Verfahren zur Ermittlung der Querbeschleunigung eines Fahrzeugs

摘要

In order to find the transverse acceleration (QFZ) of a vehicle, especially as an input value for an electronic vehicle regulation system (ABS, ASR, EBV, etc.), the output signals from wheel sensors which reproduce the rotational behaviour of the individual vehicle wheels are evaluated. The correction factors are found which detect the differences in the tyre tread circumferences. A short and long non-term correction factor (KZ, LZ) are found for the non-driven vehicle wheels. The difference (DR1) between the long and short-term correction factors of the wheel concerned is found and evaluated in a filter and matching circuit (3). The quotient (KZ/LZ) of the short and long-term correction factors of the wheel concerned is calculated and the difference between the quotients of the left and right-hand non-driven wheels is found. The transverse acceleration of the vehicle (QFZ) is then found from the relation (I).
