The technology is the result of a 15-month collaborative research effort among Ricardo, Jaguar-Land Rover, TRL, Ordnance Survey and Orange Business Services, with partial funding provided by innovITS, a UK Centre of Excellence.

The project was aimed at cost-effectively reducing exhaust emissions and CO(2) output by extending the electronic horizon of the vehicle using internet-enabled mobile communications, GPS, advanced mapping and other sophisticated real-time navigational technologies.

"Sentience has been a unique partnership between three industries that would not normally work together," said Tom Robinson, Sentience project director, Ricardo.

"Through this collaboration, we've proven there is significant potential when onboard vehicle systems are connected with mobile communications and advanced-mapping technologies."

Through an advanced form of adaptive cruise control linked to the vehicle's hybrid powertrain system, a variety of information will calculate and determine an optimal driving strategy. Its control system adjusts vehicle speed, acceleration and deceleration.

Using GPS and mapping data, the system takes into account speed limits, traffic conditions, road gradient, bends and even speed bumps, as well as less predictable road features including traffic lights.

Data provided by mapping and navigational systems is also used to optimize the recharging strategy of a hybrid's batteries, increasing the potential availability of electric-only mode in urban environments.

Although not implemented on the project vehicle, the Enhanced Acceleration/Deceleration implementation has the necessary links to work with real-time traffic information to update its strategy according to prevailing conditions and areas of congestion.

In track-based tests, the EAD strategy has demonstrated fuel savings of between 5 and 24 percent depending on traffic conditions and route topology.
