METHOD FOR CALIBRATING EXHAUST GAS PROBES AND FUEL DOSING DEVICES IN A HYBRID VEHICLE

摘要

In a method for calibrating a measuring signal of an exhaust gas probe or a control signal of a fuel dosing device of a vehicle equipped with a hybrid drive including an internal combustion engine and at least one electric motor, the vehicle being able to be driven also by an electric motor exclusively, the gas transport for calibrating the signal of the exhaust gas probe or the fuel dosing device is induced by an engine drag operation of the vehicle, in which the internal combustion engine is dragged by the at least one electric motor while the fuel supply is deactivated.
