摘　　要：当今汽车行业发展势头迅猛,汽车控制器算法更新迭代迅速,软件刷写测试也变得愈发频繁。然而,目前市面上的刷写上位机大多基于UDS协议,针对单个控制器进行专用设计,无法实现汽车各控制器的通用化,因此,主机厂亟待一种可移植且通用的刷写工具。文章基于CANoe软件,结合主机厂的UDS刷写流程,完成一款通用上位机的设计。该工具集成检查编程条件、检验刷写可靠性、CRC校验等一系列校验机制,有效确保软件刷写的准确性。最后,通过实际案例对该设计的可靠性进行验证。With the rapid development of automobile industry,the update iteration of automobile controller algorithm is rapid,and the software rewrite test is becoming more and more frequent.However,most of the brush writing host computers on the market are based on the UDS protocol and designed specifically for a single controller,which cannot realize the universality of each controller of the automobile.Therefore,the Oems need a portable and universal brush writing tool.Based on CANoe software and UDS scrub process of OEMS,a universal upper computer is designed in this paper.The tool integrates a series of checking mechanisms such as checking programming conditions,checking the reliability of writing,CRC checking,etc.,which effectively ensures the accuracy of software writing.Finally,the reliability of the design is verified by a practical case.
