Patent number: 11945276Abstract: The present disclosure discloses a preview vehicle height control system and a method of controlling the same. The system includes a monitoring device configured to detect the road surface condition of a driving path of a vehicle, an active suspension configured to adjust a vehicle height, a memory configured to store a plurality of data maps distinguished based on a type of bump, each data map having a vehicle dynamic characteristic as an input and a tuning factor as an output, and a controller configured to derive the tuning factor based on a data map, among the plurality of data maps of the memory, corresponding to the bump detected by the monitoring device, derive a target vehicle height in a form of a Gaussian distribution by substituting the tuning factor, and control the active suspension to follow the derived target vehicle height.Type: GrantFiled: August 19, 2022Date of Patent: April 2, 2024Assignees: HYUNDAI MOTOR COMPANY, KIA CORPORATION, FOUNDATION FOR RESEARCH AND BUSINESS SEOUL NATIONAL UNIVERSITY OF SCIENCE AND TECHNOLOGYInventors: Youngil Sohn, Min Jun Kim, Sang Woo Hwang, Sehyun Chang, Jun Ho Seong, Yong Hwan Jeong, Seong Jin Yim

Patent number: 8467835Abstract: A mobile terminal and controlling method thereof are disclosed. The mobile terminal includes a solar cell module and a selective transmitting member for selectively transmitting light, thereby supplying the light to the solar cell module selectively. Accordingly, since a light-transmitting display and a solar cell module are stacked on each other, the present invention enables a user to appreciate information displayed on the light-transmitting display while enabling the solar cell module to charge a battery. Moreover, since the light having passed through a light-transmitting display can be reflected by a selective transmission member provided between the light-transmitting display and a solar cell module, the present invention is able to enhance readability of information displayed on the light-transmitting display.Type: GrantFiled: April 29, 2010Date of Patent: June 18, 2013Assignee: LG Electronics Inc.Inventors: Yun Sung Lee, Gi Hoon Tho, Chang-Bai Won, Yong Jin Hwang

Patent number: 8456847Abstract: A mobile terminal includes: a display unit that displays information; and a frame that fixedly surrounds the display unit and is fixed to a terminal case, wherein the frame includes at least one supplementary module mounting unit allowing a supplementary module that performs a different function from that of the display unit to be integrally mounted thereon. A supplementary module different from the display unit is integrally mounted on a frame constituting a display assembly, so handling and assembling can be facilitated and production cost can be reduced.Type: GrantFiled: June 24, 2009Date of Patent: June 4, 2013Assignee: LG Electronics Inc.Inventors: Yong-Jin Hwang, Min-Soo Kim, Won-Seok Joo

Patent number: 8378796Abstract: A portable terminal and method of providing tactile sensation responsive to user touching at the portable terminal is provided. The portable terminal includes a housing disposed beneath a touch screen display, such that the housing is configured to impact the touch screen display in response to a user input impressed by touch on at least a portion of the touch screen display, the housing including at least one magnetic device configured to collide with the housing. The portable terminal further including a magnetic actuator disposed relative to the at least one magnetic device, such that the magnetic actuator controls a first magnetism that displaces the least one magnetic device having a second magnetism thereby creating the impact between the at least one magnetic device and the housing.Type: GrantFiled: June 11, 2009Date of Patent: February 19, 2013Assignee: LG Electronics Inc.Inventors: Yong-Jin Hwang, Won-Seok Joo, Young-Min Lee
