Patent ID: 6859714

Claim:
A device for detecting one of a pull brake and a pull drive of a vehicle equipped with a wheel slip control system, comprising: a determination device for determining first variables, each assignable to one of a wheel and an associated wheel brake; a calculation device for calculating at least one second variable for at least one wheel axle of the vehicle from a set of the first variables associated with wheels of the at least one wheel axle, the at least one second variable being a measure of a difference between the set of the first variables associated with the at least one wheel axle; an averaging device for determining a third variable by at least one of averaging over time and filtering the at least one second variable for a period of time such that the third variable determined there is a measure of a difference between values of the set of the first variables associated with the at least one wheel axle, the difference being not due to an intervention by the wheel slip control system; and a comparator device for comparing a value of the third variable with a preselectable limit value.
