Texas Instruments (TI) offers new automotive driver assistance systems (ADAS) chip


Wednesday, January 12, 2022

Texas Instruments (TI) has significantly expanded its automotive offerings that can help automakers improve how advanced driver assistance systems (ADAS) sense objects.

TI’s AWR2944 radar sensor adds to the company’s extensive portfolio and increases the ability to quickly detect objects, monitor blind spots, and efficiently navigate turns and corners.

“Changing lanes and navigating tight corners present some of the most complex design challenges for our customers today,” said Yariv Raveh, manager for TI millimeter-wave radar. “To create a safer driving experience, driver assistance systems must quickly and accurately process massive amounts of data and clearly communicate with the driver.”

The 77-GHz AWR2944 radar sensor has been developed to help automakers meet new safety regulations and comes in a very small form factor – approximately 30% smaller when compared to many other radar sensors, according to TI. The sensor integrates a fourth transmitter to provide higher resolution, enabling vehicles to detect obstacles more clearly and avoid collisions. In addition, the new sensor’s hardware is supported by Doppler division multiple access (DDMA)-based signal processing which improves the ability to sense oncoming vehicles at distances up to 40% farther away.

“Visibility around corners has historically been challenging for autonomous and semi-autonomous vehicles. This challenge presents the opportunity to design high-quality, premium ADAS technology that helps enhance vehicle perception,” said Curt Moore, manager for Jacinto processors at TI. “For automated parking and driving, being able to see farther with devices like the AWR2944 sensor leads to improved awareness and safety.”
