摘要
为了实现汽车ECU的远程更新功能,基于现有的WIFI/3G以及蓝牙无线通信技术,提出了一种利用智能手持设备为中介,接受远端服务器发来的固件包,并发送给相应车载平台,再由车载平台通过汽车CAN网络将固件包传送给汽车ECU并实现更新的方案。在此方案的基础上,通过对功能的需求进行分析,确定了车载平台的功能模块并进行了相应的设计。该车载平台主要采用以K60N512芯片为核心,系统主要包括CAN模块、蓝牙模块、电源模块等。基于此方案设计的硬件平台,具有功耗低、模块精简、便于适配的优点。
In order to realize vehicle ECUs＇ remote updating, this paper presents a solution which can complete the remote updating in the car. This solution based on WIFI/3G and Bluetooth,using smart phone/pad receive the firmware package from remote server. Then send the firmware package to corresponding vehicle platform. The platform will transmit the firmware package to vehicle ECU through CAN network and complete the updating after that. According to this solution,the paper identifies the function modules and completes the hardware design. This vehicle platform uses K60NS12 as the core chip. The system contains CAN module, Bluetooth module, power module, et al. It has simple structure,low power consumption and is easy to adapt to the car.
