Abstract: A flat wiring structure is including a plurality of layers, and includes a power supply layer, and a first ground layer and a second ground layer laminated with the power supply layer sandwiched therebetween. In a plan view of the flat wiring structure when viewed from a direction along a lamination direction of the first ground layer, the power supply layer, and the second ground layer, the power supply layer has a width in a short direction smaller than those of the first ground layer and the second ground layer, and the power supply layer is provided at a position covered with the first ground layer and the second ground layer.

Abstract: A vehicle power generating device includes an alternator which has a voltage regulator that keeps the voltage of generated power constant, and an electronic control unit that controls the voltage regulator. In this vehicle power generating device, the alternator has an abnormally high temperature determining portion that determines whether the temperature of the alternator is abnormally high, and an abnormal signal outputting portion which, when it has been determined by the abnormally high temperature determining portion that the temperature of the alternator is abnormally high, outputs a signal indicative of the determination that the temperature is abnormally high to the electronic control unit. Also, when the electronic control unit receives the signal indicative of the determination that the temperature is abnormally high, the electronic control unit controls the voltage regulator such that the voltage generated by the alternator is suppressed.
