A system and method for controlling an engine in a vehicle which allows the vehicle operator to manually request a vehicle speed in excess of the established vehicle speed limit that includes establishing a normal vehicle speed limit, establishing a passing duration period, establishing a passing override reset interval, and controlling the engine in response to operator input to provide a greater vehicle speed for a cumulative period not greater than the passing duration period at any time during the passing override reset interval. The system and method may include the capability of establishing a passing speed increment and controlling the vehicle speed during passing to limit the vehicle to a speed not exceeding the normal vehicle speed limit plus the passing speed increment.
A method for controlling an engine to allow a vehicle operator to obtain a vehicle passing speed in excess of the normal vehicle speed limit, the method of comprising:
A method for controlling an engine in a vehicle including an internal combustion engine in communication with an electronic control module to allow the operator to attain a passing speed greater than the preset vehicle speed limit, the method comprising:
In a method for controlling an engine to allow an operator to override then normal vehicle speed limit for a cumulative passing period which is reestablished at a predefined reset interval, a method of determining whether the operator has tampered with the engine control system clock to obtain an additional time period for exceeding the normal vehicle speed limit, the method including:
In a method for controlling an engine which provides the operator with a particular operating capability for a time period which is reestablished at a predefined reset interval, a method of determining whether the operator has tampered with the engine control system clock to obtain an additional time period for the particular capability, the method including:
