Abstract
A coolant control system of a vehicle includes first and second target flowrate modules, a target speed module, and a speed control module. The first target flowrate module determines a first target flowrate of coolant through an engine. The second target flowrate module, when a change in heat input to the engine is greater than a predetermined value, sets a second target flowrate to greater than the first target flowrate. The target speed module determines a target speed of an engine coolant pump based on the second target flowrate. The speed control module controls a speed of the engine coolant pump based on the target speed.
