Advanced Driver Assistance Systems – A Brief Overview


Advanced Driver Assistance Systems (ADAS) are a group of vehicle safety systems designed to enhance vehicle safety through various technologies that alert the driver to potential problems or to avoid collisions by implementing safeguards and in certain instances, taking over certain functions of the vehicle.

ADAS is generally categorized into 4 groups – Adaptive, Automated, Monitoring and Warning. Let’s take a closer look at each of these groups and how they aid the driver in reducing road accidents.

Adaptive driver assistance systems are equipped with features that are able to change/adapt according to the situations surrounding the vehicle. For example, adaptive cruise control. Vehicles fitted with adaptive cruise control allows drivers to maintain an optimum distance between vehicles without the need of a driver’s action to control the speed of the vehicle. This feature is initiated with the help of sensors and radars fitted in front of the car that measures and calculates the distance between vehicles.


Automated driver assistance systems are fitted with technologies that are able to take over and perform certain functions of a vehicle. An example would be, autonomous emergency braking (AEB). Various vehicles are fitted with this technology including Perodua’s Myvi. With the help of sensors and cameras, AEB will take action autonomously upon detecting imminent collision. These actions include braking or steering away from the subject of collision.

A number of driver assistance systems are designed to monitor certain conditions of the car through sensors, cameras, or other means. Driver assistance systems of this kind may also observe the surrounding area or driving condition of the vehicle and assess the presence of a complication among/surrounding the vehicle upon which the driver will receive a warning which can be in either of these forms – visual, audible, vibration tactile. One common example would be the blind spot monitoring system. The blind spot monitor is fitted with technologies that are able detect the presence of an object within the driver’s blind spot. If a vehicle is detected to be within the blind spot area, the driver will receive an indication. This increases the awareness of the driver, allowing the driver to be vary of the surrounding.


This kind of driver assistance system alerts the driver to potential issues in their own driving or the driving of others. Some assistance systems under this category will go a step further and take over certain functions of the vehicle if the system detects imminent danger. One example would be – Lane departure warning. Lane-keeping assistance systems leverages on the variety of sensors around the vehicle to make sure a vehicle doesn’t leave its lane. If the system determines that the vehicle is departing its lane, the system will send a warning notification so that the driver can take a corrective action in time to avoid unwanted consequences. Certain lane departure warning systems are fitted with autonomous capabilities – it can automatically steer the vehicle back into its lane if a driver doesn’t take any corrective measures within a set time limit.

Road safety has always been a concern for authorities, governing bodies and the public alike. With the implementation of ADAS, the standard of road safety will be increased, making vehicles even more roadworthy. In addition to that, ADAS may also be a stepping stone towards the production of autonomous vehicles as most of the features provided in ADAS are initiated automatically. Although some features in ADAS are equipped with the capability to take preventive measures, they are actually designed to reduce road accidents and not to prevent them. Hence, a driver, being the main operator of a vehicle, must always take into the account the safety of all road users.
