Abstract
A method and systems are disclosed for controlling the exhaust emissions an internal combustion engine of a vehicle. The driving state of the vehicle is determined and corresponding driving state signals are generated with the aid of driving state detectors. The emission values of the exhaust gases emitted by the internal combustion engine are determined based on the driving state signals by a computer model stored in a control unit. The determined emission values are compared with predefined emission limits by the control unit. If the determined emission values exceed the predefined emission limits, the internal combustion engine and/or the exhaust aftertreatment device are controlled by the control unit such that the determined emission values are reduced until they lie below the predefined emission limits.

13. A method for controlling at least one of an internal combustion engine and an exhaust gas aftertreatment device of a vehicle comprising:
-
determining a driving state of the vehicle using at least one driving state detector; generating driving state signals based on the determined driving state; determining an emission value of exhaust gases emitted by the internal combustion engine based on the driving state signals and a computer model stored in a control unit; comparing the determined emission value to a predefined emission limit with the control unit; and controlling at least one of the internal combustion engine and the exhaust gas aftertreatment device with the control unit when the determined emission values exceed the predefined emission limits such that the determined emission values are reduced until they lie below the predefined emission limits. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
