Have you ever imagined driving a car that drives itself, brakes when it detects an obstacle, changes lanes and overtakes without your intervention, and takes you to your destination without you having to worry about a thing? Well, that future isn't so distant, thanks to advances in driving technology.
In this article, we'll tell you how driving technology has evolved from automatic braking systems to autonomous vehicles, and how these can improve safety, efficiency, and comfort for drivers and passengers.
What are automatic braking systems and how do they work?
Automatic braking systems are devices that help the driver avoid or reduce the consequences of a frontal collision. These use sensors (cameras, radars, lasers) to detect the presence and distance of other vehicles, pedestrians, cyclists, or objects on the road. When the system detects a risk of impact, it alerts the driver through visual, audible, or tactile signals, prompting them to react and brake voluntarily or change direction. If the driver doesn't respond in time, the system applies the brakes or increases braking pressure to avoid or mitigate the collision. Automatic braking systems are classified according to the type of obstacle they detect (vehicles, pedestrians, cyclists), the speed at which they operate (low, medium, high), or the level of intervention they provide (warning, assistance, intervention). These systems can significantly reduce the number and severity of rear-end accidents , which are the most common on roads.What are autonomous vehicles and how do they work?
Autonomous vehicles are those that can drive themselves without the need for a human driver . These use a combination of sensors (cameras, radars, lasers), digital maps, GPS, and computer systems to perceive the environment, plan the route, and execute driving actions (accelerating, braking, turning, changing lanes, overtaking). Autonomous vehicles can communicate with each other and with infrastructure to share information and coordinate their movements. These are classified according to their degree of automation. According to the scale established by SAE International and ISO , there are six levels of autonomy:- Level 0 : The vehicle does not have any driver assistance systems.
- Level 1 : The vehicle has some driver assistance systems that act on a single driving element (steering or acceleration/braking).
- Level 2 : The vehicle has driver assistance systems that affect two driving elements (steering and acceleration/braking). The driver must monitor the system's operation and be prepared to intervene at any time.
- Level 3 : The vehicle has automated driving systems that perform all driving functions under certain conditions (road type, speed, traffic). The driver must be aware of the surroundings and ready to take control when prompted by the system or when conditions change.
- Level 4 : The vehicle has automated driving systems that perform all driving functions under certain conditions (road type, speed, traffic). The driver does not need to be aware of the surroundings or take control at any time. The vehicle can drive only within a specific geographic area (geofencing).
- Level 5 : The vehicle has automated driving systems that perform all driving functions under any conditions. The driver does not need to be aware of the surroundings or take control at any time. The vehicle can drive itself in any location and situation.
