解説
問 6
Incorrectア
Car sharing is a term for a service model in which multiple members reserve and jointly use a single car. It refers to a mode of usage, and does not represent a mechanism in which the vehicle exchanges information with a server over the internet and receives driving assistance.
Incorrectイ
A car navigation system is an in-vehicle device that determines the vehicle’s current position using GPS and the like, and guides the route to the destination on a map. Its main purpose is route guidance, and it is not a term for the whole mechanism of sending sensor information to a server and receiving two-way feedback to use for driving assistance.
- ウ
正解 A connected car is a term for a car that is equipped with a communication function to connect to the internet, sends information measured by in-vehicle sensors to a server, and can use the feedback from the server for purposes such as driving assistance. The question’s description — connecting to the internet, sending sensor information to a server, and receiving feedback from the server for driving assistance — matches this definition exactly, so ウ is the most appropriate.
Incorrectエ
An electric vehicle (EV) is a car that runs using an electric motor rather than gasoline as its power source, and is a term that classifies the power source. It is a different concept from the communication-function perspective of internet connectivity and information linkage with a server.
ここがポイント
- A connected car is a term for a car that is equipped with communication functions and stays constantly connected to an external server, thereby realizing driving assistance and various services through sending collected data and receiving feedback.
- The difference from the confusing options (car sharing = mode of usage, car navigation = route guidance, electric vehicle = power source) lies in the point of “two-way information linkage with a server via the internet.”
