Abstract
A system and control module for controlling an electrically heated catalyst includes a remote start module generating a remote start signal, a catalyst control module controlling the electrically heated catalyst based on the remote start signal and an engine control module starting the engine after preheating and/or when required by the vehicle to honor a request as defined in this document.
Claims20
A method of operating a vehicle comprising:
- generating a remote start signal;
- in response to the remote start signal, initiating preheating of an electrically heated catalyst;
- and
- starting an engine independent of a state-of-charge of a battery in response to a catalyst temperature being less than a predetermined temperature when an ignition is in an off position after initiating preheating.
