A method of operating a vehicle under frozen diesel emission fluid conditions

摘要

A method of controlling a vehicle includes determining whether diesel emission fluid is at least partially frozen and determining whether the vehicle is currently operating in a low diesel emission fluid induction log. If the vehicle is not currently operating in the low diesel emission fluid induction protocol and the diesel emission fluid is at least partially frozen, then a temporary minimum diesel emission fluid mass may be defined to prevent entry of the vehicle into the low diesel emission fluid induction log.
