IPA IP 2022 Question 80
A question IPA Japan published in 令和4年度 ITパスポート試験 公開問題 問80, translated into English. ITPEC is based on the same exams.
Which of the following makes it possible to provide various information to the driver in real time by linking sensors and display devices mounted on a moving body such as an automobile with communication systems and information systems?
Explanation
Telematics — telecommunication plus informatics: services delivered to vehicles by linking their on-board devices with networks and information systems.
In telematics, sensors and displays mounted on a car or truck are connected over mobile networks to information systems, so the driver receives traffic and route information, accident and breakdown alerts or weather in real time, and the operator can track the vehicle's position and condition. Fleet management and usage-based car insurance are typical uses.
Answer (d)
Why not others:
- •(a) Actuator — a device that turns an electrical signal into physical motion, such as a motor or valve
- •(b) Carrier aggregation — a mobile communication technique that bundles several frequency bands (carriers) to raise the transmission speed
- •(c) Smart meter — an electricity (or gas, water) meter with a communication function that sends usage data to the utility
Key rule: Telematics means information services for moving bodies such as vehicles, built on mobile communication and on-board sensors.
