TI introduces sensor to monitor blind spots and navigate turns in cars

04 January 2022

Texas Instruments (TI) has unveiled at CES 2022 a new automotive sensor to improve how advanced driver assistance systems (ADAS) sense objects.

The AWR2944 is a radar sensor that can detect objects, monitor blind spots and navigate turns and corners. TI said the radar sensor can help automakers meet safety regulations and radio frequency performance in one chip that is about 30% smaller than current radar sensors.

The sensor integrates a fourth transmitter for 33% higher resolution compared to existing solutions, allowing vehicles to detect obstacles more clearly and to avoid collisions, TI said. The 77 GHz sensor also is supported by Doppler division multiple access (DDMA)-based signal processing to improve the ability of vehicles to sense objects at distances up to 40% farther away.

“Changing lanes and navigating tight corners present some of the most complex design challenges for our customers today,” said Yariv Raveh, manager for millimeter-wave radar at TI. “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 sensor adds to TI’s portfolio of ADAS solutions that include:

  • Integrated system-on-chip radar sensors
  • Artificial intelligence processors
  • Power management ICs
