SYSTEM AND METHOD FOR DIAGNOSING LACK OF COOLANT OF VEHICLE TO WHICH INTEGRATED THERMAL MANAGEMENT VALVE IS APPLIED - A simplified explanation of the abstract
This abstract first appeared for US patent application 18085346 titled 'SYSTEM AND METHOD FOR DIAGNOSING LACK OF COOLANT OF VEHICLE TO WHICH INTEGRATED THERMAL MANAGEMENT VALVE IS APPLIED
Simplified Explanation
The abstract describes a system for diagnosing lack of coolant in a vehicle that uses an integrated thermal management valve. The system includes multiple valves that control the distribution of coolant to different parts of the vehicle, such as the radiator, heater, and oil cooler. It also includes coolant temperature sensors installed at various points in the engine to measure the temperature of the coolant. A control unit monitors the coolant temperature difference between the engine block and the coolant outlet to determine if there is a decrease in coolant level. It also accumulates the temperature difference between the coolant outlet and the coolant inlet to further confirm if there is a lack of coolant.
- Integrated thermal management valve with multiple valves for coolant distribution
- Coolant temperature sensors at coolant inlet, coolant outlet, and engine block
- Control unit monitors coolant temperature difference to detect insufficient coolant level
- Accumulation of temperature difference between coolant outlet and coolant inlet for further confirmation
Potential Applications
- Automotive industry
- Engine cooling systems
- Vehicle diagnostics
Problems Solved
- Detecting lack of coolant in a vehicle
- Preventing engine damage due to insufficient coolant
- Improving vehicle maintenance and reliability
Benefits
- Early detection of coolant level issues
- Prevents engine overheating and potential damage
- Reduces maintenance costs and improves vehicle performance
Original Abstract Submitted
A system for diagnosing lack of coolant of a vehicle to which an integrated thermal management valve is applied according to the present disclosure includes an integrated thermal management valve including a plurality of valves which are openable and closable, and configured to selectively distribute coolant introduced from a head of an engine to front ends of a radiator, a heater, and an oil cooler, a coolant temperature sensor installed on each of a coolant inlet, a coolant outlet, and a block of the engine and configured to measure a temperature of the coolant, and a control unit configured to determine whether the coolant is insufficient by monitoring a decrease amount of a coolant temperature difference measured from the block and the coolant outlet, and finally determine whether the coolant is insufficient by accumulating an increase amount of a temperature difference between the coolant outlet and the coolant inlet.
