摘要
十年前整车上由发动机控制器(ECU)、变速箱控制器(TCU)、车身控制器(BCM)等三大主要控制器,控制器数量较少,基本跟随发动机和变速箱同步开发,未设定单独软件开发控制流程.随着智能座舱、智能驾驶、智能控制等整车智能化、科技化程度的不断提升,功能"软件定义汽车"一词逐渐被各大主机厂意识到"软件"开发在整车开发中的重要性.文章重点讲述目前整车近百个控制器,如何做到功能需求拉起、软件发布符合整车试制和投产等节点要求.
Abstract
Ten years ago,the entire vehicle was equipped with three main controllers:engine control unit(ECU),transmission control unit(TCU),and body control module(BCM).The number of controllers was relatively small,and they were basically developed synchronously with the engine and transmission,without setting up a separate software development control process.With the continuous improvement of vehicle intelligence and technology such as intelligent cockpit,intelligent driving,and intelligent control,the term"software defined car"has gradually been recognized by major automakers as the importance of"software"development in vehicle development.This article focuses on how to achieve functional requirements and software release that meets the requirements of vehicle trial production and production,among nearly a hundred controllers in the current vehicle.
