Patent number: 10384666Abstract: Disclosed herein is a technique for improving drivability of a vehicle by controlling the driving of the vehicle by a double clutch when the clutch of a double clutch transmission (DCT) is overheated. There is provided a shift control method for a hybrid vehicle with a DCT. In particular, where it is desired to perform shifting when one of clutches of the DCT is overheated, double-clutch shifting is performed using a non-overheated clutch and an engine clutch without using the overheated clutch, thereby reducing disharmonic shifting in virtue of a small difference in gear ratio during shifting and improving shifting and driving performance.Type: GrantFiled: November 9, 2017Date of Patent: August 20, 2019Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventor: Young Min Yoon
