The embodiment of the invention provides a vehicle electronic instrument testing tool and an electronic instrument testing method, and relates to the technical field of electronic instrument testing. The electronic instrument testing method is based on a vehicle electronic instrument testing tool, and the vehicle electronic instrument testing tool comprises a main control module, a first power supply module, a signal conditioning module and a second power supply module. Wherein the master control module is used for receiving an instruction of a user, the signal conditioning module and the master control module are arranged at an interval and are in communication connection, and the signal conditioning module is used for sending out a corresponding analog interference signal according to a signal of the master control module, the first power supply module is connected with the master control module and is used for supplying power to the master control module, and the second power supply module is connected with the signal conditioning module. The power supply module supplies power to the signal conditioning module. The load power supply of the whole vehicle is simulated through the second power supply module so as to simulate the working condition of the electronic instrument when the battery of the whole vehicle is lack of power, simulation test can be carried out when the load power supply is lack of power, whole vehicle test in a main engine plant is avoided, and the development efficiency of the electronic instrument is improved.

    本发明的实施例提供了一种车辆电子仪表测试工装及电子仪表测试方法,涉及电子仪表测试技术领域。其中电子仪表测试方法基于车辆电子仪表测试工装,车辆电子仪表测试工装包括主控模块、第一电源模块、信号调理模块及第二电源模块。其中主控模块用于接收用户的指令,信号调理模块与主控模块间隔设置且通讯连接,用于根据主控模块的信号发出相应的模拟干扰信号,第一电源模块与主控模块连接,用于向主控模块供电,第二电源模块与信号调理模块连接,用于向信号调理模块供电。通过第二电源模块模拟整车的负载电源,以模拟电子仪表在整车电池亏电时的工况,可以在负载电源亏电时进行模拟测试,以避免到主机厂进行整车测试,提高了电子仪表的开发效率。
