More Information
Summary:The invention provides a cooling system having an electrically adjustable control element for influencing the coolant temperature of internal-combustion engines in motor vehicles. The system according to the invention has an electronic controller which is connected in front of the control element and which, at least as a function of a quantity influenced by the coolant temperature, generates the control signal quantity for the control of the control element for reaching a desired coolant temperature. The parameters of the controller are determined by means of a basic characteristic diagram and at least one characteristic correction diagram.
