Solution Overview
Problem
Existing vehicles face limitations in maintaining traveling state when the cooling efficiency of an internal combustion engine is reduced due to shutter abnormalities hindering cool air supply to the radiator, potentially leading to overheating and reduced vehicle performance.
Innovation Solution
A vehicle control device with an abnormality determination unit to detect cooling mechanism issues and a control unit that limits electrical power supply to the second driving source when cooling abnormalities are detected, ensuring efficient power distribution and preventing overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the shutter is opened to supply cool air to the radiator, then the cooling efficiency of the internal combustion engine is improved, but the vehicle cannot maintain traveling state for extended periods when cooling efficiency is limited
Solution Approach 1:
The control unit changes the operational parameters of the vehicle by limiting electrical power supply to the second driving source when cooling abnormality is detected. This parameter change allows the vehicle to maintain stable operation for extended periods despite reduced cooling efficiency, resolving the contradiction between temperature control and traveling duration
Solution Approach 2:
The system dynamically adjusts power distribution between driving sources based on real-time cooling status. When cooling abnormality occurs, the control unit dynamically limits power to the second driving source, enabling the vehicle to adapt to changing thermal conditions and maintain traveling capability
2Power
If electrical power is supplied to the second driving source, then vehicle performance is improved, but overheating occurs when cooling mechanism has abnormality
Solution Approach 1:
The abnormality determination unit continuously monitors the cooling mechanism status and provides feedback to the control unit. Based on this feedback, the control unit adjusts electrical power supply to the second driving source, preventing overheating while maintaining optimal vehicle performance under normal cooling conditions
Solution Approach 2:
When cooling abnormality is detected, the control unit applies partial action by limiting electrical power supply to the second driving source rather than completely shutting it down. This partial limitation prevents overheating while allowing the vehicle to continue operating in a reduced capacity
