CONTROLLER AND CONTROL METHOD FOR VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18450876 titled 'CONTROLLER AND CONTROL METHOD FOR VEHICLE
Simplified Explanation
The patent application describes a vehicle with an internal combustion engine and an automatic transmission that can adjust torque based on the amount of water diluted in the engine's lubricating oil.
- The process calculates the diluted water amount in the engine's lubricating oil based on the engine's operation state.
- The automatic transmission adjusts torque output based on the diluted water amount, reducing torque when water dilution is high and maintaining operation of the engine.
- Potential Applications:**
- Automotive industry for vehicles with internal combustion engines - Engine performance optimization in various driving conditions
- Problems Solved:**
- Preventing engine damage due to water contamination in lubricating oil - Improving engine efficiency and longevity by adjusting torque output accordingly
- Benefits:**
- Enhanced engine performance and reliability - Reduced maintenance costs and downtime for engine repairs - Improved fuel efficiency and overall vehicle operation
Original Abstract Submitted
A vehicle including an internal combustion engine and an automatic transmission capable of transmitting and receiving torque to and from an output shaft of the internal combustion engine is controlled. During operation of the internal combustion engine, a process that calculates a diluted water amount based on an operation state of the internal combustion engine is executed. The diluted water amount is the amount of water contained in lubricating oil in the internal combustion engine. Further, a process that controls the automatic transmission such that torque per unit period in the internal combustion engine becomes smaller when the diluted water amount is relatively large compared to when the diluted water amount is relatively small, while continuing the operation of the internal combustion engine, is executed.
