Techniques for controlling energy consumption and enhancing systemic efficiency through management of thermal devices for electrified vehicles

Abstract

A control and thermal management method for an electrified vehicle includes, in response to a valid wakeup request, transmitting, by a supervisory controller and via a local interconnect (LIN) bus, timing instructions for operation of a set of thermal systems powered by low voltage battery, in response to an ignition-off request, commanding, by the supervisory controller and via the LIN bus, a request for the set of thermal systems to complete their existing functions within a calibratable period, and in response to a function completion confirmation from the set of thermal systems, commanding, by the supervisory controller, the LIN bus and the set of thermal systems to shutdown, thereby avoiding a communication delay or a malfunction that could result in the set of thermal systems remaining active after the LIN bus is shutdown.
