Abstract
An energization control apparatus for a glow plug () includes temperature maintaining energization means (), and intermediate temperature raising meansfor resuming energization of the glow plugduring operation of an engine EN after energization by the temperature maintaining energization means (). The intermediate temperature raising means () includes resistance acquisition means (); difference calculation means () for calculating a difference between the resistance of the glow plug () and a target resistance; intermediate value setting means (); and intermediate value update means () for gradually increasing an intermediate target resistance such that the intermediate target resistance finally coincides with the target resistance. The voltage applied to the glow plug () is controlled such that the resistance of the glow plug () coincides with the intermediate target resistance.
