VEHICLE CONTROL DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240110528 titled 'VEHICLE CONTROL DEVICE

Simplified Explanation

The patent application describes a vehicle with an internal combustion engine equipped with a catalyst for exhaust gas purification and an automatic transmission with a parking lock mechanism. The control device of the vehicle executes warm-up operations based on the status of the parking lock mechanism.

• The control device switches to the first warm-up operation when the parking lock mechanism is engaged.
• The control device switches to the second warm-up operation when the parking lock mechanism is disengaged, causing the engine's rotational fluctuation to increase.

Potential Applications

This technology could be applied in various vehicles with internal combustion engines and automatic transmissions to optimize warm-up operations based on the parking lock mechanism's status.

Problems Solved

1. Efficient warm-up operations tailored to the vehicle's usage of the parking lock mechanism. 2. Improved exhaust gas purification during different engine operating conditions.

Benefits

1. Enhanced engine performance and longevity. 2. Reduced emissions and environmental impact. 3. Optimal warm-up processes for improved fuel efficiency.

Potential Commercial Applications

Optimized warm-up operations in vehicles for better performance and reduced environmental footprint.

Possible Prior Art

Prior art may include patents related to engine warm-up processes and automatic transmission control systems in vehicles.

How does this technology impact overall vehicle efficiency?

This technology can improve overall vehicle efficiency by optimizing warm-up processes and reducing emissions. It ensures the engine operates at its peak performance levels, leading to better fuel economy and reduced environmental impact.

What are the potential long-term effects of the increased rotational fluctuation of the engine during the second warm-up operation?

The increased rotational fluctuation during the second warm-up operation may lead to higher stress on engine components over time. It is essential to assess the long-term effects on engine durability and performance to ensure the technology's sustainability.

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.
