Abstract
A vehicle display system has a stationary detector and an indicator, which form a stationary vehicle detection apparatus being operative to produce an indicator signal which is indicative of the vehicle being stationary. The vehicle display system also has a vehicle deceleration detector and an indicator. The vehicle deceleration detector measures the magnitude of deceleration of a vehicle and generates a signal to drive the indicator and thereby generate a display indicative of the magnitude of vehicle deceleration. The vehicle deceleration detector is independent of the vehicle braking system. In one embodiment, the indicator is an array of lamps and the stationary vehicle indicator signal is an inanimate display. One embodiment has an additional ranging device that detects a trailing vehicle within a predetermined distance of the vehicle employing the ranging device. The ranging device may be used to initiate a change of the display generated by the vehicle display system.
