Patent 9616755 was granted and assigned to Kawasaki on April, 2017 by the United States Patent and Trademark Office.
A regenerative brake control system of an electric motorcycle comprises an electric motor, sensors for detecting vehicle states of the electric motorcycle, and a control unit which sets target regenerative torque based on the vehicle states, when a regeneration condition is satisfied, and performs asymptotic control in such a manner that a torque command provided to the electric motor gets gradually close to the target regenerative torque with a passage of time.
