摘　　要：在电气控制单元功能验证阶段,传统的测试方法往往是在试验台架上进行电气控制单元的功能测试,对测试环境的要求比较高。为避免对测试环境的依赖,本文设计一种利用CANoe软件模拟控制单元的测试方法。以测试某车型的仪表显示车身信息功能为例,先利用CANoe软件建立数据库和控制面板,然后连接硬件设备,搭建软件测试仿真环境,模拟车身控制单元节点发送总线报文信号,验证仪表即时显示车身信息的功能。结果表明,本文设计的方法在不依赖测试环境的情况下也可较好地完成功能测试。In the state of ECU function test, the traditional way is that the function is tested on the test bench, therefore the traditional test way relies on the test bench. In order to avoid the dependence, the design of test way by CANoe simulating ECU is introduced in the paper. Taking the function test of IC displaying the information for example, firstly, the function database and panel is created, then the hardware devices are connected, and the BCM CAN message is simulated and transmitted to IC, the IC displays the information according to the message. The result shows that the way can well complete the function test.
