The invention provides an automobile dynamic steering lamp circuit and an automobile dynamic steering lamp system, and the automobile dynamic steering lamp circuit comprises at least one driving control module which is configured to receive a power signal sent by an automobile body control module to start working, the driving control module outputs a first control signal at different time delays through the time delay unit; according to the automobile dynamic steering lamp circuit and the automobile dynamic steering lamp system, an external resistor is adopted to preset a high-precision time delay circuit to achieve the function of a dynamic running water steering lamp, the external resistor is configured, and the dynamic running water steering lamp can be switched on through the LED lamp set, so that the reliability of the automobile dynamic steering lamp system is improved, and the service life of the automobile dynamic steering lamp system is prolonged. The on-delay and the off-delay of the internal driving chip can be configured, so that the on-time and the off-time of the channel can be flexibly adjusted, and the cost of MCU hardware and the cost of software development, production and maintenance are saved.
Description
technical field [0001] The present application relates to the technical field of automobile signal lamps, and more particularly, to an automobile dynamic turn signal circuit. Background technique [0002] As an important signal indicating device in the headlight, the turn signal has an important function of prompting the attention of the surrounding vehicles and pedestrians when the vehicle is turning. According to regulations, all light-emitting diode (LED) light strings of turn signals only need to be lit within 200ms. Therefore, more and more car turn signals on the market have the function of dynamic water flow, and LED steering with dynamic effects The lights can better remind vehicles and pedestrians in the surrounding environment, and have a more eye-catching effect in rainy and foggy weather. [0003] The mainstream way to realize the dynamic turn signal in the market is to generate a specific delay by the Microcontroller Unit (MCU) to drive the dynamic lighting fun...
