  • Patent number: 10202919
    Abstract: An engine output control device controls engine output at a time of a downshift speed change of a transmission. The engine output control device includes: engine speed detecting means for detecting an actual engine speed NeJ of a crankshaft; and engine output adjusting means capable of adjusting the engine output according to an operation of a rider. The smaller of a requested engine output PA calculated on a basis of the actual engine speed NeJ and a rider requested engine output PB adjusted by the engine output adjusting means is output as the engine output.
    Type: Grant

  • Patent number: 9114797
    Abstract: An engine control apparatus includes a first operation member and a second operation member for braking a front wheel and a rear wheel of a saddle-type vehicle, and an engine controller that automatically stops and restarts an engine mounted in the saddle-type vehicle in response to the operational state of the first operation member and the second operation member. When a prescribed amount of time has passed while the first operation member and the second operation member are both in an operated state, the engine controller automatically stops the engine; when the first operation member and the second operation member are both released, the engine controller restarts the engine; and when either one of the first operation member and the second operation member is operated after the engine has automatically been stopped, the engine controller allows the engine to continue in the automatically stopped state.
