Aid for a truck driver, alerting the need to replenish the exhaust gas cleaning reduction agent, displays the locations and routes to suitable petrol stations

摘要

The aid for a motor vehicle driver, who needs to replenish the exhaust cleaning reduction agent only at petrol stations where it is available, establishes which stations are located within range when it is low. A navigation system displays on a screen where the stations are located and the routes to them. The system also has a mobile communications function, for the driver to enquire if it is in stock and available. The amount in the tank is reserved to cover the distance to a refueling point.
