A system for providing a movement assistance to an electric cycle is provided. The system includes circuitry communicatively coupled to an electronically-actuated driving mechanism and a sensor system of the electric cycle. The circuitry receives sensor information associated with the electric cycle through the sensor system and determines an inclination of the electric cycle with respect to an inclination-reference based on the received sensor information. The circuitry further determines occupancy information associated with a seat of the electric cycle based on the received sensor information. Based on the determined inclination and the determined occupancy information, the circuitry controls the electronically-actuated driving mechanism to drive at least one wheel of the electric cycle.

The bicycle control device includes an electronic controller that controls an operational state of a bicycle component based on at least an operational state of the bicycle electric assist unit. The bicycle component includes at least one of an electric suspension and an electric adjustable seatpost.

Various electric balance vehicles are described. In some embodiments, the vehicle has first and second housings with platforms to support a user's feet. The first and second housings can be rotatable relative to each other. The vehicle can have first and second wheel assemblies. A support member can extend within tapered portions of the first and second housings. In some embodiments, one of the first and second housings can rotate relative to the support member and the other of the housings can be rotationally fixed relative to the support member. The vehicle can balance and provide locomotion to the user. The vehicle can be light, compact, and/or have a low center of gravity.

A method of operating a vehicle is provided. The vehicle includes: an engine; a throttle operator moveable by a driver; a throttle valve regulating airflow to the engine; a continuously variable transmission (CVT) operatively connected to the engine; at least one ground engaging member including at least one of: a wheel and a track; a piston operatively connected to a driving pulley of the CVT for applying a piston force to the driving pulley when actuated and thereby changing an effective diameter of the driving pulley; and a control unit for controlling actuation of the piston and the piston force. The method includes: determining a driven pulley speed of a driven pulley of the CVT; detecting an uphill stand condition indicative of the vehicle being stopped on an uphill; responsive to the detection of the uphill stand condition, controlling the piston force based on the driven pulley speed.

A human-powered vehicle control device includes an electronic controller configured to control a transmission that changes a transmission ratio of a rotational speed of a wheel of a human-powered vehicle to a rotational speed of a crank of the human-powered vehicle. The electronic controller is configured to control the transmission to change the transmission ratio in accordance with a comparison of a parameter related to at least one of a traveling environment and a traveling state of the human-powered vehicle with a predetermined determination value. The electronic controller is configured to change the predetermined determination value in accordance with a change in the parameter during a single rotation of the crank.

A lighting system for a vehicle having a vehicle structure has a housing and a lens. A plurality of light sources are disposed within the housing. A sensor is disposed between the housing and the lens and senses a condition outside the lens.

A motorcycle includes: a front wheel brake that brakes a front wheel that is supported by a front fork; a rear wheel brake; a control unit that controls an ABS modulator connected to the front wheel brake and the rear wheel brake on the basis of front wheel speed and rear wheel speed; and a front wheel rise detection unit that detects whether the front wheel is likely to rise from a road surface, wherein when the front wheel rise detection unit detects that the front wheel is likely to rise, the control unit operates the front wheel brake through the ABS modulator.

A physical exercise apparatus includes a frame equipped with a crankset and a saddle. The saddle includes a chassis fastened to the frame, two saddle parts, and articulation members for articulating each saddle part relative to the frame around a pitch axis, a roll axis, and a yaw axis. The apparatus includes sensors for detecting a pitch movement, a roll movement, and a yaw movement of each saddle part respectively about the pitch, roll, and yaw axes, these movements resulting from pedaling made by a user. At least one calculation unit determines, from output signals of the sensors, angular amplitudes of the pitch, roll, and yaw movements. At least one screen is provided in order to display, depending on the angular amplitudes determined by the calculation unit, the position on each saddle part of a bearing point of an ischium of a user in the process of pedaling.

A slope sensitive pitch adjustor for a bicycle seat includes a rotatable seat support, a gravity sensor mounted thereto, a means for rotating the rotatable seat support, and an automated controller configured to drive the rotating means in response to an acceleration signal received from the gravity sensor. The automated controller stores data representing an initial condition of a pitch angle of the rotatable seat support with respect to horizontal and executes a control algorithm to maintain the initial condition when the bicycle is ridden over changing gradients.

An electronic bicycle includes a torque control system that controls what torque is applied to wheels of the electronic bicycle by electronic hub motors. The torque control system may determine a torque to apply to the wheels based on user input signals. The torque control system also may detect when the wheels of the electronic bicycle are slipping, and adjust the torque to minimize the time that the wheel is slipping. Additionally, the torque control system may determine a coefficient of friction between the wheels and the ground and determine a maximum torque to apply to the wheels based on the coefficient of friction. Furthermore, when braking, the torque control system may determine whether torque is applied to the wheels by passive braking or by active braking.
