摘要： To improve the comfortability in riding by discriminating sudden acceleration upon startup before connection of a centrifugal clutch and limiting the engine output power. A supervision starting condition discrimination section discriminates whether or not an engine satisfies a supervision starting condition for starting discrimination of satisfaction of a starting control condition. The supervision starting condition is discriminated based on a vehicle speed, a throttle opening and an engine speed. Particularly, a condition at least of the engine speed from among the parameters such as the vehicle speed is set to a value lower than a speed at which a centrifugal clutch is connected. If the supervision starting condition discrimination section discriminates that the condition is satisfied, then a startup control condition discrimination section discriminates whether or not the vehicle is in a sudden acceleration state based on whether or not the throttle opening has a magnitude (for example, 50%) corresponding to a sudden opening of the throttle. If sudden opening of the throttle is detected, then an ignition retard section issues an instruction to an ignition timing control section to retard the ignition timing in order to limit the output power.

摘要： An operational state sensor for controlling certain operations of a work machine such as a skid steer loader based upon the fulfillment of certain operator conditions, the operational state sensor including a first switch coupled to an operator restraint mechanism and actuatable between a first mode of operation corresponding to the condition when the operator restraint mechanism is in a non-restraining condition and a second mode of operation corresponding to the condition when the operator restraint mechanism is in a restraining condition, a second switch coupled to the operator seat and actuatable between a first mode of operation corresponding to the condition when an operator is not present in the seat and a second mode of operation corresponding to the condition when an operator is present in the seat, and an electronic controller coupled to the first and second switches for receiving signals therefrom, the controller being operable to receive a first signal indicative of when the first switch is either in or out of its first mode of operation and a second signal indicative of when the first and second switches are either concurrently in their second modes of operation or at least one of such switches is out of its second mode of operation, the controller being further operable to control the certain operations of the work machine based upon said first and second signals.
