Patent number: 10605216Abstract: Method and system for starting an internal combustion engine that rotates a drive shaft providing torque to a driving wheel via a transmission unit comprising a first clutch connecting the engine to an input shaft of a gearbox connected to a torque converter. The torque converter is connected to a second clutch connected to the driving wheel through a transmission, and the input shaft is connected to an auxiliary drive source in an offset arrangement with a predetermined torque ratio between the input shaft and the auxiliary drive source. Starting the engine comprises disengaging the first clutch, disengaging the second clutch to a predetermined torque level, accelerating the input shaft and the torque converter with the auxiliary drive source to a predetermined rotational speed, and engaging the first clutch to start the engine with the energy stored in the input shaft, the torque converter, and the auxiliary drive source.Type: GrantFiled: October 6, 2017Date of Patent: March 31, 2020Assignee: Volvo Car CorporationInventors: Tobias Stalfors, Jonas Forssell, Mathias Jorgensson
