VEHICLE CONTROL DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18349329 titled 'VEHICLE CONTROL DEVICE
Simplified Explanation
The vehicle described in the patent application includes an internal combustion engine with a catalyst for exhaust gas purification and an automatic transmission with a parking lock mechanism. The control device performs a warm-up operation switching process, executing a first warm-up operation when the parking lock mechanism is engaged, and a second warm-up operation with larger engine rotational fluctuation when the parking lock mechanism is disengaged.
- Internal combustion engine with catalyst for exhaust gas purification
- Automatic transmission with parking lock mechanism
- Control device for warm-up operation switching process
- First warm-up operation when parking lock mechanism is engaged
- Second warm-up operation with larger engine rotational fluctuation when parking lock mechanism is disengaged
Potential Applications

Problems Solved
This technology addresses the issue of optimizing warm-up operations in vehicles with automatic transmissions. By adjusting the warm-up process based on the status of the parking lock mechanism, the system can enhance engine performance and reduce emissions during initial operation.
Benefits
The benefits of this technology include improved engine efficiency, reduced emissions, and smoother vehicle operation during warm-up periods. By tailoring the warm-up process to the specific conditions of the vehicle, overall performance can be enhanced.
Potential Commercial Applications
Potential commercial applications for this technology include automotive manufacturers looking to improve the performance and efficiency of their vehicles. This innovation could be integrated into new vehicle models to enhance customer satisfaction and meet regulatory standards.
Possible Prior Art
One possible prior art could be similar systems used in vehicles with automatic transmissions to optimize warm-up operations based on various parameters such as engine temperature and load. Research in the field of engine warm-up processes may also reveal related technologies that address similar issues.
Unanswered Questions
== How does the control device determine the optimal warm-up process for the engine? The control device likely uses sensors to monitor engine parameters such as temperature, load, and rotational speed to determine the appropriate warm-up operation.
== What are the potential long-term effects of the second warm-up operation with larger engine rotational fluctuation? The long-term effects of the second warm-up operation may include increased wear and tear on engine components, potentially affecting the overall lifespan of the vehicle. Further research and testing would be needed to assess these potential impacts.
Original Abstract Submitted
The vehicle includes an internal combustion engine provided with a catalyst for exhaust gas purification in an exhaust passage, and an automatic transmission having a parking lock mechanism. The control device executes the warm-up operation switching process for executing the first warm-up operation when the parking lock mechanism is operating, and executes the second warm-up operation in which the rotational fluctuation of the internal combustion engine becomes larger than the first warm-up operation when the parking lock mechanism is not operating.
