Rear Brake Light System

摘要

An improved vehicle brake light system is provided, in which a transmitter and receiver is used to determine the distance and closing velocity of a trailing vehicle relative to a lead vehicle. The distance and closing velocity are used to determine whether a trailing vehicle may cause a risk of collision upon application of the lead vehicle brakes. If the distance between the trailing vehicle and lead vehicle is deemed below a minimum threshold at a given vehicle speed, the rear brake lights are illuminated. If the closing velocity is a trailing vehicle is deemed above a threshold maximum, the system pulses the rear brake lights of the lead vehicle. This improves communication between a lead vehicle and a trailing vehicle, whereby the trailing vehicle is alerted to cease tailgating activity or alternatively to apply the brakes in order to avoid a potential rear-end collision.

主权项

1. A vehicle brake light system, comprising:
a control unit comprising at least one microprocessor; at least one transmitter and receiver configured to be mounted to the rear of a lead vehicle; said transmitter and receiver configured to project signals rearward of said vehicle and determine a distance between said vehicle and a trailing vehicle; said control unit receiving electrical power from said lead vehicle and in electrical connection with one or more rear brake lights of said lead vehicle; said at least one microprocessor calculating closing speed of said trailing vehicle relative to said lead vehicle; said at least one microprocessor configured to pulse said one or more rear brake lights if said closing speed is above a defined threshold value.
