Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle cooling systems are often oversized for normal driving conditions, leading to excessive power consumption and increased fuel consumption due to their design focusing on extreme ambient conditions.
Innovation Solution
A method that involves selecting the most efficient combinations of hardware components and actuator positions for the vehicle cooling system based on predefined driving conditions to minimize power consumption, while ensuring the system meets durability and cooling requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cooling system is designed to meet maximum vehicle performance under extreme ambient conditions, then the cooling performance is improved, but the power consumption increases
Solution Approach 1:
The cooling system transitions from a static, fixed-component design to a dynamic, adjustable configuration. Multiple hardware components (grille shutters, cooling fans, water pumps, coolant valves) are made可调 through actuator positions that can be optimized for different driving conditions, allowing the system to adapt its power consumption characteristics to match actual cooling demands rather than always operating at maximum capacity
Solution Approach 2:
The system optimizes power consumption by changing operational parameters (actuator positions) of various cooling components. By adjusting grille shutter positions, fan speeds, pump flow rates, and coolant valve openings, the system can modify its thermal management characteristics to achieve minimum power consumption while still meeting cooling requirements for specific driving conditions
2Reliability
If the cooling system is oversized for normal driving conditions, then the cooling capacity is improved, but the fuel consumption increases
Solution Approach 1:
The system applies partial action by using only the necessary portion of the cooling system's capacity for each driving condition. Rather than always deploying the full oversized cooling capacity, actuators adjust component positions to provide exactly the cooling needed, avoiding the excessive power consumption that would result from using maximum cooling capacity during normal driving conditions
Solution Approach 2:
The cooling system becomes dynamically adjustable through multiple actuator positions on various components. This allows the oversized system to operate at different capacity levels matching actual demand, thereby reducing fuel consumption during normal driving while retaining the cooling capacity when extreme conditions require maximum performance

AI summary
A method of minimizing overall power consumption of a vehicle cooling system includes performing a hardware selection phase, performing an actuator position selection phase, and configuring operation of selected hardware components of the vehicle cooling system at a selected actuator position combination when the vehicle is operating in a predefined driving condition.
