Friction Coefficient Determination to Adjust Braking for Electronic Bicycles

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.

Electric bikes (“e-bikes”) configured to achieve automatic and dynamic ride control based on a rider's desired ride objective without requiring direct physical inputs from the rider during the ride are disclosed. A rider specifies, via her mobile device or a device integrated with the e-bike, various input parameters representative of a desired ride objective. An objective-based ride control algorithm is then executed to determine—based on sensor information indicative of input variables such as pedal cadence, vehicle speed, current transmission position, electric motor power, GPS location, terrain elevation, and the like—settings for controlled variables such as transmission ratio, motor assist level, braking force, and/or suspension pressure in order to support the rider's desired ride objective, as represented by the specified input parameters. As such, a rider achieves a desired ride experience without having to directly manipulate controlled variables during the ride.
