Patent number: 11968789Abstract: A display device includes a front display area (FDA), side display areas (SDAs), and a corner display area (CDA). The SDAs and the CDA are disposed outside of the FDA. The SDAs include: a first SDA disposed at a first side of the FDA; and a second SDA disposed at a second side of the FDA. The CDA is disposed at a corner of the FDA between the first SDA and the second SDA. The CDA is connected to the first SDA and the second SDA. The FDA has a flat display surface. The first SDA, the second SDA, and the CDA respectively form a bent surface.

Patent number: 11628715Abstract: A shift control method for an automated manual transmission (AMT) of a vehicle includes: when a shift operation is started, a torque of the second motor is increased so that a change in an output torque of the output shaft due to a change in a torque of the first motor is minimized while the torque of the first motor is being decreased. According to the shift control method, the increased torque of the second motor is maintained to be constant while controlling transmission release, speed synchronization, and transmission coupling. After the control over the transmission coupling is completed, the torque of the second motor is controlled so that the output torque of the output shaft follows a predetermined target torque while the torque of the first motor is controlled to be increased.Type: GrantFiled: June 4, 2021Date of Patent: April 18, 2023Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATIONInventors: Ah Ram Lee, Kwon Su Shin, Jae Joon Lee, Jong Sool Park, Jin Young Hwang
