摘要： A first target engine speed is set in response to a command value commanded by a command unit. A second target engine speed equal to or lower than the first target engine speed is set based on the first target engine speed. When the first target engine speed is reduced, the second target engine speed is set to be constant or be decreased and a reduction range for decreasing the first target engine speed to the second target engine speed is set to be decreased. The reduction range is set at zero when the first target engine speed is equal to or lower than an engine speed at least at a maximum torque point.

摘要： A variable-input driving system includes first and second rotatable components rotating at different speeds. First and second sensors measure the rotation of the first and second components, and provide signals to an electronic controller. A drive selector has an input connected to each of the first and second components and an output connected to a driven component. The drive selector is responsive to a command signal from the electronic controller to selectively engage the first or second input with the output such that rotation of the first or second input is transmitted to the driven component based on the first and second signals.

摘要： A power source control circuit for a working machine includes an electric circuit connecting a key cylinder, controller and accessories. The electric circuit is provided with a first self-holding relay drivable directly by a relay drive signal outputted from the controller and second self-holding relays drivable in conjunction with the first relay. When a gate lock switch is switched to a lock position while an engine is running, the controller outputs an engine stop signal at a subsequent predetermined timing to stop the running of the engine, and also outputs the relay drive signal to drive the first relay and second relays such that a key-on power supply and an accessory power supply are each held in a cut-off state.
