  • Vehicle electronic clutch control
    Patent number: 4019614
    Abstract: After gears of a vehicle have been shifted, a controller compares the instantaneous difference between engine and transmission input speeds with the speed difference memorized during the gear shift, and automatically delays clutch reengagement, while the memorized difference is varied by factors including the engine speed and the minimum of engine and transmission speeds, until the resulting two differences reach a predetermined relation. This minimizes clutch wear and jolts.
