Provided are a rewriting system capable of shortening rewrite time, a rewriting system and a computer used for the rewriting system. The rewriting system includes an ECU and a rewriting device for at least transmitting to the ECU a rewrite data of memory contents stored in a flash ROMB (memory), the flash ROMB (memory) includes a rewrite target area Ain which the memory contents to be rewritten are stored and a non-rewrite target area Ain which the memory contents not to be rewritten are stored, and the rewriting device transmits the rewrite data of the memory contents to the ECU only for the memory contents of the rewrite target area in the flash ROMB (memory).

Rewriting system, rewriting device and computer

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.

Load controller and load control method

An ID setting device includes: an output circuit configured to output, as serial data, an ID to be set in an ECU, which is an ID setting target; an input circuit to which an ID that is set is input as serial data from the ECU; and a control unit configured to check the ID output by the output circuit and the ID input to the input circuit against each other. The serial data has a duty cycle which is according to setting data on a per bit basis.

Information setting device and electronic appliance

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.

Power supply control system

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.
