METHOD AND SYSTEM FOR COOLING WATER CONTROL OF VEHICLE
First Claim
Patent Images
1. A method for a cooling water control of a vehicle, comprising:
- detecting, by a controller, a flow rate of cooling water and comparing the detected flow rate with a preset normal flow rate value; and
when the detected flow rate of cooling water is less than the preset normal flow rate value, increasing, by the controller, a cooling water pump speed command until a power average value of a cooling water pump reaches a reference power value when the cooling water is normally circulated to increase revolutions per minute (RPM) of the cooling water pump.

Abstract
A system and method for a cooling water control of a vehicle are provided. The method for a cooling water control of a vehicle includes detecting a flow rate of cooling water and comparing the detected flow rate with a preset normal flow rate value. When the detected flow rate of cooling water is less than the preset normal flow rate value a cooling water pump speed command is increased until a power average value of the cooling water pump reaches a reference power value when the cooling water is normally circulated to increase an RPM of the cooling water pump.

10. A system for a cooling water control of a vehicle, comprising:
-
a memory configured to store program instructions; and a processor configured to execute the program instructions, the program instructions when executed configured to; detect a flow rate of cooling water and comparing the detected flow rate with a preset normal flow rate value; and increase a cooling water pump speed command until a power average value of a cooling water pump reaches a reference power value when the cooling water is normally circulated to increase revolutions per minute (RPM) of the cooling water pump when the detected flow rate of cooling water is less than the preset normal flow rate value. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
