Abstract
A method for operating a clutch includes operating the clutch with increased slip during a green phase and operating the clutch with normal slip during a post-green phase. In some example embodiments, increased slip consists of slip speeds greater than 40 revolutions per minute. In an example embodiment, increased slip consists of a slip speed of approximately 50 revolutions per minute.
Claims11
A method for operating a clutch comprising:
- operating the clutch with increased slip during a green phase;
- and,
- operating the clutch with normal slip during a post-green phase.
A clutch control system for a vehicle including:
- an engageable clutch for connecting a prime mover to a transmission;
- a first sensor for measuring a rotational output speed of the prime mover;
- a second sensor for measuring a rotational input speed of the transmission;
- and,
- a processor for adjusting the clutch engagement, wherein:
- the processor is connected to the first sensor and the second sensor;
- the processor adjusts the clutch engagement based on information from the first sensor and the second sensor;
- and,
- the processor is configured to adjust the clutch to increase a clutch slip speed between the rotational output speed of the prime mover and the rotational input speed of the transmission during a green phase.
