Abstract

A programming unit for TPMS sensors includes at least a microcontroller and memory storing at least a vehicle group database comprising multiple vehicle groups, each vehicle group comprising at least one vehicle, a version pair database comprising multiple version pair groups, each version pair group representing one vehicle group and comprising at least one version pair wherein each version pair includes an associated application version and an associated sub-application version, an application database comprising multiple application versions, each application version includes an associated binary file, and a sub-application database comprising multiple sub-application versions, each sub-application version includes an associated binary file.

Claims

1. A programming unit for TPMS sensors, the programming unit comprising:

at least one of a microcontroller and a microprocessor, and

non-volatile tangible memory storing at least one database, the memory comprising;

a vehicle group database that includes multiple vehicle groups, each vehicle group comprising a description of at least one vehicle;

a version pair database that includes multiple version pair groups, each version pair group representing one vehicle group and comprising at least one version pair, wherein each version pair comprises an associated application version and an associated sub-application version;

an application database that includes multiple application versions, each application version comprising an associated binary file;

a sub-application database comprising multiple sub-application versions, each sub-application version comprising an associated binary file.

2. The programming unit according to claim 1, wherein

the programming unit further comprises a binary file selector configured to select at least one of a binary file for an application version and a binary file for a sub-application version based on a selected vehicle.

3. The programming unit according to claim 2, wherein

the binary file selector is configured to select the binary file for the application version when a target TPMS sensor does not store, in operation, said binary file for the application version in the non-volatile tangible memory.

4. The programming unit according to claim 2, wherein

the binary file selector is configured to select the binary file for the sub-application when a target TPMS sensor does not store, in operation, said binary file for the sub-application version in said non-volatile tangible memory.

5. The programming unit according to claim 1, wherein

the programming unit comprises an application loader configured to request, from a TPMS sensor, at least one of an application version and an sub-application version of binary files stored in the non-volatile tangible memory.

6. A TPMS sensor configuration system comprising:

a programming unit according to claim 1, and

a tire-pressure monitoring sensor including at least a processing unit and a non-volatile memory storage, the non-volatile memory storage having executable code thereon, wherein the executable code comprises at least a bootloader configured to load at least one of an application version of a binary file and a sub-application version of the binary file into the non-volatile memory storage.

7. The TPMS sensor configuration system according to claim 6, wherein

the bootloader is configured to forward said at least one of the application version of the binary file and the sub-application version of the binary file stored in the non-volatile tangible memory to the non-volatile memory storage.

8. A method for configuring a tire-pressure monitoring sensor with a programming unit, the method comprising the following steps performed in the programming unit:

a) receiving at least one of a make and a model of a target vehicle from an input device,

b) extracting a vehicle group of the target vehicle from a vehicle group database,

c) if no vehicle group is found, displaying an error message and terminating the method,

d) extracting version pairs of the vehicle group from a version pair database,

e) transmitting a GET CHALLENGE command to the tire-pressure monitoring sensor and acquiring a reply from the tire-pressure monitoring sensor,

f) extracting from the reply a current application version and a current sub-application version in the tire-pressure monitoring sensor,

g) if the current application version exists in a version pair extracted in step d), proceeding with step k),

h) select a version pair, from the version pairs extracted in step d), that has the greatest application version from the extracted version pairs, and obtaining at least one of an associated application version and an associated sub-application version,

i) getting at least one of a binary version of an application from an application database and a binary version of a sub-application from a sub-application database based on said at least one of the application version and sub-application version,

j) loading at least one of the binary version of the application from the application database and the binary version of the sub-application from the sub-application database to the tire pressure monitoring sensor and proceeding with step n),

k) if the current sub-application version exists in a version pair extracted in step d), displaying a success message,

l) getting the binary version of the sub-application from the sub-application database based on the sub-application version of one of the version pairs, and

m) loading the binary version of the sub-application to the tire-pressure monitoring sensor.

9. The method according to claim 8, further comprising displaying a success message.
