摘要
汽车控制器由于要实现的功能复杂,其开发周期长,开发成本高,因此,本文提出了一种基于GPRS和CAN总线的整车控制策略远程监测系统,支持远程创建测试用例和云端数据存储。为避免网络延迟对整车控制策略远程监测的影响,该系统将测试用例先发送到现场终端设备后再逐一发送监测请求报文。详细描述了监测系统软件的设计实现方法,并介绍了系统的构成,提出了基于CAN总线、SD存储和GPRS无线数据传输的监测终端设计方案。最后通过CANTest软件模拟硬件在环中控制器进行CAN报文的收发工作,系统经过试验测试,运行稳定,支持多测试终端的连接且具有较高的实时性,有助于提高整车控制器的硬件在环设备的利用率和汽车ECU的开发效率。
Due to the complex functions to be implemented,the development cycle of automobile controllers is long and the development cost is high.Therefore,this paper proposes a remote monitoring system for vehicle control strategies based on GPRS and CAN bus,which supports remote creation of test cases and cloud data storage.In order to avoid the influence of network delay on the remote monitoring of the vehicle control strategy,firstly,the system sends the test cases to the on-site terminal equipment,then sends the monitoring request messages one by one.The design and implementation method of the monitoring system software is described in detail,and the composition of the system is introduced.A monitoring terminal design scheme based on CAN bus,SD storage and GPRS wireless data transmission is proposed.Finally,CANTest software is used to simulate the hardware-in-the-loop controller to send and receive CAN messages.After experiment test,the system runs stably.The system supports the connection of multiple test terminals,has high real-time performance,and helps to improve the utilization rate of hardware-in-the-loop equipment and the development efficiency of automotive ECUs.
