Abstract
A display system for motor vehicles provides an array of lamps at the rear of a subject vehicle to provide an indication of the state of motion of the subject vehicle to the driver of a following vehicle. In a first mode of operation, the display indicates a level of warning dependent upon the rate of deceleration of the subject vehicle, the level of warning being determined by deceleration thresholds which are variable in dependence upon the measured speed of the subject vehicle. In a second mode of operation, the lamps provide an indication of the subject vehicle being stationary or near stationary as determined by comparing the measured speed with a threshold speed. An animate display is created by illuminating the lamps and sequentially deactuating selected pairs of lamps to create a pattern cyclically moving semetrically outwardly from the center of the row. The display is discontinued when the speed of the subject vehicle exceeds a second threshold defined independently of the first threshold speed. In a third mode of operation, the display indicates that the subject vehicle is stationary or near stationary in a manner which has less prominence, fewer lamps being illuminated, and in response to detection of a following vehicle being in close proximity to the subject vehicle.
