PCT No. PCT/NO89/00029 Sec. 371 Date Oct. 9, 1990 Sec. 102(e) Date Oct. 9, 1990 PCT Filed Apr. 7, 1989 PCT Pub. No. WO89/09710 PCT Pub. Date Oct. 19, 1989.Systems and methods are described for achieving optimum braking/traction for a vehicle wheel (1), based upon measurement of road normal and road parallel force on the wheel axis (3). The measuring signals are continuously recorded in an electronic control unit (6) which undertakes running calculations for the friction coefficient of the wheel (1) against the ground (2), as well as the variation of the coefficient. The braking force, possibly the traction force is then altered in a continuous manner on the basis of the values of the friction coefficient and the variation thereof, in such a direction that optimum slip for the prevailing conditions is set rapidly, whereby optimum braking or traction is achieved.
