Abstract

A method to operate a vehicle having a parking brake, an odometer, and a powertrain including an engine with an electronic control unit in communication with a transmission.

Claims

1. A method to operate a vehicle having a parking brake, an odometer, and a powertrain including an engine with an electronic control unit in communication with a transmission, comprising:

determining whether said vehicle is operating in power take off mode;

determining whether said parking brake is engaged, and

disengaging an odometer accumulation function.

2. The method of claim 1 wherein said odometer accumulation includes sensing vehicle speed and logging odometer time.

3. The method of claim 1, wherein said power take off mode is determined by output of the transmission.

4. The method of claim 1, wherein when said vehicle speed is zero and said parking brake is set, the electronic control unit ceases odometer accumulation time, and stores such event in memory therein residing taxes paid based upon said odometer.

5. A method to reduce taxes paid on vehicle operation, said vehicle including a parking brake, an odometer, an engine with an electronic control unit with memory in communication with said parking brake and said odometer, and a transmission, said method comprising:

determining whether said vehicle is operating in power take off mode;

determining whether said parking brake is engaged disengaging said odometer accumulation;

logging said event in memory of electronic control unit for download.

6. The method of claim 5, wherein power take off mode is determined by output from said transmission.
