by strong light in traditional light sources. This effectively improves the warning effect, enabling the taillights to clearly convey information to surrounding road users under different environmental conditions.

[0020] 3. This invention enriches the interaction methods between the taillight and the surrounding environment. It is not limited to visual interaction with the vehicle behind, but can also transmit information to pedestrians and non-motorized vehicles through projection and ultrasound, realizing cross-scene interaction and improving the overall safety and smoothness of traffic.

[0021] 4. This invention overcomes the shortcomings of traditional taillights, which have fixed hardware and cannot add new functions through software upgrades. It can meet the future development needs of intelligent and diversified automobiles and give full play to the potential of taillights in improving traffic safety and intelligence.

[0023] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0024] In the embodiments of this application, the terms "exemplary" or "for example" are used to indicate that something is an example, illustration, or description. Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner to facilitate understanding.

[0025] In the embodiments of this application, at least one can also be described as one or more, and multiple can be two, three, four or more, and this application does not impose any restrictions.

[0026] like Figure 1 As shown in this embodiment, an intelligent vehicle taillight system includes a data acquisition module 1, an intelligent control module 2, and a taillight 3. The data acquisition module 1 and the taillight 3 are respectively connected to the intelligent control module 2. The data acquisition module 1 is used to acquire vehicle dynamic operating parameters and external environmental information. The vehicle dynamic operating parameters include at least one of brake pedal travel, steering angle, vehicle speed, and autonomous driving status data. The external environmental information includes at least one of following vehicle distance and pedestrian position. The intelligent control module 2 generates the vehicle's current operating condition information based on the vehicle dynamic operating parameters and external environmental information. The taillight 3 performs corresponding display and projection operations according to the current operating condition.

[0027] In one possible embodiment, the intelligent control module 2 uses a machine learning model to generate the vehicle's current operating condition information based on the vehicle's dynamic operating parameters and external environmental information.

[0028] like Figure 2 As shown, in one possible embodiment, the taillight 3 includes a taillight module 31, a taillight controller 32, a projection module 33, and an ultrasonic module 34. The taillight controller 32 is connected to the taillight module 31, the projection module 33, and the ultrasonic module 34, respectively. The taillight controller 32 controls the taillight module 31, the projection module 33, and the ultrasonic module 34 to work according to the current operating condition information. This design enriches the functions of the taillight 3. In addition to the traditional display function, a projection function is added, which can convey targeted information to pedestrians, non-motorized vehicles, etc. For example, when the vehicle is traveling at high speed and the driver triggers emergency braking, the red light strip of the LED matrix 312 gradually lights up from the outside to the inside to simulate the braking distance. The entire screen lights up within 0.5 seconds, and at the same time, a laser projection projects a warning graphic on the ground and triggers the ultrasonic module 34 to emit a warning sound.

[0029] like Figure 5As shown, in one possible embodiment, the taillight controller 32 includes a control unit 322, a power supply unit 321, and a supercapacitor 323. The power supply unit 321 is connected to the vehicle power supply 4, the supercapacitor 323, and the taillight 3. The power supply unit 321 compares the charge level of the supercapacitor 323 with a preset lower threshold and a preset upper threshold. When the charge level of the supercapacitor 323 is less than or equal to the preset lower threshold, the power supply unit 321 controls the vehicle power supply to electrically connect to the taillight 3, supplying power to the taillight 3. Conversely, when the charge level of the supercapacitor 323 is greater than or equal to the preset upper threshold, the power supply unit 321 controls the supercapacitor 323 to electrically connect to the taillight 3, supplying power to the taillight 3. By comparing the charge level of the supercapacitor 323 with the preset thresholds, the power supply unit 321 of the taillight controller 32 flexibly controls the vehicle power supply 4 or the supercapacitor 323 to supply power to the taillight 3. When the supercapacitor 323 is low in power, the vehicle power supply 4 is used to ensure the normal operation of the taillight 3; when the supercapacitor 323 is fully charged, the supercapacitor 323 is used to power the taillight 3, which can reduce the dependence on the vehicle power supply 4 and improve energy utilization efficiency. At the same time, the supercapacitor 323 can also stabilize the voltage and ensure the stability of the power supply to the taillight 3.

