Patent number: 11601005Abstract: A hybrid electric vehicle (HEV) includes: a battery, a hybrid starter generator (HSG) starting an engine, and a controller that identifies a state of charge (SOC) of the battery upon when a reverse gear input is detected, determines whether to charge the battery by the HSG based on the identified SOC of the battery. In particular, the controller controls battery charging in a charging control mode based on a SOC level of the battery when it is determined that the HSG needs to charge the battery.Type: GrantFiled: October 15, 2020Date of Patent: March 7, 2023Assignees: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Sung Hoon Choi, Young Un Kim, Yu Hyun Sung, Jeong Min Shin, Dong Jin Nam

Patent number: 9007005Abstract: Disclosed is a system and method of controlling an inverter to reduce noise in an eco-friendly vehicle. In the method, at least one of a current motor torque and a current motor speed is monitored in real-time. It is determined whether or not the at least one of the current motor torque and the current motor speed corresponds to a noise occurrence range set to a current switching frequency. A changed switching frequency value corresponding to the at least one of the current motor torque and the current motor speed is calculated when the at least one of the current motor torque and the current motor speed corresponds to the noise occurrence range. A PWM signal is generated using the changed switching frequency value to control an inverter.Type: GrantFiled: December 14, 2012Date of Patent: April 14, 2015Assignees: Hyundai Motor Company, Kia Motors CorporationInventors: Yu Hyun Sung, Seong Yeop Lim, Jeong Min Shin
