  • Publication number: 20230420971
    Abstract: An electric power source control device includes an acquisition unit that acquires a charging/discharging current of a low-voltage battery, a detection unit that detects a predetermined operation executed with respect to a high-voltage battery, and a determining unit that determines presence/absence of an abnormality with respect to a connection state of the low-voltage battery, based on the charging/discharging current. When the predetermined operation is detected, the determining unit determines whether a state in which the charging/discharging current is no greater than a first threshold value continues for a first duration of time, controls an electric power converter when the state continues for the first duration of time, and further determines whether the state continues for a second duration of time longer than the first duration of time, and determines that the connection state of the low-voltage battery is abnormal when the state continues for the second duration of time.

  • Publication number: 20150301879
    Abstract: In a serial communication circuit, a data extracting section extracts reception data based on a reception clock signal with maximum speed. A pattern determining section compares a reception bit pattern of the reception data corresponding to a characteristic pattern and each of a plurality of detection bit patterns for the characteristic pattern, and indicates when the reception bit pattern matches one of the detection bit patterns. A periodicity determining section determines a period when the reception bit pattern matches the detection bit pattern, based on the pattern match indication, detects that the detection bit pattern emerges continuously in a stream of the reception data every the period, and determines a generation difference between transmission and reception speeds based on the detection bit pattern. A transmission rate setting section determines the transmission speed of a connected device transmitting the reception data based on the generation difference and maximum speed.
