Some advanced driver-assistance systems (ADAS) have been available for nearly 30 years. However, some of them – such automatic emergency braking and lane-keeping assistance – are relatively new.
Since these features now come standard on many new vehicles, it’s becoming increasingly important for consumers to have a solid understanding of their functionality, AAA says. However, with the current variety of marketing names and lack of consensus by industry regulatory groups, it has been difficult for consumers to discern what features a vehicle has and how they actually work.
AAA set out to understand the growing prevalence of ADAS technology in new vehicles as well as examine the terminology currently used by regulatory organizations and manufacturers. Previous AAA research found that 40 percent of Americans expect partially automated driving systems with names such as Autopilot, ProPILOT or Pilot Assist to have the ability to drive the car by itself.
AAA’s research highlights the need for standardization of terms and definitions for ADAS features, the organization says.
Cost/Prevalence of ADAS Technology
AAA examined 2018 model-year vehicles to identify the percentage of ADAS technology that comes standard and found the following three features are the most prevalent:
- Automatic emergency braking – 30.6 percent
- Lane-keeping assistance – 13.9 percent
- Adaptive cruise control – 11.8 percent
Multiple ADAS features often are sold as part of an optional technology bundle. On average, the cost of an ADAS bundle is approximately $1,950.
As of May 2018, at least one ADAS feature is available in 92.7 percent of new vehicle models available in the United States, according to AAA.
AAA’s Automotive Engineering team examined 34 vehicle brands sold in the United States to identify the number of unique names manufacturers use to market ADAS. AAA found the following regarding the number of terms used to describe a single ADAS feature:
|ADAS Feature||Number of Unique Names|
|Automatic emergency braking||40|
|Adaptive cruise control||20|
|Automatic high beams||18|
|Rear cross-traffic warning||15|
|Semi-automated parking assist||12|
|Forward collision warning||8|
|Night vision and pedestrian detection||5|
Proposed Terminology for ADAS
AAA is proposing terminology that is intended to be simple, specific and based on system functionality.
Automated Driving Tasks
- Adaptive cruise control – Controls acceleration and/or braking to maintain a prescribed distance between it and a vehicle in front. May be able to come to a stop and continue.
- Dynamic driving assistance – Controls vehicle acceleration, braking, and steering. SAE standard definition of L2 Autonomous systems outlines this functionality.
- Lane-keeping assistance – Controls steering to maintain vehicle within driving lane. May prevent vehicle from departing lane or continually center vehicle.
- Blind-spot warning – Detects vehicles to rear in adjacent lanes while driving and alerts driver to their presence.
- Forward collision warning – Detects impending collision while traveling forward and alerts driver.
- Lane-departure warning – Monitors vehicle’s position within driving lane and alerts driver as the vehicle approaches or crosses lane markers.
- Parking-obstruction warning – Detects obstructions in close proximity to vehicle during parking maneuvers.
- Pedestrian detection – Detects pedestrians in front of vehicle and alerts driver to their presence.
- Rear cross-traffic warning – Detects vehicles approaching from side and rear of vehicles while traveling in reverse and alerts driver.
- Automatic emergency steering – Detects potential collision and automatically controls steering to avoid or lessen the severity of impact.
- Forward automatic emergency braking – Detects potential collisions while traveling forward and automatically applies brakes to avoid or lessen the severity of impact.
- Reverse automatic emergency braking – Detects potential collision while traveling in reverse and automatically applies brakes to avoid or lessen the severity of impact.
- Fully automated parking assistance – Controls acceleration, braking, steering, and shifting during parking. May be capable of parallel and / or perpendicular parking.
- Remote parking – System parks vehicle without driver being physically present inside the vehicle. Automatically controls acceleration, braking, steering and shifting.
- Semi-automated parking assistance – Controls steering during parking. Driver responsible for acceleration, braking and gear position. May be capable of parallel and/or perpendicular parking.
- Surround-view camera – Uses cameras located around vehicle to present view of surroundings.
- Trailer assistance – System that assists driver during backing maneuvers with a trailer attached.
Miscellaneous Driving Aids
- Automatic high beams – Deactivates or orients headlamp beams automatically based on lighting, surroundings and traffic.
- Driver monitoring – Monitors driver condition by various means to detect drowsiness or lack of attention.
- Night vision – A system that aids driver vision at night by projecting enhanced images on instrument cluster or heads-up display.
