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, 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, each task including one or more subtasks, each subtask including subtask-specific triggering logic for execution of one or more actions based on the triggering logic, wherein the triggering logic is based on modular condition blocks.

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

8. A non-transitory computer-readable medium, part of a telematics unit, 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:

determining, by a 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 evaluates to TRUE; and

performing the one or more actions.

9. The non-transitory computer-readable medium of claim 8, 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.

10. The non-transitory computer-readable medium of claim 8, 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.

11. The non-transitory computer-readable medium of claim 10, 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.

12. The non-transitory computer-readable medium of claim 8, wherein at least one of the modular condition blocks is used in more than one subtask.

13. The non-transitory computer-readable medium of claim 8, wherein at least one of the modular condition blocks is used in more than one task.

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

determining, by a 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 evaluates to TRUE; and

performing the one or more actions,

15. The method of claim 14, further comprising:

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

16. The method of claim 14, 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.

17. The method of claim 16, 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.

18. The method of claim 14, wherein at least one of the modular condition blocks is used in more than one subtask.

19. The method of claim 14, wherein at least one of the modular condition blocks is used in more than one task.
