<p><P>PROBLEM TO BE SOLVED: To provide a controller of an internal-combustion engine which prevents flickering of lamps by curbing a variation in generated voltage by a generator to reduce noises exerted on electric equipment. <P>SOLUTION: The controller of an internal-combustion engine is equipped with a generator 102 which receives motive energy from an internal-combustion engine 101 mounted on a vehicle to generate electric power, a crank shaft rotary angle detection means 103 which detects a rotary angle of a crank shaft in the internal-combustion engine, a crank reference position detection means 104 which detects a reference position of the crank shaft from output information of the crank shaft rotary angle detection means, a target voltage setting means 108 which sets a target generation voltage of the generator depending on a driving state of the vehicle, and a field current regulation means 109 which regulates an amount of a field current in the generator corresponding to the generating voltage that has been set. The amount of the field current is increased according to a crank angle in the vicinity of a TDC during an ignition stroke from a TDC to the next TDC in the internal-combustion engine, while the amount of the field current is decreased according to a crank angle in the vicinity of a middle point between the TDCs. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
