A fuel injection control device includes a throttle opening read timing setter that sets the timing at which a throttle opening is read. The setter is triggered to detect the throttle opening used for calculation of a basic injection amount by the start of calculation timing of the basic injection amount (FICAL) if the FICAL is at the position corresponding to a toothless part of a crank pulsar rotor. The setter detects the throttle opening based on crank pulse interrupt according to a crank pulse if the FICAL is at a position other than the position corresponding to the toothless part.

Fuel injection control device for saddle-ride type vehicle

A traction controlling apparatus is configured such that if a slip of a driving wheel is detected, then a throttle valve opening is reduced to a first predetermined value. If failure is detected while the throttle valve opening is reduced to the first predetermined value, then the throttle valve opening is further reduced to a second predetermined value. If the acceleration grip is manipulated to a fully closed position while the throttle valve opening is reduced to the second predetermined value, then the control is ended and throttle control by a direct manipulation of the acceleration grip is enabled.
