車輛動力與底盤線控化技術 2022/07/12

簡介 Introductions

因應國際車輛智能自駕趨勢，車輛自駕化及線控化需求遽增。工研院機械所已建立完整的車輛動力與底盤線控化技術，包含線控動力 (throttle-by-wire)、線控排檔 (shift-by-wire)、線控轉向 (steer-by-wire) 及線控煞車 (brake-by-wire)技術，並具備多家車廠貨卡車以及巴士等車型線控化技術服務實績，搭配工研院之車輛自駕技術，協助業者獲得政府之智能自駕運行計畫。

As the intelligent automated driving trend in global automotive industries, the demands for automated and X-by-wire technologies increase dramatically. ITRI has established comprehensive powertrain and chassis by-wire technologies that include throttle-by-wire, shift-by-wire, steer-by-wire and brake-by-wire. With ITRI’s satisfactory technical services to several automotive OEMs, the automated and X-by-wire technologies have been implemented in several vehicles and have helped those OEMs to get government’s intelligent automated driving pilot projects.
