Patent number: 11926310Abstract: Controlling a speed limit includes determining a virtual vehicle speed as being a lower one of a vehicle speed and a target limit speed, determining a virtual APS value as being a larger one of a first APS value and a second APS value, transitioning to a second mode at a point in time at which an actual APS value and the second APS value become different, when it is expected to transition to the second mode, among a first mode for sustaining a SOC of a battery at the target limit speed and the second mode for depleting the SOC, and determining a transmission gear position by applying the determined virtual vehicle speed and the determined virtual APS value to one of a first shifting pattern and a second shifting pattern.Type: GrantFiled: September 28, 2020Date of Patent: March 12, 2024Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Hui Un Son, Sang Joon Kim, Kyu Hwan Jo, Sung Bae Jeon, Sung Hoon Yu, Joo Young Kim, Jin Kyeom Cho

Publication number: 20240067079Abstract: A brake lamp control method of a vehicle is provided. The method includes determining whether a deceleration of the vehicle based on regenerative brake through the electric motor is present in a hysteresis period between an off threshold as a reference for turning off a brake lamp and an on threshold as a reference for turning on the brake lamp. When the deceleration of the vehicle is present in the hysteresis period, the method includes determining a state of the brake lamp before the deceleration of the vehicle enters the hysteresis period. In response to determining that the brake lamp is turned on or off for a reason except for the regenerative brake before the deceleration of the vehicle enters the hysteresis period, a request for turning on the brake lamp is set or reset based on the regenerative brake in response to the determined state of the brake lamp.Type: ApplicationFiled: November 2, 2023Publication date: February 29, 2024Inventors: Hui Un Son, Sang Joon Kim, Kyu Hwan Jo, Sung Bae Jeon, Sung Hoon Yu, Joo Young Kim, Jin Kyeom Cho

Patent number: 11912168Abstract: An apparatus and method control regenerative braking torque of an electric vehicle on which an anti-lock brake system (ABS) is mounted. The apparatus and method can compensate the regenerative braking torque of the driving motor based on the behavior model of the electric vehicle, such that the ABS is prevented from entering an operating range to the maximum limit to maximize the energy recovery rate through regenerative braking. The apparatus includes a disturbance extractor that extracts a disturbance in a specific frequency band from a difference between a behavior model and an actual behavior of the electric vehicle. The apparatus includes a torque compensator that compensates for the regenerative braking torque based on the disturbance extracted by the disturbance extractor.Type: GrantFiled: August 14, 2020Date of Patent: February 27, 2024Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Sang Joon Kim, Hui Un Son, Sung Hoon Yu, Joo Young Kim, Kyu Hwan Jo

Patent number: 10752141Abstract: A bi-directional blower includes a blower body for guiding for air to flow along an entire circumference scroll shape of an inner space of the blower body. The blower body divides the inner space into an upward space and a downward space to guide air flow. The blower body comprises: an upper discharge case discharging the air flow along the entire circumference scroll shape toward the upward space through an upper discharge port; and a lower discharge case discharging the air flow along the entire circumference scroll shape toward the downward space through a lower discharge port.Type: GrantFiled: October 24, 2018Date of Patent: August 25, 2020Assignees: Hyundai Motor Company, Kia Motors Corporation, Kbautotech Co., Ltd.Inventors: Mu-Young Kim, Sang-Ho Kim, Chan-Ho Jung, Jong-Moon Yoo, Joo-Hwan Son, Young-Bok Sung, Tae-Hyung Kim, Min-Hyuk Kwak, Seon Chae Na, Hee-Dong Kong

Patent number: 10336223Abstract: A ventilation seat for a vehicle is provided. The ventilation seat is configured such that a through channel to directly discharge air is formed in a seat pad so that air supplied from an air supply unit is discharged over the seat pad through the through channel, whereby the through channel or the like can be prevented from becoming narrow or being blocked due to the weight of an occupant, resulting in increased or maximize air discharge rate.Type: GrantFiled: December 5, 2016Date of Patent: July 2, 2019Assignee: HYUNDAI MOTOR COMPANYInventors: Mu Young Kim, Sang Ho Kim, Chan Ho Jung, Jong Moon Yoo, Bong Ku Kim, Seon Chae Na, Soo Hyun Moon, Joo Hwan Son, Jun Yeol Heo, Young Bok Sung, Tae Hyung Kim
