Abstract
A method for controlling a hybrid electric vehicle includes: connecting a first motor directly connected to an engine to a second motor directly connected to a transmission input terminal through a dual mass flywheel; determining a target angular acceleration of the first motor according to a gear shifting progress rate so that an angular acceleration of the first motor follows a target angular acceleration of the transmission input terminal when a gearshift is performed in the transmission; and controlling a torque of the first motor based on the target angular acceleration of the first motor.

A method for controlling a hybrid electric vehicle comprising:
- connecting a first motor directly connected to an engine to a second motor directly connected to a transmission input terminal through a dual mass flywheel of the hybrid electric vehicle;
- determining a target angular acceleration of the first motor based on a gear shifting progress rate so that an angular acceleration of the first motor follows the target angular acceleration of the transmission input terminal when a gearshift is performed in the transmission;
- and
- controlling, by a controller, a torque of the first motor based on the target angular acceleration of the first motor.
A non-transitory computer-readable recording medium storing instructions to be executed by a processor, the instructions causing the processor to:
- in a state where a first motor directly connected to an engine is connected to a second motor directly connected to a transmission input terminal through a dual mass flywheel of a hybrid electric vehicle,
- determine a target angular acceleration of the first motor based on a gear shifting progress rate so that an angular acceleration of the first motor follows the target angular acceleration of the transmission input terminal when a gearshift is performed in the transmission;
- and
- control a torque of the first motor based on the target angular acceleration of the first motor.
A hybrid electric vehicle comprising:
- an engine;
- a first motor directly connected to the engine;
- a second motor configured for selective connection to the first motor;
- a transmission having an input terminal directly connected to the second motor;
- and
- a controller,
- wherein in a state where the first motor and the second motor are connected through a dual mass flywheel and performing a gearshift in the transmission, the controller is configured to determine a target angular acceleration of the first motor according to a gear shifting progress rate so that an angular acceleration of the first motor follows a target angular acceleration of the transmission input terminal when the gearshift is performed in the transmission, and the controller is further configured to control a torque of the first motor based on the target angular acceleration of the first motor.