[0030] In one possible embodiment, the preset lower threshold and the preset upper threshold are obtained through calibration and stored in the memory of the taillight controller 32.

[0031] like Figure 3 As shown, in one possible embodiment, the taillight module 31 includes a lens 311, an LED matrix 312, a PCB board 313, and a rear cover 314. The lens 311 transmits light; the LED matrix 312 displays corresponding information based on current operating conditions; the PCB board 313 mounts the electronic components of the taillight controller 32; and the rear cover 314 connects with the lens 311 to form a closed space, within which the LED matrix 312 and PCB board 313 are mounted. The lens 311 of the taillight module 31 transmits light, the LED matrix 312 displays corresponding information based on current operating conditions, the PCB board 313 mounts electronic components, and the rear cover 314 and lens 311 form a closed space to protect the internal components. This structural design is reasonable, with clear division of labor among components, ensuring the normal operation and stability of the taillight module.

[0032] like Figure 4As shown, in one possible embodiment, lens 311 includes a transparent lens layer 3111, a quantum dot thin film layer 3112, and a transparent photovoltaic thin film layer 3113. The transparent lens layer 3111 transmits light. The quantum dot thin film layer 3112 is disposed inside the transparent lens layer 3111 and is connected to the PCB board 313. The taillight controller 32 adjusts the voltage of the quantum dot thin film layer 3112 to achieve a spectral shift in the taillight's emission. The transparent photovoltaic thin film layer 3113, disposed inside the quantum dot thin film layer 3112 and connected to the PCB board 313, absorbs sunlight and converts it into electrical energy, which is then stored in the supercapacitor 323 of the taillight controller 32. The transparent lens layer 3111 enables light transmission, ensuring that the taillight 3's light can be emitted normally and that sunlight can be received normally. The taillight controller 32 adjusts the voltage of the quantum dot thin film layer 3112 to achieve a spectral shift in the taillight 3's emission. This allows the taillight 3 to adjust its light emission color and characteristics according to different operating conditions and external environments. For example, it can increase brightness in rainy weather and emit red light of a specific wavelength in foggy weather, enhancing the warning effect of the taillight 3 in different environments. The transparent photovoltaic thin film layer 3113 absorbs sunlight and converts it into electrical energy, which is stored in the supercapacitor 323, realizing the utilization of solar energy and providing additional energy for the taillight 3, further improving energy efficiency and extending the service life of the taillight 3.

[0033] In one possible embodiment, the transparent lens layer 3111 is made of transparent PC material. The quantum dot film layer 3112 is injection molded together with the transparent lens layer 3111, and the quantum dot film layer 3112 is connected to the PCB board 313 of the taillight module 31 via a flexible flat cable.

[0034] In one possible embodiment, when the intelligent control module 2 identifies rainy weather based on external environmental information, the taillight controller 32 adjusts the voltage of the quantum dot thin film layer 3112 to increase brightness, for example, by 30%. In low-visibility environments like rain, increasing the brightness of the taillights enhances their penetrating power, making them easier for following vehicles to see, reducing the risk of rear-end collisions and other accidents, and improving driving safety.

[0035] In one possible embodiment, when the intelligent control module 2 identifies foggy weather based on external environmental information, the taillight controller 32 adjusts the voltage of the quantum dot thin film layer 3112, causing the quantum dots in the quantum dot thin film layer 3112 to emit red light with a wavelength between 590nm and 620nm. Red light has good penetrability in foggy weather, enabling it to propagate more effectively through the fog, improving the warning effect of the taillight 3, allowing following vehicles and other road users to clearly see the vehicle's taillight 3 in foggy weather, and reducing the occurrence of traffic accidents.

