METHOD OF CONTROLLING AN ELECTRIC OIL PUMP OF A VEHICLE
A method of controlling an electric oil pump (EOP) of a vehicle includes: confirming a gear shift type when a gear shift of a vehicle is started; compensating for the number of revolutions of the EOP according to the confirmed gear shift type; confirming whether a measured line pressure converges on a command line pressure while the compensating for the number of revolutions of the EOP according to the gear shift type is performed; and, when it is determined that the measured line pressure does not converge on the command line pressure, additionally compensating for the number of revolutions of the EOP.

Power transmission control device
An object is to reduce a delay in response. An automatic gear changing control device includes a sleeve which is moved by an actuator to perform an engagement operation, an engine which is connected to an input shaft, and a control unit which controls the movement of the sleeve by the actuator and controls the rotation of the input shaft by the engine or a motor generator. The control unit performs synchronization control of controlling the rotation of the input shaft for the engagement operation at a different gear stage after the engagement is released and starts shift control of moving the sleeve to an engagement completion position by the actuator before at least the synchronization is completed.
Clutch control method for vehicle equipped with dual clutch transmission
A clutch control method of the vehicle provided with the double clutch transmission may include determining, by the controller, whether a vehicle is travelling at the lowest shifting stage or the highest shifting stage and the pre-engagement of a proximate shifting stage is completed or not; storing a learned driveshaft clutch torque and a current clutch temperature and initiating a timer when it is determined that the learned driveshaft clutch torque is considered reliable by the controller learning the driveshaft clutch torque; determining, by the controller, a plurality of conditions including the passage of time to determine whether a touch point learning of the non-driveshaft clutch is necessary or not; and disengaging, by the controller, the proximate shifting stage of the non-driveshaft to neutral when it is determined that the touch point learning is necessary and performing the touch point learning of non-driveshaft.
