PROBLEM TO BE SOLVED: To provide an in-vehicle device capable of effectively learning a satisfactory operational state.SOLUTION: A digital tachograph 10A has a normal mode and a training mode, and when a crew operates a training button SW input part 30, accepts the setting of the training mode, and switches the normal mode to the training mode. In the training mode, the digital tachograph 10A positively and negatively evaluates an operational state, and integrally evaluates the operational state on the basis of the evaluation result. The operational state to be evaluated in the training mode includes all the operation states to be evaluated in the normal mode. |
