摘要:
Discontinuous torque ratio shifts by a transmission can result in complex transient exhaust conditions that can adversely affect exhaust air-fuel ratio control, which can result in ineffective regeneration. In extreme cases, the result can be irreversible damage to exhaust system components. The inventors' concept is to alter either regeneration scheduling or shift scheduling to avoid shifting while regenerating.
摘要:
A method for determining a release bearing touch point in a clutch is described. A cross shaft of the clutch is positioned in a pre-determined state. A quantity of torque is applied to the cross shaft using an actuator and a velocity change is determined in the cross shaft. An angular position of the cross shaft is recorded when the velocity change happens as the new release bearing touch point.
