Abstract: An electronic control unit includes: a nonvolatile memory capable of erasing data in units of erasure blocks and also writing data in units of write blocks smaller than the erasure blocks; and a processor. In response to a data rewrite request from outside, the processor of the electronic control unit erases data in a portion of the nonvolatile memory in units of erasure blocks and writes data into the portion of the nonvolatile memory in units of write blocks. The amount of data sent to the electronic control unit from outside is thereby decreased and the time needed to rewrite data in the nonvolatile memory is reduced.

Abstract: A power converter with a simple configuration capable of controlling a rush current is provided. The power converter is installed between an electric power system and a power storage device, includes a harmonic filter in an AC circuit on the electric power system side and a DC capacitor and a DC breaker in a DC circuit on the power storage device side, and performs AC/DC conversion processing using an inverter. The power converter is configured in such a way that, when the power storage device starts running, a current limited by a limiting resistor is given from the electric power system side to the DC capacitor, the difference between the voltage of the DC capacitor and the voltage of the power storage device is monitored, and the power converter is connected to the power storage device by switching on the DC breaker on the basis of the difference.

Abstract: A physical quantity measuring device includes: a sensor module provided with a diaphragm; a joint to which the sensor module is attached, the joint including a pressure inlet for delivering fluid to be measured to the sensor module. The joint is made of a synthetic resin and includes a joint body and an elastically deformable claw provided to the joint body and configured to lock the sensor module. Since the claw keeps the sensor module to be held by virtue of the elastic force of the claw, a further attachment process such as welding for attaching the sensor module to the joint is unnecessary. Since the joint body and the claw are integrally made of synthetic resin, it is not necessary to separately manufacture the joint body and the claw.

Abstract: An automotive electronic control unit receives rewrite data wirelessly transmitted in units of a predetermined size from an external device and rewrites data stored in a nonvolatile memory based on the rewrite data. At this time, the rewrite data is communicated by switching between broadcast communication and unicast communication, or between multicast communication and unicast communication.
