Abstract

A control system for regulating operation of a first vehicle system includes first and second sensors that respectively monitor first and second operating parameters of a plurality of operating parameters, and a module that receives signals generated by the first and second sensors. The module accesses a look-up table that is normally provided to determine a first one of the plurality of operating parameters based on a second one of the plurality of operating parameters and an actual value of an input parameter. The module determines a virtual value of the input parameter while the actual value of the input parameter is equal to zero. At least one of the first and second vehicle systems is normally regulated based on the input parameter. The module regulates operation of the first vehicle system based on the virtual value of the input parameter.

Claims (30)

1. A control system for regulating operation of a first vehicle system, comprising:

first and second sensors that respectively monitor first and second operating parameters of a plurality of operating parameters; and

a module that receives signals generated by said first and second sensors that accesses a lookup table that is normally provided to determine a first one of said plurality of operating parameters based on a second one of said plurality of operating parameters and an actual value of an input parameter, that determines a virtual value of said input parameter while said actual value of said input parameter is equal to zero, wherein at least one of said first and second vehicle systems is normally regulated based on said input parameter, and that regulates operation of said first vehicle system based on said virtual value of said input parameter.

2. The control system of claim 1 wherein said module regulates operation by determining a second input parameter based on said virtual value of said input parameter, wherein said first vehicle system is regulated based on said second input parameter.

3. The control system of claim 1 wherein said input parameter is a pedal position.

4. The control system of claim 1 wherein said second vehicle system is an engine system, and said plurality of operating parameters include an engine speed and a throttle position.

5. The control system of claim 1 wherein said first vehicle system is a transmission, and wherein a gear ratio of said transmission is determined based on said virtual value.

6. The control system of claim 1 wherein said module determines said virtual value by interpolating said virtual value from said look-up table.

7. A method of regulating operation of a first vehicle system, comprising:

determining respective values of a plurality of operating parameters of a second vehicle system;

providing a look-up table to determine a first one of said plurality of operating parameters based on a second one of said plurality of operating parameters and an actual value of an input parameter;

determining a virtual value of said input parameter while said actual value of said input parameter is equal to zero, wherein at least one of said first and second vehicle systems is normally regulated based on said input parameter; and

regulating operation of said first vehicle system based on said virtual value of said input parameter.

8. The method of claim 7 wherein said regulating operation includes determining a second input parameter based on said virtual value of said input parameter, wherein said first vehicle system is regulated based on said second input parameter.

9. The method of claim 7 wherein said input parameter is a pedal position.

10. The method of claim 7 wherein said second vehicle system is an engine system, and said plurality of operating parameters include an engine speed and a throttle position.

11. The method of claim 7 wherein said first vehicle system is a transmission, and wherein a gear ratio of said transmission is determined based on said virtual value.

12. The method of claim 7 wherein said determining said virtual value includes interpolating said virtual value from said look-up table.

13. A method of regulating operation of a first vehicle system, comprising:

determining respective values of a plurality of operating parameters of a second vehicle system;

operating said second vehicle system in one of a first mode and a second mode;

determining a virtual value of an input parameter to said second vehicle system when operating in said first mode;

regulating operation of said first vehicle system based on said virtual value of said input parameter while said second vehicle system is operating in said first mode; and

regulating operation of said first vehicle system based on an actual value of said input parameter while said second vehicle system is operating in said second mode.

14. The method of claim 13 wherein said first mode is a cruise mode.

15. The method of claim 13 wherein said input parameter is a pedal position.

16. The method of claim 13 wherein said second vehicle system is an engine system, and said plurality of operating parameters include an engine speed and a throttle position.

17. The method of claim 13 wherein said first vehicle system is a transmission, and wherein a gear ratio of said transmission is determined based on said virtual value.

18. The method of claim 13 wherein said determining said virtual value includes interpolating said virtual value from a relationship based on said plurality of operating parameters.

19. The method of claim 18 further comprising providing said relationship as a look-up table that is used to determine a first one of said plurality of operating parameters based on a second one of said plurality of operating parameters and said actual value of said input parameter.
