차량 루프는 '비바람을 막는' 단순한 부품에서 '제3의 생활공간'의 인터랙티브한 인터페이스로 진화하고 있으며, 지능의 보급률은 지속적으로 증가하고 있습니다. 통계에 따르면 중국 승용차 시장에서 자동차 루프 인텔리전스 보급률은 2025년 24.9%를 보일 것으로 예측되며, 이는 2024년 대비 5.3% 증가한 것으로 시장 규모는 109억 위안에 달할 것으로 예측됩니다.
구체적으로 차량 루프의 지능화 방향으로는 고정형 파노라마 선루프, 천장 스크린, 루프 앰비언트 라이트, 프로젝션 스크린, 루프 디스플레이, 루프 태양광 발전, 루프 드론, 통합 센서 등을 들 수 있습니다.
고정형 파노라마 루프는 차체 상부에 장착되는 대형 유리 지붕으로, 자연광의 실내 유입, 넓은 시야각 제공, 개방감과 통풍성을 갖춘 공간 창출을 목적으로 설계되었습니다. 승차감, 차량 1대당 비용 등의 요인으로 인해 고정형 파노라마 선루프는 자동차 루프 인텔리전스 분야에서 가장 큰 응용 분야가 되었으며, 장착률은 2025년 20%를 넘어설 것으로 예측됩니다. 현 단계에서는 고정형 파노라마 선루프의 열복사 문제를 해결하기 위해 조광 필름이 최적의 솔루션이 되고 있습니다. 광 투과율을 조정하여 단열, 온도 감소 등의 효과를 얻을 수 있습니다. 예를 들어, SPD 필름과 PDLC 필름은 닫힌 상태에서 적외선을 90% 이상 차단하여 차량 내부 온도를 효과적으로 낮추고 에너지 소비를 줄일 수 있습니다.
천장 스크린은 장착률 2위이며, 조종석 내 '뒷좌석 엔터테인먼트' 컨셉으로 가장 빠르게 성장하는 제품입니다. 시장 규모는 2025년 9억 7,000만 위안에 달할 것으로 예측됩니다. 천장 스크린은 사용하지 않을 때는 접어서 지붕 안에 보관할 수 있어 실내 공간을 절약할 수 있습니다. 필요할 때는 스크린을 내려서 차내 영화관을 만들 수 있습니다. 현재 승용차 천장 스크린의 크기는 주로 15-31인치이며, LCD와 OLED가 주요 소재입니다.
카루프 프로젝션은 여러 대의 프로젝터와 이음매 없는 접합 기술을 통해 돔 구조를 프로젝션 스크린으로 변환하는 몰입형 비주얼 시스템입니다. 개폐식 선루프를 프로젝션 매체로 활용하는 것 외에도 AITO와 스텔라토(Stelato)가 발표한 지능형 프로젝션 시스템은 지붕에 승강식 스크린을 통합하여 영화 감상과 플로팅 윈도우 기능을 구현하고 있습니다.
카루프 앰비언트 라이트는 천장 부분에 간접 조명을 장착하여 차량 내부에 첨단 기술력과 시인성을 제공하는 조명입니다. 현재 크게 세 가지 기술 경로가 존재합니다. 첫째, 멀티 파이버 복합 조명(예: Maextro S800과 Rolls-Royce Wraith에 탑재된 별이 빛나는 지붕), 둘째, 백라이트 레이저 조각(예: BMW의 스타트랙 선루프), 셋째, 투명 가죽 기술(광투과 가죽 커버와 도광판 설계로 다양한 별이 빛나는 지붕 효과를 구현하고 판 설계를 통해 다양한 별이 빛나는 지붕 효과를 구현하고, 비용적인 우위를 가지고 있다).
태양광 발전 지붕은 태양광 발전 셀을 차량 루프에 통합하고, 태양광을 이용하여 발전하여 저전압 부하 및 배터리에 전력을 공급합니다. 이를 통해 차량 전체의 전력 소비를 줄이고 항속거리를 연장할 수 있습니다. 태양광 지붕의 가치는 두 가지 측면에서 발휘됩니다. 한편, 태양광 발전을 통한 직접 공급으로 에어컨 및 저전압 부하의 차량 전체 전력 소비를 5-8% 절감할 수 있습니다. 반면, 6평방미터의 지붕에서 하루 6-8kWh를 생산할 수 있다면 30-40km의 출퇴근 거리를 충당할 수 있고, 주 1회 충전 횟수를 줄일 수 있다는 계산이 나옵니다.
