Abstract
This paper proposes a systematic torque control for E-bikes considering various external load conditions. For assisted E-bikes, the electromagnetic torque from the permanent magnet (PM) motor can be manipulated to reduce the pedal torque generated by the cyclist. However, the overall cycling torque is affected by external loads, the motor torque should be adaptively manipulated for these riding conditions. This paper proposes a new slope sensing method, which can effectively adjust the torque output of E-bikes, thereby improving the dynamic response of E-bikes to changes in pedaling torque and acceleration. It is concluded that the wheel acceleration and the cyclist's pedaling torque are important to determine the E-bike synergetic torque performance and the cyclist's comfort. These active E-bike torque control methods are verified through the E-bike test platform.
