<P>PROBLEM TO BE SOLVED: To provide a fuel injection control system which can appropriately control a fuel injection quantity at the time of acceleration, even if a real opening of a throttle valve overshoots or undershoots relative to a target opening. <P>SOLUTION: The fuel injection control system is provided with a throttle-by-wire (TBW) system detecting an operation condition of a throttle grip 26 and controlling a throttle valve 28 by an actuator 31, and is adapted to detect an opening F of the throttle valve 28 and control an injector 29. An increased quantity correction value is determined on the basis of an output of a throttle valve opening sensor 31 and the operation condition of the throttle grip 26 when executing fuel increasing quantity correction by detecting an acceleration condition of the motorcycle 1 according to the output of the throttle valve opening sensor 31. Even if an acceleration condition of the motorcycle 1 is detected, the increased quantity correction value is brought to an attenuation condition in which the increased quantity correction value is gradually decreased, or a stop condition in which the increased quantity correction value is made to zero, if the throttle grip 26 is not moving in an opening direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
