AI Technical Summary

Technical Problem

Existing electronic control unit (ECU) connectivity architectures have limitations in prime mover systems in terms of complexity, number of components, compatibility, cybersecurity, robustness, and cost, and therefore need to be improved.

Method used

Employing a unique ECU connectivity architecture, it utilizes a multi-OS integrated circuit (multi-OS IC) to achieve parallel operation of a real-time operating system (real-time OS) and an edge operating system (edge ​​OS). The real-time OS provides predictable and deterministic control, while the edge OS performs performance analysis and prediction, eliminating the need for encoding/decoding and encryption/decryption, and enabling efficient communication within the system.

Benefits of technology

It improves the communication efficiency and robustness of the prime mover system, reduces the complexity and cost between ECUs, enhances network security, and improves the system's analytical and predictive capabilities.

Abstract

A prime mover system includes: a prime mover located in a prime mover compartment and configured to output power to drive a load; an intra-system communication network; and a first electronic control unit located in the prime mover compartment and operatively coupled to the intra-system communication network. The first electronic control unit is configured to run a real-time operating system stored in a first set of non-transitory memory locations to control the operation of the prime mover; and the first electronic control unit is configured to run an edge computing operating system stored in a second set of non-transitory memory locations to receive prime mover operation information from the real-time operating system, process the received prime mover operation data to determine performance analysis, store the performance analysis in a third set of non-transitory memory locations, encode the performance analysis, and transmit the encoded performance analysis via the intra-system communication network.
