TDAx ADAS SoCs – Driver monitoring

A camera-based Driver Monitoring System (DMS) or in-vehicle monitoring system is an emerging function that observes the driver, and possibly other occupants, to better enable safety and/or convenient features of a vehicle.  DMS solutions can detect and track eye movements, head position, and various focal points of a driver's face to determine the state of the driver.  Basic driver states interpreted can be driver presence, vigilance, fatigue, and distraction.  More advanced interpreted states are ranges of emotions, specific driver identification and biological details, e.g. age, gender, illness, etc.  As with many automotive systems, there are a broad range of capabilities enabled by these DMS implementations within any one OEM and throughout the overall market.

Basic Driver Monitoring Systems are comprised of an interior camera pointed at the driver's face and infrared LEDs generating imperceptible beams of light to produce facial images that can be captured in low light conditions.  Analytics are performed on the captured images to interpret the states. More advanced systems can include multiple sensor inputs such as several cameras, various radars and/or other sensor types.

TI’s Jacinto TDAx automotive processors are designed to address the key care-abouts of Driver Monitoring Systems such as safety, convenience and autonomous-supporting features. In addition, TI provides complete hardware and software scalability enabling easy development of optimized solutions and faster time to market.

TI works with multiple 3rd party companies to offer scalable solutions to address the forecasted evolution of Driver Monitoring Systems.
