METHOD OF HEATING CATALYST THROUGH SYSTEM COOPERATION AND VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240093654 titled 'METHOD OF HEATING CATALYST THROUGH SYSTEM COOPERATION AND VEHICLE
Simplified Explanation
The patent application describes a method of heating a catalyst through system cooperation implemented by a vehicle to enable the start of an engine of a part load among engine operation modes, even in a cold quick acceleration situation with a lock-up clutch control. This is achieved by exchanging information between controllers of an engine management system (EMS) and a hybrid control unit (HCU) to apply a lock-up clutch control logic that improves regulation responsiveness, fuel efficiency, and merchantability.
- Explanation of the patent/innovation:
* Heating catalyst through system cooperation in a vehicle * Enabling engine start in cold quick acceleration situations * Lock-up clutch control by exchanging information between controllers * Applying lock-up clutch control logic for improved performance
- Potential Applications
This technology can be applied in vehicles to improve engine performance and fuel efficiency, especially in cold weather conditions.
- Problems Solved
This technology solves the problem of efficiently heating a catalyst and starting the engine in cold weather situations, ensuring optimal performance.
- Benefits
The benefits of this technology include improved regulation responsiveness, fuel efficiency, and overall engine performance, leading to better merchantability.
- Potential Commercial Applications
This technology can be utilized in the automotive industry for vehicles that require efficient catalyst heating and engine start in cold weather conditions.
- Possible Prior Art
One possible prior art could be the use of traditional idle clutch control logic in vehicles, which may not be as efficient in cold weather situations compared to the innovative lock-up clutch control logic described in the patent application.
- Unanswered Questions
- How does the system cooperation between the EMS and HCU improve fuel efficiency and regulation responsiveness?
The system cooperation allows for the exchange of information between controllers, enabling the application of a lock-up clutch control logic that optimizes engine performance in various operating conditions.
- What are the specific technical details of the lock-up clutch control logic compared to the conventional idle clutch control logic?
The patent application mentions that the lock-up clutch control logic retards the lock-up clutch ignition angle compared to the idle clutch control logic. However, the exact technical specifications and parameters of this logic are not provided in the abstract.
Original Abstract Submitted
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.
