Abstract
A hybrid electric vehicle has a propulsion system including an internal combustion engine (ICE) and an electric motor each configured to operate in parallel and each configured to propel the vehicle individually. A rechargeable battery is configured to deliver power to the electric motor to enable the electric motor to propel the vehicle for a certain distance without operation of the ICE. The rechargeable battery is further configured to receive power from a household power outlet. A controller is configured to control the propulsion system to operate in either a normal emissions mode or a no-emissions mode wherein the ICE is disabled. The controller is further configured to direct the propulsion system to operate in the no-emissions mode in response to the broadcast of an external control signal.
