解説
問 80
Incorrectア
An actuator is a driving device that converts input such as electrical signals into physical motion like rotation or movement. It is a component that moves a controlled object, not a mechanism that provides information to drivers.
Incorrectイ
Carrier aggregation is a technology that bundles multiple frequency bands (carriers) and uses them simultaneously to speed up mobile communication. It is a measure to improve communication speed, not the mechanism itself that provides information about the moving object to drivers.
Incorrectウ
A smart meter is a metering device with communication functions that remotely measures and transmits usage of electricity, gas, and the like. It is a device for energy management, not for providing information to automobile drivers.
- エ
正解 Telematics is a coined word combining telecommunication and informatics. It refers to a mechanism that links sensors and display devices installed in moving objects such as automobiles with communication systems and information systems, providing drivers with information such as traffic congestion, routes, and vehicle status in real time. The statement in the question matches this definition exactly, so the correct answer is “エ”.
ここがポイント
- Definition of telematics: a coined word from telecommunication + informatics, referring to a mechanism that links in-vehicle sensors and devices with communication/information systems to deliver real-time information to drivers.
- Distinguish the difference in role from confusing terms: actuator = driving device, carrier aggregation = communication speed-up, smart meter = remote metering device.
