Title: Procedure for drive slip control has brake force at controlled wheel decreased when at other, non-controlled wheel, wheel spin tendency is to be expected.
Inventor: WANDEL HELMUT
IPC: B60T8/175
Filed: 1998-08-19
Abstract: In a procedure for drive slip control, when there is an occurrence of a tendency for wheel spin at a wheel, this wheel is braked.
