Abstract
A warning display system for vehicles, comprising a light projection system that is mounted on a rear region of a leading vehicle capable of traversing a road surface forwardly to a trailing vehicle and that is configured to project emitted light onto the road surface so as to generate a warning image visible to a driver of the trailing vehicle externally to the trailing vehicle, when the trailing vehicle approaches the leading vehicle at a distance less than predetermined proximity corresponding to a given speed of the trailing vehicle, of the leading vehicle and the acceleration of the distance between them.
Claims20
A warning display system for vehicles, comprising electronic equipment configured for displaying a warning image visible to a driver of a trailing vehicle, the electronic equipment mounted on a rear region of a leading vehicle;
- wherein the system is configured to generate the warning image when the trailing vehicle approaches the leading vehicle at a distance less than a predetermined proximity, the predetermined proximity being dynamically determined based on the speed of the trailing vehicle, the speed of the leading vehicle, and the acceleration of the distance between them;
- the system further comprising a time-of-flight (TOF) system including a sensor and a processor configured to determine an instantaneous distance between the vehicles and a corresponding proximity severity level, and a short-range transmitter configured to transmit a signal representative of the proximity severity level to a controller;
- wherein the controller is configured to command operation of the electronic equipment in response to the transmitted signal;
- and
- wherein an appearance of the warning image is indicative of the proximity severity level, and a length and/or position of the warning image is dependent upon the speeds of the vehicles and the proximity.
A method of warning a trailing vehicle, comprising:
- generating, by electronic equipment mounted on a rear region of a leading vehicle, a warning image visible to a driver of the trailing vehicle;
- measuring an instantaneous distance between the vehicles with a time-of-flight sensor and processing signals with a processor to determine a proximity severity level as a function of the speeds of the vehicles and the acceleration of the distance between them;
- transmitting a short-range signal representative of the proximity severity level to a controller;
- and
- commanding operation of the electronic equipment in response to the transmitted signal such that an appearance of the warning image is indicative of the proximity severity level, and a length and/or position of the warning image is dependent upon the vehicles' speeds and proximity, the warning image being generated when the trailing vehicle approaches the leading vehicle at a distance less than the predetermined proximity.
A warning display system for vehicles, comprising a display screen that is combined with a light projection system to form a console adapted to replace its rear vehicle registration plate, the console being configured to display a warning image visible to a driver of a trailing vehicle when the trailing vehicle approaches the leading vehicle at a distance less than a predetermined proximity determined as a function of the speeds of the vehicles and the acceleration of the distance between them;
- the system further comprising a time-of-flight system including a sensor, a processor configured to determine an instantaneous distance and a proximity severity level, and a short-range transmitter configured to transmit a signal representative of the proximity severity level to a controller that commands operation of the console in response to the transmitted signal;
- and
- wherein an appearance of the warning image is indicative of the proximity severity level and a length of the warning image is dependent upon the speeds of the vehicles and the proximity.
The system of claim 19, wherein the console is configured to operate in two modes, including a default mode and a warning mode, wherein in the default mode the console displays a vehicle registration number and in the warning mode the console displays a safety warning image or message, wherein the console automatically switches from the default mode to the warning mode when the trailing vehicle approaches the leading vehicle at a distance less than the predetermined proximity.
