  • Method of heating catalyst through system cooperation and vehicle
    Patent number: 12253037
    Abstract: A method of heating catalyst through system cooperation implemented by a vehicle may enable the start of an engine of a part load among engine operation modes to heat a catalyst even in a cold quick acceleration situation with a lock-up CH control by locking up an engine clutch through system cooperation implemented by mutually exchanging information between controllers of an engine management system (EMS) and a hybrid control unit (HCU) by applying a lock-up CH control logic which retards a lock-up CH ignition angle compared to an idle CH control logic of the conventional method, thereby improving the regulation responsiveness, fuel efficiency, and merchantability relatively compared to the idle CH even while having the advantages of the idle CH in which quick lambda feedback control for an engine is possible.

  • Wireless Charging Control and Coordination
    Publication number: 20250055325
    Abstract: A first wireless power system having a first transmit device and a first receive device is operable in close proximity to a second wireless power system having a second transmit device and a second receive device. Each transmit device includes a respective coil driven by an inverter and measurement circuitry that controls the power transmitting devices to promote coexistence of the nearby systems.
