Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for calibrating a measuring signal of an exhaust gas probe of a vehicle equipped with a hybrid drive having an internal combustion engine and at least one electric motor, wherein the vehicle is able to be selectively driven exclusively by the at least one electric motor, comprising: inducing, by an engine drag operation of the vehicle, a gas transport for calibrating the measuring signal of the exhaust gas probe, wherein in the engine drag operation…
