Abstract

A telematics unit is provided. The telematics unit includes a non-transitory computer-readable medium and a processor, configured to execute a telematics task manager application according to processor-executable instructions stored on the non-transitory computer-readable medium. The telematics task manager application comprises a plurality of tasks. Each task includes one or more subtasks. Each subtask including subtask-specific triggering logic for execution of one or more actions based on the triggering logic. The triggering logic is based on modular condition blocks.

Claims

1. A telematics unit of a telematics-equipped vehicle, comprising:

a non-transitory computer-readable medium;

a processor, configured to execute a telematics task manager application according to processor-executable instructions stored on the non-transitory computer-readable medium;

wherein the telematics task manager application comprises a plurality of tasks and a plurality of modular condition blocks, wherein each task includes one or more subtasks, each subtask includes subtask-specific triggering logic for execution of one or more actions based on the triggering logic, and the triggering logic is based on the plurality of modular condition blocks;

wherein the telematics task manager application is configured to communicate with vehicle sensors and control modules of the telematics-equipped vehicle to determine whether sensed conditions of the telematics-equipped vehicle corresponding to the plurality of modular condition blocks are met, wherein the conditions include conditions relating to;

a powertrain status, and

an ignition status, and

wherein a sensed condition of the telematics-equipped vehicle relating to the powertrain status corresponds to a diagnostic trouble code (DTC), and wherein a sensed condition of the telematics-equipped vehicle relating to the ignition status corresponds to whether the vehicle ignition is being run.

2. The telematics unit of claim 1, wherein each task further includes a task storage buffer.

3. The telematics unit of claim 1, wherein the processor is configured to execute the one or more actions if the triggering logic evaluates to TRUE based on a Boolean relational formula utilizing the modular condition blocks.

4. The telematics unit of claim 3, wherein the Boolean relational formula defines a relationship between the modular condition blocks using at least one of an AND, THEN, OR, or NOT operator.

5. The telematics unit of claim 4, wherein the Boolean relational formula defines the relationship between the modular condition blocks using a combination of at least two of the AND, THEN, OR, or NOT operators.

6. The telematics unit of claim 1, wherein at least one of the modular condition blocks is used in more than one subtask.

7. A non-transitory computer-readable medium, part of a telematics unit of a telematics-equipped vehicle, having processor-executable instructions thereon for controlling operation of the telematics unit, the processor-executable instructions, when executed by a processor, causing the following steps to be performed:

communicating, by a telematics task manager application of the telematics unit, with vehicle sensors and control modules of the telematics-equipped vehicle to determine whether sensed conditions of the telematics-equipped vehicle corresponding to a plurality of modular condition blocks are met, wherein the conditions include conditions relating to;

a powertrain status, and

an ignition status;

determining, by the telematics task manager application, that subtask-specific triggering logic indicates that one or more actions is to be performed, wherein the determination further comprises determining that a Boolean relational formula utilizing modular condition blocks of the plurality of modular condition blocks evaluates to TRUE; and

performing the one or more actions,

wherein a sensed condition of the telematics-equipped vehicle relating to the powertrain status corresponds to a diagnostic trouble code (DTC), and wherein a sensed condition of the telematics-equipped vehicle relating to the ignition status corresponds to whether the vehicle ignition is being run.

8. The non-transitory computer-readable medium of claim 7, wherein the processor-executable instructions further cause the following step to be performed:

storing, by the telematics task manager application, task-related data to a task storage buffer.

9. The non-transitory computer-readable medium of claim 7, wherein the Boolean relational formula defines a relationship between the modular condition blocks using at least one of an AND, THEN, OR, or NOT operator.

10. The non-transitory computer-readable medium of claim 9, wherein the Boolean relational formula defines the relationship between the modular condition blocks using a combination of at least two of the AND, THEN, OR, or NOT operators.

11. The non-transitory computer-readable medium of claim 7, wherein at least one of the modular condition blocks is used in more than one subtask.

12. A processor-implemented method for controlling operation of a telematics unit of a telematics-equipped vehicle, the method comprising:

communicating, by a telematics task manager application of the telematics unit, with vehicle sensors and control modules of the telematics-equipped vehicle to determine whether sensed conditions of the telematics-equipped vehicle corresponding to a plurality of modular condition blocks are met, wherein the conditions include conditions relating to;

a powertrain status, and

an ignition status;

determining, by the telematics task manager application executed by a processor of the telematics unit, that subtask-specific triggering logic indicates that one or more actions is to be performed, wherein the determination further comprises determining that a Boolean relational formula utilizing modular condition blocks of the plurality of modular condition blocks evaluates to TRUE; and

performing the one or more actions,

wherein a sensed condition of the telematics-equipped vehicle relating to the powertrain status corresponds to a diagnostic trouble code (DTC), and wherein a sensed condition of the telematics-equipped vehicle relating to the ignition status corresponds to whether the vehicle ignition is being run.

13. The method of claim 12, further comprising:

storing, by the telematics task manager application, task-related data to a task storage buffer.

14. The method of claim 12, wherein the Boolean relational formula defines a relationship between the modular condition blocks using at least one of an AND, THEN, OR, or NOT operator.

15. The method of claim 14, wherein the Boolean relational formula defines the relationship between the modular condition blocks using a combination of at least two of the AND, THEN, OR, or NOT operators.

16. The method of claim 12, wherein at least one of the modular condition blocks is used in more than one subtask.
