Detailed Explanations
Traffic Jam Pilot (Level 3): Level 3 automation allows the vehicle to handle all aspects of driving in specific conditions, such as stop-and-go traffic on a highway. The driver can take their eyes off the road and hands off the wheel, but must be ready to take over control if the system requests it. Audi was the first manufacturer to offer a Level 3 system in the A8, but it was later withdrawn due to regulatory hurdles and concerns about driver readiness to retake control. Audi is actively working on refining and re-introducing Level 3 capabilities.
Adaptive Cruise Assist (ACA): Adaptive Cruise Assist is a Level 2 driver-assistance system that helps the driver maintain a safe following distance from the vehicle ahead. It uses radar sensors to monitor the distance and speed of the leading vehicle and automatically adjusts the car's speed to maintain the set distance. ACA can also provide steering assistance to keep the vehicle centered in its lane, but the driver must remain attentive and ready to take control at any time.
Lane Keep Assist (LKA): Lane Keep Assist is another Level 2 feature that helps prevent unintentional lane departures. It uses cameras to detect lane markings and provides steering corrections or warnings if the vehicle begins to drift out of its lane. LKA can be a valuable safety feature, especially on long highway drives, but it is not a substitute for attentive driving.
Park Assist Plus: Park Assist Plus automates the process of parking the vehicle. It uses ultrasonic sensors to scan for available parking spaces and then automatically steers the car into the space, while the driver controls the acceleration and braking. This feature can be particularly helpful in tight parking situations.
Remote Park Assist Plus: Remote Park Assist Plus takes parking automation a step further by allowing the driver to park and unpark the vehicle remotely using a smartphone app. This can be useful in situations where the parking space is too narrow to easily enter or exit the vehicle. The driver maintains control via the app, ensuring safety and precision.
Car-to-X Communication: Car-to-X communication enables vehicles to communicate with each other and with infrastructure, such as traffic lights and road signs. This allows vehicles to share information about road conditions, hazards, and traffic flow, which can improve safety and efficiency. For example, a vehicle that detects a slippery patch of road can warn other vehicles in the area. The effectiveness of Car-to-X communication depends on the availability of compatible infrastructure and the participation of other vehicles.
Predictive Efficiency Assist: Predictive Efficiency Assist uses navigation data and sensor information to anticipate upcoming road conditions, such as hills, curves, and speed limits. Based on this information, it can optimize the car's energy consumption by adjusting the throttle, transmission, and regenerative braking system. This feature is particularly beneficial in electric vehicles, where it can help to extend the driving range.
Sensor Suite: The sensor suite is the foundation of any autonomous driving system. It includes various sensors, such as radar sensors, ultrasonic sensors, cameras, and LiDAR (in some future models), that provide the vehicle with a 360-degree view of its surroundings. Radar sensors are used to detect the distance and speed of objects, ultrasonic sensors are used for short-range detection, cameras are used to identify objects and lane markings, and LiDAR (Light Detection and Ranging) uses laser beams to create a detailed 3D map of the environment.
zFAS (Central Driver Assistance Controller): The zFAS is a high-performance computer that processes the data from the various sensors and controls the driver-assistance systems. It is the "brain" of the autonomous driving system and is responsible for making decisions about how to control the vehicle. The processing power and capabilities of the zFAS unit are constantly being upgraded to support more sophisticated autonomous functions.
Software Platform: The software platform is the underlying software architecture that controls the autonomous driving systems. It includes algorithms for perception, planning, and control. Audi is working on developing its own software platform and collaborating with other companies, like CARIAD (Volkswagen Group's software unit), to accelerate the development process. A robust and scalable software platform is crucial for enabling future levels of autonomy.
Future Plans (Level 4/5): Audi aims to develop vehicles capable of Level 4 (high automation) and Level 5 (full automation) self-driving capabilities in the future. Level 4 vehicles can handle all aspects of driving in specific environments, such as designated highways or urban areas, while Level 5 vehicles can drive themselves in any environment and under any conditions. The timeline for the introduction of Level 4/5 vehicles is uncertain and depends on technological advancements, regulatory approvals, and market demand. Audi is investing heavily in research and development to achieve these higher levels of autonomy.
