The invention provides a vehicle instrument device with excellent versatility. A meter (200), which is mounted on a vehicle and displays a physical quantity related to the vehicle on the basis of an input signal, is provided with: a display unit that displays the physical quantity; a microcomputer (210) that controls the display unit on the basis of the signal; and a single connector (connection terminal) that corresponds to the input of both a first signal based on a CAN protocol (first communication protocol) and a second signal based on a UART protocol (second communication protocol), the microcomputer (210) executes: a step (S3) (first determination operation) that determines whether or not the signal is the first signal; and a step (S8) (second determination operation) for determining whether or not the signal is a second signal.
本发明提供一种通用性优异的车辆用仪器装置。仪表(200)被搭载于车辆,根据所输入的信号,显示与车辆有关的物理量,其中,具有:显示部,其显示物理量;微型计算机(210),其根据信号,对显示部进行控制;以及单一的连接器(连接端子),其与基于CAN协议(第一通信协议)的第一信号和基于UART协议(第二通信协议)的第二信号这两方的输入相对应,微型计算机(210)执行:步骤(S3)(第一判定动作),其判定信号是否为第一信号;以及步骤(S8)(第二判定动作),其判定信号是否为第二信号。
