[0025] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0026] Please see Figure 1 , Figure 1 The schematic block diagram of the infrared monitoring-based vehicle light 40 warning system provided in this embodiment of the present invention can be applied to automobiles or other moving objects with vehicle lights 40, such as robots.

[0027] Please see Figure 1 The aforementioned infrared monitoring-based vehicle light 40 warning system includes: a control unit 10, an infrared ranging sensor 20, a sampling unit 30, and a vehicle light 40; the infrared ranging sensor 20 is connected to the sampling unit 30, and the sampling unit 30 is connected to the control unit 10; the control unit 10 is connected to the vehicle light 40.

[0028] In this embodiment, vehicle driving safety is improved through integrated intelligent components. The system mainly consists of four key parts: a control unit 10, an infrared ranging sensor 20, a sampling unit 30, and vehicle lights 40.

[0029] Infrared ranging sensors 20 are installed in the headlights and taillights and are responsible for monitoring the distance between the vehicle and other vehicles in front and behind in real time. When other vehicles enter the set distance range, the infrared ranging sensors 20 emit and receive reflected infrared signals to determine the position information of the target object.

[0030] The sampling unit 30 is connected to the infrared ranging sensor 20 and is used to process the electrical signals received by the sensor. It not only acts as a signal transmission bridge, but also performs necessary filtering on the original electrical signals to remove possible noise interference and ensure that the data transmitted to the control unit 10 is accurate.

[0031] The signal processed by sampling unit 30 is sent to control unit 10, where it is converted into information reflecting the actual distance. Control unit 10 analyzes this information according to a preset logic algorithm to determine whether the distance between the vehicles in front and behind is within a safe range. Once a potential safety hazard is detected, such as insufficient distance between vehicles, control unit 10 will immediately take action, outputting a corresponding control signal to the headlights 40 through its I / O port. The analysis process is existing technology and will not be described in detail here.

[0032] As the system's actuator, the headlights 40 respond to commands from the control unit 10. Upon receiving the command, the headlights 40 change their brightness or flashing pattern according to a preset mode to warn drivers ahead and behind, reminding them to maintain an appropriate safe distance. Simultaneously, the control unit 10 feeds back information about the distance to vehicles in front and behind to the vehicle's control system, which is then displayed on the in-vehicle screen, allowing the driver to intuitively understand the surrounding environment and make timely and correct reactions to ensure driving safety.

[0033] In summary, the infrared monitoring-based vehicle light 40 warning system provided by this utility model effectively transmits the signal from the infrared ranging sensor 20 to the control unit 10, thereby achieving accurate judgment of the distance between the vehicle and the vehicle in front and behind, and accordingly implementing vehicle light 40 control to remind the drivers of the vehicles in front and behind. At the same time, the large screen on the vehicle body further reminds the driver, greatly improving driving safety.

[0034] In one embodiment, please refer to Figure 1 The aforementioned infrared monitoring-based vehicle light warning system 40 also includes a CAN transceiver 50 and a display screen 60. The CAN transceiver 50 is connected to the control unit 10, and the display screen 60 is connected to the CAN transceiver 50.

[0035] In this embodiment, the CAN transceiver 50 is connected between the control unit 10 and the vehicle network. In this system, the control unit 10 not only processes data from the infrared ranging sensor 20 and controls the headlights 40 to perform corresponding warning actions, but it also converts the analyzed distance information into a standard format suitable for transmission over the vehicle network and sends it to the CAN transceiver 50 via the CAN protocol. The CAN transceiver 50 is a high-efficiency data transmission device specifically designed for the automotive environment, ensuring that distance signals are transmitted quickly and stably to other parts of the vehicle, such as the body control system.

[0036] The display screen 60 is connected to the CAN transceiver 50, serving as a crucial terminal for information display. When the CAN transceiver 50 receives a distance signal from the control unit 10, it immediately forwards this information to the display screen 60 installed inside the vehicle. The display screen 60 can be a large multimedia screen located in the cockpit or a small, dedicated display specifically designed to show driving-related information. Regardless of its form, its primary function is to present the real-time distance between vehicles in front and behind, enabling the driver to immediately understand the positional relationships of surrounding vehicles and take appropriate driving measures to avoid collisions.

[0037] Therefore, in this specific embodiment, by introducing a CAN transceiver 50 and a display screen 60, the infrared monitoring-based vehicle light warning system 40 can construct a complete closed-loop mechanism from perception and decision-making to feedback. This not only enhances the functionality and practicality of the system, but also ultimately achieves the goal of reducing the risk of traffic accidents, providing strong technical protection for driving safety.

[0038] In one embodiment, please refer to Figure 1 The aforementioned control unit 10 includes a control chip, the model of which is S32K314.

