Abstract
In a method for determining a pressure at the output of an exhaust gas system of an internal combustion engine system of a vehicle, a mass flow through the internal combustion engine system and an ambient pressure at a fresh air supply of the internal combustion engine system are detected. The pressure at the output of the exhaust gas system is determined as a function of the mass flow, the ambient pressure and throttling of the mass flow through the internal combustion engine system.
