Objective of the vehicle thermal management system is to achieve precise coolant temperature control that ensures operation of the combustion engine in the region with the maximum thermal efficiency. In this study it is achieved by a combined effect of coolant temperature control algorithm that is operating an advanced electronic valve with one input and three outputs that balances distribution of the coolant flow between the heat source and sink components. The objective is to present an application of a nonlinear model predictive control (NMPC) approach for coolant temperature control. It is a simulation study to quantify benefits of precise coolant temperature control with the possible inclusion of preview information.
