摘要： A plurality of semiconductor relays is provided between a power source and loads. The semiconductor relays have a function of a current detection for detecting a current passing through themselves. The loads are connected to output terminals respectively. A switching unit arbitrarily selects and switches a connecting destination of the semiconductor relays from among the plurality of output terminals. A microcomputer controls the switching unit on the basis of the detection results of a current flowing through the semiconductor relays, and adjusts the number of the semiconductor relays connected to the same load and connected to each other in parallel.

摘要： A load drive circuit shuts off power supply to a load when a semiconductor relay is off. The load drive circuit includes: the semiconductor relay which is turned off when a predetermined operation voltage cannot be secured; a low-voltage detection circuit which detects that the operation voltage is a predetermined value or less; a negative-voltage generation circuit which generates a negative voltage; and a switch unit which is turned on and connects between the negative-voltage generation circuit and a ground terminal of the semiconductor relay, in a case where the low-voltage detection circuit detects that the operation voltage is the predetermined value or less.

摘要： A vehicle load control device repeats a determination state in which at least one of a plurality of switching elements is turned off from an initial state in which the switching elements are all in an ON state until all of the switching elements have different ON/OFF states, and determines a connection form for each connection portion based on the change between an initial current value detected in the initial state and a determination current value detected for each determination state.

摘要： When an anomaly is determined in the transition of ECUs to a power saving state, a power supply control system sequentially turns on current supply switches while keeping a bypass switch on. A monitoring controller determines an anomaly in the transition of the ECUs to a power saving state on the basis of whether the dark current in the ECUs calculated from the amount of change at that time in the current in the power supply line is greater than an ordinary dark current. Further, in the startup state of the ECUs, power from a power supply can be supplied to the ECUs via the power supply line and individual supply lines.

摘要： When supplying electric power to a load from a power supply via a parallel circuit of two electrical wires having the same wiring resistance, a vehicular power supply control device uses a current measurement unit in intelligent power devices (IPDs) to measure a passing current flowing in a semiconductor switching device in each of the electrical wires. Then, in order to match the temperatures of the electrical wires as estimated by a present temperature estimation unit base on the measured current, a target duty ratio in a PWM control for reducing the passing current in the semiconductor switching device of the IPD on one electrical wire is calculated in a target duty ratio calculation unit, and the semiconductor switching device of the one IPD is turned on and off by a PWM/DC control and shutoff determination unit with the calculated target duty ratio.
