Unanswered Questions

How does the system determine the predetermined value for reducing engine torque?

The abstract does not specify the method or criteria used to determine the predetermined value for reducing engine torque when the battery charge decreases.

What is the specific target charge amount set for the electric motor to recharge the battery to?

The abstract does not mention the specific target charge amount that the electric motor is controlled to achieve during the battery recovery process.

Original Abstract Submitted

when the remaining charge amount of the battery decreases to a predetermined value or less, the engine torque reduction control unit reduces the torque of the engine such that the operating point of the engine falls within a predetermined engine torque stable region. then, in a state in which the operating point of the engine is within the engine torque stable region, the torque of the electric motor is controlled by the charging control unit so that the actual charge amount by the electric motor becomes a preset target charge amount. this makes it possible to recover the battery from a state in which the charge amount is insufficient.
