  "textContent": "The accuracy in controlling the heating temperature of a glow plug and the reliability of the control operation are improved. An electronic control unit 101 is configured such that a standard applied voltage for glow plugs 50-1 to 50-n is set according to the engine speed and the load conditions of the engine. In addition, a correction coefficient set in advance according to the temperature classification of the mounted glow plugs 50-1 to 50-n is readably stored in the electronic control unit 101 as a correction coefficient map. By multiplying the standard applied voltage by a correction coefficient K read from the correction coefficient map and applying a voltage of the multiplication result to the glow plugs 50-1 to 50-n as a driving voltage through the power circuit 102 to perform driving control, stable and reliable heating temperature control can be realized regardless of variations in the heating temperature characteristics.",
