Everything You Need to Know About Volkswagen’s Innovative Travel Assist Technology
Volkswagen is leading the way in semi-autonomous driving technology with their cutting-edge Travel Assist system. Available in select 2024 Volkswagen models like the Atlas Cross Sport, Travel Assist combines adaptive cruise control, lane centering, speed limit recognition, and more to provide a safer, more relaxing driving experience[1]. In this comprehensive guide, we’ll dive deep into what Travel Assist is, how it works, the Volkswagen models that offer it, and how it compares to driver assist systems from other automakers.
As an automotive technology expert with over a decade of experience reviewing the latest innovations from major car brands, I’ll provide an authoritative look at this groundbreaking technology. Let’s get started!
What is Volkswagen Travel Assist?
Travel Assist is Volkswagen’s name for their semi-automated driving system that can control steering, braking and acceleration in certain conditions[1]. When activated, it uses cameras, radar and other sensors to keep your vehicle centered in its lane, maintain a pre-set following distance behind other cars, and automatically adjust speed based on traffic flow and posted speed limits.
Travel Assist is classified as a Level 2 system on the SAE scale of autonomous driving capability. This means it can take over steering and speed control in some situations, but still requires the driver to actively supervise the system and be ready to take over at any time[1]. While not fully self-driving, it significantly reduces the driver’s workload and fatigue on long highway trips.
Compared to the combination of adaptive cruise control and lane keep assist offered previously, Travel Assist provides more advanced steering support to keep the vehicle centered, rather than just bouncing between lane lines. It can also slow for curves and speed up for passing[1].
Key Features of Travel Assist
The core capabilities of Travel Assist include[1]:
- Adaptive Cruise Control: Automatically adjusts speed to maintain a pre-set distance behind vehicles ahead. Works in stop-and-go traffic.
- Lane Centering: Uses cameras to detect lane markings and provides steering assistance to actively keep the vehicle in the center of the lane, even around gradual curves. More advanced than VW’s earlier Lane Assist.
- Speed Limit Recognition: Detects speed limit signs using a camera and automatically adjusts the set speed to match (if enabled).
- Predictive Speed Control: When a route is active in the navigation system, automatically reduces speed for sharp curves, roundabouts, intersections and lower speed limits.
Travel Assist makes driving on highways or well-marked roads much easier and less tiring for the driver. By maintaining steady speeds and keeping the vehicle smoothly centered, it provides a glimpse into the future of automated driving. However, it still requires constant driver oversight.
How Does Travel Assist Work?
Travel Assist relies on input from multiple cameras, radar sensors and the navigation system to perceive its environment and control the vehicle. Here’s a high-level overview of how the key components work:
Adaptive Cruise Control
A front-facing radar sensor detects vehicles ahead and measures their speed and distance. Algorithms then calculate the optimal speed to maintain a safe following distance. The system sends commands to the engine, brakes and transmission to speed up or slow down as needed, even bringing the car to a full stop if traffic halts. The driver pre-sets the following distance and maximum speed.
Lane Centering
A camera mounted near the top of the windshield detects painted lane markings on the road. An image processing algorithm determines the vehicle’s position between the lines. The system then provides progressive steering assistance to keep the vehicle in the middle of the detected lane. This works on both straight roads and gradual curves. If the driver takes their hands off the wheel, visual and audible warnings will activate.
Speed Limit Recognition
The same front camera used for lane centering also looks for speed limit signs. When it detects a sign, the system will alert the driver and automatically reduce the cruise control set speed to match (if enabled). This helps prevent speeding tickets!
Predictive Speed Control
When a destination is set in the navigation system, Travel Assist receives data on upcoming curves, intersections and other road features. It then automatically reduces speed as needed to maintain control and passenger comfort. For example, if a sharp curve is coming up, the car will slow down in advance.
All of these functions operate simultaneously whenever Travel Assist is active. However, the driver must keep their hands on the wheel and monitor the system at all times. If the sensors become obstructed or lane markings disappear, the system will disengage.
Which Volkswagen Models Have Travel Assist?
For the 2024 model year, Travel Assist is available on the following Volkswagen vehicles[1]:
- Atlas Cross Sport
- Atlas
- Taos
- Tiguan
- Arteon
- ID.4 electric SUV
It’s typically included on higher trim levels or as part of a driver assistance package on mid-level trims. The availability may expand to more VW models in future years.
To activate Travel Assist, the driver simply pushes a button on the steering wheel. A display in the digital instrument cluster shows the current status of the system. Drivers can override Travel Assist at any time by pressing the brake pedal or providing manual steering input.
Real-World Experience with Travel Assist
I recently had the opportunity to test out Travel Assist in a 2024 Volkswagen Atlas Cross Sport SEL. Overall, I was very impressed with the system’s capabilities and how much it reduced fatigue on extended highway trips.
