Digital message display for vehicles
First Claim
1. A digital message display for vehicles comprising:
- a message display capable of displaying short textual messages;
at least one short range distance sensor having a first sensing range, the at least one short range distance sensor being adapted for mounting to a rear surface of a vehicle;
at least one long range distance sensor having a second sensing range, the second sensing range being greater than the first sensing range, the at least one long range distance sensor being adapted for mounting to the rear surface of the vehicle;
a microcomputer in electrical connection with said message display and with said at least one vehicle distance sensor; and
a computer readable program code contained in said microcomputer, the program code having means for selectively reading a trailing vehicle distance from either of said at least one short range distance sensor or said at least one long range distance sensor, means for determining when the trailing vehicle distance falls below a safety threshold, and means for selectively displaying on said message display one of a plurality of predefined short textual messages when the trailing vehicle distance falls below said safety threshold.

Abstract
The digital message display for vehicles detects a tailgater and automatically flashes a warning message, directed to the tailgater, on a message display that is located in the rear window of the vehicle in view of following traffic. In addition to the warning message directed to the tailgater, a distance display is located in view of the vehicle driver to indicate the distance of the tailgater. An audible alarm alerts the driver to the presence of the tailgater. Additionally, a wireless remote control device allows the driver to manually select and display one of a number of pre-defined safety and courtesy messages. Multiple distance sensors provide multiple functional ranges to accommodate varying driving or traffic conditions.

14. A vehicle with a digital message display comprising:
-
a vehicle having a rear bumper; a message display capable of displaying short textual messages; at least one short range distance sensor having a first sensing range, the at least one short range distance sensor being mounted to the rear bumper of the vehicle; at least one long range distance sensor having a second sensing range, the second sensing range being greater than the first sensing range, the at least one long range distance sensor being mounted to the rear bumper of the vehicle; a microcomputer in electrical connection with said message display and with said at least one vehicle distance sensor; and a computer readable program code contained in said microcomputer, the program code having means for reading a trailing vehicle distance from either of said short range distance sensor and said long range distance sensor, means for determining when the trailing vehicle distance falls below a safety threshold, and means for selectively displaying on said message display one of a plurality of predefined short textual messages when the trailing vehicle distance falls below said safety threshold. - View Dependent Claims (15, 16, 17, 18, 19, 20)
