Abstract

An embodiment of the invention is an actuator controller for use in an actuator assembly. The actuator controller includes a processor for controlling an actuator associated with the actuator controller. A communication device is in communication with the processor. The communication device receives control commands from a master controller and is capable of communicating in multiple languages. A memory is accessible by the processor and the processor determines the language of the control commands and retrieves a control program from the memory corresponding to the language.

Claims

1. An actuator controller for use in an actuator assembly, the actuator controller comprising:

a processor for controlling an actuator associated with the actuator controller;

a communication device in communication with said processor, said communication device receiving at least one control command indicative of a commanded operational position of said actuator from a master controller, said communication device capable of communicating in multiple languages defined by the master controller;

a memory accessible by said processor; and

said processor accessing said memory to determine if a language identifier parameter is stored in said memory, said processor determining a language of said at least one control command based on said language identifier parameter if said language identifier parameter is stored in said memory, said processor determining said language of said control command in response to communication characteristics of said control command if said language identifier parameter is not stored in said memory.

2. The actuator controller of claim 1 wherein said language identifier parameter is stored in said memory upon calibration of said actuator.

3. The actuator controller of claim 1 wherein said processor is further configured to determine whether said communication device is receiving said at least one control command from said master controller.

4. The actuator controller of claim 3 wherein said processor is further configured to determine whether said at least one control command is a valid control command.

5. The actuator controller of claim 1 wherein said processor determining said language is performed repeatedly on a predetermined schedule.

6. The actuator controller of claim 1 wherein said language includes one of UART, CAN, PWM and analog communication techniques.

7. The actuator controller of claim 1, wherein said processor is further configured to induce an actuator shaft of said actuator to move to said commanded operational position based on said control command from said master controller.

8. The actuator controller of claim 1, wherein said master controller comprises an engine control module.

9. An actuator controller for use in an actuator assembly, the actuator controller comprising:

a processor for controlling an actuator associated with the actuator controller;

a communication device in communication with said processor, said communication device receiving at least one control command indicative of a commanded operational position of said actuator from a master controller, said communication device capable of communicating in multiple languages defined by said master controller; and

,

a memory accessible by said processor,

said processor being configured to determine a language of the control command based on either a language identifier parameter stored in said memory or a communication characteristic of said control command, said processor retrieving a control program from said memory corresponding to said language if said processor determines said language, said processor generating a default command position for said actuator upon failing to determine said language.

10. A method of automatically selecting a language for use with an actuator controller, the method comprising:

receiving at least one control command indicative of a commanded operational position of an actuator from a master controller;

determining a language of the control command;

and retrieving a control program corresponding to said language;

wherein the step of determining said language includes;

accessing a memory to determine if an language identifier parameter is stored in said memory;

determining said language of the control command based on said language identifier parameter if said language identifier parameter is stored in said memory; and

determining said language in response to communication characteristics of said control command if said language identifier parameter is not stored in said memory.

11. The method of claim 10 further comprising determining active receipt of said at least one control command when determining said language.

12. The method of claim 11 further comprising determining if said control command is valid when determining said language.

13. The method of claim 10 further comprising repeatedly determining said language on a predetermined schedule.

14. The method of claim 10 wherein said language includes one of UART, CAN, PWM and analog communication techniques.

15. A method of automatically selecting a language for use with an actuator controller, the method comprising:

receiving at least one control command indicative of a commanded operational position of an actuator from a master controller;

attempting to determine a language of the control command based on either a language identifier parameter stored in a memory or a communication characteristic of said control command;

retrieving a control program from the memory corresponding to said language if said language is determined; and

generating a default command position for said actuator upon failing to determine said language.
