Patent number: 11993250Abstract: A drive force control system for a vehicle configured to accurately imitate a change in a drive force in a model vehicle. A drive torque simulator computes a virtual drive torque supposed to be delivered to drive wheels of the model vehicle in response to a manual operation to manipulate the vehicle, based on torque changing factors of a powertrain of the model vehicle. An actual torque calculator computes a target torque of a motor that is practically delivered to the drive wheels in the vehicle based on the virtual drive torque computed by the drive torque simulator, taking account of torque changing factors of the powertrain of the vehicle.Type: GrantFiled: July 9, 2021Date of Patent: May 28, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tatsuya Imamura, Yoichiro Isami, Yoshio Itou, Hiroyuki Amano, Akiko Nishimine, Hiroaki Ebuchi, Hiroaki Kodera
