摘要： A process is disclosed for a vehicle with an electronic regulation system that processes input signals that represent the rotational behaviour of individual wheels, and that detects differences between the type tread circumferences of the individual wheels by means of short time and long time correction factors. Long time correction factors (LZn) are derived from the differences (DR1) between short time (KZR1) and long time correction factors (LZR1) of each wheel by averaging (LMR1) said differences during a predetermined time interval and by evaluating and weighting the thus obtained average value. In order to quickly recognise an emergency wheel, every time the vehicle engine is started the long time factor (LZR1) is equalled once to the short time factor (KZR1) of each wheel. The emergency wheel is recognised when the short time correction factors of three wheels are approximately equal at the same time, when the short time correction factor of the fourth wheel takes a relatively high value within a predetermined range during a predetermined time interval or minimum time interval, and when the short time correction factor of the fourth wheel remains approximately constant during this time interval.

摘要： A process is disclosed for determining correction factors that detect and compensate for different tire tread circumferences. A short-term correction factor (KZRn) and a long-term correction factor (LZRn) are formed for each wheel, the deviation (DRn) between short-term and long-term correction factors is determined, this deviation is weighted by means of a band-pass filter (3), then a long-term average value (LMRn) of the weighted deviation (D'Rn) is calculated and a partial value (TWRn) of said long-term average value (LMRn) is evaluated to correct and adapt the long-term correction factor (LZRn) depending on driving conditions.

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).

摘要： In order to reduce undesired effects of motor drag moments (MSM) on the braking behaviour of a motor vehicle fitted with an anti-lock braking system, the braking slip (μ1,2) of the driven wheels is detected independently of any brake actuation. With a rotation behaviour of the driven wheels (VL, VR) which is typical for the action of motor drag moments (MSM), especially with a brake slip (μ1,2) at these wheels (VL, VR) above a limit, the braking pressure in the wheel brakes of the driven wheels (VL, VR) is kept constant or reduced or, if the braking process has not yet begun, the control of braking pressure into the wheel brakes of the driven wheels is eliminated.

摘要： Afin de réduire les effets indésirables de couples de freinage d'un moteur (MSM) sur le comportement au freinage d'un véhicule, équipé d'un système de freinage antiblocage, le glissement au freinage (lambda1,2) des roues entraînées est déterminé indépendamment de tout actionnement des freins. Lors d'un comportement de rotation des roues entraînées (VL, VR), caractéristique de l'apparition de couples de freinage du moteur (MSM), notamment lors d'un glissement au freinage (lambda1,2) au niveau desdites roues entraînées (VL, VR) dépassant une valeur limite, la pression de freinage présente dans les freins des roues entraînées (VL, VR) est maintenue constante ou est réduite, ou bien si le freinage n'a pas encore débuté, l'injection de pression de freinage dans les freins des roues entraînées est supprimée.
