Publication number: 20190113137Abstract: A device synchronizes primary speed of a primary shaft receiving an electrical torque from an electric machine with a secondary speed lower than the primary speed of a secondary transmission shaft. The primary shaft and secondary shaft are decoupled. The primary shaft has a kinetic energy associated with the primary speed. The device provides electrical braking torque to the primary shaft until the primary speed is substantially equal to the secondary speed. The device also at least partially recovers, in the form of electrical energy, the kinetic energy lost by the primary shaft and transmits the electrical energy to an energy storage device.Type: ApplicationFiled: April 26, 2017Publication date: April 18, 2019Applicant: RENAULT s.a.s.Inventors: Pedro KVIESKA, Ludovic MERIENNE
