An electric power generation control system for a vehicle, which enables generation of electric power by a generator as much as possible while preventing an electrical component from being overheated by power generation by the generator. The electric power generation control system selectively switches a mode of the generator between first and second modes in which an instruction voltage is higher and not higher than an allowable voltage of a wire harness, respectively. A counter value is counted up in the first mode and down in the second mode. When the counter value has reached a higher limit value, the first mode is inhibited and the power generation mode is set to the second mode. This increase the proportion of an execution time period of the first, and accordingly, when a possibility of overheating the wire harness becomes high, the instruction voltage is lowered.

A power transfer device for connecting an electrical load to a power supply is disclosed. The power transfer device monitors the operating status of the power supply. Upon loss of power at the power supply, the power transfer device opens a switch between the power supply and the electrical load. When power is restored, the power transfer device executes a delay time module. After the delay time module has timed out, the power transfer device closes the switch to reconnect the power supply and the electrical load. Power transfer devices may be supplied to each of multiple loads connected to a power supply. By setting the time delay period of each power transfer device to a different duration, the electrical transients resulting from reconnecting all of the electrical loads to the power supply are reduced.

14	Determination of location of electrical disturbance	JP2013005866	2013-01-17	JP2013156247A	2013-08-15	ANDREW CERI DAVIS
PROBLEM TO BE SOLVED: To provide an apparatus and method for determining the location of an electrical disturbance in a circuit.SOLUTION: The relative phase of current and voltage waveforms across the circuit inductance of a portion of a circuit produced by a voltage or current perturbation is determined, and the location of an electrical disturbance within the circuit is identified based on the relative phase of the current and voltage waveforms. The relative phase of the current and voltage waveforms across the inductance of a portion of a circuit may be determined by calculating the sign (positive or negative) of the inductance of the portion of the circuit. The determination of the location of an electrical disturbance, for example within a particular distribution leg from among a plurality of distribution legs, enables just the leg affected by the electrical disturbance to be isolated, while a power source and the remaining portions of the circuit, such as various other loads or other components, are kept in operation.

PROBLEM TO BE SOLVED: To provide a power generation controller of a vehicle which can maximize power generation while preventing overheat of electrical components incident to power generation by a generator.SOLUTION: A power generation controller 1 of a vehicle switches the power generation mode of a generator 4 selectively between a first power generation mode where an instruction voltage VACG is larger than the allowable voltage VMAX of a wire harness 8, and a second power generation mode where an instruction voltage VACG is smaller than the allowable voltage VMAX. Furthermore, a counter value GCNT is counted up in the first power generation mode, and counted down in the second power generation mode. When the counter value GCNT reaches an upper limit NLMTH, the first power generation mode is prohibited, and the power generation mode is determined to be the second power generation mode. When the percentage of an execution period of the first power generation mode increases significantly and the risk of overheating the wire harness 8 is high, the instruction voltage VACG is lowered.
