Title: INFORMATION PROMPT METHOD FOR PREVENTING VEHICLE REAR-END COLLISION ACCORDING TO VEHICLE SPEED, AND BRAKE LIGHT SYSTEM
Abstract:
The invention belongs to the technical field of electronics, and provides an information prompt method for preventing a vehicle rear-end collision according to vehicle speeds, and a brake light system. The method comprises: recording a vehicle speed interval of a vehicle behind a user and an inter-vehicle distance threshold matched with the vehicle speed interval; detecting the vehicle speed of the vehicle behind the user and whether the inter-vehicle distance between the user vehicle and the rear vehicle is less than the inter-vehicle distance threshold matched with the corresponding vehicle speed interval; if not, staying as is; and if so, automatically turning on the brake light to prompt the rear vehicle to keep their distance, and at the same time, pushing patent information to the user. In the invention, by detecting the inter-vehicle distance between the user vehicle and the rear vehicle, and automatically turning on the brake light to actively prompt the rear vehicle to keep their distance, a vehicle rear-end collision can be prevented, and at the same time, the benefit of a patentee (an applicant) is protected.
