  • Publication number: 20240083410
    Abstract: 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.

  • Publication number: 20240083412
    Abstract: Disclosed is a hybrid electric vehicle and a method of controlling an engine stop for the vehicle. The method includes: determining whether a first condition and a second condition is satisfied; applying a negative torque to the motor when the first condition and the second condition are satisfied; predicting occurrence of reverse rotation of the engine; and applying a feedback torque for satisfying the target behavior of the engine to the motor when the occurrence of the reverse rotation is predicted.

  • Publication number: 20040234071
    Abstract: A desktop phone station for synchronizing desktop phone contact data with portable contact data stored in a portable data loading device. A communications port on the phone station provides a communications interface for the portable data loading device. The desktop phone station is capable of receiving the portable contact data from the portable data loading device through the communications port. A user interface is provided on the exterior of the phone. The user interface includes control buttons, one of which is a data synchronization button. When the data synchronization button is pressed, the portable contact data received through the communications port is synchronized with desktop phone contact data stored in a memory of the desktop phone station.
