Solution Overview

Problem

Reactive cooling systems in vehicles experience a lag in temperature adjustments, leading to wide temperature fluctuations in heat-producing devices like engines and transmissions, resulting in inefficient operation.

Innovation Solution

A thermal management system with a variable cooling capacity, controlled by a predictive system that anticipates future heat loads and adjusts cooling capacity accordingly, preventing significant temperature changes by increasing or inhibiting cooling based on predetermined temperature thresholds.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a reactive cooling system adjusts cooling levels based on current temperature measurements, then the system responds to temperature changes, but there is always a lag between temperature change and cooling adjustment, causing wide temperature fluctuations

Engineering Contradiction:
Improvetemperature control reliabilityVSAvoidresponse time lag
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The control system performs preliminary actions by predicting future heat loads and adjusting cooling capacity before temperature deviations occur. The controller uses predicted future heat load information to proactively modify cooling system operation, eliminating the reactive lag inherent in conventional systems that only respond after temperature changes are detected.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by continuously monitoring current temperature and comparing it with predicted future temperature based on anticipated heat loads. This feedback loop enables the controller to adjust cooling capacity dynamically, ensuring temperature remains within desired ranges by anticipating and compensating for future thermal conditions.

Inventive Principle:
Principle #23Feedback

2Stability of the object's composition

If the cooling capacity is increased to compensate for temperature fluctuations, then temperature stability improves, but energy consumption increases

Engineering Contradiction:
Improvetemperature stabilityVSAvoidcooling system energy consumption
Core Design Contradiction:
Stability of the object's compositionVSUse of energy by moving object

Solution Approach 1:

By predicting future heat loads in advance, the system performs preliminary cooling adjustments only when and where needed, rather than continuously operating at high capacity. This allows the cooling system to maintain temperature stability through targeted, predictive interventions rather than sustained high-energy operation.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The controller dynamically changes cooling system parameters (such as coolant flow rate, fan speed, or compressor capacity) based on predicted future heat loads and current temperature conditions. This parameter adjustment enables the system to achieve temperature stability while optimizing energy consumption by matching cooling capacity to actual thermal demands.

Inventive Principle:
Principle #35Parameter changes

AI summary

A thermal management system and method for a vehicle includes a cooling system having a variable cooling capacity and which is connectable to a heat-producing system of the vehicle. A control system is configured to increase the cooling capacity of the cooling system to a first predetermined level in response to the at least one input indicating an increase in the future heat load of the heat-producing system when a temperature of the cooling system is at least a predetermined temperature and the cooling system is operating below the first predetermined level. The control system is also configured to inhibit increasing the cooling capacity of the cooling system to the first predetermined level in response to the at least one input indicating an increase in the future heat load of the heat-producing system when the temperature of the cooling system is less than the predetermined temperature.
