摘　　要：由于汽车ECU程序尺寸越来越大,所以通过传统的CAN网络来实现ECU升级必将花费较长的时间。因此,使用一种可靠、稳定、高效的升级方法十分必要。为了解决当前汽车ECU程序升级速度慢的问题和改善ECU程序的升级环境,提出一种基于QNX/Linux操作系统的ECU安全升级方法,即OTA升级或通过USB存储设备来升级。针对该方法基于QNX操作系统并利用USB存储设备实现了ECU程序的快速升级,并设计了一套模拟整车升级风险的实验,验证了该ECU升级模式的可行性和可靠性。Due to the increasing size of automotive ECU programs,it will take a long time to implement ECU upgrades through traditional CAN networks.Therefore,it is necessary to use a reliable,stable and efficient upgrade method.In order to solve the problem of slow upgrade of current automotive ECU programs and improve the upgrade environment of ECU programs,an ECU security upgrade method based on QNX/Linux operating system is proposed,namely OTA upgrade or upgrade via USB storage device.For this ECU upgrade method,the QNX-based ECU security upgrade practice was performed using a USB storage device,and a set of experiments simulating the whole vehicle upgrade risk is designed to verify the feasibility and reliability of the ECU upgrade mode.
