Rivian 公佈新 AI 晶片及 2026 年 R2 電動車頂置激光雷達

美國電動車製造商 Rivian 最近於加州帕洛阿爾托總部舉行「Autonomy & AI」活動,展示其下一代駕駛輔助技術及未來自動駕駛功能的發展藍圖。Rivian 亦透露將於明年推出新一代 Rivian Assistant 語音助理,為現有及未來的 R1 和 R2 電動車提供智能互動體驗。作為行業內重要一員,Rivian 的硬件及軟件升級預計將大幅提升旗下車型的自動駕駛能力及用戶便利性。

Rivian 新核心:RAP1 AI 晶片與第三代自動駕駛電腦

Rivian 推出的首款自家研發 AI 晶片「Rivian Autonomy Processor」(RAP1),是一款多晶片模組,將處理器與記憶體集成,專為人工智能及自動駕駛數據運算而設計。未來 R2 電動 SUV 將配備兩個 RAP1 晶片組成的第三代自動駕駛電腦(Gen 3 Autonomy Computer),效能較現有第二代系統提升四倍,能每秒處理約 50 億像素的感應器數據。新系統能效提升 2.5 倍,對續航影響不大,但每瓦節省對電動車來說都是寶貴。

R2 配備全新車頂激光雷達及升級感應器組合

Rivian R2 電動車將首次搭載隱藏於擋風玻璃上方車頂線條內的激光雷達陣列,設計避免了傳統「的士頂燈」突起,令車身外觀更流暢。配合升級後的 11 個高解像度攝像頭,總像素達 6500 萬,提升車輛的視覺感知能力。此外,五個重新設計的雷達單元令短距離偵測更準確,Rivian 更大膽取消了超聲波泊車感應器,顯示對新雷達技術的信心。

自動駕駛藍圖:從免手持到全自動 L4 級別

Rivian 正在開發名為「Large Driving Model」的大容量 AI 模型,利用類似大型語言模型的神經網絡技術,應對複雜的真實駕駛場景。該技術將於 2026 年初在現有 R1 車主推出的 Autonomy Plus 套件中應用,覆蓋美加約 350 萬英里道路,支援高速公路及清晰車道線的非高速公路免手持駕駛。用戶可選擇一次性付費 2500 美元或每月 50 美元試用。未來,R2 車型將實現點對點免手持駕駛,並逐步推進至免視線監控,最終達到定義條件下的 L4 級自動駕駛。

Rivian Assistant:全新 AI 語音助理提升車內互動

除了自動駕駛,Rivian 亦展示其新 AI 硬件如何提升車內便利性。Rivian Assistant 是一款支援在線及離線的智能語音助理,能理解自然語言,並與車載應用程式及服務緊密整合。現場示範中,助理成功調用用戶的 Google 日曆安排,實時更改會議時間,再透過語音搜尋附近餐廳,將最佳選項發送給會議參與者,並提供更新抵達時間。該助理將於明年初登陸第一及第二代 R1T 和 R1S 車型,並於 2026 年底隨 R2 車型原生推出。

評論與啟示

Rivian 今次的技術發佈標誌著其在電動車自動駕駛領域的積極布局,尤其是自家研發 AI 晶片和整合激光雷達技術,顯示出對提升感知能力和運算效能的決心。相比只依賴相機和雷達的方案,激光雷達在精確度和短距離感知方面有明顯優勢,對於複雜路況下的安全保障至關重要。取消超聲波感應器這一大膽做法,也反映出其對新感應技術的信心。

此外,Rivian 採用類大型語言模型的 AI 方式來處理駕駛決策,突破了傳統自動駕駛系統的限制,這種跨界應用值得業界關注。Autonomy Plus 的定價策略亦平衡了用戶接受度與技術推廣,為未來普及自動駕駛鋪路。

在語音助理方面,Rivian Assistant 的自然語言理解及與生活應用深度結合,將為用戶帶來更順暢的車內互動體驗。這不僅提升駕駛便利性,更有助於打造差異化的品牌形象。

總結來說,Rivian 的技術更新不僅是硬件升級,更是智能汽車生態系統的構建。對香港市場而言,隨著本地智能交通和電動車普及,類似這樣融合 AI 與感應技術的電動車將成為未來趨勢,值得用戶和業界密切關注。

Create a hyper-realistic 8K close-up body portrait of a female model, using the uploaded photo as the exact facial reference. Maintain 100% accuracy of the facial features — do not alter or modify any aspect of the face. Render the skin texture, lighting, and overall composition with photo-realistic detail, ensuring lifelike color tones and natural depth of field. A man with his original hair is sitting casually on a white cube, smiling warmly at the camera. He is wearing a cream-colored cable-knit sweater, blue jeans, and brown loafers. His legs are crossed, with one hand resting on his knee.
The background reveals a cozy and festive living room. A large, beautifully decorated Christmas tree with numerous warm lights and gold ornaments stands prominently behind him. Several wrapped gift boxes are visible at the base of the tree. To his left, another smaller decorated Christmas tree and a wreath on the wall further enhance the holiday atmosphere. The lighting is soft and inviting, creating a warm and welcoming scene. add hello kitty Generate an ultra-realistic, highly ultra-detailed, 8k resolution with 1080x1080 pixel portrait of me using the uploaded image for reference (preserved the likeness and the original face for reference) of a striking, high-resolution portrait of a young woman with long, flowing wavy brunette hair, seated gracefully on a simple black wooden chair in a dimly lit studio. She wears an oversized, off-white knitted sweater that drapes loosely over her frame, slipping off one shoulder to reveal smooth skin and add a subtle touch of sensuality. Her pose is elegant and contemplative: one arm rests gently on the chair’s backrest while her hand delicately supports her chin, and her gaze is directed thoughtfully toward the side, creating an intimate and introspective mood. The lighting is expertly crafted with a single soft, directional light source positioned to the side, casting gentle shadows that sculpt her form and highlight the texture of the knitwear and the natural contours of her legs and arms. This chiaroscuro effect enhances the depth and dimensionality of the image, emphasizing the softness of her skin and the intricate weave of the sweater. The background is a smooth, muted dark gray, providing a minimalist and distraction-free backdrop that contrasts beautifully with her light-colored apparel and warm skin tones. *** The composition is a full-body vertical frame that captures the model’s seated posture with perfect balance, positioning her slightly off-center to create visual interest and harmony. The overall color palette is subdued and warm, featuring neutral tones that evoke a sense of calm and understated elegance. The image is impeccably sharp, showcasing fine details such as the delicate waves of her hair, the subtle folds in the fabric, and the natural texture of her skin. The style is classic and timeless, blending modern minimalism with emotive portraiture to convey quiet strength, beauty, and introspection.
