PROBLEM TO BE SOLVED: To provide a control device for an on-vehicle engine capable of improving also emission of a vehicle as the vibration of the vehicle is suppressed through control of an engine loaded on the vehicle. SOLUTION: A correction logic part 103 calculates with the lapse of time a correction throttle valve opening and a correction ignition timing based on the operation state (a load, a rotation speed, and air fuel ratio etc.) of an engine, and a correction value calculated with the lapse of time is inputted to a filter logic part (low pass filter). Thereafter, a correction computing part 104 performs substraction processing (correction) on each of a throttle valve opening and an ignition timing based on each of correction values outputted from the filter logic part. A combustion control logic part 102 controls drive of an electronic valve and an ignition plug based on the corrected throttle valve opening and ignition timing. COPYRIGHT: (C)2005,JPO&NCIPI
