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.
