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

Publication number: 20230219558Abstract: A driving force control system for a vehicle that eliminates backlash in torque transmission paths when decelerating or stopping the vehicle. In the vehicle, a differential unit reverses a torque delivered from a motor to a second output shaft. A controller generates a drive torque by an engine and a control torque by the motor when stopping or decelerating the vehicle. Consequently, a difference between torque delivered from the engine to a first output shaft and torque delivered from the motor to the first output shaft is increased to a first predetermined torque or greater, and torque delivered from the motor to the second output shaft is increased to a second predetermined torque or greater.Type: ApplicationFiled: November 2, 2022Publication date: July 13, 2023Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Yu INASE, Akira IJICHI, Yoshio ITOU, Taichi KOBAYASHI, Kunihiko USUI
