    Abstract: In a slip control device for an electric vehicle, a slip control section is provided which is configured to perform, in a control repetition cycle, a series of slip control of determining whether or not a slip state has occurred, on the basis of the number of rotations of a drive wheel and the number of rotations of a driven wheel observed by respective rotation number observation sections and, and decreasing a torque command value to a motor if the slip state has occurred. A vehicle speed detection section configured to detect a vehicle speed and a control repetition cycle change section configured to lengthen the control repetition cycle of the slip control section when the vehicle speed detected by the vehicle speed detection section is in a predetermined low-speed range, are provided.

    Abstract: A motor bicycle control system is provided for controlling a motor for assisting rotation of a bicycle wheel. The bicycle motor control system includes a motor communication part and a first mode switching part. The motor communication part performs power line communication with an electrical bicycle component and that changes a motor operation mode of the motor. The first mode switching part is operated either by electrical power supplied via a power line through which the motor communication part performs power line communication, or by electrical power obtained from a generator. The first mode switching part switches the motor operation mode from a motor driving mode in which the motor assist in rotating the bicycle wheel to a motor power generating mode in which the motor outputs electrical power that has been generated using rotation of the bicycle wheel according to a state of communication with the electrical component.

    Abstract: In one aspect, a system for torsional damping of electric traction drives comprises dual Kalman filters to correct for oscillations based on measured traction motor speed and commanded traction motor torque. A first Kalman filter can perform a state space estimate of the shaft torque providing negative feedback to the final torque command in order to eliminate resonant components from the commanded torque and quickly damp external disturbances. A second Kalman filter provides a state space estimation of the load torque or, equivalently, load acceleration. This second Kalman filter can ignore commanded torque and can provide a damping feedback when the wheel speed deviates from the vehicle speed.

    Abstract: The movement speed v of a moving body having driving wheels driven by a motor, the rotational speed ω of the drive wheels of the moving body, and the actual torque value Tm generated by the motor are acquired. Subsequently, a limiting part calculates an estimated slip ratio λ and an estimated driving torque Td on the basis of the movement speed v, the rotational speed ω and the actual torque value Tm. Next, the limiting part, after calculating a limit value L on the basis of the estimated slip ratio λ and estimated driving torque Td, uses the limit value L to calculate a limited torque value TL. Further, with an adhesive model as the reference model, a feedback part calculates a feedback torque value Tf on the basis of the rotational speed ω and the actual torque value Tm.
