Abstract

A method of identifying positions of brake monitors in relation to wheel brake units of a vehicle is provided. The brake monitors communicate by wireless to a control apparatus of the vehicle. The method includes steps of: (a) installing the brake monitors in association with the brake units; (b) individually or group-wise actuating the brake units in a sequence whilst monitoring corresponding brake unit actuations by using the brake monitors and generating corresponding brake unit actuation signals; (c) communicating the brake unit actuation signals from the brake monitors to the control apparatus; and (d) receiving the brake unit actuation signals at the control apparatus, and identifying from the received brake unit actuation signals positions whereat the brake monitors are installed on the vehicle. The method permits sequential actuation of the brake units and corresponding monitoring of associated signals generated by their brake monitors is capable of enabling installation positions of the brake monitors of being identified automatically.

Claims

1. A method of identifying positions of brake monitors in relation to wheel brake units of a vehicle, said brake monitors being operable to communicate by wireless to at least one control apparatus of the vehicle,

characterized in that said method includes steps of:

(a) installing said brake monitors in association with said brake units;

(b) individually or group-wise actuating said brake units in a sequence whilst monitoring corresponding brake unit actuations by using said brake monitors and generating corresponding brake unit actuation signals;

(c) communicating said brake unit actuation signals from said brake monitors to said at least one control apparatus; and

(d) receiving said brake unit actuation signals at said at least one control apparatus, and identifying from said received brake unit actuation signals positions whereat said brake monitors are installed on said vehicle.

2. A method as claimed in claim 1, wherein said method includes a step of providing each brake monitor with at least one identification code for use when communicating from said brake monitor to said at least one control apparatus, said at least one identification code enabling said brake monitor to be uniquely individually or group-wise identified by said at least one control apparatus when in communication therewith.

3. A method as claimed in claim 1 or 2, wherein each brake monitor is operable to monitor movement of at least one brake block of its corresponding brake unit during actuation of the brake unit.

4. A method as claimed in claim 1, 2 or 3, wherein said brake monitors are operable to function in a first hibernating state to conserve power, and a second active state for communicating an indication of actuation of their associated brake units, wherein switching between said first hibernating state and said second active state occurs for each brake monitor in association with actuation of its corresponding braking unit.

5. A method as claimed in any one of the preceding claims, wherein said brake monitors are coupled to actuators of their corresponding brake units which are operable to apply associated brake blocks, said brake monitors being mounted at locations spaced apart from said brake blocks for reducing exposure of said brake monitors to heat generated in said brake blocks when in operation.

6. A brake monitoring system for a vehicle, said system comprising at least one control apparatus and brake units which are susceptible to being individually or group-wise actuated in sequence, said system further comprising brake monitors coupled to said brake units for monitoring operation of said brake units, said brake units being coupled in communication with said at least one control apparatus of said system, wherein said system is operable to implement a method as claimed in any one of the preceding claims.

7. A software product stored on a data carrier, said software product being executable on computing hardware for performing a method as claimed in any one of claims 1 to 5.
