Patent number: 10766351Abstract: A method of controlling reverse driving of a hybrid vehicle is provided, in which a reverse gear train of a gear box of a transmission for reverse driving is omitted. When a gear stage enters a reverse stage or is changed from a drive stage to a reverse stage, an engine performs an electric energy charging function on a battery via a hybrid starter generator and a motor transmits driving power for reverse driving to travelling wheels. Accordingly, the battery is charged with electric energy and simultaneously, the motor is reversely driven based on the electric energy supplied from the battery, thereby enabling a hybrid vehicle to be more easily reversed.Type: GrantFiled: October 15, 2018Date of Patent: September 8, 2020Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Seok Young Yun, Song Il Park, Tae Young Chung

Patent number: 10479205Abstract: A plug-in vehicle is provided which prevents impossibility of driving even when a charging connector is not connected to the vehicle and a method of controlling the same. The method includes determining whether the vehicle is stopped and determining whether recognition of a connection of the charging connector to the vehicle is enabled. Additionally, the method includes determining whether a charging inlet door is open or closed, in response to determining that recognition of the connection of the charging connector to the vehicle is disenabled, and executing transition of the vehicle from a first state restricting generation of driving power to a second state permitting generation of driving power when the charging inlet door is closed.Type: GrantFiled: November 15, 2016Date of Patent: November 19, 2019Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Dae Ro Park, Sang Joon Kim, Soung Han Noh, Jin Cheol Shin, Seung Jae Yoo, Seok Young Yun

Patent number: 8761979Abstract: The present invention protects a high voltage battery in a hybrid electric vehicle. More particularly, it makes it possible to prevent a battery from being overcharged when a motor or an inverter system breaks, with the hybrid vehicle traveling. The technique for protecting a high voltage battery in a hybrid electric vehicle illustratively comprises: checking whether a motor functions properly; setting a virtual acceleration pedal value and keeping a present desired shifting map, when the motor breaks; determining a desired shifting stage according to the present desired shifting map based on the virtual acceleration pedal value; and, in certain embodiments, switching or keeping the engine control mode by comparing a value of a predetermined maximum engine speed region with the present engine speed in order to prevent high-speed rotation of the motor.Type: GrantFiled: July 18, 2011Date of Patent: June 24, 2014Assignees: Hyundai Motor Company, Kia Motors CorporationInventor: Seok Young Yun

Patent number: 8663061Abstract: A gear shifting method of a hybrid vehicle may include releasing a clutch and brake of a transmission and determining a neutral condition status, controlling torque of an engine connected to one operational element of a first planetary gear set in a neutral condition, and controlling speed of a first motor/generator connected to the other operational element of the first planetary gear set. Accordingly, a speed of the first and second motor/generator are controlled and a torque of the engine is controlled in a neutral or parking state of a shift lever such that a mode change becomes easy and the torque of the engine is continuously controlled to improve a shift quality and a driving performance and to save fuel, while the neutral or parking state is changed to a drive or reverse state or the drive or reverse state is changed to the neutral or parking state.Type: GrantFiled: July 25, 2011Date of Patent: March 4, 2014Assignees: Hyundai Motor Company, Kia Motors CorporationInventor: Seok Young Yun
