ABSTRACT:
A heads-up speed sensing display and control system for apprising an operator of the risk of operating a vehicle at various speeds has a risk indicator display with a plurality of illuminable elements, such as three different colored LEDs, illuminable in a plurality of patterns, each of the plurality of patterns having a predetermined correlation to vehicle speed, such as green for safe, yellow for caution and red for hazardous. A speed sensor, such as a Hall-effect device is coupled to a driven element of the vehicle, like a speedometer cable, and causes the speed sensor to generate a signal indicative of vehicle speed. A control unit receives the speed signal and selects an illumination pattern to indicate the risk of operation at the speed the vehicle is then traveling. The display may be wired or wireless and be attached to a windshield, face guard or helmet. The display system may be customizable to the operator and the environmental conditions and may be coordinated with a signage system using the same risk indicator conventions. The indicator system may also be used as a governor. In yet another embodiment, GPS data is used in a lookup table to ascertain the speed limit for the operation of the vehicle at any given time and place. The speed limit information is used to inform a governor which reduces vehicle speed to the ascertained limit. The ascertained speed limit may be used to select a risk indicator pattern for the actual operating speed of the device.
