Embodiment Construction

[0021] Thermal management of prime movers (such as, for example, engines, motors, battery packs, etc.) in vehicle propulsion systems can be critical for optimal performance, reliability, and durability. figure 1 A thermal management system 100 in a vehicle propulsion system is illustrated. The thermal management system includes a prime mover 102 that provides power to the vehicle propulsion system. For example, prime mover 102 may be an internal combustion engine, an electric motor, etc. (without limitation). Operation of prime mover 102 may require temperature management to optimize efficiency, economy, performance, and the like. The thermal management system 100 circulates coolant throughout the system 100 in a manner that enables the temperature of the engine to be managed, as generally indicated by arrows 104 . Coolant exits the engine 102 at a coolant outlet 106 and flows to an inlet 108 of a coolant control valve 110 . The coolant control valve 110 communicates with a...

Abstract

A vehicle propulsion system includes a prime mover having a coolant inlet and a coolant outlet, a coolant control valve having a valve inlet in communication with the prime mover coolant outlet, a first valve outlet, and a second valve outlet, a bypass flow path in communication with first valve outlet and the prime mover coolant inlet, a heat exchange flow path in communication with the second valve outlet and the prime mover inlet, a heat exchanger in the heat exchange flow path, a first temperature sensor in the bypass flow path for generating a first temperature signal, a second temperature sensor in the heat exchange flow path for generating a second temperature signal, and a controller for providing a coolant control valve command signal to the coolant control valve, using a normalized gain coefficient.

Description

technical field [0001] The present disclosure relates to a method and system for coolant temperature control in a vehicle propulsion system. Background technique [0002] This section generally presents the context of the disclosure. The work of the presently named inventors, to the extent they are described in this section, and aspects of that description that may not otherwise be considered prior art at the time of filing, are neither expressly nor impliedly is considered to be prior art with respect to the present disclosure. [0003] Vehicle propulsion systems may include thermal management systems that regulate the temperature of a prime mover, such as an internal combustion engine. Temperature management of internal combustion engines can be important to optimize fuel economy, efficiency, reliability, and durability not only of the engine but of the entire system. [0004] Many thermal management systems for vehicle propulsion systems rely on coolant flow through th...
