Self-driving car levels
As a rule, autonomous vehicle technology is divided into 6 different levels:
- Level 0 – No automation: the driver performs all the driving tasks.
- Level 1 – Driver assistance: the driver must perform most of the tasks necessary to control the vehicle, which is equipped with some features that assist the driver in navigating the car.
- Level 2 – Partial automation under the supervision of the driver: the car not only has a single driver assistance system, but also has Advanced Driver Assistance Systems – ADAS – which helps the vehicle to steer, accelerate, and brake automatically in complex situations. Drivers are still required to actively participate in the driving process, in particular, they must keep their hands on the steering wheel as well as monitor the direction of the vehicle’s movement.
- Level 3 – Conditional driving automation, with driver: This level is also known as conditional automation, with many driver assistance systems programmed to make decisions (by artificial intelligence – AI) in real time based on changes in the traffic environment around the car. Although the Level 3 autonomous car can operate without driver involvement, the driver is still required to be present to take control of the vehicle, especially in emergency situations due to system failure.
- Level 4 – Conditional driving automation, without driver: Level 4 autonomous cars do not require any driver interaction during vehicle operation, as the car is programmed to stop automatically in the event of a system failure. Thus, in most practical conditions, the driver does not need to intervene to control the vehicle. Even so, weather conditions can limit the performance of Level 4 autonomous cars. At this point, it all depends on the technology that the car is equipped with. For example, some smart cars use LiDAR sensor technology to analyze surroundings without being affected by weather factors.
- Level 5 – Full driving automation: At this level, the car fully automatically moves and handles the situation in real time without any interaction from the driver. At level 5, vehicles do not have a steering wheel, accelerator, brake pedal, or even a rearview mirror like traditional cars.
Models equipped with ADAS in Vietnam
In Vietnam, most low-cost popular car models are currently classified as level 0 in driving automation. Recently, more and more popular cars have started to be equipped with 2 driving assistance systems at level 1. After Ford with the Ranger and Everest, Mazda respectively launched the CX-8 and Mazda3 with the i-Activsense safety package, and Toyota introduced the Corolla Cross which is equipped with the TSS package. In addition, many models of Mercedes-Benz, Audi, BMW, Jaguar, and Land Rover are also classified as level 1 autonomous cars.
Level 2 self-driving cars include Tesla’s Autopilot, Volvo’s Pilot Assist, or Audi’s Traffic Jam Assist. Currently, except for privately imported high-end Tesla models, of which the autonomous system has not worked effectively in Vietnam, there are only two models – the VF8 & VF9 – that have the level 2 ADAS and surround analytics LiDAR sensor.
Why is the VF 8 outstanding?
As a pioneering Vietnamese brand in the production of “green” cars, VinFast stays ahead of technology trends by integrating a series of ADAS features into our product range. With the ability to instantly detect potential hazards and dangers, issue warnings, and intervene in time, the ADAS smart technologies integrated into VinFast electric cars promise to bring an outstanding safety experience to users. Specifically:
VinFast has successfully put ADAS into practice, starting with the VF e34 and then the VF 8. The group of ADAS technologies applied to the VF 8 cars is effective on many different roads, even on the highway at times of congestion.
In traffic jams, the car can automatically adjust its speed to maintain an appropriate distance from the vehicle ahead without the need for brake or accelerator operation.
On the highway, the steering assist feature helps the car automatically adjust its speed to keep a safe distance from other vehicles by increasing or decreasing speed. The car can even automatically overtake another vehicle when it detects a safe gap while keeping the correct lane position
On slightly curved roads, the advanced steering assist feature also helps the car move safely in the lane without having to hold the brake, gas pedal, and steer. Even when accelerating, the car still takes turns stably without bouncing or overturning, helping to increase the safety in movement.
The forward collision warning is one of ADAS’s most impressive functions. When moving, if the ADAS system detects that a pedestrian on the road is likely to cause a collision, it will emit a warning sound, and at this time the car will quickly and accurately automatically brake.
When moving in restricted visibility, ADAS can also help the car automatically steer to avoid obstacles.
According to research results from the Insurance Institute for Highway Safety, rear-end car accidents is reduced by up to 27% thanks to a forward collision warning system; the number of fatal accidents decreases by 21% owing to the lane departure warning devices; and lane collisions reduce by 14% by virtue of the blind spot warning function.
In fact, the real-life experience of the VinFast VF 8, as well as the research results of the Insurance Institute for Highway Safety, depicted the great advantages of ADAS technology applied in cars. However, it is important to note that smart technology will not make the car completely self-driving, drivers still need to remain focused while driving and monitor the car’s systems to intervene promptly in case of incidents.
