Title:
HYBRID VEHICLE
Document Type and Number:
Japanese Patent JP2021031038
Kind Code:
A
Abstract:
To suppress the heat generation of a stepped transmission when down-shifting a gear change stage of the stepped transmission accompanied by an increase of an accelerator operation amount.SOLUTION: When a requirement drive force is equal to a first upper limit drive force or smaller, a control device sets the requirement drive force as a target drive force, when the requirement drive force is larger than the first upper limit drive force, sets the target compensation power of an accumulation device on the basis of a difference between the requirement drive force and the first upper limit drive force, outputs upper limit power from an engine, sets a second upper limit drive force of a drive shaft when the accumulation device performs an accumulator-power compensation for performing charging and discharging by power based on the target compensation power, and sets a smaller one out of the requirement drive force and the second upper limit drive force as the target drive force. Also, when the control device determines a downshift of a gear change stage of a stepped transmission accompanied by an increase of an accelerator operation amount in the middle of the execution of the accumulator-power compensation, the control device limits the accumulator-power compensation.SELECTED DRAWING: Figure 6
