A method of controlling an electrified vehicle includes determining whether stop control using a motor is possible in a case where a condition for entering stop assist control is satisfied, performing cooperative stop control using the motor and a hydraulic brake upon concluding that the stop control using the motor is possible, and performing independent stop control using the hydraulic brake upon concluding that the stop control using the motor is impossible.

Electrified vehicle and method of controlling same

A method includes switching a vehicle to a 4WD state by connecting a disconnector, maintaining the disconnector in the connected state for a predetermined maintenance time, determining whether a condition to be switched to a 2WD state is satisfied when the predetermined maintenance time period elapses, and disconnecting the disconnector when the condition to be switched to the 2WD state is satisfied.

Method of controlling disconnector for vehicle

Fuel injection of a hybrid electric vehicle including an engine and a transmission may be controlled by a method including, determining to release coasting of the hybrid electric vehicle based on a brake pedal operation, determining whether a fuel injection suspending condition is satisfied based on vehicle running state data, suspending fuel injection when the vehicle running state data satisfies the fuel injection suspending condition, performing an engagement control of the transmission while the fuel injection is suspended, determining whether a fuel injection suspension release condition is satisfied, determining whether the engine and the transmission are directly coupled when the fuel injection suspension release condition is satisfied, and initiating fuel injection of the engine when the engine and the transmission are directly coupled.

A vehicle control method may include determining by a controller, a state of a brake pedal wherein a controller is configured to determine during performing an SSC control mode whether a brake pedal is in an ON state; determining, by the controller, overlap of control modes wherein when it is determined in the determining by a controller, a state of a brake pedal that the brake pedal is in the ON state, the controller is configured to determine whether conditions for performing an extended ISG control mode are satisfied; and converting, by the controller, a control mode wherein when it is determined in the determining, by the controller, overlap of control modes that the conditions for performing the extended ISG control mode are satisfied, the controller terminates the SSC control mode being performed and converts the current control mode to the extended ISG control mode.

Vehicle control method

A coasting driving control method and system for a vehicle may determine virtual engine RPM for a current driving state using engine RPM, vehicle speed, and gear stage information by a controller when coasting is started with the clutch in the neutral position and outputs a downshifting instruction signal for a gear stage by the controller when the virtual engine RPM is less than a coasting engine RPM which is greater than an idling RPM by a predetermined value.

Coasting driving control method and system for vehicle

A method of controlling driving of a CVT vehicle during cornering performed by a controller, may include determining whether it is necessary to perform an auxiliary control process to enhance a re-acceleration response after entering the corner, by determining a travelling state of the vehicle; setting a target gear ratio instead of a gear ratio obtained based on a shift pattern when the determining produces an affirmative result indicating that it is necessary to perform the auxiliary control process; and performing gear shifting of a CVT to follow the target gear ratio set in the setting of the gear ratio.

Method of controlling driving of CVT vehicle during cornering

A method for controlling a gear ratio of a continuously variable transmission vehicle includes: a step of detecting a position of a shift lever by a controller; a step of checking, by the controller, a gear ratio variation based on a difference between a desired stage gear ratio and a current gear ratio in a continuously variable transmission when the shift lever is detected to be positioned in a manual range; a step of calculating, by the controller, a gear ratio correction value based on a rate of change of engine RPM when the gear ratio variation is checked as being other than zero after the step of checking the gear ratio variation; and a step of correcting, by the controller, the gear ratio variation in response to the calculated gear ratio correction value after the calculation step.

An integrated control method is provided for an engine and a transmission and the method is capable of integrally controlling the engine and the transmission, based on a control correlation between the engine and the transmission. This method determines a target engine operating point reflecting a driving state of a vehicle and a driver's intention to accelerate, in an integrated control map having an engine control area and a transmission control area. The method calculates a target shift ratio based on the target engine operating point, thus being capable of significantly saving a man-hour required to set a map as compared to a conventional control method in which an engine torque map and a shift pattern map are individually set, and improving fuel efficiency.

Integrated control method for engine and transmission

A method of controlling a pulley ratio of a continuously variable transmission vehicle, includes: sensing, by a controller, whether or not the position of a shift lever switches to a manual range, fixing, by the controller, a pulley ratio of a continuously variable transmission, when the position of the shift lever switches to the manual range, as a result of sensing, re-adjusting, by the controller, set pulley ratios of a plurality of manual shift positions based on the fixed pulley ratio of the continuously variable transmission, after the fixation, and controlling, by the controller, the continuously variable transmission at the re-adjusted pulley ratio of a target manual shift position, when manual shifting is required, after re-adjustment.
