  • Patent number: 9634498
    Abstract: An electrical storage system includes electrical storage elements connected in series with each other and being charged or discharged; discharge circuits respectively connected in parallel with the electrical storage elements and discharging the corresponding electrical storage elements; and a controller controlling operations of the discharge circuits. The controller calculates a first SOC difference using a full charge capacity of each electrical storage element. The first SOC difference is a difference in SOC between the electrical storage elements and arises due to a difference in full charge capacity between the electrical storage elements. The controller calculates a second SOC difference that is a difference in SOC between the electrical storage elements at the moment the second SOC difference is calculated.

  • Patent number: 9632191
    Abstract: Disclosed is a sound source detection device 1 which compares information of sound collected by sound collectors 13, 14, 15, and 16 to detect a predetermined sound source. The sound source detection device 1 includes a target determination unit 22 which arranges sound collectors at the same distance from a noise source inside a mobile object to determine a detection-target region of a sound source, and a sound source detection unit 25 which detects the direction of the predetermined sound source using information of sound of the detection-target region determined by the target determination unit 22. Accordingly, the sound source detection unit 25 does not determine sound input to the sound collectors 13, 14, 15, and 16 at the same timing as a detection target, making it possible to eliminate the influence of a noise source other than a sound source inside the mobile object in advance.

    Abstract: Provided is a vehicle system constituted by a master ECU and a general ECU. The general ECU attaches a digital signature to transmission data including the data (for example, a digest value of a program) and transmits the transmission data to the master ECU. The master ECU verifies the digital signature and the data and, when both the digital signature and the data are valid, determines that the general ECU is valid. The master ECU attaches a digital signature to transmission data including the data of the master ECU and a session key and transmits the transmission data to the general ECU. The general ECU verifies the digital signature and the data and, when both the digital signature and the data are valid, the general ECU uses the session key included in the transmission data as a common key when performing subsequent communications.

  • Publication number: 20170107930
    Abstract: An electronic control unit includes a seat temperature calculating unit, a supply amount control unit, and a concentration acquiring unit. The seat temperature calculating unit calculates a simulated temperature of an exhaust valve seat. When the simulated temperature of the exhaust valve seat becomes equal to or higher than a threshold temperature, the supply amount control unit starts fuel increase control of increasing a lower limit value of an amount of fuel to be supplied into a cylinder to a larger value than that before the simulated temperature becomes equal to or higher than the threshold temperature. The concentration acquiring unit acquires an ethanol concentration of the fuel. In the fuel increase control, the supply amount control unit makes the amount of increase in the lower limit value larger as the ethanol concentration of the fuel acquired by the concentration acquiring unit is higher.
