Level 3 autonomous driving systems represent a significant evolution in mobility, introducing conditional automation in vehicle driving. This level, defined by the Society of Automotive Engineers (SAE) , allows the vehicle to autonomously manage some driving functions in specific conditions, such as on highways or in congested traffic situations. However, unlike the higher levels, level 3 still requires the supervision of the driver, ready to intervene upon request of the system.
Level 3 Systems Features
1. Conditional Automation : Level 3 autonomous driving systems can fully control the vehicle, including acceleration, braking, and steering, but only under certain predetermined circumstances. In these situations, the driver can take their attention off the road, but must remain ready to regain control of the vehicle if the system requires it.
2. Emergency Management : In situations where the system is unable to safely manage driving, such as in adverse weather conditions or on unmapped roads, the vehicle will alert the driver to regain control.
3. Improved Driving Experience : Level 3 systems are designed to improve driver comfort and reduce stress, especially in heavy traffic. This technology is a step up from Level 2 systems, which require constant monitoring by the driver.
Level 3 Self-Driving Cars
Some of the car models that have already introduced Level 3 autonomous driving include:
1. Audi A8 : The Audi A8 was one of the first production vehicles to introduce level 3 autonomous driving with the “Traffic Jam Pilot” system. This system allows the vehicle to autonomously manage driving at speeds of up to around 60 km/h in heavy traffic, allowing the driver to temporarily divert their attention from the road.
2. Mercedes-Benz S-Class : The Mercedes-Benz S-Class has implemented the “Drive Pilot” system, which enables level 3 autonomous driving on certain motorways in Germany. This system is able to fully manage the vehicle in traffic situations, allowing the driver to devote himself to other tasks until asked to regain control.
3. Honda Legend : The Honda Legend model, available in Japan, features a Level 3 autonomous driving system called “Traffic Jam Pilot.” This system allows the vehicle to drive autonomously in slow-moving traffic, with the ability to stop and start autonomously.
Conclusion
Level 3 autonomous driving systems are an important step towards greater automation of driving, offering drivers a safer and more comfortable driving experience, especially in traffic situations. However, the driver must remain alert and ready to intervene when prompted by the system. As the technology continues to evolve, we are likely to see an increasing adoption of these systems in the coming years, with a significant impact on mobility and road safety.
