Advanced Driver Assistance Systems

Advanced driver assistance systems, also known as ADAS, are systems which aid the driver when they are driving. Car safety as well as road safety are enhanced when an ADAS is designed with a safe human-machine interface. Advanced driver assistance systems were created as to err is to be human. Better driving and increased safety is made possible as these systems have been created to robotize, adapt, and modify vehicle systems. The chance of having a road accident is therefore lessened as human fault is reduced.Negligence and fatigue are the most common reasons for bad driving.

As over a million fatalities are reported per year due to vehicular accidents, the ADAS is a technological blessing. Not only does this system protect the driver and other inhabitants of the car, but it also acts as a safeguard for outsiders such as pedestrians and motorists.

Prominent examples of ADAS:

  • Adaptive Cruise Control
  • Collision avoidance
  • Lane departure warning system
  • Lane centering
  • Wrong-way driving warning
  • Electric vehicle warning sounds (for hybrids and plug-in electric vehicles)
  • Rain sensor
  • Automotive night vision.

Adaptive Cruise Control (ACC)is featured in most modern high-tech vehicles. It is an option which automatically aligns the speed of the car in order to keep a safe distance from vehicles ahead. It is well to remember that the ACC offers a little assistance to the driver in terms of maneuvering the car, but does not take over driving entirely.

Utilizing radar, camera and to a lesser extent, laser, the collision avoidance system (also known as pre-crash system) is designed to prohibit or decrease the severity of a collision. When the vehicle begins to move out of its lane, a lane departure warning system alerts the driver of this, via visual, audio, or vibration warnings. Lane centering is designed for the system to take over driving for a while to steer the car in the correct lane. 

In case the driver is steering the car in the wrong direction, a warning is emitted which contributes to alerting the driver and waking them up from their possible drowsy state. One factor to take into consideration here is that driver fatigue contributes to more than 30% of road crashes.

Electric cars are taking the world by storm in the 21st century. It’s only logical that they come with their own advanced driver assistance systems. Electric vehicle warning sounds, as the name suggests, are sounds which emit from HEVs and PHEVs to alert pedestrians of their presence.

Windscreen wipers are activated automatically when rainfall is detected by the rain sensor. An automotive night vision system utilizes a thermo-graphic camera to enhance a driver’s awareness and scope of sight in obscure areas or during inadequate weather conditions, outside the limits of the vehicle’s headlights.

Examples of the latest ADAS

  • Tesla Autopilot
  • Nissan ProPilot Assist.

The Tesla Autopilot is an evolutionary ADAS created by Tesla. Its many features include, but are not limited to, self-parking, lane centering, ACC, and the capability of robotically changing lanes without human effort. Also, the car can be called upon to and from a garage or any other parking place.

In single lane highway driving conditions, the Nissan ProPilot aids with acceleration, steering, and braking. This system makes use of a front-facing camera, front-facing radar, sensors, as well as an electronic control module.

There are also other groundbreaking advanced driver assistance systems present in the most recent line of automobiles. The 2018 seven-seater compact MPV from Peugeot, the new 5008 SUV GT, features the Hill Assist function. When this mechanism is utilized in combination with the electric parking brake, it keeps the brake on for a limited time (two seconds) when the car is parked on a slope. This featurecomes in handy if you’re driving in Bahrain, a Middle-Eastern region where dangerous slopes are often encountered.

Other advanced driver assistance systems present in the latest car models, such as the 2017 Ford Escape SE and the 2017 Volvo S90, are Blind Spot Monitoring and Automated Parking. Blind Spot Monitoring alerts the driver with a visual cue when another vehicle enters their blind spot. Automated Parking can fully take over the task of parking the car. The cameras on board can detect the relevant space, and then the system is able to maneuver the car into that particular place. Parallel parking is common but some systems are also capable of parking the car into a horizontal spot.