[0039] In one embodiment, please refer to Figure 1 The aforementioned vehicle lights 40 include headlights and taillights. These lights not only serve normal illumination functions but also act as warning signals under specific conditions to remind vehicles in front and behind to maintain a safe distance. When a potential hazard is detected, the control unit 10 triggers the corresponding lighting mode to enhance driving safety.

[0040] In one embodiment, please refer to Figure 2 The sampling unit 30 mentioned above includes a sampling resistor, one end of which is connected to the infrared ranging sensor 20, and the other end of which is connected to the control unit 10.

[0041] In one embodiment, please refer to Figure 2 The sampling unit 30 mentioned above includes two capacitors, one end of which is connected to the two ends of the sampling resistor, and the other end of which is grounded.

[0042] This sampling unit configuration can effectively filter out noise interference, ensure the accuracy of measurement data, and protect subsequent circuits from transient voltage surges.

[0043] In one embodiment, the number of infrared ranging sensors 20 described above is two.

[0044] In one embodiment, the two infrared ranging sensors 20 described above are respectively connected to the headlights and taillights. Two infrared ranging sensors 20 are used for environmental perception. These two sensors are installed at the headlight and taillight positions respectively to facilitate all-around monitoring of distance changes in front of and behind the vehicle. This layout enables the system to grasp the surrounding traffic conditions in real time, providing the driver with more accurate safety warning information.

[0045] In one embodiment, the CAN transceiver 50 described above is a TCAN1044. The TCAN1044 supports data transmission rates up to 5 Mbps, making it suitable for demanding automotive applications and ensuring that data exchange between the control unit 10 and other vehicle components is both fast and reliable.

[0046] The infrared-based vehicle light warning system 40 can acquire real-time distance information between itself and vehicles in front and behind using infrared ranging sensors 20 installed on the headlights and taillights. To ensure that this information can be effectively processed by the control unit 10, a sampling circuit is designed to optimize signal transmission quality, ensuring that the control unit 10 can accurately interpret the data from the infrared ranging sensors 20.

[0047] The infrared ranging sensor 20 is installed at the front and rear of the vehicle, mainly on the headlights and taillights, and is responsible for detecting the distance between itself and the vehicles in front and behind, and generating corresponding electrical signals.

[0048] The sampling circuit serves as an intermediate link. It receives the raw signal from the infrared ranging sensor 20, performs preprocessing steps such as filtering, and converts it into a format suitable for the MCU to read, thereby improving the signal quality and reliability.

[0049] The control unit 10 employs a high-performance automotive-grade microcontroller. Based on the received distance data and the vehicle's current speed information, it intelligently determines whether a warning mode needs to be activated and adjusts the operating status of the high beam headlights and taillight turn signals accordingly. Specifically:

[0050] When the vehicle speed is ≤10km / h and the distance to the vehicle in front or behind is <1m, the headlights will turn on / off in 2-second intervals to activate the horn mode; at the same time, the taillights will flash rapidly at a frequency of 2.5Hz for 2 seconds, and then pause for 2 seconds.

[0051] For vehicles traveling at speeds between 10 km / h and 80 km / h, if the distance to the vehicles in front and behind is less than 10 m, the same light warning strategy will be adopted.

[0052] If the vehicle speed is greater than 80 km / h and the distance to the vehicles in front and behind is less than 50 m, the time interval between the horn flashing mode and the taillight flashing is shortened to once every 1 second to remind other drivers to maintain a safe distance more frequently.

[0053] The CAN transceiver 50 uses the automotive-standard TCAN1044 model to establish a communication bridge between the MCU and other vehicle systems, ensuring efficient synchronization between all relevant components. Specifically, it converts the distance information analyzed by the MCU into message format and sends it to the vehicle control system, ultimately displaying it on the in-vehicle screen for the driver's reference.

[0054] This system, through precise distance monitoring and real-time light warnings, improves the efficiency of interaction among road users and reduces the risk of potential collisions. The system not only relies on fixed threshold settings but also dynamically adjusts its warning strategy based on the vehicle's actual speed, demonstrating a highly user-friendly design. Utilizing the CAN network, information flow between various subsystems within the vehicle is achieved, particularly by directly presenting critical safety alerts to the driver, further enhancing the safety and convenience of the driving experience.

[0055] The aforementioned infrared monitoring-based vehicle light 40 warning system continuously monitors the distance between the vehicle and objects in front and behind through the infrared ranging sensor 20, and transmits the distance information to the control unit 10 for processing through the sampling unit 30. The control unit 10 intelligently analyzes the distance status based on the received data, and when it detects that the distance is too close, it immediately adjusts the working state of the vehicle light 40 to attract the attention of the driver and other road users. The vehicle light 40 not only provides illumination but also serves as a safety warning tool to help reduce the occurrence of traffic accidents.

[0056] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
