Abstract

Disclosed herein are techniques for implementing vehicle ECU reprogramming, so the ECU programming, which plays a large role in vehicle performance characteristics, is tailored to current operational requirements, which may be different than the operational characteristics selected by the manufacturer when initially programming the vehicle ECU (or ECUs) with specific instruction sets, such as fuel maps. In one embodiment, a controller monitors the current operational characteristics of the vehicle, determines the current ECU programming, and determines if a different programming set would better suited to the current operating conditions. In the event that the current programming set should be replaced, the controller implements the ECU reprogramming. In a related embodiment, users are enabled to specify the ECU programming to change, such as changing speed limiter settings.

Claims

(a) enabling a driver of the vehicle to communicate with a remote representative tasked with approving such ECU speed programming changes;

(b) conveying from the remote representative to the vehicle approval to implement the ECU speed programming for a different maximum vehicle speed; and

(c) in response to receiving approval at the vehicle, automatically reprogramming the ECU in the vehicle using new ECU speed programming to implement the different maximum vehicle speed setting.

2. The method of claim 1, wherein the remote representative is a third party performing the approval for a fee.

3. The method of claim 1, wherein the step of reprogramming the ECU in the vehicle using new ECU speed programming to implement the different maximum vehicle speed setting comprises the step of reprogramming the ECU while the vehicle is operational.

4. The method of claim 1, wherein the step of reprogramming the ECU in the vehicle using new ECU speed programming to implement the different maximum vehicle speed setting comprises the step of enabling reprogramming of the ECU only while the vehicle is stationary.

5. The method of claim 1, wherein the step of reprogramming the ECU in the vehicle using new ECU speed programming to implement the different maximum vehicle speed setting comprises the step of enabling reprogramming of the ECU only while the vehicle is powered down.

6. The method of claim 1, wherein the step of reprogramming the ECU in the vehicle using new ECU speed programming to implement the different maximum vehicle speed setting comprises the step of enabling reprogramming of the ECU only while the vehicle is in park.

7. A non-transitory memory medium having machine instructions stored thereon for carrying out step (c) of claim 1.

8. The non-transitory memory medium of claim 7, having machine instructions stored thereon for carrying out the step of claim 3.

9. The non-transitory memory medium of claim 7, having machine instructions stored thereon for carrying out the step of claim 6.

10. A vehicle including a reprogrammable ECU responsible for setting maximum vehicle speed in a vehicle, vehicle comprising:

(a) the reprogrammable ECU responsible for setting maximum vehicle speed in a vehicle, the reprogrammable ECU implementing the functions of;

(i) determining if an approval for reprogramming has been received, and if so; and

(ii) automatically reprogramming the reprogrammable ECU with an approved new maximum speed setting as defined in the approval received at the vehicle.

11. The vehicle of claim 10, further comprising:

(a) a user interface enabling a driver to request a change in the maximum vehicle speed programming; and

(b) a wireless data link for conveying the driver request to a remote representative tasked with approving such ECU speed programming changes, and for receiving any approval for the ECU speed programming change.

12. The vehicle of claim 10, further comprising:

(a) a position sensing component for determining a current location of the vehicle;

(b) a wireless data link for conveying a request to a remote representative tasked with approving ECU speed programming changes, and for receiving any approval for the ECU speed programming change; and

(c) a controller that automatically analyzes currently vehicle position and current reprogrammable ECU maximum vehicle speed settings, the controller automatically using the wireless data link to send the request to the remote representative tasked with approving ECU speed programming changes if that analysis indicates that the current vehicle position corresponds to a changed maximum vehicle speed setting.

13. The vehicle of claim 12, wherein the position sensing component, the wireless data link, and the controller that automatically analyzes currently vehicle position and current reprogrammable ECU maximum vehicle speed settings are incorporated into an integrated telematics device logically coupled to the reprogrammable ECU.

14. The vehicle of claim 10, further comprising:

(a) a position sensing component for determining a current location of the vehicle;

(b) a controller that automatically analyzes currently vehicle position and current reprogrammable ECU maximum vehicle speed settings, the controller automatically generating the approval for reprogramming if that analysis indicates that the current vehicle position corresponds to a changed maximum vehicle speed setting.
