Method and apparatus for operating a vehicle, in particular a watercraft
A method is provided for operating a vehicle, in particular a watercraft, with at least one combustion engine that emits pollutants contained in an exhaust gas or wastewater. The current position of the vehicle is determined by a location determination. A closed-loop and/or open-loop control device is provided which sets or adjusts the quantity of at least one pollutant emitted by the combustion engine in a self-acting manner or automatically, in accordance with the determined position of the vehicle and with information on local pollutant regulations, in particular exhaust and/or water regulations.
1. A method for operating a vehicle having at least one combustion engine that emits pollutants contained in at least one of an exhaust gas and wastewater, the method comprising:
determining a current position of the vehicle using a location determination system; and
adjusting, by a control device, a quantity of at least one pollutant emitted by the combustion engine selectively in accordance with the determined position of the vehicle and with information on local pollutant regulations,
wherein the step of adjusting includes adjusting or setting at least one parameter of an exhaust gas aftertreatment system of the vehicle, the parameter being at least one of a wastewater quantity passed through an exhaust gas scrubber of the exhaust gas aftertreatment system, a wastewater quantity passed into the body of water by the vehicle and the pH of the wastewater passed into the body of water by the vehicle.
2. The method according to claim 1 , wherein the step of adjusting is in accordance with a current vehicle speed, determined by a speed determination system, and a current vehicle direction of travel, determined by a direction of travel determination system.
3. The method according to claim 1 , further comprising at least one of storing information on the local pollutant regulations in the control device, communicating the information on the local pollutant regulations to the control device by at least one external information system, and communicating the current pollutant emissions of the vehicle to an external information system by the control device.
4. The method according to claim 1 , wherein the step of adjusting includes adjusting at least one component of the vehicle that affects the pollutant quantity of the combustion engine to one of a plurality of operating modes, wherein the pollutant quantity emitted by the combustion engine is different in each of the operating modes.
5. The method according to claim 1 , wherein the step of adjusting includes adjusting or setting at least one parameter of the combustion engine.
6. The method according to claim 5 , wherein the parameter is at least one of the combustion air ratio, the number of injections, the exhaust gas quantity recirculated by an exhaust gas recirculation system, an injection pressure, and an injection characteristic.
7. The method according to claim 1 , wherein the at least one parameter of the exhaust gas aftertreatment system of the vehicle further includes at least one of a combustion air ratio, a supplied reducing agent quantity for an SCR catalyst of the exhaust gas aftertreatment system, a regeneration of a particulate filter of the exhaust gas aftertreatment system, an exhaust gas flow through a bypass device of the exhaust gas aftertreatment system.
8. The method according claim 1 , wherein the step of adjusting includes adjusting or setting a type of fuel supplied to the combustion engine.
9. An apparatus for operating a vehicle having at least one combustion engine that emits pollutants contained in at least one of an exhaust gas and a wastewater, the apparatus comprising:
a location determination system by determining a current position of the vehicle;
a control device adjusting the quantity of at least one pollutant emitted by the combustion engine selectively in accordance with the determined position of the vehicle and with information on local pollutant regulations; and
an exhaust gas aftertreatment system with at least one further control device shiftable into a plurality of control positions, each of the positions and adjusts at least one parameter of the exhaust gas aftertreatment system which affects the pollutant quantity, wherein a shifting of the further control device is controlled by the control device, the at least one parameter being at least one of a wastewater quantity passed through an exhaust gas scrubber of the exhaust gas aftertreatment system, a wastewater quantity passed into the body of water by the vehicle and the pH of the wastewater passed into the body of water by the vehicle.
10. The apparatus according to claim 9 , further comprising a speed determination system determining a vehicle speed and a direction of travel determination system determining a vehicle direction of travel, wherein the quantity of at least one pollutant is adjusted by the control device in accordance with the determined current vehicle speed and the determined current vehicle direction of travel.
11. The apparatus according to claim 9 , wherein the control device includes at least one of:
a storage device, in which the information on the local pollutant regulations is stored; and
a transmitting and/or receiving device that at least one of receives the information on the local pollutant regulations from an external information system, and communicates the current pollutant emissions of the vehicle to an external information system.
12. The apparatus according to claim 9 , wherein the combustion engine has at least one further control device having a plurality of control positions, each of the positions and adjusts at least one parameter of the combustion engine which affects the pollutant quantity, wherein a shifting of the further control device is controlled by the control device.
13. The apparatus according to claim 9 , wherein the exhaust gas aftertreatment system includes at least one of a bypass device which guides or carries at least some of the exhaust gas flow past at least one exhaust gas aftertreatment element of the exhaust gas aftertreatment system, and the further control device is a valve device which adjusts or sets the exhaust gas flow through the bypass device and through the at least one exhaust gas aftertreatment element.
14. The apparatus according to claim 13 , wherein the at least one exhaust gas aftertreatment element is an SCR catalyst or a desulphurization device.
15. The apparatus according to claim 9 , further comprising a further control device that adjusts or sets a type of fuel supplied to the combustion engine, wherein the further control device is controlled by the control device.
16. A vehicle comprising a watercraft having an apparatus according to claim 9 .
