    摘要： This control device for an engine provided with a fuel supply system capable of supplying liquefied natural gas to the engine as fuel comprises: a control unit for calculating a feedback adjustment value on the basis of a deviation between an actual fuel supply quantity and a target fuel supply quantity, and performing feedback control of the fuel supply system on the basis of the calculated feedback adjustment value; an acquiring unit for acquiring a methane number of the liquefied natural gas; a correcting unit for correcting the feedback adjustment value on the basis of the acquired methane number; and a failure diagnosis unit for performing failure diagnosis of the fuel supply system on the basis of the corrected feedback adjustment value. The engine control device can allow the failure diagnosis of the fuel supply system to operate normally.

    摘要： A charging system, a management terminal, a vehicle, a charging method, and a non-transitory computer-readable recording medium capable of inhibiting, by revising a charging plan, an effect of an interruption or the like due to occurrence of an error while charging control is being performed on the basis of the charging plan. The charging system includes a setting section that sets, based on a scheduled departure time and a target level of charge set for each of a plurality of vehicles, a charging plan including charging periods and charging times such that charging of the plurality of vehicles will be completed by the scheduled departure times, a control section that performs the charging in accordance with the plan, and a detection section that detects a charging error in one of the plurality of vehicles. The setting section revises the plan if the charging error satisfies a certain condition.

    摘要： An output control system includes: an accelerator pedal; a motor, for driving a vehicle, that increases the output as a depression amount of the accelerator pedal increases; a detent mechanism that increases resistance acting on the accelerator pedal at a position where the depression amount of the accelerator pedal reaches a predetermined depression amount that is smaller than a maximum depression amount of the accelerator pedal; a depression amount acquiring part that acquires the depression amount of the accelerator pedal; and a motor control part that controls the output of the motor such that the output of the motor becomes a predetermined power that is smaller than a maximum power of the motor when the depression amount acquired by the depression amount acquiring part is the predetermined depression amount.
