Abstract

An apparatus, method, and system for controlling the torque of an internal combustion engine during certain vehicle component operations to minimize unwanted motion and vibration. The method includes detecting at least one of reverse gear engagement or reverse movement of the vehicle; wherein a feedback control of the internal combustion engine is switched from open-loop control to closed-loop control upon detection of at least one of a reverse gear activation or reverse movement of the vehicle.

First claim

What is claimed is:

1. A method for controlling the torque of an internal combustion engine of a vehicle comprising:
detecting at least one of a reverse gear activation or a reverse movement of the vehicle; wherein feedback control of the internal combustion engine is switched from open-loop control to closed-loop control upon detection of at least one of a reverse gear activation or a reverse movement of the vehicle
detecting an engine temperature, wherein the engine torque control is switched from the open-loop control to the closed-loop control once the engine temperature is determined to equal or exceed a threshold value.

2. The method for controlling the torque of an internal combustion engine of claim 1 , wherein an engine temperature is determined based on an engine coolant temperature.

3. The method for controlling the torque of an internal combustion engine of claim 1 wherein the closed-loop control adjusts torque based on mapping data comprising at least one of an intake air amount, a fuel intake amount, and a detected engine speed.

4. The method for controlling the torque of an internal combustion engine of a vehicle of claim 1 , wherein an engine torque is controlled by adjusting at least one of an intake throttle plate position and an engine ignition timing.

5. The method for controlling the torque of an internal combustion engine of a vehicle of claim 1 , wherein when the torque is controlled using the open-loop control, at least one of an intake throttle plate position, and an engine ignition timing based on data stored in a memory of a powertrain control module.

6. A system for controlling the torque of an internal combustion engine of a vehicle comprising: a control module having a memory and a processor, wherein the control module is capable of controlling an engine output torque at idle, the control module determining at least one of a reverse gear activation or a reverse movement of the vehicle; wherein the control module is configured to switch feedback control of the engine torque from open-loop control to closed-loop control upon detection of at least one of a reverse gear activation or a reverse movement of the vehicle
determining an engine temperature at the control module, wherein the control module switches the engine torque control from the open-loop control to the closed-loop control once the engine temperature is determined to equal or exceed a threshold value.

7. The system for controlling the torque of an internal combustion engine of claim 6 , wherein an engine temperature is determined based on an engine coolant temperature.

8. The system for controlling the torque of an internal combustion engine of claim 6 wherein during a closed-loop control, the control module adjusts torque based on mapping data comprising at least one of an intake air amount, a fuel intake amount, and a detected engine speed.

9. The system for controlling the torque of an internal combustion engine of a vehicle of claim 6 , wherein the control module adjusts the engine torque by adjusting at least one of an intake throttle plate position and an engine ignition timing.

10. The system for controlling the torque of an internal combustion engine of a vehicle of claim 6 , wherein when the torque is controlled using the open-loop control, the control module adjusts at least one of an intake throttle plate position and an engine ignition timing based on data stored in a memory.

11. A computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out a method for controlling an idle torque of an internal combustion engine, the method comprising: detecting at least one of a reverse gear activation or a reverse movement of the vehicle; wherein feedback control of the internal combustion engine is switched from open-loop control to closed-loop control upon detection of at least one of; a reverse gear activation; or a reverse movement of the vehicle
detecting an engine temperature, wherein the engine torque control is switched from the open-loop control to the closed-loop control once the engine temperature is determined to equal or exceed a threshold value.

12. The computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out a method for controlling an idle torque of an internal combustion engine of claim 11 , wherein an engine temperature is determined based on an engine coolant temperature.

13. The computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out a method for controlling an idle torque of an internal combustion engine of claim 11 , wherein the closed-loop control is used to adjust torque based on mapping data comprising at least one of an intake air amount, a fuel intake amount, and a detected engine speed.

14. The computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out a method for controlling an idle torque of an internal combustion engine of claim 11 , wherein an engine torque is controlled by adjusting at least one of an intake throttle plate position and an engine ignition timing.

15. The computer-readable storage medium comprising instructions which, when executed by a computer, cause the computer to carry out a method for controlling an idle torque of an internal combustion engine of claim 11 , wherein when the torque is controlled using the open-loop control, at least one of an intake throttle plate position and an engine ignition timing is controlled based on data stored in a memory of a powertrain control module.
