METHOD FOR ACQUIRING THE NUMBER OF USAGE TIMES OF VEHICLE REAR-END COLLISION-PROOF TECHNIQUE, AND BRAKE LIGHT SYSTEM

摘要

The invention belongs to the technical field of electronics, and provides a method for acquiring the number of usage times of a vehicle rear-end collision-proof technique, and a brake light system. The method comprises: recording an inter-vehicle distance threshold from the tail of a user vehicle to the head of a rear vehicle; detecting whether the inter-vehicle distance between the user vehicle and the rear vehicle is less than the inter-vehicle distance threshold from the tail of the user vehicle to the head of the rear vehicle; if not, staying as is; and if so, automatically turning on the brake light to prompt the rear vehicle to keep their distance, and sending technical usage data to a data collection end pre-set by a manufacturer. 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, it is convenient for the manufacturer to timely and effectively acquire utilisation conditions about the related technique.
