Abstract
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.
