Vehicle Cooling Control for Special-Mode Overheating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle management systems fail to adequately cool target in-vehicle devices during high-performance modes, leading to overheating and reduced travel performance due to fixed control parameter limits that prioritize fuel efficiency over cooling capacity.
Innovation Solution
A vehicle management system that adjusts control parameter limits to enhance cooling capacity during high-performance modes, monitors and records load amounts, and estimates device lifetimes to optimize cooling and prevent overheating.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the limit value of the control parameter of the temperature control device is set to be the same as that in the case where the special mode is not set, then the life of the temperature control device is preserved, but the target in-vehicle device cannot be sufficiently cooled and becomes excessively high in temperature
Solution Approach 1:
The limit value of the control parameter is made dynamic by switching between a first limit value (for normal mode) and a second limit value (for special mode). The management controller determines the operating mode and selectively applies the appropriate limit value, allowing the system to adapt its cooling capacity to the current operational requirements rather than using a fixed limit value.
Solution Approach 2:
The control parameter's limit value is changed based on the operating mode. When the special mode is detected, the system changes the parameter from the first limit value to the second limit value, which has a higher permissible value. This parameter change enables the temperature control device to operate at higher capacity when needed to cool the target in-vehicle device effectively.
2Temperature
If the limit value of the control parameter is increased to cool the target in-vehicle device rapidly during special mode, then the cooling capability is improved, but the life of the temperature control device may be reduced
Solution Approach 1:
The system dynamically adjusts the control parameter limit value based on the operating mode. The management controller monitors the mode selection and switches between the first limit value (lower, for normal operation) and the second limit value (higher, for special mode). This dynamic adjustment allows rapid cooling when required while maintaining normal operational limits for device longevity.
Solution Approach 2:
The system applies different control parameter limit values in different operational periods or modes. During normal operation, the first limit value is applied to preserve device life. When special mode is activated, the second limit value is applied temporarily for rapid cooling. This periodic or conditional application of different parameter values balances cooling performance with device reliability.

AI summary
The vehicle management system comprises a temperature control device configured to cool and control the temperature of a target in-vehicle device that generates heat as a vehicle travels; and a management controller that controls driving of the temperature control device, wherein the management controller is configured to change a limit threshold value of a control parameter of the temperature control device in a manner to increase a cooling capability when a special mode, in which a travel performance is prioritized over a fuel consumption, is set as compared with a case where the special mode is not set.
