Abstract

A method is for monitoring tire states and/or sensor states. The method includes the steps: a) capturing whether at least one tire sensor module for measuring tire states and/or sensor states is present in a monitoring region; b) determining whether the captured tire sensor module is unknown; c) evaluating data messages from the at least one captured and unknown tire sensor module, the evaluation including at least comparing at least one tire state transmitted via the data message with a limit value therefor and/or monitoring a sensor state of the tire sensor module transmitted via the data message; and, d) outputting a warning signal if a tire state exceeds or undershoots the respective limit value in order to indicate that a tire state of a tire assigned to the at least one unknown tire sensor module is critical and/or if a critical sensor state is detected.

Claims

1. A method for monitoring at least one of tire states and sensor states, the method comprising the steps of:

a)capturing whether at least one tire sensor module for measuring at least one of the tire states and sensor states is present in a monitoring region;

b) determining whether the at least one captured tire sensor module is unknown;

c) evaluating data messages (S1) from the at least one captured and unknown tire sensor module, the evaluation comprising at least one of comparing at least one tire state transmitted via a data message (S1) with a limit value (GW) therefor and monitoring a sensor state of the tire sensor module transmitted via the data message (S1); and

,

d) outputting a warning signal (S2) if at least one of;

one of said tire states exceeds or undershoots the respective limit value (GW) in order to indicate that a tire state of a tire assigned to the at least one unknown tire sensor module is critical;

a critical sensor state is detected;

determining whether the at least one captured and unknown tire sensor module belongs to a trailer vehicle of a driver'"'"'s own commercial vehicle;

monitoring a number of output data messages (S1) from the at least one captured and unknown tire sensor module in a period (dT) for the purpose of said determining whether at least one captured and unknown tire sensor module belongs to a trailer vehicle of a driver'"'"'s own commercial vehicle; and

,

wherein the data messages (S1) are already evaluated in step c) before it has been determined whether the at least one captured tire sensor module belongs to the driver'"'"'s own trailer vehicle.

2. A monitoring system for monitoring at least one of tire states and sensor states, the monitoring system comprising:

a control unit;

a receiving module;

said control unit being configured to capture, via said receiving module, whether at least one tire sensor module for measuring tire states is present in a monitoring region of said receiving module;

said control unit being further configured to determine whether the at least one captured tire sensor module is unknown to the control unit;

said control unit being further configured to evaluate a data message (S1) from the captured and unknown tire sensor module, said evaluation comprising at least comparing at least one tire state transmitted via the data message (S1) with a limit value (GW) therefor and/or monitoring a sensor state of the tire sensor module; and

,

said control unit being further configured to output a warning signal (S2) if at least one of;

a tire state exceeds or undershoots said limit value (GW) in order to indicate that a tire state of a tire assigned to the tire sensor module is critical,

there is a critical sensor state;

said control unit being also configured to determine whether a captured and unknown tire sensor module belongs to a trailer vehicle of a driver'"'"'s own commercial vehicle;

said control unit being configured to monitor a number of data messages (S1) output by the captured and unknown tire sensor module in a period (dT) for the purpose of determining whether a captured and unknown tire sensor module belongs to the trailer vehicle of the driver'"'"'s own commercial vehicle; and

,

said control unit being further configured to carry out the evaluation before it has been determined whether the captured tire sensor module belongs to the trailer vehicle of the driver'"'"'s own commercial vehicle.
