System and method for controlling a coolant flow by means of a motor with the use of a feedforward - projection and a feedback - projection

摘要

A system according to the principles of the present disclosure includes a heat transmission rates module by means of a module for a desired flow rate, a through flow rate no control module and a pumping expensive module. By means of the heat transmission rates module determines a rate of heat transfer from a motor to coolant, which flows through the motor, based on a cylinder wall temperature and a measured coolant temperature. The desired flow rate is determined by a desired rate of coolant flow through the engine based on the heat transfer rate. The through flow rate no control module determines a coolant through flow rates adjustment based on a desired coolant temperature and the measured coolant temperature. The pumps expensive module controls a coolant pump, is an actual rate of coolant flow through the engine based on the desired coolant through flow rate and the coolant flow rates to be set by setting.
