Abstract Hydrogen is considered to be an ideal energy carrier for low-carbon vehicles in the near future. It canbe produced from water by using a variety of energy sources, such as solar, wind and nuclear, and itcan be converted into useful energy efficiently and without detrimental environmental effects. The onlyby-product is water or water vapour in fuel cell vehicles, but small amounts of NO x are produced incombustion systems. Hydrogen can be used in any application in which fossil fuels are being usedtoday, especially cars, buses and trucks. This paper considers how hydrogen can be combined with twoother technologies; online vehicle monitoring and computer maps to give significant reduction incarbon emissions from combustion engines, especially on trucks.

The first isonline monitoring of vehicle and driver performance throughsensors attached to the CANbus which controls all aspects ofthe subsystems’ operations, including engine, acceleration,braking, fuel consumption etc. [1]. The second is ADAS, theAdvanced Driver Assistance System (ADAS) developed byNAVTEQ [2]. This system is a map and positioning enginewhich uses a computer map of the vehicle’s surroundings(horizon data) plus a global positioning system to advise thedriver on approaching hills, traffic lights, curves and otherroad features which influence fuel consumption. NAVTEQalong with other companies have long recognized that digitalmaps can play a role as a ‘sensor’ that, when combined withother sensor inputs, can enable or support ADAS in a varietyof value-adding ways. To illustrate, road slope informationfrom the NAVTEQ map can inform a vehicle about upcominghills and support adjustments to the engine throttle accord-ingly. This ‘Predictive Cruise Control’ application is anexample of how maps can enable fuel savings within ADASby allowing the engine to run optimally and avoid driver in-efficiency. If hydrogen was also available to reduce carbonoutput from the truck, then three technologies could be com-bined to produce a substantial saving compared with currentfleet operations. First, we consider the CANbus monitoringsystem, then show how this can be combined with ADAS,and finally add in hydrogen to give further benefit.