현재 차량용 태양광 발전의 기술 경로로는 헤테로 접합, 페로브스카이트 등이 주류를 이루고 있습니다. 이종접합 전지는 고효율과 안정성이 뛰어나지만, 제조비용이 높다는 단점이 있습니다. 반면, 페로브스카이트 전지는 제조비용이 저렴하고 광흡수 능력이 뛰어나지만 안정성이 떨어진다는 특징이 있습니다.
본 보고서는 중국의 자동차 산업을 조사 분석하여 차량 루프의 지능화, 고정형 파노라마 선루프의 특허, 차량 루프 공급업체와 제품 등의 정보를 제공합니다.
With the intelligent application of car roofs as the core, this report systematically sorts out a series of new products such as fixed panoramic sunroof/openable sunroof, ceiling screen, roof ambient light, projection screen, roof display, roof photovoltaic, roof UAV, integrated sensors, and special material roof.
The car roof is evolving from a single component for "shielding wind and rain" to an interactive interface of the "third living space", with the penetration rate of intelligence continuously rising. According to statistics, the penetration rate of automotive roof intelligence in China's passenger car market is expected to reach 24.9% in 2025, an increase of 5.3 percentage points compared with 2024, and the market size is expected to reach 10.9 billion yuan.
Specifically, the intelligent directions of car roof include fixed panoramic sunroof, ceiling screen, roof ambient light, projection screen, roof display, roof photovoltaic, roof UAV, integrated sensors, etc.
Fixed panoramic roof is a large glass roof located on the car roof. Its design purpose is to allow more natural light to enter the car, provide a broader field of view, and create an open and ventilated sense of space. Driven by factors such as riding experience and single-vehicle cost, fixed panoramic sunroof has become the largest application area of car roof intelligence, with an installation rate exceeding 20% in 2025. At this stage, aiming at the thermal radiation problem of fixed panoramic sunroof, dimming film has become the best solution. By adjusting light transmittance, it achieves effects such as heat insulation and temperature reduction. For example, SPD and PDLC films can block more than 90% of infrared radiation in the closed state, effectively reducing the temperature inside the car and cutting energy consumption.
Ceiling screen ranks second in installation rate and is the fastest-growing product under the concept of "second-row entertainment" in the cockpit. Its market size will reach 970 million yuan in 2025. The ceiling screen can be hidden in the roof by folding when not in use to save interior space; when needed, the screen can be lowered to create an in-car cinema. At present, the size of ceiling screens in passenger cars is mostly between 15-31 inches, with LCD and OLED as the main materials.
Car roof projection is an immersive visual system that converts the dome structure into a projection screen through multiple projectors and seamless splicing technology. In addition to using the openable sunroof as a projection carrier, the intelligent projection systems launched by AITO and Stelato integrate a liftable projection screen on the roof to realize movie viewing and floating window functions.
Car roof ambient light refers to installing ambient lights in the ceiling area to bring higher technology and visibility to the car interior. Currently, there are three main technical paths: first, multi-fiber combined lighting, such as the starry sky roof equipped on Maextro S800 and Rolls-Royce Wraith; second, backlight laser engraving, such as BMW's star track sunroof; third, transparent leather technology, which achieves different starry sky roof effects through light-transmitting leather covering and light guide plate design, with cost advantages.
The photovoltaic roof integrates photovoltaic cells into the car roof, using sunlight to generate electricity to provide energy for low-voltage loads and power batteries, reducing the overall vehicle power consumption and extending the driving range. The value of photovoltaic roof is reflected in two aspects: on the one hand, photovoltaic direct supply can reduce the overall vehicle power consumption of air conditioning and low-voltage loads by 5-8%; on the other hand, for car owners, a 6 m2 roof that generates 6-8kWh/day can support 30-40 km of commuting, which is equivalent to charging once less per week.
Currently, technical routes of in-vehicle photovoltaics mainly include heterojunction, perovskite, etc. Heterojunction batteries have high efficiency and good stability but high manufacturing costs; perovskite batteries have low manufacturing costs and strong light absorption capacity but poor stability.
Heterojunction (HJT) batteries have the characteristics of high conversion efficiency (mass production efficiency above 24%), low attenuation rate (<0.25%/year), and low temperature coefficient (-0.25%/°C). At present, one of the factors restricting the large-scale mass production of heterojunction batteries is their cost. With the improvement of technology, heterojunction batteries that successfully reduce costs are expected to become mainstream. Currently, BYD has mass-produced and installed them on vehicles, and enterprises such as Huasun also have relevant layouts.
