VEHICLE SYSTEM AND FUELLING APPROVAL METHOD (EMBODIMENTS) Russian patent published in 2019 - IPC G01C21/34 

FIELD: transportation.

SUBSTANCE: invention relates to the field of logistic control of vehicle refuelling processes. For this, taking into account the need to fill the tank with urea with respect to the need to fuel the tank during movement of the vehicle along the route, one or more alternative routes are proposed proceeding from the power reserve for the ending liquid. Proposed routes comprise filling stations, on which liquid can be filled. At that, filling of vehicles is matched in response to the order of liquid level reaching in the liquid tank for the outlet system of the minimum fluid threshold level for the exhaust system and fuel level in the fuel tank of the minimum fuel threshold level, determining one or more alternative routes containing a filling station, displaying said alternative routes to a vehicle driver through a display unit, wherein alternative driving directions are determined based on fuel consumption, fluid flow rate for the exhaust system and said order, generating, in response to driver selection of one of said alternative routes, vehicle navigation to a filling station indicated by a selected alternative route; and performing correction, in response to determination that vehicle travel margin is less than distance to filling station, operating parameter of engine to reduce engine power.

EFFECT: technical result is expansion of functional capabilities.
