Abstract: Aspects of the disclosed technology include techniques, a mechanism, and an apparatus for diagnosing a battery. One or more processors may measure voltages of a plurality of batteries and, based on the measured voltages, determine a voltage deviation of the plurality of batteries. The one or more processors may determine a voltage deviation variation of each battery of the plurality of batteries at predetermined times periods and may compare a pattern of the voltage deviation variations of each battery of the plurality of batteries with a preset diagnosis pattern to diagnose a state of each of the plurality of batteries.

Abstract: The present invention relates to a method and apparatus for controlling synchronization of camera shutters in an in-vehicle Ethernet communication network. A method for controlling synchronization of a camera shutter by a camera controller cooperating with a grandmaster through Ethernet communication may include performing a time synchronization procedure with the grandmaster, reducing a preset pulses per second (PPS) down counter if the time synchronization procedure is successfully completed, and operating the camera shutter when the PPS down counter reaches 0. Accordingly, the present invention may provide accurate image frames of a desired time through synchronization of shutters of cameras connected to an in-vehicle Ethernet network.