BYD's heterojunction battery mass-produced in 2025 has a photoelectric conversion efficiency of 23.18%. The first models to be equipped with it are hybrid models such as the 2025 Han DM-i and Qin PLUS DM-i, with an optional price of 8,000 yuan. In addition, BYD plans to increase its production capacity to 1 million sets in 2026, and its future goal is to cover 6m2 curved surfaces such as car roof, engine hood, and doors, with power rushing to 2,000 watts to achieve "no charging for a week".
In June 2025, Huasun launched an automotive photovoltaic product equipped with heterojunction curved modules, adopting an integrated curved glass and 0BB module design. It has both aesthetics and efficient power generation performance, fits the body curve better, and adapts to complex road conditions and rural travel scenarios. The product can generate more than 1.2 kWh of electricity per day, bringing an increase of about 25km in driving range, and the annual power generation can meet the travel demand of 2,000km.
Perovskite has higher theoretical efficiency and lower cost. Moreover, due to its characteristics of being thin, light, bendable, and can be made transparent or colored, it is expected to cover the entire body surface in the future to realize vehicle-wide power generation, and is regarded as the key to the next generation of in-vehicle photovoltaics. At present, there have been practical explorations in the field of new energy vehicles, and the main layout players include Changan, BYD, Toyota, Great Wall Motor, BOE, Rollshine Photoelectric, etc.
At the 2025 AI Expo, Changan Automobile launched a new transparent photovoltaic body technology, which is equipped on the Avatr 07. The photovoltaic battery adopts a new material and structural design, realizing the power generation function while ensuring light transmittance. It is claimed that it can provide 10,000 kilometers of power a year, with a power of 500-1000 watts and an increase of 20 kilometers in daily driving range, which can cover daily commuting.
Changan Automobile adopts a new type of photovoltaic battery with "tunable bandgap" and "ultra-thin tandem" characteristics. In March 2025, Deepal (a subsidiary of Changan) applied for a patent for "metal halide perovskite nanocrystal film", showing an active layout in the next generation of photovoltaic technology.
In June 2025, BOE released the perovskite CIPV (Car Integrated Photovoltaic) dimmable glass sunroof. It applies flexible perovskite power generation technology, realizing dynamic color change of the roof through solar energy self-driving, and adaptively adjusting the brightness inside the car in scorching sun and rainy environments. This product is a large-size automotive glass roof integrating perovskite solar cells and intelligent dimming function.
Car roof UAV integrates UAV take-off and landing platform, power supply, communication and temperature control system on the roof, making the vehicle a mobile airport, realizing UAV take-off, landing, charging and data transmission along with the vehicle.
Currently, automakers mainly carry out in-depth cooperation with UAV manufacturers. By building hangars and parking aprons on car roof and deeply coupling with the IVI, dynamic take-off & landing and automatic charging are realized. The main layout companies include BYD, Dongfeng, etc.
BYD "Lingyuan" In-Vehicle UAV System
In March 2025, BYD officially released the world's first mass-produced roof-mounted UAV system "Lingyuan", which adopts an integrated design of intelligent hangar, integrating a UAV take-off and landing platform on the roof, and is equipped with in-vehicle positioning module, vehicle-grade anemometer, image transmission antenna, roof camera and intelligent temperature control system. The "Lingyuan" system supports functions such as dynamic take-off and landing, one-key return, and precise landing, and can automatically complete charging. It covers brands such as Yangwang, BYD Dynasty, Ocean, Denza, and Fangchengbao, becoming the world's first vehicle-grade mass-produced solution.
Dongfeng "Tianying" In-Vehicle UAV System
In April 2025, Dongfeng M-HERO was equipped with the "Tianying" intelligent in-vehicle UAV system developed by GDU Tech. The "Tianying" system is composed of five modules including the professional-grade S180 UAV and the K05 detachable in-vehicle hangar. It is compatible with various models such as sedans, SUVs, MPVs, and off-road vehicles, without modifying the original vehicle, and can be loaded and unloaded within 3 minutes. The system is equipped with a 48MP gimbal camera, supports a wide-angle + telephoto dual-camera combination, and has 4K full-color starlight night vision and infrared thermal imaging functions. It can be applied to various scenarios such as aerial photography, advance route exploration, and emergency rescue.
