Abstract
Various embodiments of the teachings herein include a method for operating a valve comprising: determining a nonlinear characteristic curve function indicating a required relationship between a valve opening position and flow of a fluid; storing the function in an ECU; and using the function to set the valve opening position with a control signal indicating a target flow. The function is calculated automatically using a parameter value, with an analytic function, or by interpolation with specified supporting values by a user. The function comprises an inverse function based on a characteristic curve for a heat exchanger and a target function. The curve for the heat exchanger indicates a relationship between a heating power or a cooling power and the flow of a fluid. The target function indicates a relationship between the heating power or the cooling power of the heat exchanger based on the valve opening position. The characteristic curve for the heat exchanger depends on the same parameter value as the characteristic curve function.
