    摘要： A control system for a hybrid vehicle is presented. The control system can include an air/fuel ratio control module that selectively commands a rich air/fuel ratio upon starting an engine based on a temperature of an electrically heated catalyst (EHC) in an exhaust system of the engine, wherein the EHC includes a hydrocarbon (HC) adsorber. The control system can include an air pump control module that selectively activates an air pump supplying air into the exhaust system upstream from the EHC based on whether the engine is on and at least one of whether the HC adsorber is full and whether the EHC is saturated with oxygen. The control system can also include an electric heater control module that selectively activates an electric heater of the EHC based on whether the engine is on and the temperature of the EHC, as well as whether the HC adsorber is full.

    摘要： A catalyst heating system includes a monitoring module, a mode selection module and an electrically heated catalyst (EHC) control module. The monitoring module monitors at least one of (i) a first active volume of a catalyst assembly in an exhaust system of an engine and (ii) a first temperature of a non-EHC of the catalyst assembly. The mode selection module is configured to select a non-EHC radiant heating mode and generate a mode signal based on the at least one of the first active catalyst volume and the first temperature. An EHC control module increases temperature of the EHC to an elevated temperature that is greater than a stabilization temperature based on the mode signal. The stabilization temperature is greater than a catalyst light off temperature.
