Abstract: A driving assistance device acquires data on a traveling situation, a travel speed, an inter-vehicle distance, an acceleration control, a braking control, and a steering control related to a nearby vehicle having a communication function. The driving assistance device detects a nearby vehicle having no communication function. The driving assistance device detects a traveling situation of the nearby vehicle having no communication function. The driving assistance device predicts a traveling state of the nearby vehicle having the communication function based on traveling situation data acquired by the vehicle data acquisition unit, and predicts a traveling state of the nearby vehicle having no communication function based on traveling situation data acquired by the traveling situation detector.

Abstract: A vehicular drawing device includes a first operating system, a second operating system, a first circuit block group, a second circuit block group, a first power circuit, a second power circuit, and a controller circuit. The first circuit block group is used in the first operating system. The second circuit block group is used in the second operating system. The first power circuit is configured to supply a sub power to the first circuit block group. The second power circuit is provided separately from the first power circuit, and the second power circuit is configured to supply a main power to the second circuit block group. In response to the main power being abnormal, the controller circuit is configured to (i) maintain supplying of the sub power from the first power circuit to the first circuit block group and (ii) terminate an operation of the second power circuit.

Abstract: A vehicle power supply device includes a voltage decrease circuit, a control unit, and a voltage increase power supply unit. The voltage decrease circuit includes multiple MOSFETs as switching elements, receives a voltage supplied from a battery, decreases, by turning on and turning off the switching elements, the received voltage to an operation voltage of an operation target device, and outputs the decreased voltage to the operation target device. The control unit controls an operation of the voltage decrease circuit. The voltage increase power supply unit is connected with the voltage decrease circuit in parallel, receives the voltage supplied from the battery, increases the received voltage, and outputs the increased voltage to the control unit.
