Abstract: 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.

Abstract: An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. The autonomous electronic bicycle can operate autonomously, traveling to a chosen destination based on sensor information. In addition, the autonomous electronic bicycle can be ridden by a rider as a traditional bicycle. While being ridden manually, the autonomous electronic bicycle can determine a set of safety constraints, such as maximum speed or a maximum incline, to place on the autonomous electronic bicycle while being ridden by the rider based on determined rider characteristics about the rider.

Abstract: An autonomous electronic bicycle comprises a frame, a wheel that can be powered by a first electronic motor, and a pedal assembly connected to a pedal motor. The pedal assembly is not mechanically connected to the wheel, but the autonomous electronic bicycle simulates a mechanical connection by powering the rear wheel proportional to the user's pedaling force. The autonomous electronic bicycle uses a virtual gear ratio based on the cadence of the rider, the current incline of the bicycle, and the current speed of the bicycle. The virtual gear ratio can be a ratio between a torque of the set of pedals and a torque of the wheel.

Abstract: An autonomous electronic bicycle comprises a frame, a front wheel that can be powered by a first electronic motor, a rear wheel that can be powered by a second electronic motor, and handlebars that can steer the front wheel which can be controlled by a third electronic motor. Similarly, the autonomous electronic bicycle can comprise a set of sensors used for balance. The autonomous electronic bicycle can use the balance sensors to determine a current state of the autonomous electronic bicycle and drive the electronic motors to balance the autonomous electronic bicycle and achieve a target pose of the autonomous electronic bicycle. A neural network can be trained to determine one or more motor outputs of the autonomous electronic bicycle based on the target pose and the current state.
