  • Patent number: 11975795
    Abstract: A leaning vehicle includes a vehicle body, a plurality of wheels, a lean mechanism, and a lean stopper mechanism. The wheels include a left front wheel and a right front wheel. The lean mechanism causes the left front wheel and the right front wheel to lean about a front-rear direction as a rotation center when the vehicle body leans about the front-rear direction as a rotation center. The lean stopper mechanism prevents a lean angle from exceeding a limit angle. in a plan view, an area bounded by lines connecting contact positions of ground and tires of the plurality of wheels is referred to as a grounding surface inner area, and a gravity center is positioned in the grounding surface inner area in a state where the lean angle reaches the limit angle.

  • Publication number: 20240132147
    Abstract: A vehicle power supply system includes a power source control device that executes a process of switching a connection state of a driving circuit to the main power source and an auxiliary power source including; a process of switching the connection state so as to transition to a backup state as a voltage decrease of the main power source occurs, and a process of switching the connection state so as to transition to a normal state as the voltage decrease of the main power source is resolved. After a voltage decrease of the main power source occurs, a turning-side control device of a steering control unit sets an output-limited state for a turning-side motor. The output-limited state is canceled upon the power source control device completing switching of the connection state so as to transition.

  • Publication number: 20230213937
    Abstract: A utility vehicle includes: a travel structure including a front wheel, a rear wheel, a steering structure mounted to the front wheel, and a drive source that drives the front wheel and/or the rear wheel; circuitry that controls the travel structure to effect autonomous travel without manned operation in a given travel area; a route setter that sets a travel route for the autonomous travel; a vehicle location detector that detects a location of the utility vehicle; and a target detector that detects a monitoring target in the travel area. In case that the monitoring target is detected at a location during the autonomous travel, the circuitry stores the location of the monitoring target as history information. The route setter sets a reference point at the location where the monitoring target was detected and sets the travel route based on the reference point.
