Patent number: 11453295Abstract: A control system for a vehicle to prevent a reduction in a drive force due to increase in an internal resistance of a battery. A controller calculates a command value of an output power of the battery to be transmitted to a motor in future, and predicts an internal resistance of the battery at the point to discharge the electric power from the battery in the amount of the command value. If it is expected that the battery will not be possible to discharge the electric power in the amount of the command value, the controller reduces a load on the battery by increasing an amount of the electric power supplied to the motor from the generator before the battery can no longer discharge the electric power in the amount of the command value.Type: GrantFiled: August 26, 2020Date of Patent: September 27, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Takashi Iwata, Taiga Hagimoto, Hideto Wakabayashi
