Advanced Driver Assistance Systems (ADAS) account for 13 percent of total car industry problems, says a new study performed by J.D Power.
In the inaugural J.D Power 2022 ADAS Quality and Satisfaction Study, ADAS account for 23.1 PP100 (problems per 100 vehicles), with lane departure warning/lane keeping assistance and forward collision warning/automatic emergency braking leading the pack, with 6.3 PP100 and 4.6 PP100, respectively.
“As vehicle technologies continue to evolve, manufacturers are working hard at staying innovative,” said senior director of global automotive supplier benchmarking and alternative mobility Ashley Edgar. “Although innovation is important, it is equally important to ensure current technologies, such as collision intervention features, are functioning to the highest degree. If manufacturers want to increase the level of autonomy in the future, today’s features cannot be problematic.”
JDP’s ADAS study is based on the responses from owners of 2022 model-year vehicles who were surveyed after 90 days of ownership. These responses were taken from February through May 2022.
While technologies like lane departure warning and automatic emergency braking are convenient and decrease the likelihood of an accident, they rely on multiple different systems and cameras in order to function properly. As a result, if one of these systems malfunctions, the vehicle’s entire safety technology is rendered unavailable.
GM has an extensive list of Active Safely Technologies designed to avoid a crash or decrease its intensity, including Adaptive Cruise Control, Automatic Braking, and Lane Keep Assist, to name a few. As an example of how complex these technologies are, GM’s Front Automatic Braking system uses the following sensors and cameras, depending on vehicle application:
- Long/mid-range radar + Forward-facing camera + Short range radar
- Long/mid-range radar + Forward-facing camera
- Long/mid-range radar only
- Forward-facing camera only
If just one of the radars in the first application were to fail, the entire Front Automatic Braking system in that vehicle could malfunction. With so many different sensors working in conjunction with each other, all it takes is one problem in one system or camera to act up, and the entire system could fail to operate properly.
