In an on-vehicle power control system in which a power supply and a power distribution device that distributes power supplied from the power supply to a load are connected by a power supply trunk line, and in an on-vehicle power network to which a plurality of the power distribution devices are connected by the power supply trunk line is configured, the power distribution device includes: a semiconductor switch configured to switch a power supply trunk line path to another power supply trunk line path when a failure occurs in the power supply trunk line path through which power is supplied from the power supply trunk line to the own device, and distribute power supplied from the switched power supply trunk line path to the load; and a control unit configured to, when a failure occurs in the power supply trunk line path, bring the semiconductor switch into an intermediate state in which the semiconductor switch is held in an unsaturated state based on switch characteristic information at a timing of switching the power supply trunk line path to the another power supply trunk line path, and perform switching control on the semiconductor switch such that a current flowing into the load from the semiconductor switch in the intermediate state becomes less than an allowable current.
An on-vehicle power control system in which a power supply and a power distribution device that distributes power supplied from the power supply to a load are connected by a power supply trunk line, and power to be supplied to the power distribution device is controlled in an on-vehicle power network to which a plurality of the power distribution devices are connected by the power supply trunk line, wherein
A power distribution device connected to an on-vehicle power network, to which a plurality of power supplies are connected, by a power supply trunk line to distribute power to a load, the power distribution device comprising:
A vehicle central control device provided in an on-vehicle power control system in which a power supply and a power distribution device that distributes power supplied from the power supply to a load are connected by a power supply trunk line, and power to be supplied to the power distribution device is controlled in an on-vehicle power network to which a plurality of the power distribution devices are connected by the power supply trunk line, wherein
