Abstract: A system according to the principles of the present disclosure includes a temperature estimation module and a coolant flow control module. The temperature estimation module can determine an estimate of a heater core air out temperature of a vehicle based upon a heater core inlet coolant temperature, a heater core outlet coolant temperature, an estimated volumetric air flowrate, and an estimated volumetric coolant flowrate. The coolant flow control module can control a rate at which coolant flows to a heater core of the vehicle by adjusting a position of a coolant control valve of the vehicle or an output of a coolant pump of the vehicle. The coolant flow control module can control the coolant flowrate to decrease a difference between a target heater core air out temperature and the estimated heater core air out temperature.

Abstract: A system includes a temperature error module and a coolant flow control module. The temperature error module determines an error between a target air temperature and a measured air temperature of a duct that supplies air to a cabin of a vehicle. The coolant flow control module controls a rate at which coolant flows to a heater core of the vehicle by adjusting at least one of a position of a coolant control valve of the vehicle and an output of an electric coolant pump of the vehicle. The coolant flow control module also controls the coolant flow rate to decrease the error between the target air temperature and the measured air temperature.
