汽车固定式全景天窗和智慧车顶(2025)Automotive Fixed Panoramic Sunroof and Smart Roof Research Report, 2025 |
||||||
汽车车顶正从简单的遮风挡雨部件演变为 "第三个生活空间" 的互动介面,智慧车顶的渗透率持续成长。根据统计,到2025年,中国乘用车智慧车顶的渗透率将达到24.9%,比2024年成长5.3个百分点,市场规模预计将达到109亿元。
智慧车顶的具体发展趋势包括:固定式全景天窗、车顶萤幕、车顶气氛灯、投影萤幕、车顶显示器、车顶太阳能发电系统、车顶无人机以及整合感测器。
固定式全景天窗是指安装在车辆顶部的大型玻璃车顶。它们旨在让自然光进入车内,提供宽广的视角,并营造开放通风的空间。由于乘客体验和单车成本等因素,固定式全景天窗已成为汽车车顶智慧化的最大应用领域,预计到2025年,其安装率将超过20%。目前,光控膜是解决固定式全景天窗热辐射问题的最佳方案。透过调节透光率,它们可以实现隔热降温效果。例如,SPD和PDLC薄膜在关闭时可阻挡90%以上的红外线辐射,有效降低车内温度和能耗。
就安装率而言,天窗是第二大最受欢迎的产品,也是驾驶舱 "后排娱乐" 概念下成长最快的产品。预计2025年,其市场规模将达到9.7亿元。天窗在不使用时可以折迭并收纳在车顶内,从而节省车内空间。需要时,它可以降下,打造车内戏院。目前,乘用车车顶萤幕尺寸通常为 15-31 英寸,主要采用 LCD 或 OLED 材质。
车顶投影是一种沉浸式视觉系统,它利用多个投影机和无缝粘合技术,将穹顶结构转化为投影萤幕。除了使用可伸缩天窗作为投影介质外,AITO 和 Stelato 等公司发布的智慧投影系统还将可伸缩萤幕整合到车顶,从而实现观影和悬浮窗功能。
车顶环境照明系统在车顶区域采用间接照明,为车内带来先进的技术和良好的可视性。目前,主要有三种技术方案。第一种是多纤维复合照明(例如 Maextro S800 和劳斯莱斯 Wraith 上的星空顶);第二种是背光雷射雕刻(例如BMW的星空顶);第三,透明皮革技术(透光皮革覆盖层和导光板设计可实现多种星空顶效果,同时具有成本优势)。
太阳能车顶将太阳能电池整合到车顶,利用阳光发电,为低压负载和电池供电。这降低了车辆的整体能耗,并延长了续航里程。太阳能车顶的价值体现在两个方面。首先,直接太阳能发电可降低车辆空调和低压负载的整体能耗5-8%。其次,如果一个6平方公尺的车顶每天能产生6-8千瓦时的电量,即可满足30-40公里的通勤需求,减少车辆每週充电的次数。
目前,异质结和钙钛矿技术是车载太阳能发电的主流技术。异质结电池效率高、稳定性好,但製造成本高。钙钛矿电池则製造成本低、光吸收能力强,但稳定性较差。
本报告调查分析了中国汽车产业,提供了有关智慧车顶、固定式全景天窗专利、车顶供应商和产品的资讯。
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.
