摘要： The present invention discloses a method of determining correction factors by which the different tire-tread circumferences are ascertained and compensated, wherein a short-time correction factor (KZ.sub.Rn) and a long-time correction factor (LZ.sub.RN) is developed for each wheel, the deviation (D.sub.Rn) of the short-time correction factor from the long-time correction factor is determined and the deviation is weighted by way of a band-pass filter (3), wherein subsequently a long-time average value (LM.sub.Rn) of the weighted deviation (D'Rn) is developed, and a partial value (TW.sub.Rn) of the long-time average value (LM.sub.Rn) is assessed, as a function of the driving condition, for the correction and adaption of the long-time correction factor (LZ.sub.Rn).

摘要： To determine the transverse acceleration of a vehicle, in particular as an input quantity for an electronic vehicle control system such as ABS, TCS, EBV, etc., the output signals of wheel sensors representative of the rotational behavior of the individual vehicle wheels are evaluated. The correction factors representing the differences of the tire tread circumferences of the individual wheels are determined. A short-time correction factor and a long-time correction factor KZ and LZ are produced in each case for the non-driven vehicle wheels. A difference between the long-time correction factor and the short-time correction factor of the respective wheel is determined and evaluated in a filtering and adapting circuit. The quotient KZ/LZ of the short-time correction factor and the long-time correction factor of the respective wheel is calculated, and the difference is produced between the quotients of the left and right non-driven ##EQU1## wheels. The transverse acceleration of the vehicle Q.sub.FZ is the result of the relation

摘要： The present invention describes a process for a vehicle including an electronic control system, which processes input signals representative of the rotational behavior of the individual wheels, and wherein the differences of the tire tread circumferences of the individual wheels are determined by way of short-time and long-time correction factors. The long-time correction factors LZ.sub.n. are determined from the differences D.sub.R1 between the short-time correction factors KZ.sub.R1 and the long-time correction factors LZ.sub.R1 of the respective wheel by averaging LM.sub.r1 the differences during a predetermined time interval and by evaluating and weighting the average value. For the quick identification of an emergency wheel, every time the vehicle engine is started, the long-time factor LZ.sub.R1 is equalled once to the short-time factor KZ.sub.R1 of the respective wheel, if simultaneously the short-time correction factors of three wheels are approximately equal and the short-time correction factor of the fourth wheel adopts a relatively high value, which is within a predetermined range, for a predetermined time interval or minimum time interval, and if the short-time correction factor of the fourth wheel remains approximately constant during this time interval.

摘要： For the reduction of disadvantageous effects of engine stall torques on the braking behavior of a vehicle which is equipped with a brake unit having an anti-lock control system, the brake slip of the driven wheels is monitored independently of any actuation of the brake. In the event of a rotational behavior of the driven wheels which is typical of the effect of engine stall torques, in particular in the event of a brake slip at the driven wheels exceeding a limit value, brake pressure existing in the wheel brakes of the driven wheels is maintained constant or reduced, or, if the braking action has not yet commenced, the supply of brake pressure into the wheel brakes of the driven wheels is prevented.
