Abstract: The present invention relates to a method of maintaining the effect of the engine brake of a vehicle during hill descent by way of an active, electronically controlled intervention of the brakes on at least one wheel. The present invention is characterized by a determination of the status of the wheels split into ‘stable wheels’ and ‘unstable wheels’ and the deceleration of all stable wheels (11 to 14) in the event of at least one unstable wheel, on which the condition Vunstable<Ki×Vref occurs, wherein Vunstable=speed of the unstable wheel Vref=medium wheel speed of the stable wheels Ki=correction factor (FIG. 2).

Abstract: In a cornering identification method which, in particular, is provided for automotive vehicles with anti-lock control or traction slip control, the rotating velocities of the two wheels of the one (non-driven) axle are measured and a correction value is continuously determined for the difference in the rolling circumferences of the tires of the two wheels. A reference value (THR) is developed which is representative of a straight-line course and, in accordance with a predetermined time pattern, this reference value is continuously corrected in dependence on the velocity difference of the two wheels. For cornering identification, a velocity difference value (DIF) is compared with the reference value (THR). At the beginning, i.e., after the start of cornering identification, the reference value (THR) will be corrected in relatively short periods which will be prolonged as the ride goes on. The rate of change (.DELTA. THR) of the reference value (THR) is likewise high at the beginning, decreasing thereafter.
