TEMPORARY RENTAL OF ENGINE RECALIBRATION
First Claim
Patent Images
1. A method for enabling and causing an internal combustion engine of a motor vehicle to be recalibrated, for a limited duration of use, from a first calibration which sets a first value of a performance parameter for the engine, to a second calibration which sets a second value of the performance parameter different from the first value, the method comprising:
- a manufacturer of the engine specifying conditions which a user of a motor vehicle having an internal combustion engine manufactured by the manufacturer must accept as a prerequisite to fulfillment of a request by the user for recalibration of the engine, the conditions including a limited duration for which use of the second calibration is allowed;
the user requesting, from a source having the manufacturer'"'"'s authority to enable and cause the engine be recalibrated pursuant to the conditions, that the engine be recalibrated; and
upon being informed of the user'"'"'s acceptance of the conditions, the source initiating actions of wirelessly transmitting data for the second calibration to a wireless receiver in the motor vehicle, causing the data for the second calibration to be installed in a control system of the engine and to become available for use by the control system at a beginning of the limited duration of use, and to become unavailable for use by the control system at an end of the limited duration of use.

11. A system for enabling an internal combustion engine of a motor vehicle to be recalibrated, for a limited duration of use, from a first calibration which sets a first value of a performance parameter for the engine, to a second calibration which sets a second value of the performance parameter different from the first value, the system comprising:
-
a data processor which operates under authority of a manufacturer of internal combustion engines and comprises a data base which includes;
1) data about various internal combustion engines manufactured by the manufacturer and used in various motor vehicles, the data base including data for recalibrating an engine in a selected vehicle from a first calibration which currently sets a first value of a performance parameter for the engine, to a second calibration which sets a second value of the performance parameter different from the first value, and
2) data which defines specific conditions which a user of a particular motor vehicle having an internal combustion engine manufactured by the manufacturer must accept as a prerequisite to the data processing system'"'"'s fulfillment of a request by the user to recalibrate the engine of the particular motor vehicle, the conditions including a limited duration for which use of the second calibration is allowed;a user interface via which the user can access the data processor to input certain information about the user'"'"'s motor vehicle and engine for processing in accordance with an algorithm which discloses suitability of the engine for recalibration and which specifies conditions which the user must accept as a prerequisite to fulfillment of a request by the user for recalibration of the engine, and via which the user communicates to the data processor the user'"'"'s acceptance of the conditions to cause the data processor to initiate recalibration of the engine of the particular motor vehicle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
