  • Patent number: 11993251
    Abstract: A method and system for controlling an engine clutch of a P2 type parallel hybrid vehicle includes steps of: determining whether or not a learning mode entry condition is satisfied, depending on whether or not a kickdown shift occurs during performance of variable hydraulic control of an engine clutch and based on the degree to which slip of the engine clutch occurs, deriving and storing a learning hydraulic value for suppressing the slip that is to occur when the kickdown shift occurs during the performance of the variable hydraulic control in such a manner that the slip does not occur, when a vehicle state satisfies a predetermined learning mode entry condition, and computing a final hydraulic pressure by adding a hydraulic compensation value to a target hydraulic pressure, when the same kickdown shift situation occurs, and controlling the engine clutch using the computed final hydraulic pressure.

  • Patent number: 11724684
    Abstract: A control apparatus for controlling a vehicle includes a driving motor configured to drive the vehicle by outputting motor torque based on a supply voltage from a battery, and an engine configured to drive the vehicle by outputting engine torque. The control apparatus may acquire driving mode data which is calculated based on traffic information from the current position to the destination of the vehicle and dimension information of the vehicle, and control the vehicle to drive to the destination according to a driving mode which is determined by applying a travelling condition of the vehicle to the acquired driving mode data, where the power distribution ratio of the motor torque to the engine torque is reflected in the driving mode data.
