Patent number: 11585430Abstract: A method for operating a motor vehicle that has an internal combustion engine and an automated manual transmission, connected between the engine and a drive output. The transmission includes a shifting element group with a plurality of shifting elements. The transmission further includes an oil pump and an electric machine, both of which are integrated in the transmission and coupled to an input shaft of the transmission. The oil pump delivers a flow of transmission oil for cooling the shifting element group and cooling the electric machine, and the shifting elements of the shifting element group are controlled and shifted by an actuator system that is independent of the oil pump. When the motor vehicle is at rest, the oil pump is driven by the electric machine in order to cool the electric machine while the motor vehicle is at rest.Type: GrantFiled: May 15, 2020Date of Patent: February 21, 2023Assignee: ZF FRIEDRICHSHAFEN AGInventors: Michael Sauter, Markus Eisele, Martin Dietrich, Franz Bitzer

Patent number: 11554769Abstract: A vehicle includes an engine, a first MG, a planetary gear mechanism, a battery that stores power generated by the first MG and supplies the stored power to the first MG, and an HV-ECU that controls the engine and the first MG. The engine includes a turbo. A boost line is determined on a map representing a relationship between the rotation speed of the engine and torque generated by the engine, and the turbo boosts suctioned air when torque generated by the engine, as indicated by an operating point on the map, exceeds the boost line. The HV-ECU controls the engine and the first MG so that when the allowable value Wout of power output from the battery is small, the operating point exceeds the boost line at a higher rotation speed than when the allowable value Wout is large.Type: GrantFiled: March 24, 2020Date of Patent: January 17, 2023Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Koichi Yonezawa, Satoshi Yoshizaki, Osamu Maeda, Daigo Ando, Yoshikazu Asami, Kenji Itagaki, Shunsuke Oyama, Koichiro Muta
