Abstract
The present invention relates to a method of controlling an electronic thermostat valve that is based on the driving conditions. The method includes using controlling parameters memorized in an ECU (Electronic Control Unit). A power source to activate the thermostat valve is originated from an expanding force of a thermal element and a change of stroke of an actuating means. A cooling system of a vehicle can be maintained in an optimized state such that fuel consumption and exhaust pollutants are reduced.
