Abstract
Description
Technical Field
[0001] This utility model relates to the field of vehicle body controller technology, and more specifically, to a vehicle body controller that adapts to external LED and halogen lamps. Background Technology
[0002] LED lights emit light through the characteristics of a PN junction, offering rapid start-up, high energy conversion efficiency, high brightness, and low energy consumption, while also being compact and space-saving. Halogen lamps, on the other hand, are an improvement on ordinary incandescent lamps. They are filled with halogen gas, allowing the filament to emit light continuously at high temperatures. They are characterized by low cost, strong penetrating power, and mature and stable technology. However, halogen lamps have relatively low brightness, a yellowish color temperature, shorter lifespan, and higher energy consumption. In contrast, LED lights offer a brighter, more energy-efficient, and more environmentally friendly lighting solution, gradually becoming the mainstream choice for modern automotive lighting.
[0003] However, halogen lamps still have certain advantages in rainy and foggy weather, as their yellow light has strong penetrating power and can provide better lighting effects.
[0004] In the field of automotive lighting, LEDs and halogen lamps are two common external light sources. However, due to the significant differences in the electrical characteristics of LEDs and halogen lamps, traditional vehicle control systems face numerous problems when controlling these two different types of lamps. Traditional vehicle control systems also suffer from poor compatibility with different types and specifications of lamps, making it difficult to detect and resolve potential lamp problems in a timely manner, which may lead to malfunctions.

[0024] like Figure 1-4 As shown in the embodiment of this utility model, a vehicle body controller that adaptively controls external LED and halogen lamps includes a high-drive chip circuit, an AD detection circuit, a left turn signal circuit, and a right turn signal circuit. The high-drive chip circuit is equipped with a high-drive chip 1 for driving the external lamps. The AD detection circuit, the left turn signal circuit, and the right turn signal circuit are respectively equipped with a left turn signal control I / O port 2, a right turn signal control I / O port 6, and an AD detection I / O port 3.

[0025] According to an embodiment of the present invention, a vehicle body controller that adapts to external LED and halogen lamps, in a specific embodiment, the left turn signal control I / O port 2 and the right turn signal control I / O port 6 output a high level.
[0026] According to an embodiment of the present invention, a vehicle body controller that adapts to external LED and halogen lamps is provided. In a specific embodiment, the B1+ power supply of the left turn signal circuit and the right turn signal circuit is 24V, and the resistance of resistors R79 and R81 is 1.5K.
[0027] According to an embodiment of the present invention, a vehicle body controller that adapts to external LED and halogen lamps is provided. In a specific embodiment, the left turn signal circuit and the right turn signal circuit are respectively provided with Q14, Q9, D15, R79 and Q16, Q11, D17, R81; a voltage of 23.3V is formed to the left of R79 and R81.
[0028] According to an embodiment of the present invention, a vehicle body controller that adapts to external LED and halogen lamps is provided. In a specific embodiment, the AD detection IO port 3 is connected to the output terminals of the left turn signal circuit and the right turn signal circuit, and detects the voltage at the output terminals.
[0029] According to an embodiment of the present invention, a vehicle body controller that adapts to external LED and halogen lamps is provided. In a specific embodiment, the controller determines whether the external lamp is a halogen lamp or an LED based on the voltage AD value detected by the AD detection IO port 3.
[0030] According to an embodiment of the present invention, a vehicle body controller that adapts to external LED and halogen lamps is provided. In a specific embodiment, the controller is a microcontroller, the high-drive chip 1 is a high-drive chip BTT6030, and D15 and D17 are anti-reverse diodes 4.
[0031] To facilitate understanding of the above-mentioned technical solutions of this utility model, the following detailed description of the above-mentioned technical solutions of this utility model is provided through specific usage methods.
[0032] In practical use, according to the vehicle body controller of this utility model that adaptively controls external LED and halogen lamps, the left turn signal control IO port 2 outputs a high level, transistors Q14 and Q9 are turned on, and the B1+ power supply (24V) forms a voltage of about 23.3V to the left of resistor R79 through Q9, D15, and R79. R79 (resistance: 1.5K) divides the voltage with the output of the external lamp. If the external lamp is a halogen lamp, since the resistance of a halogen lamp is only about ten to tens of ohms, the output voltage is very small, about 0 to 1V. Therefore, the voltage AD value of the AD detection IO port is very small. If the external lamp is an LED, since the LED has a large internal resistance, the output voltage is at least several volts, and the voltage AD value of the AD detection IO port is very large. Therefore, the controller determines whether the external lamp is a halogen lamp or an LED based on the voltage AD value detected by the AD detection IO port. If the external lamp is a halogen lamp, since the current through the halogen lamp is large, the controller can determine if a halogen lamp is missing. If the external lights are connected to LEDs, the controller will not detect a missing light because the current flowing through the LEDs is very small.
[0033] In summary, by utilizing the above-mentioned technical solution of this utility model and through the optimized and improved design of the product, a high-drive chip is used to drive external lamps, and the voltage at the output terminal of the high-drive chip is used to distinguish whether it is an LED or a halogen lamp. This enables the vehicle body controller to be more compatible with different types and specifications of lamps. Through real-time monitoring and adaptive adjustment, the vehicle body controller can promptly detect and resolve potential problems with the lamps, thus preventing malfunctions.
[0034] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
