US 2026/0168431 A1 · METHOD OF DETERMINING COOLANT SHORTAGE AND ENGINE COOLING SYSTEM USING THE SAME

Abstract

Disclosed is an engine cooling system, which includes: a water temperature controller assembly (WTCA) coupled to an engine of a vehicle to control a flow of a coolant discharged from the engine; and a first temperature sensor. The first temperature sensor may be configured to: measure one or more temperatures of the coolant discharged from the engine; and generate one or more signals indicating the one or more measured temperatures of the coolant. The engine cooling system may further include a processor configured to: receive the one or more signals; determine a highest coolant temperature measured during a first time period; determine, based on the highest coolant temperature measured during the first time period, whether an amount of the coolant is below a threshold coolant level; and send, based on a determination that the amount of the coolant is below the threshold coolant level, a signal to the vehicle.

An engine cooling system comprising:

a water temperature controller assembly (WTCA) coupled to an engine of a vehicle to control a flow of a coolant discharged from the engine;
a first temperature sensor comprising a portion that penetrates into an interior of the WTCA, wherein the first temperature sensor is configured to:
measure one or more temperatures of the coolant discharged from the engine;
and
generate one or more signals indicating the one or more measured temperatures of the coolant discharged from the engine;
and
a processor configured to:
receive the one or more signals;
determine, based on the one or more measured temperatures of the coolant discharged from the engine, a highest coolant temperature measured during a first time period;
determine, based on the highest coolant temperature measured during the first time period, whether an amount of the coolant is below a threshold coolant level;
and
send, based on a determination that the amount of the coolant is below the threshold coolant level, a signal to the vehicle.

A method comprising:

obtaining, by a processor via a first temperature sensor, one or more temperatures of a coolant discharged from an engine of a vehicle into a water temperature controller assembly (WTCA) of the vehicle;
determining, based on the one or more temperatures of the coolant discharged from the engine, a highest coolant temperature measured during a first time period;
determining, after the first time period ends and based on the highest coolant temperature measured during the first time period being greater than or equal to a threshold temperature, that an amount of the coolant is below a threshold coolant level;
and
sending, based on the determining of the amount of the coolant being below the threshold coolant level, a signal to the vehicle.
