Advanced driver-assistance systems or in short known as ADAS is a combination of many sensors and cameras that assists the driver in various driving and parking functions. These functions and combinations are further divided into 6 levels ranging from 0 to 5, where 0 means absolutely no assistance with a complete manual functioning where the driver has the sole control and level 5 being a fully autonomous system where the vehicle performs all the necessary functions as it fells suited for your ride, with 0 interaction or any sort of attention required. However, the topic today we are going to discuss is the ADAS level 1 System and the functions and features included in it.

Keeping ADAS Level 0 aside which contains zero autonomous functionality even considering the preventive safety systems which are only operated via driver’s application of it.

Features included in ADAS level 1

Although ADAS Level 1 and Level 2 have very slight deference as both these levels require the decision making of the driver, the deference is that the Level 1 System can only work on a single function at a time while the Level 2 can control multiple features at the same time.

 ADAS Level 1 consists of features like adaptive cruise control, emergency brake assist, lane keep & centring assist and automatic emergency brake assist.

Adaptive Cruise Control

Features included in ADAS level 1
Adaptive cruise control

The first feature of ADAS level 1 is a feature which many of you might be familiar with, while for others, it is a system that can maintain a specified speed and distance with regards to the vehicle ahead. This system is considered as autonomous level 1 because it can automatically accelerate or even apply brakes considering the distance between the vehicle ahead, however, ACC also requires the driver to be alert and take the wheel if necessary. Although this feature is petty convenient for highways but it has its limitations like what if the car ahead changes its lane or someone cuts your lane in between which is quite often a phenomenon in India, therefore the need for an alert driver.

Emergency Brake Assist

The Second feature of ADAS Level 1 is the Emergency Brake Assist which is a function that helps or assists you to apply abrupt brakes if you for some reason you apply sudden brakes due to anything on the road but weren’t able to press the pedal all the way. This system then senses this situation and applies the remaining force to further push your brake pedal to the extreme which will allow your ABS to kick in for smoother and proper braking without losing control over your car. This feature is considered autonomous because of the fact that the car takes action for itself considering your reaction to the situation.

Keep in mind that if Emergency Brake Assist applies to your brakes then the brake pedal doesn’t reset immediately however you can reset it by pressing it a few times.

Automatic Emergency Brake Assist

AEBA

Some of you might consider both Emergency Brake Assist and Automatic Emergency Brake Assist as the same at first glance however both these functions differ largely. While the Emergency Brake Assist has been discussed above, the Automatic Emergency Brake Assist uses an algorithm based on its sensors to detect nearing pedestrians, cyclists or in some cases even other cars and apply brakes to minimize or avoid serious impact. While the Emergency brake assists only activate when the driver pushes the brakes the Automatic Emergency Brake Assist does not require the driver’s permission or engagement as such.

Lane Keep and centering Assist

Features included in ADAS level 1

This ADAS level 1 feature is quite self-explanatory by the name, this feature comprises of two parts first being the lane keep assist which works in keeping you inside the lane by the use of various cameras and sensors around your car, in this features if your car inclines of either edge of the lane a warning sign is beeped on your cluster and the steering vibrates slightly to get your attention, however, this can be overridden with a slight nudge on the steering. But this function won’t work if the lane markings are faint or aren’t visible due to any reason like snow or any other thing. The other part is lane-centring which activates if while coming to the lane’s edge you ignore the warning or steering vibration signal and do not nudge the steering in this case the car will take over the control in its hands and will steer you to the centre of the lane.
