Active ADAS Systems & Driver Safety Features

active adas systems

Active Advanced Driver Assistance Systems (ADAS) are revolutionizing how we navigate our
roads, enhancing safety, and improving the driving experience. These systems work actively to avoid potential hazards by interpreting the environment around the vehicle and acting accordingly to ensure driver safety. Below, we will also explore how they contribute to improving driver safety and the future of these rapidly advancing systems.

What is an Active ADAS System?

Active Advanced Driver Assistance Systems (ADAS) are systems that don’t just warn the driver but also actively take control of certain vehicle functions to prevent accidents or improve driving comfort. Equipped with sensors and cameras, these systems can detect hazards, evaluate potential risks, and take preventive actions to prevent accidents. Examples of popular active ADAS features include:

Lane Keep Assist (LKAS):

LKAS uses cameras to detect lane markings on the road. Suppose the system detects that the vehicle is unintentionally drifting out of its lane without a turn signal activated. In that case, it will gently steer the car back into the lane or provide steering input to avoid crashes.

Automatic Emergency Braking (AEB):

AEB systems monitor the road ahead using sensors. If an imminent collision is detected, and the driver doesn’t react in time, the system will automatically apply the brakes to prevent or mitigate a collision.

Parking Assistance:

Parking assistance systems can actively help park the car, either by providing steering input for parallel or perpendicular parking or, in more advanced cases, controlling acceleration, braking, and gear changes. Some vehicles are equipped with remote parking assistance, meaning the car can park without the driver being behind the wheel.

Adaptive Cruise Control (ACC):

ACC adjusts the vehicle’s speed to maintain a safe following distance from the vehicle ahead. It uses sensors (like radar, LIDAR, or cameras) to monitor the vehicle’s speed in front and will decelerate as necessary. Once the road is clear ahead of the car, the system will accelerate back to the set cruise control speed.

Adaptive Headlights:

Adaptive headlights are designed to automatically adjust the direction and intensity of the vehicle’s headlight beams based on various factors, such as the vehicle’s speed, steering angle, and external lighting conditions. Their primary goal is to enhance nighttime driving visibility without blinding oncoming drivers.

Traffic Jam Assist (TJA):

In heavy traffic situations, TJA can control the steering, acceleration, and braking to follow the vehicle ahead, maintaining a safe distance and staying within the lane. This system can help to reduce accidents in rush hour situations and make driving in heavy traffic less stressful.

These Active Advanced Driver Assistance Systems (ADAS) contribute significantly to a safer, more comfortable, and less stressful driving experience. It is important for drivers to understand how these systems work and their limitations to fully utilize and benefit from them.

Advantages and Limitations of Active Safety Systems

Advantages of Active ADASLimitations of Active ADAS
Increased safety: Active ADAS can significantly reduce the risk of accidents by assisting in complex driving situations.Dependence on sensors: These systems rely heavily on sensors, which can fail or be obstructed, leading to potential malfunctions
Improved comfort: Systems like Traffic Jam Assist can make driving in heavy traffic less stressful and tiring.Limited capabilities: Currently, ADAS can only assist, not replace, drivers. Human intervention is still required in many scenarios.
Enhanced visibility: Adaptive headlights improve nighttime visibility, making driving safer.Weather conditions: Bad weather can interfere with the functioning of these systems, reducing their reliability.
Fuel efficiency: By maintaining optimal speed and reducing abrupt acceleration and deceleration, systems like Adaptive Cruise Control can help improve the vehicle’s fuel efficiency.Cost: Installation and repair of these systems can be costly.

In addition to the advantages and limitations mentioned above, there are also industry challenges that need to be addressed for active safety systems to reach their full potential. These challenges include:

  • Standardization: With multiple manufacturers implementing different ADAS technologies, there is a lack of standardization in terms of features and functionalities. This can make it difficult for consumers to understand and compare different systems.
  • Liability: As with any technology, there is always the question of liability in case of accidents or malfunctions. In the case of ADAS, determining who is responsible for an accident can be complex and may involve both the driver and the manufacturer.
  • Cybersecurity: With increasing vehicle connectivity, there is also a growing concern about cybersecurity. Hackers could potentially gain access to ADAS systems, compromising their functionality and safety.
  • Data privacy: Active safety systems collect a significant amount of data, including information about the vehicle’s surroundings and driver behavior. There are concerns about how manufacturers collect, use, and share this data.

Despite these challenges, active safety systems continue to evolve and improve to enhance the overall driving experience.

How do Active Systems Increase Driver Safety?

Active Safety Systems enhance driver safety in many ways, acting as a set of extra eyes on the road and even correcting vehicle course if necessary.

Take the example of a driver who is momentarily distracted on a busy urban road. An unforeseen obstacle, like a pedestrian appearing suddenly, could lead to a potentially fatal accident. However, with the AEB system in place, the car would autonomously detect the pedestrian and apply the brakes, potentially saving lives.

Another real-world example of these systems at work can be seen with Lane Keeping Assist (LKA). Imagine a scenario where a driver is navigating a highway at night, feeling fatigued. There’s a real risk of the vehicle unintentionally drifting out of its lane, leading to catastrophic consequences. In such situations, the LKA system would detect the drift and gently steer the vehicle back into the correct lane.

Active safety systems play a crucial role in augmenting driver awareness, providing real-time intervention in critical scenarios, and ultimately making roads safer for everyone. However, drivers cannot fully rely on these systems and should always be aware while driving.

What’s Next for Active ADAS Systems?

The future of Active ADAS systems is dynamic, with continual advancements and innovations to further enhance safety. These systems are steadily evolving by incorporating more sophisticated sensors, enhanced AI capabilities, and better integration with vehicle dynamics. As the backbone of fully autonomous driving, the advancements made in Active ADAS systems are pivotal to bringing us closer to achieving Level 4 autonomous driving.

This level of autonomy would bring about a monumental shift in our approach to transportation, making the roads safer and more efficient. However, we must bear in mind that achieving this requires rigorous testing and validation to ensure the absolute safety of these systems.
