Abstract
A vehicle's operator can signal both the intended relative braking effort, and changes thereto, using a signal with a proportionately scaled and reactive display. A sensor measuring the current proportionate intensity of the intended and applied braking effort is attached to a vehicle's braking system. This sensor sends a signal to the associated external display (which may comprise multiple, separated areas). Each display area then shows that portion of its area commensurate with, or proportional to, the intensity of the intended and applied braking effort. The sensor, signal, and display(s) regularly repeat this at rapid intervals, thereby keeping the display responsive to and in accordance with the current intended and applied braking effort. In one enhancement, the outer limit of the display is activated when any braking effort is made, to enable rapid evaluation by any viewer between the relative effort applied and the potential full effort.
