Patent number: 11932118Abstract: The electric vehicle according to the present disclosure calculates motor torque using an MT vehicle model simulating an MT vehicle having a manual transmission and an internal combustion engine. In the first operation mode, an operation amount of a pseudo-clutch pedal and a shift position of a pseudo-gearshift are input to the MT vehicle model to reflect operation of the pseudo-clutch pedal and operation of the pseudo-gearshift in electric motor control. In the second operation mode where the operation of the pseudo-clutch pedal is not needed, an operation amount of a clutch pedal calculated by a driver model is input to the MT vehicle model instead of the operation amount of the pseudo-clutch pedal.Type: GrantFiled: June 16, 2021Date of Patent: March 19, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Akiko Nishimine, Yoichiro Isami, Yoshio Itou, Hiroyuki Amano, Tatsuya Imamura, Hiroaki Ebuchi, Hiroaki Kodera
