Automotive safety systems designed to avoid accidents are becoming increasingly common in today’s vehicles. New cars are often equipped with robust collision avoidance technologies due to regulations mandating their inclusion. These Active Safety technologies are enabled by innovative Advanced Driver Assistance Systems (ADAS) and use several sensor technologies, including radar, to detect conditions that may lead to a collision. With this, ADAS helps drivers arrive safely at their destination. Rogers is the world’s technology and market leader in innovative material solutions, providing high performance printed circuit board (PCB) laminates for automotive 24 GHz and 77 GHz radar sensor applications enabling active safety.
Radar-based ADAS systems are active safety systems that assist drivers by giving vehicles the virtual ability to sense the static and dynamic objects on the road. High frequency circuit materials from Rogers Corporation are critical to the reliability of radar sensors essential for ADAS. At RF and millimeter wave frequencies such as 24 and 77 GHz, radar sensor designers require thin core PCB laminates with low insertion loss and low dielectric constant. Rogers’ materials have an established reputation for excellent quality and reliability in the electrical and mechanical properties required for radar sensors to achieve the highest performance.
V2V is a crash avoidance technology which relies on communication of information between nearby vehicles to potentially warn drivers about dangerous situations that could lead to a crash. Seen as critical to the future of autonomous driving or self-driving cars, V2V can enable warnings that are not currently available to drivers through applications like Intersection Movement Assist, Left Turn Assist and Emergency Electronic Brake Light (EEBL). Reliable connectivity is essential for V2V systems and Rogers' high frequency materials used in antennas and modules are designed to achieve high performance and reliable connections between cars and infrastructure, even at high speed and under harsh vehicle environments.
With longer detection distance and the ability to “see” around corners or through other vehicles, V2X-equipped vehicles can perceive threats sooner than sensors, cameras, or radar can, and warn their drivers accordingly. With Vehicle-to-vehicle or vehicle-to-infrastructure communications, the car is communicating with other cars and nearby infrastructure by sending and receiving safety-related information through dedicated short range communication at 5.9 GHz (DSRC) or intelligent transportation system G5 (ITS-G5) and 3G/4G cellular network. Reliable connectivity is an essential requirement for DSRC and ITS-G5. Rogers’ high frequency materials are used in antennas and modules which are designed to achieve high performance and reliable connections between cars and infrastructure even at high speed and under harsh vehicle environments.
