Abstract

Claims (30)

1 . A diagnostic system for verifying functionality and performing mapping of one or more wireless sensors in or on a wheel of a heavy-duty vehicle on an assembly line, the system comprising:

one or more assembly-line tools provided along the assembly line, each assembly-line tool comprising one or more antenna systems arranged to interrogate one or more wireless sensors integrated into or on a wheel of the vehicle, wherein each assembly-line tool is arranged in use to:

automatically locate on the vehicle and verify a function of the one or more wireless sensors; and

interrogate at least one of the one or more wireless sensors to perform a wireless sensor reading; and

pair sensor reading data with a tire identifier (ID),

pair sensor reading data with a vehicle chassis identifier (ID),

wherein the diagnostic system maps one or more wireless sensors using wireless sensor readings and provides mapping information for the one or more wireless sensors to a gateway/receiver of an electronic control unit of the vehicle.

2 . The diagnostic system of claim 1 , wherein the assembly line tool comprises a spindle tool configured to bolt vehicle wheels to a vehicle chassis or a wheel lift configured to lifting vehicle wheels onto an axle of a vehicle chassis.

3 . The diagnostic system of claim 1 , wherein the assembly line tool is configured to interrogate one or more axle position sensors on a vehicle wheel of a vehicle on the assembly line.

4 . The diagnostic system of claim 3 , wherein the assembly line tool is configured to interrogate one or more axle position, and stores data which pairs the axle position of the spindle-tool with the sensors detected at that location.

5 . The diagnostic system of claim 1 , wherein the assembly line tool is further configured to activate a diagnostic mode of a tire pressure and/or tire temperature sensor system of the vehicle on the vehicle assembly line.

6 . The diagnostic system of claim 1 , wherein one of the antenna systems provided on the assembly line tool comprises a plurality of low frequency antennas spaced around the assembly line tool so as to provide at least one antenna at a location sufficiently close to a tire pressure and temperature sensor to perform a reading of data provided by the tire pressure and sensor.

7 . The diagnostic system of claim 1 , wherein the data provided by the tire pressure/temperature sensor (TPS) includes a TPS identifier (TPS_ID).

8 . The diagnostic system of claim 1 , wherein the assembly line tool is configured to read one or more RFID tags located in a vehicle tire or wheel rim.

9 . The diagnostic system of claim 1 , wherein the assembly line tool configures each TPS_ID to be associated with a vehicle tire RFID and/or a vehicle chassis ID.

10 . The diagnostic system of claim 1 , wherein the assembly line tool stores data that pairs each TPS_ID with a vehicle tire RFID and/or with a vehicle chassis ID.

11 . An assembly-line tool for verifying functionality and performing mapping of one or more wireless sensors in a heavy-duty vehicle on an assembly line at assembly time, the tool comprising: one or more antenna systems arranged to interrogate one or more wireless sensors integrated into or on the vehicle, wherein the assembly-line tool is configured in use to:

automatically locate and verify a function of the one or more wireless sensors; and

interrogate at least one of the one or more wireless sensors to perform a wireless sensor reading;

pair sensor reading data with a tire identifier (ID); and

pair sensor reading data with a vehicle chassis identifier (ID),

send the wireless sensor reading to a diagnostic system configured to determine mapping information for the one or more sensors.

12 . The assembly line tool of claim 11 comprising a spindle tool configured to bolt vehicle wheels to a vehicle chassis or a wheel lift configured to lifting vehicle wheels onto an axle of a vehicle chassis and interrogate one or more axle position sensors on a vehicle wheel of a vehicle on the assembly line.

13 . The assembly line tool of claim 11 , wherein the tool is configured to interrogate one or more axle position sensors on a vehicle wheel of a vehicle on the assembly line, and stores data which pairs the axle position of the spindle-tool with the sensors detected at that location.

14 . The assembly line tool of claim 11 , wherein the tool is further configured to activate a diagnostic mode of a tire pressure and/or tire temperature sensor system of the vehicle on the vehicle assembly line.

15 . The assembly line tool of claim 11 , wherein one of the antenna systems provided on the spindle tool comprises a plurality of low frequency antennas spaced around the spindle tool so as to provide at least one antenna at a location sufficiently close to a tire pressure and temperature sensor to enable the spindle tool to:

perform a reading of data provided by the tire pressure and sensor, wherein the data provided by the tire pressure/temperature sensor (TPS) includes a TPS identifier, TPS_ID;

read one or more RFID tags located in a vehicle tire or wheel rim;

associate each TPS_ID with a vehicle tire RFID and/or a vehicle chassis ID; and

store, or send for storage on another apparatus, data pairing each TPS_ID with a vehicle tire RFID and/or with a vehicle chassis ID.
