Abstract (en)

[origin: DE19735562A1] The method involves calculating a reference speed by measuring the wheel speeds of at least two wheels, but preferably all of the wheels. The speed may be calculated using a recursive calculation rule. Independent claims are also included for an equipment for determining the reference speed and for a data carrier storing the data or calculating program.
