PURPOSE: An apparatus and a method for controlling ignition signal of a CNG vehicle are provided to control ignition signal by placing a temperature compensating circuit in an ignition control module controlling ignition signal of the CNG vehicle to compensate rise time depending on fluctuation of temperature of an ignition coil. CONSTITUTION: An apparatus comprises a vehicle working state detecting unit(100) detecting state of an ignition switch varied by change of operational state of an ignition key and fluctuation of temperature of an ignition coil(410); an engine control unit(200) receiving state of the ignition switch detected and impressed by the vehicle working state detecting unit, calculating remaining time of rise current on ignition coil side when an engine is determined to be started, and outputting ignition control signal while reducing rise remaining time by one step if the calculated remaining time of the rise current on the ignition coil side is larger than a first set time; an ignition control module(300) having a temperature compensating circuit compensating resistance of the ignition coil depending on inputted temperature of the ignition coil, and outputting ignition signal following ignition control signal impressed by the engine control unit; and an ignition driving unit(400) converting ignition signal output by the ignition control module into fixed voltage and outputting the fixed voltage.
