Porsche has filed a patent with the European Patent Office for a side-mirror base that integrates key hardware for its advanced driver-assistance system (ADAS). This includes a camera, a camera-cleaning system, and potentially additional sensors like parking sonar. By relocating this equipment from the mirror housing to the base, Porsche aims to achieve several advantages.
Why Porsche Wants to Move Sensors Out of the Mirror
To understand the significance of Porsche’s patent, it’s important to recognize the drawbacks of placing key equipment in the mirror housing. Components such as:
- Lamps
- Cameras
- Camera-cleaning systems
- Proximity sensors like parking sonar
are all affected by the movement of folding mirrors. This shifting position can interfere with sensor accuracy, reduce reliability, and force engineers to make design compromises. Since the mirror shell doesn’t remain fixed, cameras and other ADAS components may not always align correctly, impacting their performance.
Porsche’s Solution: A Stable, Pan-Like Mirror Base
Porsche’s solution is as simple as it’s elegant: relocate all sensors and equipment to the fixed mirror base. By mounting hardware on this stationary part of the vehicle, engineers eliminate issues caused by mirror movement. To accommodate the necessary components, the base is designed with a pan-like structure, providing ample space for cameras, sensors, and cleaning systems. The mirror itself remains functional, swiveling as usual without interfering with the integrated technology.
Key Advantages of Porsche’s Design
Porsche’s innovative mirror base design offers numerous benefits:
- Sensors and cameras, mounted on a fixed base, can be fine-tuned for better performance.
- Fewer wires and electrical components need to be routed through the mirror shell.
- Camera washer plumbing is no longer housed in the mirror, preventing interference with mirror folding.
- The design makes more efficient use of available space.
- It enables more compact, aerodynamic mirror housings.
- Expensive sensors are moved out of the vulnerable mirror shell, reducing replacement costs.
- Mirror replacement becomes significantly cheaper in the event of damage.
- ADAS hardware benefits from improved reliability and stability.
By relocating critical ADAS components to the mirror base, Porsche enhances functionality, reduces costs, and improves design efficiency—offering a smarter approach to integrating advanced vehicle technology.
