Problems solved by technology

However, under severe operating conditions, the engine requires increased coolant flow to maintain proper component temperatures
If a high flow rate coolant pump is used under severe conditions to provide a high coolant flow rate to prevent overheating, the amount of coolant flow would be excessive under normal operating conditions, causing parasitic energy losses in the engine and transmission

Abstract

A vehicle powertrain thermal management system for distributing thermal energy to vehicle powertrain components including an engine and a transmission. A system for managing thermal energy includes a coolant pump, a first control valve, a second control valve, a radiator, a heater core, and a transmission oil heat exchanger. The first control valve has an inlet in fluid communication with the engine coolant outlet. The first control valve also has a first control valve outlet. The second control valve has a first inlet, a second inlet, a first outlet, a second outlet and a third outlet. Thermal energy generated by the engine is delivered to the radiator by the control of the first control valve, and delivered to at least one of the heater core and the transmission oil heat exchanger by the control of the second control valve.

Description

technical field [0001] The present invention relates to coolant circuits for automotive powertrain systems, and more particularly to systems and methods for managing heat generated by automotive engines to increase the overall efficiency of the powertrain. Background technique [0002] The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art. [0003] A typical powertrain of an automobile consists of an engine and a transmission. The coolant system is used to keep the engine from overheating. The coolant system includes a coolant pump that provides a fluid, such as engine coolant, to various engine and transmission components, including heat exchangers, via a plurality of fluid communication lines. Typically, heat is transferred from the engine to the coolant via a coolant jacket, which surrounds the combustion-heating components of the engine. The heat absorbed by the circulating coolan...
