Patent ID: 8468799

Claim:
A method of controlling an air supply system of a combustion engine, wherein an exhaust gas system arranged in the combustion engine includes an exhaust gas purification system with a particle filter, the method comprising: controlling a boost pressure of an air supply current in a combustion air supply duct via at least one of: a throttle valve; and an exhaust gas recirculation arranged between the exhaust gas system and the combustion air supply duct; evaluating the air supply current at one of: directly prior to a regeneration phase of the particle filter; and during the regeneration phase of the particle filter; wherein the air supply current is evaluated via : at least one signal of at least one measuring device arranged in the air supply system; and at least one signal of at least one measuring device arranged in the exhaust gas system; comparing a first result of the evaluation of the at least one signal of the at least one measuring device arranged in the air supply system and a second result of the evaluation of the at least one signal of the at least one measuring device arranged in the exhaust gas system; intervening a sequence control system for the regeneration of the particle filter upon a significant deviation of the first and second result; and performing a reasonability test of the air supply current via: calculating the air supply current by an injection amount, wherein the injection amount is deduced from a control unit for the fuel injection and from a lambda value of a lambda probe in an exhaust gas duct of the exhaust gas system; and calculating the air supply current from at least one signal of an air measurement system arranged in the air supply system.
