The invention discloses a diagnosis method, a diagnosis box, an electronic control unit (ECU), electronic equipment and a storage medium. The method comprises the steps that the diagnosis box receives a first diagnosis request for the ECU from vehicle diagnosis equipment; if the diagnosis box receives a second diagnosis request for the ECU within a preset time length, the diagnosis box performs frame splicing on the first diagnosis request and the second diagnosis request to obtain a target diagnosis request; the diagnosis box sends a target diagnosis request to the ECU; the ECU analyzes the target diagnosis request to obtain first diagnosis data and second diagnosis data; and the ECU executes a first diagnosis function corresponding to the first diagnosis data and executes a second diagnosis function corresponding to the second diagnosis data. According to the invention, the communication efficiency during vehicle diagnosis can be improved.
本申请公开了一种诊断方法、诊断盒、电子控制单元、电子设备及存储介质,该方法包括:诊断盒从车辆诊断设备接收针对电子控制单元ECU的第一诊断请求;若诊断盒在预设时长内接收到针对ECU的第二诊断请求,则诊断盒将第一诊断请求和第二诊断请求进行拼帧,得到目标诊断请求;诊断盒向ECU发送目标诊断请求;ECU对目标诊断请求进行解析,得到第一诊断数据和第二诊断数据;ECU执行第一诊断数据对应的第一诊断功能,以及执行第二诊断数据对应的第二诊断功能。本申请有利于提升车辆诊断时的通信效率。
