における異常判断装置。 Work that involves installing a control unit equipped with an actuation part control mechanism that outputs an operation control command to an actuator for controlling the actuation part based on signals input from signal output means such as switches, setting devices, sensors, etc. In the commercial vehicle, the control unit outputs an operation control command set in advance to the actuator for controlling the actuator, in addition to the operation control command by the actuator control mechanism, and operates the actuator based on the actuator. What is claimed is: 1. An abnormality determination device for a work vehicle, comprising an abnormality determination mechanism that recognizes a change from a change in a detected value of a corresponding operation detection sensor and determines whether or not an abnormality exists based on this.
