Abstract

A wireless turbo boost controller, a computer program product for operating a wireless turbo boost controller in a turbo system of a vehicle, and a turbo boost control system for a vehicle are provided herein. In one embodiment, the wireless turbo boost controller includes: (1) a wireless communication module, (2) an input interface configured to receive a pressure signal indicative of a manifold pressure of an engine of the vehicle and a RPM signal indicative of an RPM of the engine of the vehicle, and (3) a processor configured to control the wastegate solenoid of the turbo system based on the pressure signal, the RPM signal, and at least one program setting received via the wireless communication module.

Claims

1. A wireless turbo boost controller configured to control a wastegate solenoid of a turbo boost control system of a vehicle, the wireless turbo boost controller comprising:

a wireless communication module;

an input interface configured to receive a pressure signal indicative of a manifold pressure of an engine of the vehicle and a RPM signal indicative of an RPM of the engine of the vehicle; and

a processor configured to control the wastegate solenoid of the turbo system based on the pressure signal, the RPM signal, and at least one program setting received via the wireless communication module.

2. The wireless turbo boost controller of claim 1 wherein the processor is configured to control the wastegate solenoid by changing a duty cycle of a solenoid control signal based on the manifold pressure such that:

when the manifold pressure is less than a wastegate spring pressure of a wastegate of the turbo boost control system, the processor sets the duty cycle to 100%; and

when the manifold pressure is greater than the wastegate spring pressure but less than an overboost threshold pressure, the processor sets the duty cycle to a setpoint duty cycle received via the wireless communication module.

3. The wireless turbo boost controller of claim 2 wherein the processor is configured to set the duty cycle to 100% when the manifold pressure is less than the wastegate spring pressure and is greater than one, and tests the solenoid when the manifold pressure is less than one.

4. The wireless turbo boost controller of claim 3 wherein the processor is further configured to shut down the solenoid when the manifold pressure is greater than the overboost threshold pressure.

5. The wireless turbo boost controller of claim 2 wherein the wireless turbo boost controller receives the setpoint duty cycle while the vehicle is moving and the processor controls the wastegate solenoid with the setpoint duty cycle in real time while the vehicle is moving.

6. The wireless turbo boost controller of claim 2 wherein the wireless turbo boost controller receives the setpoint duty cycle via the wireless communication module from a mobile computing device during a user defined time period.

7. The wireless turbo boost controller of claim 6 wherein the wireless communication module is configured to send a solenoid status signal to the mobile communication device.

8. The wireless turbo boost controller of claim 6 wherein the wireless communication module is configured to send a vehicle battery status signal to the mobile communication device.

9. The wireless turbo boost controller of claim 6 wherein the wireless communication module is further configured to receive a sensitivity setting from the mobile computing device.

10. The wireless turbo boost controller of claim 6 wherein the wireless turbo boost controller is configured to send an overboost alarm to the mobile computing device via the wireless communication module when the manifold pressure is above an overboost threshold pressure.

11. The wireless turbo boost controller of claim 6 wherein the wireless turbo boost controller is configured to send the RPM signal to the mobile computing device via the wireless communication module.

12. The wireless turbo boost controller of claim 11 wherein the setpoint duty cycle can be adjusted by the user based on the RPM signal and employing the mobile computing device.

13. The wireless turbo boost controller of claim 1 wherein the wireless communication module is a BLUETOOTH®

communication module.

14. A computer program product for operating a wireless turbo boost controller in a turbo system of a vehicle, wherein the computer program product includes code stored on a non-transitory computer-readable medium of a mobile computing device that directs a processor of the mobile computing device to perform a method to direct operation of a wireless turbo boost controller, the method comprising:

providing a setpoint duty cycle; and

sending the setpoint duty cycle to the wireless turbo boost controller via a wireless communication module, wherein the wireless turbo boost controller generates a solenoid control signal from a pressure signal indicative of a manifold pressure of an engine of the vehicle, a RPM signal indicative of an RPM of the engine of the vehicle, and the setpoint duty cycle.

15. The computer program product of claim 14 wherein the method further comprises receiving the RPM signal from the wireless communication module.

16. The computer program product of claim 14 wherein the providing includes selecting the set point duty cycle from multiple options of set point duty cycles.

18. The computer program product of claim 14 further comprising receiving a selection of a sensitivity setting and sending the sensitivity selection to the wireless turbo booster controller.

19. The computer program product of claim 14 wherein the setpoint duty cycle is received during a user defined time duration.

20. A turbo boost control system for a vehicle, comprising:

a wastegate solenoid; and

a wireless turbo boost controller configured to control the wastegate solenoid, the wireless turbo boost controller including;

a wireless communication module;

an input interface configured to receive a pressure signal indicative of a manifold pressure of an engine of the vehicle and a RPM signal indicative of an RPM of the engine of the vehicle; and
