A hybrid electric vehicle includes an engine, a first motor directly connected to the engine, an engine clutch, a second motor selectively connected to the first motor through the engine clutch, a transmission directly connected to the second motor, a transmission controller configured to determine whether the transmission needs to be shifted, and a hybrid controller configured to compare a target torque reduction with intervention limits of the first and second motors when the engine clutch is in a locked-up state, to set torque reduction amounts of the engine, the first motor, and the second motor, respectively, and to output a torque command for controlling the torques of the engine, the first motor, and the second motor, respectively.

Hybrid electric vehicle and shift control method thereof

A shift control method of a hybrid electric vehicle includes: determining a speed control torque based on a result of comparing a speed of an input end of a transmission with a target speed of the input end of the transmission according to a shift signal; distributing the speed control torque to a second motor connected directly to the input end of the transmission; and distributing a residual speed control torque to a first motor connected selectively to the second motor through an engine clutch based on whether the engine clutch is locked up when the speed control torque is greater than a charging limit torque of the second motor.

A hybrid vehicle and a method of controlling the same, are configured for more efficiently distributing driving power for respective driving sources. The method of controlling a hybrid electric vehicle may include determining an engine operating point in a hybrid electric vehicle (HEV) mode, and determining first torque for a first motor and second torque for a second motor based on engine torque according to the engine operating point, required torque, and a speed of an input end of a transmission, the first motor may be directly connected to the engine, the second motor may be directly connected to the input end of the transmission, and the first motor and the second motor may be connected in the predetermined drive mode using driving power of the engine.

Disclosed are a backlash vibration reduction apparatus and method capable of sufficiently performing gear alignment even when torque is increased while a vehicle is driven within a low torque range, thereby minimizing rough vibration due to backlash. The backlash vibration reduction apparatus includes a correction determination unit configured to determine whether it is necessary to correct a torque gradient to be applied for an increase to target torque in the state in which the current torque of a vehicle is retained within a predetermined low torque range and a torque gradient correction unit configured to determine a corrected torque gradient in which a torque increase rate per hour is reduced and a torque increase time period is extended by multiplying a correction factor by a first torque gradient as a torque gradient that increases the current torque upon determining that it is necessary to correct the torque gradient.

In a hybrid electric vehicle, gear shifting delay and odd feeling when shifting gears, due to the accelerator pedal being depressed after an upshift being determined according to a release of the pedal, may be prevented. A method for controlling a transmission of the hybrid electric vehicle, includes determining a gear shifting type when a predetermined gear shifting condition is satisfied; determining an engine operation mode when the gear shifting type is power-off upshift; determining, when the engine operation mode is a predetermined mode according to an air-fuel ratio condition, a compensation value according to at least one of a motor speed, an under-charging-limit available motor torque, and an engine operation point in the predetermined mode; and applying the compensation value to an engine torque.

An apparatus and a method for controlling a driving mode of a vehicle are provided. The apparatus includes a mode converter that converts the driving mode of the vehicle based on an operation of a mode conversion input. When the driving mode is converted into a custom mode, a mode setting screen for adjusting a setting value of a driving characteristic preset is configured and the configured mode setting screen is displayed on a display of the vehicle. A tuning device then tunes a driving characteristic of the custom mode based on a setting value adjusted on the mode setting screen.

Apparatus and method for controlling driving mode of vehicle

A washing machine includes a cabinet forming an external appearance of the washing machine, a tub provided in the cabinet to accommodate wash water, a drain pump coupled to a drain hose configured to guide wash water pumped by the drain pump to outside of the cabinet, and a holder coupled to an outer surface of the cabinet to fix the drain hose to the cabinet. The holder is coupled to the outer surface of the cabinet while having both ends coupled to each other to form an accommodation hole surrounding the outer circumferential surface of the drain hose, and at least one movement preventing protrusion formed on an inner circumferential surface of the holder to prevent the drain hose from being separated from the holder protrudes toward inside of the holder to come into contact with the outer circumferential surface of the drain hose.
