Distributed state machine and vehicle-mounted distributed system

Abstract

The invention provides a distributed state machine and a vehicle-mounted distributed system. The distributed state machine is characterized by comprising a vehicle-mounted side state machine and a mobile side state machine; the vehicle-mounted side state machine is positioned in a vehicle-mounted central control host computer; the mobile side state machine is positioned in mobile equipment; the vehicle-mounted side state machine and the mobile side state machine correspondingly comprise input triggering modules, functional domain judging modules, mode judging modules, function operation modules and state executing modules; and at least one pair of modules in the input triggering modules, the functional domain judging modules, the mode judging modules, the function operation modules and thestate executing modules on the vehicle-mounted side and the mobile side communicate with each other through a two-way transmission protocol. Therefore, an interconnection mode design correspondinglyintegrates advantages of a smartphone and a vehicle machine, efficiently utilizes hardware resources of the vehicle-mounted central control host computer and the smartphone and meets different characteristics of iterative life cycles of the smartphone and the vehicle-mounted host computer.

Description

technical field [0001] The invention belongs to the field of automotive electronics, in particular to a distributed state machine in the field of distributed state machines and a vehicle-mounted distributed system. Background technique [0002] Compared with the consumer electronics industry, the industrial scale, development cycle and product iteration cycle of automotive electronics are far behind the consumer electronics industry. At the same time, due to the relatively high R&D threshold and quality requirements of automotive electronics, and the long verification and testing time, new automotive electronics developed by automakers Functional or new optimized products have a relatively long time to launch on the market; on the other hand, although automotive electronics products for the automotive aftermarket can properly solve the problem of new products and new function iteration cycles, due to the non-standardized operation of products in the aftermarket, And it is ...

AI Technical Summary

Problems solved by technology

[0004] As a type of mobile terminal, smart phones have many modes and related products for their interconnection in the vehicle central control host system. The current interconnection methods between mobile devices and vehicle devices in the market mainly include: Bluetooth hands-free connection, Screen projection mapping (mirrolink), data sharing (address book, SMS, email, etc.), Carplay, androidAUTO, etc., the state machine of traditional automotive electronics has been unable to meet the needs of vehicle-machine interconnection and access
