Publication number: US20220019219A1
Application number: 17/490,658

Abstract:
A control unit for an autonomous functioning apparatus that has a sensor, an external image-capturing camera and an actuator, and is manipulable by a remote manipulation device. The control unit is connected to a remote communication device that is connected to a cooperative control unit for controlling a cooperative functioning apparatus. The remote manipulation device is positioned outside the autonomous functioning apparatus and the cooperative functioning apparatus. The control unit includes an external image connector for receiving external image data, a functioning control connector for outputting a functioning control signal for controlling functioning of the actuator, an external communication connector for exchanging data with the remote communication device, and a functioning control device for outputting monitor image data to the remote manipulation device, based on a signal outputted from the remote manipulation device, the cooperative control unit, or the sensor. The monitor image data is based on the external image data.

Publication number: US20210404406A1
Application number: 17/473,908

Abstract:
A straddled vehicle engine unit including an internal combustion engine and a misfire detection device. The internal combustion engine has a crankshaft, and a crank angle signal output unit that periodically outputs a crank angle signal in accordance with rotation of the crankshaft. The internal combustion engine is configured to repeat at least two kinds of strokes on a cycle of every 720-degree rotation of the crankshaft. The misfire detection device includes a crankshaft rotation speed fluctuation physical quantity acquisition unit configured to acquire a physical quantity related to an amount of fluctuation in a rotation speed of the crankshaft in one kind of stroke, out of the at least two kinds of strokes, based on the crank angle signal from the crank angle signal output unit, and a misfire determination unit configured to perform a misfire determination in response to each acquisition of the crankshaft rotation speed fluctuation physical quantity.

Publication number: US20210404913A1
Application number: 17/473,865

Abstract:
A straddled vehicle engine unit including an internal combustion engine and a misfire detection device. The misfire detection device includes a crankshaft rotation speed fluctuation physical quantity acquisition unit and a misfire determination unit. The misfire determination unit includes first to third determination units. The first determination unit determines whether or not the crankshaft rotation speed fluctuation physical quantity acquired by the crankshaft rotation speed fluctuation physical quantity acquisition unit is greater than a set physical quantity determination reference. The second determination unit determines whether or not a fluctuation pattern constituted by a physical quantity and the crankshaft rotation speed fluctuation physical quantity acquired at least before or after the physical quantity falls within a set misfire pattern range. The third determination unit determines whether a misfire determination is to be set as effective or not, based on results of determination by the first and second determination units.
