ADAS is an Advanced Driver Assistance System which is a passive and active safety system designed mainly to remove the human error component when operating a vehicle of any type. ADAS system mainly uses advanced technologies which help in assisting the driver during driving and this also helps in improving the driver’s performance. ADAS also uses a combination of sensor technologies which mainly focus on perceiving the world around the vehicle and also provide information to the driver so necessary actions are taken. Interested aspirants who wish to know about ADAS must enroll for Adas Technology Courses In Pune

ADAS systems are mainly used in cars, trucks, and buses as well as farming, construction, and military vehicles. 

How does ADAS work?

ADAS works by alerting the driver to danger or even taking any action to avoid any accident. ADAS-installed vehicles sense the environment around themselves which helps in processing the information quickly and accurately in the computer system and this also provides the correct output to the driver.

ADAS-equipped vehicles form an array of advanced sensors which augment the eyes and ears and help in making a quick decision. ADAS system mainly consists of a couple of sensors, and interfaces and has a powerful computer processor which integrates the data and makes a decision in real-time. 

The sensors mainly examine the outside condition around the vehicle and also provide information to onboard ADAS computers for prioritization and action. These have helped in saving many lives by preventing accidents that could not happen without ADAS.

Passive ADAS System:

Irrespective of the number of sensors installed, a passive ADAS system, the computer informs the driver of any unsafe condition. The driver takes action for preventing the condition that results in an accident. The main warning includes sounds and flashing lights. 

Common Passive ADAS Function includes:

  • ABS- Anti-lock braking system: this keeps the car from skidding and turning when emergency brakes have to be applied. 
  • ESC- Electronic Stability Control: helps the driver in avoiding any condition, especially during the unexpected driving condition. 
  • TCS- Traction Control System: includes different aspects of both ABS and ESC above which helps the driver in maintaining adequate traction. 
  • Back-up camera: helps the driver with a view behind the car during parking
  • LDW- Lane Departure Warning: notifies the driver if the vehicle is not keeping in the lane zone. 

Active ADAS Systems:

In an active ADAS System, the vehicle takes complete action. Let us look at the common functions:

  • Automatic Emergency Braking: automatic bracks helps in avoiding hitting a vehicle ahead. 
  • Self-parking: self-maneuvering into parking spaces. 
  • Traffic jam assists: combines adaptive cruise control and lane keeping which helps in providing semi-automated driver help during dense traffic events. 

Conclusion: 

ADAS is a single important type of development that is persistent nowadays. There are hybrid and electric-powered developments. Numerous institutes offer ADAS Certification In Mumbai. ADAS mainly goes directly into the most important aspect of travel and maintaining human safety. Since more than 90% of road accidents and injuries which occur due to human error must prevent injuries and deaths.
