Development and mass production of the new peripheral monitoring radar “MMR2”

A new 24GHz (ISM band) peripheral monitoring radar “MMR2” was developed, and mass production has started. This new radar was developed using model-based design (MBD) in which development and verification proceeded simultaneously. It conforms to the ISO26262 international standard for vehicle functional safety and ISO/SAE 21434 international standard for vehicle cybersecurity. Currently, it has been adopted for use in the new Mazda CX-60 crossover SUV announced in Japan in April this year.
Because the MMR2 has improved conformance for the NCAP and new applications, it offers a broader range of detection than previous models, and both speed detection accuracy and spatial recognition performance were increased. Radar units are envisioned to be installed in the four corners of the vehicle, enabling a broad range of detection applications, including head-on collisions, when turning right or left at an intersection, when changing lanes, when the vehicle is stopped and general driving conditions. The volume and weight of the radar unit have been reduced by about 30%, making installation on the inside face of the bumper possible.
Our 24GHz peripheral monitoring radar has excellent features including low transmission loss when passing through the bumper and a small size that minimizes the impact on vehicle design and material considerations. Also, because the radar is not significantly affected by rain, snow or dirt, it offers solid performance in all weather conditions.

Furukawa AS will continue to advance the development of peripheral monitoring radar applications, promote the use of peripheral monitoring radar in a wide range of vehicles including automobiles and contribute to creating a safer society through the further application of this technology.
