Abstract

The reference speed required for slip development is formed by using an auxiliary reference which specifies the reference slope during a sudden drop in wheel speed. In other circumstances, the speed of the second fastest wheel is included in the forming of a reference during the control action. In the absence of ABS control, the average speed of the non-driven wheels determines the reference speed. The change of reference speed forming from average value to use of the slope of the auxiliary reference and the speed of the second fastest wheel is made both at commencement of control action and even independently control action, when the sum of all wheel slips exceeds a threshold value a.
