Abstract: A system and method for controlling a current draw in a transport refrigeration system (TRS) including an electronically controlled engine having an engine control unit (ECU) are disclosed. The method includes disabling the ECU in response to the electronically controlled engine entering an operating mode in which the electronically controlled engine is not running. The TRS controller determines an ambient temperature based on a temperature outside an internal space of the refrigerated transport unit. The TRS controller initializes an ECU off timer when the ambient temperature is less than or equal to an ambient temperature threshold.

Abstract: The embodiments described herein allow a user device to communicate with one or more components within a TRS via a single point communication scheme. That is, a single point access coordinator of a TRS can be configured to receive a message from a user device via a commercial grade communication link, process the message (e.g., determine which TRS component the message is intended for, determine whether the message is a proper message, unpack the message from a commercial grade communication protocol, repack the message into a rugged industrial grade communication protocol, etc.) and relay that message to one or more components of the TRS via a rugged industrial grade communication link within the TRS.

Abstract: A data communication protocol used to transfer data and/or files between various components in a TRS and/or used to transfer data and/or files between a TRU system and various consumer electronics employs a common communication protocol as a wrapper around various existing and future data transfer protocols. The transferred data and/or files are presented in an instruction set document format. The data communication protocol allows migration of current communication protocols and methods to modern, high speed communication buses and uses a defined generic data structure that accommodates a substantially non-exhaustive number of predetermined services that are supported by components associated with the TRS.
