Abstract
A fuel injection control system provided with a throttle by wire (TBW) system detecting an operation condition of a throttle grip and controlling, via an actuator, a throttle valve. The control system detects the throttle valve opening and controls an injector. An increased quantity correction value is determined based upon of an output of a throttle valve opening sensor and an operation condition of the throttle grip. When an acceleration condition of a vehicle is detected according to the output of the throttle valve opening sensor, an increased quantity correction of fuel is performed. 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, when the throttle grip is not in drive in an opening direction, even though an acceleration condition is detected.
