Abstract
A glow plug control method of a diesel hybrid vehicle includes: determining an operation time of a glow plug based on a coolant temperature while the vehicle runs in an electric vehicle mode with an electric motor; determining whether the inside of an engine cylinder needs to be preheated based on the coolant temperature; comparing a driver-required power with a standard start power for determining whether to start a diesel engine; determining a glow plug operation time and a standard glow operation power, when the driver-required power is under the standard start power; operating the glow plug in advance, when the standard glow operation power is less than the driver-required power; and starting the diesel engine, when the driver-required power is higher than the standard start power.
