Intelligent warning method, system and intelligent taillight device based on motor vehicle taillight

An intelligent warning system based on a motor vehicle taillight, applied to a motor vehicle integrated with an intelligent taillight device, comprising:

• a detection unit, configured to:
• monitor, in real-time, a current speed of a motor vehicle, a speed of a leading vehicle, and a speed of a following vehicle, and providing feedback to a preset main control module;
• and
• acquire, through the main control module, a real-time distance between the motor vehicle and the following vehicle to obtain a following vehicle distance, and a real-time distance between the motor vehicle and the leading vehicle to obtain and a leading vehicle distance;
• and
• a projection unit, configured to:
• control, through the main control module, a first projection module integrated in the motor vehicle taillight and a second projection module installed at a rear of the motor vehicle to project on a road surface in response to that a preset projection condition is met;
• control the first projection module to project on the road surface and projecting first information, comprising the current speed of the motor vehicle, the speed of the following vehicle, and the following vehicle distance, as projection content to provide a warning to the following vehicle in response to that the following vehicle distance is within a preset projection distance;
• control the second projection module to project on the road surface and projecting second information, comprising the current speed of the motor vehicle, the leading vehicle distance, and the speed of the leading vehicle, as projection content to provide a warning to the following vehicle and provide a driving status of the leading vehicle to the following vehicle in response to that the leading vehicle distance is less than a preset safety distance;
• and
• adjust projection ranges of the first projection module and the second projection module in real-time according to the following vehicle distance, so that there is always a distance between the projection range and the following vehicle, and the following vehicle is capable of observe the projection content.
