  • Patent number: 11958353
    Abstract: A controllable differential system for a vehicle includes a differential that may be disengaged or engaged, and may further be locked when engaged. A differential lock switch has three positions for sending commands to an actuator for disengaging or engaging the differential and for sending commands to a controller for unlocking and locking the differential. The vehicle includes a motor, a transmission continuously connected to a rear drivetrain, and the differential mounted in a front drivetrain. The vehicle may be driven in rear-wheel drive mode when the differential is disengaged or in four-wheel drive mode when the differential is engaged. The vehicle may enforce a vehicle speed limitation or an engine speed limitation when the differential is locked while a manual override control is not activated. The vehicle may implement an anti-lock braking system that may be disabled when the differential is locked.

  • Patent number: 11952081
    Abstract: A human-powered vehicle control device includes an electronic controller that controls a transmission to shift a ratio of a rotational speed of a wheel to a rotational speed of a crank axle in accordance with a control state. In a case where the controller controls the transmission to shift the ratio in accordance with an input from a shift operation device in a first control state, the controller changes the control state to a second control state. In a case where a change amount of a parameter related to a vehicle state of the human-powered vehicle becomes a predetermined amount or greater in the second control state, the controller changes the control state to the first control state. Shifting of the ratio in accordance with a shifting condition is more restricted in the second control state than the first control state.
