FAILURE DETERMINING DEVICE, AND FAILURE DETERMINATION DATA ACQUIRING DEVICE

This failure determining device is provided with a first determining unit which refers to correction amount data indicating a correction amount relating to operation of a part related to an internal-combustion engine, to determine whether there is a possibility that the internal-combustion engine has failed, a data acquiring unit which, if it has been determined that there is a possibility that the internal-combustion engine has failed, acquires influencing factor data indicating a factor influencing the correction amount, and a second determining unit which refers to the correction amount data together with the acquired influencing factor data to determine whether the internal-combustion engine has failed. 本发明提供一种故障判断装置，其具备：第一判断部，参照表示内燃机相关部位的动作的修正量的修正量数据，判断是否有可能发生了内燃机的故障；数据获取部，在判断为有可能发生了内燃机的故障时，获取表示影响修正量的因素的影响因素数据；以及第二判断部，同时参照修正量数据和所获取的影响因素数据，判断内燃机是否有故障。