[0036] In one possible embodiment, the projection module 8 is installed below the taillight module 31 and cannot be obstructed; the projection module 33 is used to project images and text.

[0037] like Figure 6 As shown in the embodiments of this application, a control method for an intelligent vehicle taillight system employs the intelligent vehicle taillight system described in the embodiments of this application, and the method includes the following steps: The data acquisition module 1 acquires and forwards vehicle dynamic operating parameters and external environment information. The vehicle dynamic operating parameters include at least one of brake pedal travel, steering angle, vehicle speed and autonomous driving status data, and the external environment information includes at least one of following vehicle distance and pedestrian position.

[0038] The intelligent control module 2 generates the vehicle's current operating condition information based on the vehicle's dynamic operating parameters and external environmental information, and transmits it to the taillight 3.

[0039] Taillight 3 performs corresponding display and projection operations based on the current operating condition information.

[0040] In one possible embodiment, the taillight 3 performs corresponding display and projection operations based on the current operating condition information, specifically: When the current operating condition information indicates that the vehicle is traveling at high speed and triggers emergency braking, taillight 3 illuminates red gradually from the outside in, simultaneously projecting warning graphics or text onto the ground and emitting a warning sound. This more strongly attracts the attention of following vehicles and other road users, reminding them that the vehicle is in an emergency braking state, giving following vehicles more reaction time, and effectively preventing rear-end collisions.

[0041] When the current operating condition information indicates that the vehicle has entered Level 3 autonomous driving, the outer blue lights of the taillights illuminate at point 3, while simultaneously projecting a prompt image or text onto the ground. This clearly informs surrounding road users that the vehicle is in autonomous driving mode, allowing them to understand the vehicle's driving mode and make appropriate judgments and actions, thereby improving traffic safety and smoothness.

[0042] When the current operating condition information indicates that the user is braking and decelerating, taillight 3 illuminates red. The flashing frequency indicates the braking intensity; the stronger the braking intensity, the faster the flashing frequency. Simultaneously, a warning image or text is projected onto the ground. The flashing frequency of taillight 3 reflects the strength of the braking.

[0043] In this application embodiment, a vehicle employs an intelligent vehicle taillight system as described in this application embodiment.

[0044] When the vehicle is powered on, the data acquisition module 1 transmits information from various sensors to the intelligent control module 2. The intelligent control module 2 integrates the sensor information, calculates and analyzes it to determine the current operating condition, and then transmits this condition to the taillight controller 32 of the taillight 3. The taillight controller 32 processes the information according to the current operating condition. For example, when the vehicle is traveling at high speed and the driver triggers emergency braking, the taillight controller 32 activates the "emergency braking signal mode": the LED matrix 312 gradually illuminates red light from the outside to the inside (simulating braking distance, full-screen illumination within 0.5 seconds), while a laser projection projects a warning graphic onto the ground, and triggers the ultrasonic module 34 to emit a warning sound. If the environmental sensors detect heavy rain, the quantum dot thin film layer 3112 automatically switches to a high-transmittance spectrum, increasing brightness by 30%. When the vehicle enters Level 3 autonomous driving, the taillight controller 32 drives the LED matrix 312 to emit blue light at the edge of the light group to generate a blue breathing light strip effect, while simultaneously projecting the text "Autonomous Driving in Progress" onto the ground. This invention improves interaction efficiency through multi-dimensional information transmission.

[0045] The above description of specific embodiments will make it clear to those skilled in the art that, for the sake of convenience and brevity, only the division of the above functional modules is used as an example. In practical applications, the above functions can be assigned to different functional modules as needed, that is, the internal structure of the device can be divided into different functional modules to complete all or part of the functions described above.

[0046] The above embodiments are preferred embodiments of the present invention, but the embodiments of the present invention are not limited to the above embodiments. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present invention shall be considered equivalent substitutions and shall be included within the protection scope of the present invention.
