Publication number: 20240123834Abstract: A control device includes a switching control unit, an information acquisition unit, and a difference acquisition unit. The switching control unit performs switching control that increases braking torque of the braking device while decreasing braking torque of the rotating electrical machine, when a vehicle is decelerated. The information acquisition unit acquires information on a state of the vehicle. The difference acquisition unit acquires a braking torque difference indicating a difference between braking torque required for keeping a stopped state of the vehicle and braking torque of the braking device, when the vehicle is stopped. After the information acquisition unit detects the stopped state of the vehicle, the switching control unit corrects output torque of the rotating electrical machine based on the braking torque difference.Type: ApplicationFiled: December 15, 2023Publication date: April 18, 2024Applicant: DENSO CORPORATIONInventors: Haibo LIU, Keisuke Kawai, Akira Sakamoto, Shigeru Kamio, Tatsuya Takagi
