<p>Invention is related to systems which warn on vehicle drive speed changes. Its objective is to develop such vehicle breaking indication method which allows following in-front vehicle speed and speed changes, guaranteeing traffic safety, as well as to provide for device application without constructive changes in vehicle breaking system and vehicle itself. The set objective is achieved with transmission with the aid of signal converter of additional speed change signal to indication element which is designed as additional light panel and consists of, e.g., LEDs, and is located in vehicle's tailgate. Besides, additional light panel is completely (the whole area of the panel) lit before vehicle starts moving and with drive speed increase additional light panel gradually and symmetrically dims from centre to edges up to 1/4 of fully lit additional panel. When speed reaches 90 km/h light, remaining at this speed, is on constantly in both ends of the panel. With further speed increase it switches to intensive flash mode with flash frequency of, e.g., 211 per minute. Further speed increase leads to flash intensity decrease. When vehicle drive speed falls, process is reversed, i.e., flash intensity grows until reaches its maximum at 90 km/h, then switches to constant lighting in both ends of the panel. If drive speed keeps falling, additional light panel starts gradually and symmetrically lighting up in center direction until vehicle stops moving, when additional light panel is completely lit up.</p> |
