OPTIMIZED RECUPERATION STRATEGY FOR A HYBRID VEHICLE WITH ELECTRICALLY HEATABLE CATALYTIC CONVERTER

摘要

The invention relates to a control system and a method for reducing the cooling of a catalytic converter, in particular for a hybrid vehicle. The control system (100) has an internal combustion engine (310) and an electric machine (320). Additionally, the control system (100) has a catalytic converter (200) and at least one actuator (270) which is arranged in a gas path (210). The control system (100) also has a controller (150) which is designed to determine a target braking power in a drag mode of the internal combustion engine (310), operate the electric machine (320) in a generator mode at the target braking power when the target braking power is less than a maximum recuperation power of the electric machine (320) in the generator mode, and increase a mass flow flowing through the gas path (210) by means of the at least one actuator (270).
