ADAS: The Elephant in the Room
Nov. 17, 2020—One of the first events in AAPEX’s Virtual Experience tackled a topic that has been on the minds of many in the automotive industry—Advanced Driver Assistance Systems.
The Nov. 3 presentation was conducted by Bosch and outlined the importance of ADAS features and its reliance on radar and camera systems.
Advanced Driver Assistance Systems aim to provide a safe driving experience by alerting drivers to potential dangers that may otherwise go unnoticed, like a shift in the flow of traffic.
ADAS capabilities include a variety of features and are becoming increasingly more complex as well as intuitive. What started as a simple cruise control setting now spans lane change departures, emergency braking assist, and many more.
According to Bosch, the purpose of ADAS is to provide a safer driving experience for the driver and passenger as well as the surrounding environment of the vehicle.
Simply put, ADAS features produce reactions far faster than a human is capable of, noted the presentation.
By utilizing camera and radar sensors placed throughout the vehicle, ADAS features can apply corrective action when a situation necessitates it.
Lane departure warnings, for example, are made possible by camera sensors which monitor the vehicle’s position within the lane. When a vehicle is drifting out of the lane without a blinker or other signal, lane departure warning emits an audible warning for the driver.
Radar functions by sending out electromagnetic energy waves in order to determine the time and distance between an object and a vehicle.
ADAS features such as emergency brake assist use radar to detect an object in the path of travel, alerting the vehicle and the driver to a potential danger. Radar is then used to apply the brake pressure necessary to avoid a collision within the distance provided.
ADAS features provide a multitude of safety and precautionary measures, but there is a catch. If not calibrated properly, these safety systems could also cause accidents while trying to avoid them.
When a vehicle suffers a collision, the damage is visible on the bumper, door, and so on. When a camera or radar sensor is damaged, it will not reveal itself to the naked eye. That is why after the collision repair procedures are complete, ADAS features must be recalibrated to ensure the accurate and effective use of the safety features.
