2018 VW Arteon Innovative Driver Assistance Systems
2018 VW Arteon Innovative Driver Assistance Systems.
They are fractions of a second which matter at night: a section of country road that has many bends, a bend in a residential area with poor road lighting – and there might be an obstacle in the dark somewhere on the road. The Arteon is the first Volkswagen to offer a dynamic cornering light with new predictive control functionality. The LED dual headlights illuminate the upcoming bend up to two seconds sooner before the vehicle is even steered into it. The Arteon’s new lighting system develops these ‘clairvoyant’ powers by networking with the front camera and the navigation system.
The Active Lighting System – a technology package – utilises LED dual headlights with ‘projector lenses’ and integrates, among other functions, Dynamic Light Assist – the dynamically controlled permanent main beam (interactive permanent main beam as functional extension of Light Assist) – and the ‘dynamic cornering light’. The latter steers the headlights into bends according to steering angle using headlight modules with variable control. A new aspect in the Arteon is the ability to do this independently of the steering angle, and even predictively, based on images from the front camera and route data from the navigation system. In this manner, the gran turismo is able to illuminate the upcoming bend in the road before the driver steers into it. Another reason for aiming the headlight pattern along the path of the curve is to avoid wasting light illuminating the roadside.
The Arteon is a gran turismo, ideal for long distances. The new, optionally available “adaptive cruise control ACC” with predictive speed control gives enhanced comfort over long distances. The further developments in “ACC” can integrate speed limits for the first time. So far, the assistance system was known purely as cruise control: adjust the desired speed, that’s all. Within system limits, “adaptive cruise control ACC” can take over braking and acceleration. So far, so good. However, anyone who has ever driven a car with “ACC” will have wished that the system could “think” and also take into account bends and speed limits, thus adding even more comfort. The Arteon is the first Volkswagen to do just that: within system limits, it reacts to bends and speed limits and integrates them into the adaptive speed control.
It’s a scenario that no one wishes for: traffic lights on red, a look in the rear-view mirror, the vehicle behind is approaching much too fast – a rear-end crash is looming. In such situations, the new, optional ‘Pre-Crash occupant protection system’ in the Arteon now provides assistance to the limit of its capabilities. For the first time, the Pre-Crash sensors are able to react not only to processes relating to driving dynamics (detected by functions such as the ESC) and to acute risks of collision from the front (registered by Front Assist), but also to hazards at the rear. For this the system uses data from Side Assist. Within fractions of a second it is able to initiate measures to lessen wherever possible the consequences of any accident.
This is how it works: Pre-Crash utilises the sensors of the Side Assist system, which during overtaking provides within the limits of its capabilities a warning of any vehicle in the ‘blind spot’. Via radar sensors Side Assist is able to register the position and speed of the cars behind the Arteon. This data is then analysed by the Pre-Crash system. It does this not only when the car is moving, but also when it is stopped with the engine running and in stop-start mode, e.g. at the aforementioned red light. If the detected vehicle moves towards the Arteon, the system uses the position and speed of both cars to determine the probability of a possible collision. If the new Pre-Crash system detects an imminent risk, it duly reacts.
‘Autonomous driving’ – a term currently generating more animated discussion than almost any other in the automotive world. It fascinates and polarises in equal measure. The fact is: automated driving functions increase comfort and often safety as well. The new Arteon is therefore fitted with more driver assistance systems than any Volkswagen before. These systems are interconnected with each other, as it is the interaction of their sensors and computers that actually makes autonomous driving functions possible. Through the fusion of four driver assistance systems, the Arteon possesses a form of technology that in many circumstances can help to prevent serious accidents: Emergency Assist 2.0. As soon as the sensors of the avant-garde gran turismo notice that the driver has become incapacitated, the Arteon takes over the proverbial helm. Within the bounds of its system capabilities, it warns other road users and automatically steers to the nearside lane, where it stops.
