The automotive industry has made remarkable strides in improving the driving experience, comfort and safety over the years. One notable advancement in this regard is the development and integration of Advanced Driver Assistance Systems (ADAS) into vehicles.
ADAS encompasses a range of technologies designed to assist drivers and automate tasks to enhance on-road experiences. Utilising the different levels of autonomy, ADAS is paving the way for the future of autonomous driving. A future where vehicles will be capable of safely navigating through prescribed routes without any human input.
We’ll now take a closer look at how ADAS technology is turning sci-fiction into reality.
How Does Advanced Driver Assistance System Work?
Whether in a car or a bus, ADAS technologies are installed to ensure safety and stability behind the wheels. ADAS-equipped vehicles feature an array of advanced cameras and sensors. These components are synchronised to augment the visual, auditory and decision-making capabilities of the human driver.
More About ADAS Applications
As autonomous technologies continue to evolve, the scope of ADAS applications is also expanding. Here are different ways driver assistance technologies are integrated into a car’s active and passive safety systems nowadays.
Integration of ADAS: Active and Passive Systems
Whether of active or passive nature, the advanced driver assistance systems architecture typically has a powerful computer processor at its core. It helps the system process information collected from the cameras and sensors to take real-time decisions, minimising hazards.
Passive ADAS Functionalities
A passive ADAS system is where the car’s computer warns the driver about an unsafe condition. The driver is then required to respond immediately to avoid accidents.
Typical alert methods in passive ADAS functionalities include sounds, flashing lights, and sometimes physical feedback. For instance, a steering wheel may vibrate in blind spot detection systems. It warns drivers when they engage in unsafe overtaking manoeuvres.
Some common examples of passive ADAS systems in vehicles are:
Anti-lock Braking Systems (ABS)
It prevents the car from skidding and losing control during emergency braking. The anti-lock braking system (ABS) has become a staple safety feature in every other modern car.
Electronic Stability Control (ESC)
The electronic stability control (ESC) system helps maintain the vehicle’s stability and control in unexpected driving conditions. It automatically detects loss of traction and applies brakes, if necessary, to bring the car back on track
Traction Control System (TCS)
Combining the functionalities of ABS and ESC, the traction control system (TCS) aids the driver in maintaining optimal traction. This allows safer navigation through turns and curves.
Back-up Camera
The backup camera is also a type of passive ADAS system. It provides the driver with a clear view behind the car, facilitating parking and reversing manoeuvres.
Lane Departure Warning System
The lane departure warning system notifies the driver if the vehicle deviates from its lane, prompting them to take corrective action. The technology is also very useful in terms of maintaining lane discipline in the UAE and avoiding any penalties.
Forward Collision Warning
It is one of the must-have modern car safety features. Using advanced sensors, it timely notifies the driver to apply the brakes to prevent a collision. However, in some modern vehicles, the forward collision warning (FCW) system also applies brakes alongside alerting the driver.
Blind Spot Detection
The blind spot detection system warns the driver of the presence of a vehicle in their blind spot. It ensures safer lane changes and manoeuvres while cruising.
Driver Fatigue Detection System
The driver fatigue detection system uses car cameras for eye movement tracking and other types of sensors to detect signs of driver fatigue. If the driver’s motion differs from their typical behaviour, an acoustic or sensory alarm goes off.
Mercedes-Benz’s Attention Assist, BMW’s Driver Alertness Monitoring and Volvo’s Driver Alert Control are a few noteworthy examples in this regard.
Parking Assistance
It alerts the driver when the vehicle’s front or rear bumpers approach nearby objects at low speeds. A parking distance control (PDC) system can be of great help when parking or navigating tight lanes.
Active ADAS Functionalities
Active ADAS applications allow a vehicle to take action proactively when it comes to enhancing driving experience and safety. Some noteworthy examples of active ADAS systems include:
Automatic Emergency Braking
The vehicle automatically applies the brakes to avoid collisions with vehicles ahead, pedestrians, animals, or any obstacles in the lane. This feature is usually paired with the FCW systems in modern cars.
Emergency Steering
In this system, the car uses emergency steering technology to steer clear of objects in its lane, avoiding collisions.
Active Steering
In active steering, the system monitors the driver’s steering input and alters it intelligently according to the road conditions. BMW Active Steering and Nissan Direct Adaptive Steering are the two brand-specific examples in this regard.
Adaptive Cruise Control
It’s a type of ADAS where the system adjusts the car’s speed to match it with the vehicles ahead. However, the working and types of adaptive cruise control systems may vary for different makes and models.
Self Parking
The vehicle can autonomously manoeuvre itself from the traffic lane into a parking lot. Most self-parking cars are capable of fitting themselves in parallel, perpendicular and angle parking positions.
The aforementioned active advanced driver assistance systems primarily cover the basic levels of autonomy for driver assistance and safety.
ADAS and the Future of Mobility
Advanced brand-specific ADAS features like Tesla’s Autopilot and GM’s Super Cruise are based on high-tech, semi-autonomous driving systems. Such innovations are paving grounds for the large-scale adoption of fully autonomous vehicles.
Mobility solutions have come a long way making driverless cars safer than human drivers to some extent. That said, many challenges in self-driving technology still need to be overcome to make it safe for widespread adoption.
This brings us to the end of our detailed piece on advanced driver assistance systems. By making our roads safer and more driver-friendly, ADAS technology is driving us closer to the future of mobility.
If you also want to benefit from the different ADAS features, consider buying a car from the following manufacturers.
