ENGINE CRUISE CONTROL WITH VARIABLE POWER LIMITS
|
| Abstract: |
A control for and method of operating a vehicle engine (12) equipped with a cruise control (44) includes apparatus for and the steps of providing a memory (86) having stored therein first and second sets of data which control the position of a fuel rack (20) as a function of engine speed, determining when the cruise control (44) is engaged, retrieving the first set of data from the memory (86) when the cruise control (44) is engaged, retrieving the second set of data from the memory (86) when the cruise control (44) is not engaged and using the retrieved set of data to control the rate of fuel delivery to the engine (12) whereby extra power is available when the cruise control (44) is engaged to minimize downshifting. Also, fuel economy is improved and the set cruise control speed is better maintained. |
