Gear change recognition procedure for car, after gear change, has engine load and engine speed determined with engagement recognized when engine speed begins to rise with no engine load present

摘要

A procedure for the recognition of whether a gear of a car, and which one, is engaged after a gear change has for the recognition at least the engine load and the engine speed determined and linked together. The engagement of a gear after a gear change between two gears is recognized when the engine speed begins to rise with a small value and at the same time, no engine load is present. The engaged gear after a gear change between two gears is determined by the temporal change of the ratio of the vehicle speed to the engine speed being determined and from here on determined by an extrapolation to the gear.
