Abstract
A method for the predictive operation of a fuel cell or a high-voltage accumulator, involving the steps of: detecting at least one external parameter, the at least one external parameter representing driving behavior data, navigation data and/or environmental data; and adjusting the at least one current desired fuel cell operating parameter on the basis of the at least one external parameter.
Claims19
A method for predictive operation of a fuel cell of a vehicle by a control unit of the vehicle programmed to execute the method, the method comprising the steps of:
- detecting at least one external parameter with a vehicle sensor system, wherein the at least one external parameter represents driving behavior information and/or navigation information of the vehicle;
- predicting, by the control unit, at least one future value of at least one operating parameter of the fuel cell, based on the at least one external parameter, while the fuel cell is currently operated to power the vehicle according to at least one current setpoint for the operating parameter of the fuel cell;
- and
- adapting, by the control unit, the current setpoint for the operating parameter of the fuel cell, on the basis of the predicted future value of the operating parameter of the fuel cell.
A method for operating a motor vehicle by a control unit of the vehicle programmed to execute the method, wherein the method comprises:
- detecting at least one external parameter with a vehicle sensor system, wherein the at least one external parameter represents driving behavior information and/or navigation information of the vehicle;
- predicting, by the control unit, at least one future value of at least one operating parameter of the fuel cell, based on the at least one external parameter, while the fuel cell is currently operated to power the vehicle according to at least one current setpoint for the operating parameter of the fuel cell;
- and
- adapting, by the control unit, the current setpoint for the operating parameter of the fuel cell, on the basis of the predicted future value of the operating parameter of the fuel cell.