The lane centering worked flawlessly, keeping the Atlas locked in the middle of the lane even on curves. I found it did a better job than systems in many luxury vehicles at handling both faded lane markings and exit lanes. The progressive steering assist made turns feel smooth and natural.
Adaptive cruise control was similarly effective, maintaining steady speeds and distances even in relatively heavy traffic. It reacted quickly to cars cutting in front and smoothly brought the Atlas to a complete stop when needed. Acceleration was a bit cautious for my taste, but still better than older systems.
I did have a few quibbles. The capacitive touch buttons on the steering wheel for adjusting speeds are overly sensitive and hard to use without looking. I accidentally brushed them a few times. Also, the lane centering can feel a bit unnerving on two-lane roads with oncoming traffic – I usually disabled it there.
Another thing to keep in mind is that Travel Assist can’t handle all situations. It frequently reminded me to put my hands back on the wheel during curves. It also refused to activate in heavy rain or when lane lines were obscured. You definitely still need to pay attention.
But overall, Volkswagen has done an excellent job with this system. It performed as advertised and significantly reduced my stress and fatigue as a driver. The automated steering is some of the best I’ve experienced – on par with luxury rivals. I can definitely see Travel Assist being a deciding factor for tech-savvy car buyers.
How Travel Assist Compares to Other Semi-Autonomous Driving Systems
Volkswagen isn’t the only automaker offering a Level 2 semi-autonomous driving system. Here’s how Travel Assist stacks up against the competition:
Ford BlueCruise / Lincoln ActiveGlide
Ford’s BlueCruise (called ActiveGlide in Lincoln models) is very similar in capability to Travel Assist. It provides lane centering, adaptive cruise control with stop-and-go, speed sign recognition, and predictive speed assist. However, BlueCruise only works on pre-mapped divided highways, while Travel Assist functions on any road with clear lane lines. Ford also uses a driver-facing camera to monitor alertness, rather than steering wheel sensors.
GM Super Cruise
Super Cruise was one of the first Level 2 systems on the market and is known for its high performance. Like BlueCruise, it only works on divided highways that GM has mapped and can perform automated lane changes. A driver attention camera ensures eyes stay on the road. However, Super Cruise doesn’t yet offer predictive speed control like Travel Assist.
Tesla Autopilot
Tesla’s famous Autopilot is probably the closest competitor to Travel Assist in terms of functionality. It provides adaptive cruise control, lane keeping, automatic lane changes, and speed limit adjustments. However, Autopilot has been criticized for overpromising its capabilities and having inconsistent performance. Tesla also doesn’t use a driver monitoring camera in most models.
Other Systems
Brands like Nissan, Volvo, Mercedes-Benz and BMW all offer similar partially automated systems. Most are comparable in features and performance to Travel Assist. The biggest differences are in which models they’re available on and how much they cost. Luxury brands tend to restrict the best features to their priciest models.
Overall, Volkswagen’s Travel Assist is one of the most capable and well-executed semi-autonomous systems available from a mainstream brand. It offers similar functionality to luxury rivals at a more affordable price point. The biggest advantage is that it works on a wider variety of roads compared to systems that rely on high-definition maps.
The Future of Travel Assist and Automated Driving
Travel Assist is a big step forward on Volkswagen’s path to self-driving vehicles. But it’s still a long way from full autonomy. In the near future, we can expect to see VW add more capabilities to Travel Assist, such as automatic lane changes and the ability to handle highway interchanges[1].
Further down the line, Volkswagen plans to introduce higher levels of automation that can handle all driving tasks in certain conditions, such as on highways or in urban areas. They’re already testing prototype autonomous vehicles with Argo AI technology. However, these systems will likely be restricted to premium models initially and require special hardware.
Mainstream adoption of fully driverless cars is still many years away. Experts believe that Level 4 autonomous vehicles that can operate without human supervision in most situations won’t be widely available until 2030 or later. Producing them affordably at scale and validating their safety will take significant time and effort.
In the meantime, Level 2 systems like Travel Assist will continue to get more advanced, adding new features and expanding their operating domains. By 2025, we expect most new Volkswagen models to offer some form of partially automated driving as standard equipment.
Conclusion
Volkswagen’s Travel Assist is a cutting-edge Level 2 semi-autonomous driving system that represents the current state-of-the-art in affordable partially automated driving. By combining adaptive cruise control, lane centering and more, it significantly reduces the stress and fatigue of driving on highways and stop-and-go traffic.
While not fully self-driving, Travel Assist is one of the most capable and well-executed driver assistance systems available from a mainstream brand. It offers similar functionality to luxury competitors at a lower price point and works on a wider variety of roads.
If you’re shopping for a new Volkswagen, Travel Assist is definitely a feature worth considering – especially if you frequently take long highway trips. It could just be the thing that makes driving fun and relaxing again.
