==HYBRID ELECTRIC VEHICLE AND METHOD OF CONTROLLING ENGINE SPEED FOR THE SAME - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18101442 titled 'HYBRID ELECTRIC VEHICLE AND METHOD OF CONTROLLING ENGINE SPEED FOR THE SAME

==Simplified Explanation==

The patent application describes a method for controlling the engine speed of a hybrid electric vehicle by compensating the output torque of the first motor based on a compensation value determined from the difference in rotational speed between the engine and the second motor.

* The method involves determining a compensation value based on the rotational speed difference between the engine and the second motor when a control entry causes a rotational speed mismatch.
* The output torque of the first motor is then adjusted based on the compensation value to ensure smooth operation of the hybrid electric vehicle.

== Potential Applications ==
The technology described in the patent application could be applied in the automotive industry for the development of more efficient and optimized hybrid electric vehicles.

== Problems Solved ==
This technology helps address issues related to engine speed control and torque output in hybrid electric vehicles, ensuring better performance and efficiency.

== Benefits ==
The benefits of this technology include improved overall performance, increased fuel efficiency, and reduced emissions in hybrid electric vehicles.

== Potential Commercial Applications ==
The technology could be utilized by automotive manufacturers to enhance the performance and efficiency of their hybrid electric vehicle models, attracting environmentally conscious consumers.

== Possible Prior Art ==
One possible prior art could be existing methods for controlling engine speed and torque output in hybrid electric vehicles, which may not be as efficient or optimized as the method described in the patent application.

=== What is the specific mechanism used to determine the compensation value in the method described in the patent application? ===
The specific mechanism used to determine the compensation value is based on the difference in rotational speed between the engine and the second motor when a control entry causes a rotational speed mismatch.

=== How does compensating the output torque of the first motor based on the compensation value contribute to the overall performance of the hybrid electric vehicle? ===
Compensating the output torque of the first motor based on the compensation value helps ensure smooth operation and optimal performance of the hybrid electric vehicle by addressing any rotational speed mismatches between the engine and the second motor.


==Original Abstract Submitted==

Disclosed are a hybrid electric vehicle and a method for controlling an engine speed of a hybrid electric vehicle. In particular, the method includes: determining, when an engine on one end and a first motor are directly connected and while driving in a state where an engine clutch is connected and a second motor is connected to the other end, a compensation value based on the difference in the rotational speed of the engine and the second motor when a control entry is caused, which induces the rotational speed mismatch of the engine and the second motor; and compensating an output torque of the first motor based on the compensation value.
