Abstract: An estimation system, includes: a secondary battery; a monitoring device that detects a voltage and a current of the secondary battery; and a processor that estimates a full charge capacity of the secondary battery using a detection result of the monitoring device. The processor calculates a first charging rate of the secondary battery using a current integration amount in charging, discharging, or charging and discharging of the secondary battery and using a full charge capacity of the secondary battery that was estimated last time; calculates a second charging rate of the secondary battery using an open circuit voltage of the secondary battery, when a predetermined time has elapsed without charging and discharging since the first charging rate is calculated; and performs correction, when a magnitude of a difference between the first and second charging rates is larger than a threshold, on the full charge capacity based on the difference.

Abstract: A vehicle includes: an engine; an exhaust pipe through which exhaust gas from the engine is released; a battery pack located near the exhaust pipe; and an ECU that executes, during limp-home traveling of the vehicle, control in which the battery pack is not charged and discharged, and output suppression control in which output of the engine is suppressed. In the output suppression control, when the catalyst temperature is above a threshold value, the ECU suppresses the output of the engine, as compared to when the catalyst temperature is below the threshold value, while maintaining a state in which the engine can output power.

Abstract: A vehicle includes an electronic control unit. The electronic control unit is configured to detect a first current value in a period in which a current path is switched to a non-conductive state by an ignition-off operation. The electronic control unit is configured to detect a second current value in a period that is after an ignition-on operation is performed and before the current path is switched from the non-conductive state to a conductive state in the case where the first current value falls out of a specified reference range. The electronic control unit is configured to diagnose that there is an abnormality of the current sensor when the second current value falls out of the reference range and to diagnose that there is no abnormality of the current sensor when the second current value falls within the reference range.
