隨著資通訊之發展，交通運輸逐漸朝向聯網化，國際間各大車廠爭相投入自駕車之研發，期待創造更便利之次世代運輸方式。此外，於制度面各國亦先後開始制定相關規範，以盡速實現自駕車上路的目標。然而，在訂定相關規範時，除了車輛本身之硬體安全，因應車輛結合網路功能所可能帶來之資安威脅議題亦亟需正視，蓋不僅限於自駕車，任何可聯網之車輛皆可能暴露於網路安全的風險之下，故本文擬聚焦於自駕車之資安法制，並以日本2019年修正之《道路運輸車輛法》為核心，探討我國未來可能之修法方向。

With the growing development of information and communication technology, more and more transportation has been connected with the internet now. Major car manufacturers around the world are actively involved in the research and development of self-driving, hoping to create a more convenient next-generation transportation. In addition, in terms of regulations, many countries also have begun to formulate relevant regulations to achieve the goal of legalizing driving autonomous cars as soon as possible. However, when it comes to the statues of self-driving cars, in addition to the hardware safety of the vehicle itself, the possible threats of cyber security caused by the connection of vehicles with the internet are also needed to be solved urgently. It is not an issue that only happens to self-driving cars. Any connected vehicle may be exposed to the risk of cyber security. Therefore, this paper intends to focus on the cyber security statutes of self-driving cars, reviewing Road Transport Vehicle Act amended by Japan in 2019 to find the possible direction of law revision in Taiwan in the future.
