Method and device for the drive control of a motor vehicle so as to prevent undesirable spinning of the driven vehicle wheels

摘要

The invention relates to a method for the drive control of a motor vehicle so as to prevent undesirable spinning of the driven vehicle wheels, in which only one of the wheel brakes is activated or the engine torque is reduced, as necessary. In this method, the excess torque causing the wheel to spin is repeatedly calculated for each driven wheel in the manner of an adaptive control from measured speeds and stored vehicle and engine data according to the relationship Mü = theta <*> . DELTA omega , and then the reduced torque necessary to rectify the spinning/tendency to spin, according to the relationship Mred = Mü + k ( DELTA omega - s), and applied in correct proportions as braking torque and/or as reduced engine torque, depending on the driving situation at any time. <IMAGE>
