What Does ADAS Mean?

on Thursday, 30 January 2020.

Everyone is talking about ADAS Systems in cars today and it’s a buzz acronym, but what does it actually mean? At Anderson Behel in Santa Clara, CA, we’re happy to provide some basic information about this new technology that will make us safer and more connected on the road.

Advanced driver-assistance systems (ADAS), are electronic systems that help the vehicle driver while driving or during parking. When designed with a safe human-machine interface, they are intended to increase car safety and more generally road safety. ADAS systems use electronic technology such as microcontroller units (MCU), electronic control units (ECU), and power semiconductor devices.

Most road accidents occur due to human error. Advanced driver-assistance systems are systems developed to automate, adapt and enhance vehicle systems for safety and better driving. The automated system which is provided by ADAS to the vehicle is proven to reduce road fatalities, by minimizing the human error. Safety features are designed to avoid collisions and accidents by offering technologies that alert the driver to potential problems, or to avoid collisions by implementing safeguards and taking over control of the vehicle. Adaptive features may automate lighting, provide adaptive cruise control and collision avoidance, pedestrian crash avoidance mitigation (PCAM), incorporate satnav/traffic warnings, alert driver to other cars or dangers, lane departure warning system, automatic lane centering, show what is in blind spots, or connect to smartphones for navigation instructions.

Modern vehicles today have advanced driver-assistance systems integrated to their electronics and manufacturers refresh their car models to add more of these features into their cars. Early advanced driver-assistance systems include electronic stability control, anti-lock brakes, lane departure warning, adaptive cruise control and traction control. These systems can be affected by mechanical alignment adjustments. This has led many manufacturers to require electronic resets for these systems, after a mechanical alignment is performed.

ADAS relies on inputs from multiple data sources, including automotive imaging, LiDAR, radar, image processing, computer vision, and in-car networking.[7] Additional inputs are possible from other sources separate from the primary vehicle platform, such as other vehicles, referred to as Vehicle-to-vehicle (V2V), or Vehicle-to-Infrastructure (V2X), such as mobile telephony or WiFi data network systems.

Advanced driver-assistance systems are one of the fastest-growing segments in automotive electronics,[8] with steadily increasing rates of adoption of industry-wide quality standards, in vehicular safety systems (ISO 26262), developing technology specific standards, such as IEEE 2020 for Image Sensor quality[9] and communications protocols such as the Vehicle Information API.[10]

Next-generation ADAS will increasingly leverage wireless network connectivity to offer improved value by using car-to-car (also known as Vehicle to Vehicle, or V2V) and car-to-infrastructure (also known as Vehicle to Infrastructure, or V2X) data.
