A new cruise control system which uses GPS to determine the position of a vehicle and then forecast of the topography of the road ahead has been developed by Scania. The vehicle’s cruising speed will then be adjusted before it enters an ascent or descent, thus helping the driver to get the best possible fuel economy.
This system can deliver a saving on fuel of up to 3% when you are driving on stretches of road which are undulating. Called the Scania Active Prediction, this system is a milestone in the systematic focus which Scania are putting on drivers by helping them to both save fuel and reduce their impact on the environment.
It is completely intuitive and adapts the drivers style to the predicted topography is much the same way as the most highly skilled HGV drivers would do. The system also assists experienced drivers to save fuel while driving under inclement weather conditions, in the dark, or on new routes.
The time factor is often a high priority in transport services and there is a price to pay for this in terms of higher fuel consumption. Scania’s new cruise control system has been developed to help drivers get to their destination in time without wasting fuel.
The Scania Active Prediction cruise control system contributes to fuel savings of up to 3 percent with minimal time loss, compared to highway or motorway driving with normal cruise control. Maximum benefits are gained on an undulating route, where the road is never entirely flat.
The time lost in a full day’s driving is merely a couple of minutes, which for the great majority of transport companies is marginal compared to the financial and environmental benefits.
Based on a 40-tonne truck combination (tractor unit and semitrailer) running 180,000 km/year, a fuel saving of 3 percent would reduce fuel consumption by about 1,700 litres per year. This is equivalent to an annual reduction in fuel costs of almost SEK 20,000 (EUR 2,200) and a reduction in carbon dioxide emissions of over 4 tonnes.
Scania will start to deliver trucks with the Active Prediction system to customers starting next year. There is topographic map data available today for around 95% of the road network in central and western Europe, which is also useful for operators that provide transit services from eastern Europe,Turkeyand beyond.
