  • Device and method for diagnosing brake and drive pull
    Patent number: 6859714
    Abstract: A device for a vehicle equipped with a wheel slip control system is described as having a determination device for determining first variables, each of which may be assigned to one wheel and/or the associated wheel brake. In addition, it includes a calculation device in which at least one second variable is calculated for at least one wheel axle of the vehicle from the first variables associated with the wheels of this wheel axle, this second variable being a measure of the difference between the first variables associated with this wheel axle. In addition, this device includes an averaging device in which a third variable is determined by averaging over time and/or filtering the at least one second variable, and it includes a comparator device which compares the value of the third variable with a preselectable limit value.
