The headline might sound strange, but here’s an explanation. Honda has submitted documents to patent a new system of passive radar reflectors that will make motorcycles more visible and recognizable by the radar systems of other vehicles – somewhat similar to what happens with boats.
This new system will make motorcycles more visible to vehicles equipped with technologies such as blind spot detection or adaptive cruise control. The radar systems in both motorcycles and cars monitor the position of other vehicles and objects on the road to enable aids like those mentioned, including anti-collision systems or even auto braking, among others.
However, due to their size, motorcycles are harder to detect. This is where Honda’s patented solution comes in: it uses passive radar reflectors, widely used in boats since World War II. Other manufacturers are working on similar solutions, with BMW and Suzuki also submitting patents.
The system consists of several bowl-shaped reflectors made of reflective plates. Radar waves are reflected back, amplifying the signal and improving vehicle detection. These are positioned behind the windshield, without affecting the overall design or aerodynamics. Being made from metal or plastic, they are cost-effective components.
While this is still in the patent phase, and it’s uncertain if or when it will reach production models, it remains an interesting concept that could enhance motorcyclist safety.
