First Claim
Patent Images
1. 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.
