Publication number: 20240083259Abstract: An electric vehicle including a motor as a driving source includes: an accelerator; a pseudo shifter mimicking a gear changing operation; a pseudo clutch mimicking a clutch operation; a detector detecting an operation mode performed on each of the accelerator, pseudo shifter, and pseudo clutch by a driver, and a rotation speed of a driving wheel; a reaction force generator generating a reaction force in the pseudo shifter in response to a driver operation performed thereon; and a controller determining the reaction force. The controller includes a processor and a memory coupled thereto. The processor calculates a virtual differential rotation speed that is based on a virtual engine rotation speed, mimicking an engine rotation speed when the driving source is assumed as being an engine, and the rotation speed based on a detection result of the detector, and determines the reaction force based on the virtual differential rotation speed.Type: ApplicationFiled: September 1, 2023Publication date: March 14, 2024Applicant: SUBARU CORPORATIONInventors: Naonori IKEZAWA, Takahiro YAMAMOTO, Kiyofumi SATO, Hironao SATO, Kyohei YAMAMOTO, Hideto FUKUDA
