    摘要: Electronic devices include: a first electronic device capable of being always supplied with power; and a second electronic device capable of being supplied with the power through an operation by an occupant. Each of power supply hubs is located near the first electronic device, and connected to a battery or another one of the power supply hubs by one of main power supply lines. Each of the first and second electronic devices is connected to nearby one of the power supply hubs. Each of zone ECUs outputs a control signal to one of power supply ICs so as to distribute, to the first and second electronic devices, the power supplied to one of the power supply hubs by one of the main power supply lines.

    摘要: A vehicle control system includes a central ECU configured to calculate target outputs of actuators, and relay devices each disposed in a communication path between the central ECU and a corresponding actuator among the actuators. The plurality of relay devices includes a specific relay device configured transfer a control signal from the central ECU only to a fixed actuator that is an actuator not related to driving control, braking control, and steering control of a vehicle. The specific relay device is configured to output, to the fixed actuator coupled to the specific relay device, one of a signal for setting the fixed actuator in an operating state or a signal for setting the fixed actuator in a non-operating state, in response to detection of an abnormality in the central ECU. The specific relay device does not have a function of diagnosing an abnormality in the specific relay device.

    摘要: A network hub device used for building a simple network configuration in an in-vehicle network system is provided. A network hub device (22) is provided in a vehicle body and is coupled to a trunk network through which a digital control signal is transmitted. A sub hub device (241, 242) performs input/output of a signal to/from an in-vehicle device provided in a partial body assembled to the vehicle body via a movable portion. The sub hub device (241, 242) is provided in the partial body and the digital control signal is transmitted/received between the sub hub device (241, 242) and the network hub device (22) via a wire harness passing through the movable portion.

    摘要: A brake device includes: a battery connected to a power supply line; a fluid pressure unit driven by power from the supply line and applies fluid pressure to a brake; an alternator that receives power from a vehicle engine and generates power at a voltage higher than a charged voltage of the battery; a capacitor that stores the power generated by the alternator; and a DC/DC converter that converts the voltage of the capacitor to a predetermined value and supplies the converted voltage to the supply line. When the vehicle will potentially collide with a forward obstacle, an output of the DC/DC converter is set at a target higher than an output voltage in a normal state before brake actuation, or if output of the DC/DC converter cannot be set at the target voltage, the alternator is driven to connect a generation voltage of the alternator to the supply line.
