Authenticated Sensor Interface Device

Engineers at Savannah River National Laboratory (SRNL) are working on development of a new method for providing feedback to drivers of vehicles in order to maximize fuel efficiency through improved driving habits.


Today’s vehicles provide feedback to the driver on a wide variety of vehicle or driver characteristics. Some of the information provided includes speed, temperatures, tire pressure, radio, GPS, cell phone controls, trip monitors and fuel consumption. The majority of the current systems are visual, providing data on an already crowded instrument cluster. In order to realize the benefits of this information, drivers have to consciously take their eyes off the road to view the data. The more frequently the data is reviewed, the better drivers can adjust to changing conditions; however, doing so can take a driver’s attention away from operating the vehicle in a safe manner. Studies have shown that differences in driving style can cause a 20 percent variation in fuel economy, making improvements in driver feedback an area that can realize significant real world fuel economy gains.

Using a seat equipped to provide non-visual feedback to the driver enables the presentation of continuous, real-time information on fuel economy without having to divert attention from traffic and road conditions.
