Abstract
A method and a device for evaluating a sensor signal. A value for the residual braking torque of the brake and/or a detection of a blockage of the wheel brake is derived as a function of this signal in the unbraked state.
Claims17
A method for evaluating a sensor signal which represents a braking torque applied to at least one wheel, as a function of which a wheel brake assigned to the at least one wheel is controlled, the method comprising the step of:
- as a function of the sensor signal, performing at least one of the following:
- determining a residual braking torque during unbraked driving;
- and
- detecting a mechanical blockage in an area of the wheel brake.
1 more element
A device for evaluating a sensor signal comprising:
- a control unit for receiving a signal representing a braking torque on at least one wheel and for transmitting an output signal for controlling at least one wheel brake as a function of the braking torque signal;
- and
- means for performing, depending on the braking torque signal, at least one of (a) determining a residual braking torque during unbraked driving and (b) detecting a malfunction of the wheel brake.
