Abstract
A vehicle propulsion system includes an engine having a coolant inlet and a coolant outlet, a coolant pump having an outlet in communication with the engine coolant inlet, a pressure sensor in fluid communication with the engine coolant outlet and that generates a pressure signal indicative of a pressure in the engine coolant outlet, and a controller in communication with the pressure sensor and the coolant pump. The controller is programmed to control a flow of coolant through the engine from the coolant pump based upon the pressure signal.

A thermal management system for a vehicle propulsion system, the system comprising:
- an engine having a coolant inlet and a coolant outlet;
- a coolant pump having an outlet in communication with the engine coolant inlet;
- a pressure sensor in fluid communication with the engine coolant outlet and that generates a pressure signal indicative of a pressure in the engine coolant outlet;
- and
- a controller in communication with the pressure sensor and the coolant pump, wherein the controller is programmed to control a flow of coolant through the engine from the coolant pump based upon the pressure signal.
A method for thermally managing a vehicle propulsion system which includes an engine having a coolant inlet and a coolant outlet, a coolant pump having an outlet in communication with the engine coolant inlet, and a pressure sensor in fluid communication with the engine coolant outlet that generates a pressure signal indicative of a pressure in the engine coolant outlet, the method comprising controlling a flow of coolant through the engine from the coolant pump based upon the pressure signal.
