A method for a vehicle's own diagnosis of a cold start - emission reduction control strategy

摘要

A diagnosis - a cold start - emission control system for an internal combustion engine comprises a control module with a module for a calculated motor output energy, a motor output energy balance module and a diagnosis - system evaluation module. The module for a calculated motor output energy is connected with the motr output energy balance module and is configured on the basis of a motor operation torque of a motor output energy flow in the operation to determine. The motor output energy balance module is connected to the diagnosis - system evaluation module and is configured on the basis of the determined engine output energy flux and of an expected motor output energy flux a motor output energy remainder to determine. The diagnosis - system evaluation module is designed, in order to determine whether the determined engine output energy radical a is sufficient vorbestimmenten value, which indicates a correct cold start - emission control.
