Abstract

A pseudo-tach signal system includes a pseudo-tach signal modeling module, and an output module operatively connected to the pseudo-tach signal modeling module. The output module exports a pseudo-tach signal based audible sound.

Claims (30)

1. A pseudo-tach signal system for an electric motor vehicle comprising:

a pseudo-tach signal modeling module; and

an output module operatively connected to the pseudo-tach signal modeling module, the output module exporting a pseudo-tach signal based audible sound representative of an operating condition of the electric motor vehicle.

2. The pseudo-tach signal system according to claim 1 , further comprising: a blending module including a blending model that synchronizes the pseudo-tach signal based audible sound with existing audible tones.

3. The pseudo-tach signal system according to claim 1 , further comprising: a storage module including one or more stored pseudo-tach signals.

4. The pseudo-tach signal system according to claim 1 , further comprising: a receiving module configured and disposed to receive one or more input signals from a motor vehicle.

5. The pseudo-tach signal system according to claim 4 , wherein the one or more input signals includes one of a speed signal, a torque signal, an accelerator pedal position signal, an acceleration signal, and a vehicle selected mode signal.

6. The pseudo-tach system according to claim 1 , further comprising: a speaker operatively connected to the output module, the pseudo-tach signal based audible sound being exported to the speaker.

7. A motor vehicle comprising:

a drivetrain including an electric motor and a transmission; and

a pseudo-tach signal system including:

a pseudo-tach signal modeling module; and

an output module operatively connected to the pseudo-tach signal modeling module, the output module exporting a pseudo-tach signal based audible sound representative of an operating condition of the electric motor.

8. The motor vehicle according to claim 7 , further comprising: a blending module including a blending model that synchronizes the pseudo-tach signal based audible sound with an existing audible signal generated by the drivetrain.

9. The motor vehicle according to claim 7 , further comprising: a storage module including one or more stored pseudo-tach signals.

10. The motor vehicle according to claim 7 , further comprising: a receiving module configured and disposed to receive one or more input signals from a motor vehicle.

11. The motor vehicle according to claim 10 , wherein the one or more input signals includes one of a speed signal, a torque signal, an accelerator pedal position signal, an acceleration signal, and a vehicle selected mode signal.

12. The motor vehicle according to claim 7 , further comprising: a speaker operatively connected to the output module, the pseudo-tach signal based audible sound being exported to the speaker.

13. A method of generating electric motor vehicle tones comprising:

receiving an acoustic signal indicator indicative of an operating condition of the electric motor vehicle;

generating a pseudo-tach signal associated with the acoustic signal indicator;

modeling a pseudo-tach signal based audible sound on the pseudo-tach signal; and

outputting the pseudo-tach signal based audible sound through a motor vehicle speaker.

14. The method of claim 13 , wherein generating the pseudo-tach signal based audible sound represents an audible signal that simulates an audible output of a rotating machine.

15. The method of claim 14 , wherein modeling the pseudo-tach based audible sound includes creating an artificial order signal that matches existing audible tones in the motor vehicle.

16. The method of claim 13 , wherein generating the pseudo-tach signal includes retrieving the pseudo-tach signal from a storage module.

17. The method of claim 16 , further comprising: storing a modeled pseudo-tach signal in the storage module.

18. The method of claim 13 , wherein receiving an acoustic signal indicator includes receiving one of one of a speed signal, a torque signal, an accelerator pedal position signal, an acceleration signal, and a vehicle selected mode signal.

19. The method of claim 13 , further comprising: blending the pseudo-tach signal based audible sound with existing audible motor vehicle tones.

20. The method of claim 13 , further comprising: amplifying the pseudo-tach signal based audible sound to be perceived externally of the motor vehicle.
