ADAS level 1 and 2: What is the difference?


Automakers in India have taken a huge leap in terms of driver assistance systems and we see new affordable cars equipped with level-1 or level-2 ADAS. So what is ADAS level 1 and level 2? what is the difference between them? We’ll discuss that in today’s article. 

Automakers are set to make major improvements in this area over the next decade as self-driving vehicles transition from science fiction to reality. Consumers are confused about what constitutes self-driving car technology and what does not, as seen by many videos showing sleeping and otherwise inattentive Tesla drivers.

The Society of Automotive Engineers (SAE) established a categorization system that specifies the degree of driving automation a car and its equipment may deliver to establish agreed-upon criteria early in the transition to autonomous cars. The driving automation spectrum ranges from zero to five levels, starting with cars that don’t have this technology and ending with fully self-driving automobiles.

Level 0: There is no automated driving.

A vehicle with no driving automation equipment is classified as Level 0 (zero). In this situation, the driver is solely responsible for the vehicle’s movement, which includes steering, accelerating, braking, parking, and any other action required to move the vehicle in any direction.

At Level 0, however, driver assistance devices that may interfere momentarily during driving may be present. Stability control, forward-collision warning, automated emergency braking, blind-spot detection, and lane-keeping assistance are just some of the features available. Because these technologies do not operate the car, they are classified as Level 0 because they provide alerts or take immediate action in particular situations.

Level 0 cars account for the vast majority of automobiles on American roads.

ADAS Level 1 – Driving Automation

A vehicle has at least one driver support system that offers steering assistance or braking and acceleration assistance at Level 1, the lowest level of automation. The driver is still in charge of the vehicle, and he or she must be ready to take control at any time and for any cause.

Level 1 driving aid technology includes things like adaptive cruise control. It maintains a safe following distance between your car and oncoming traffic without the driver’s participation. A steering aid function like lane-centring or lane-following assistance would also be considered Level 1 autonomy. 

A car that combines both of these characteristics, however, is classified as Level 2 driving automation.

ADAS Level 2 – Partial Driving Automation

Vehicles having advanced driving assistance systems (ADAS) that can take over steering, acceleration, and braking in specified circumstances are classified as Level 2 driving automation. Despite the fact that Level 2 driver assistance can handle these basic driving duties, the driver must stay attentive and actively oversee the technology at all times.

Highway Driving Assist, found in Genesis, Hyundai, and Kia automobiles, is an example of Level 2 driving automation. On highways, the driver must keep her hands on the steering wheel while actively driving, accelerating, and braking the car. Ford’s BlueCruise is a revolutionary hands-free partial driving automation system. It is more advanced than Highway Driving Assist in that it allows the driver to take her hands off the steering wheel on certain, authorized highways in the United States and Canada.

Both of these Level 2 driving automation examples need the driver to remain aware, engaged, and ready to take control at any time. According to what Tesla’s new Full Self Driving Capability technology is informed by the car manufacturer in the State of California, it is a level 2 system and will remain the way when Autosteer for city roads comes as an over the air software update.

For Example – MG Astor – ADAS (Level 2)

MG will offer the Astor with Level 2 Autonomous Driving for the first time in the class. Level 2 refers to the vehicle’s ability to handle steering, braking, and acceleration. It is, however, only possible if particular road conditions are satisfied, and it does need driver interaction.

Adaptive Cruise Control, Forward Collision Warning, Auto Emergency Braking (vehicle and pedestrian), Lane Keep Assist, Lane Departure Warning, Lane Departure Prevention, Speed warning, Speed Assist System, Rear Cross-Traffic Alert, Lane Change Assist, Blind Sport Detection, and intelligent Headlamps Control are among the ADAS features available on the MG Astor.
