Greater safety and convenience
Travel Assist and Emergency Assist increase safety.The new T-Roc is based on the MQB evo – the latest evolutionary stage of the modular transverse matrix. This is accompanied by a new range of assist and convenience systems in the T-Roc class. In fact, thanks to the MQB evo, the second generation of the T-Roc has technologies on board that are also used in larger Volkswagen SUV models, such as the Tiguan and Tayron. As currently the latest MQB-evo model series, the T-Roc benefits from all the hardware and software developments from this innovative modular system. This includes the next development stage of Travel Assist, which now not only supports automatic lane changes, but also reacts with even more foresight and more smoothly to upcoming speed limits or the lifting of speed limits. Another important safety system is Emergency Assist, which, within the system limits, can automatically steer the new T-Roc to the nearside edge of the road and bring it to a standstill in an emergency – particularly if the driver is no longer able to intervene due to health problems.

Exit warning system can protect cyclists. A new feature on board the T-Roc is the exit warning system equipped as standard, which can warn occupants before opening the doors if cars or bicycles are approaching from behind. This system was introduced in a similar form for the first time with the ID.7. Particularly in inner-city traffic, the exit warning system can help to prevent accidents that are dangerous for cyclists – caused by the sudden opening of the vehicle door. For the first time, the T-Roc is also equipped with systems such as Park Assist Pro, which enables trained and thus fully automatic parking over distances of up to 50 metres using the memory function, while the remote function allows a smartphone to be used to drive the vehicle in and out of parking spaces.

Adaptive chassis control DCC optimises comfort. The comfort and dynamic characteristics of the 110 kW T-Roc versions can be customised with the optional adaptive chassis control DCC. This is linked to the driving profile selection provided as standard. If the driver changes the driving profile from Comfort to Sport, for example, the tuning of the electronically controlled dampers changes to a significantly more dynamic setup. In the Individual profile, the driver can also set all adjustable parameters of the T-Roc individually. In addition to the DCC chassis, this includes the air conditioning system, steering, Adaptive Cruise Control ACC and the response time of the drive.

Assisted lane changing by Travel Assist

Important assist and chassis systems in detail
Travel Assist. Travel Assist is available in conjunction with the optional IQ.DRIVE technology package in the T-Roc. Thanks to a new software version and enhanced sensors, Travel Assist now reacts with even more smoothly and with enhanced functional reliability. The system’s background: Travel Assist enables the vehicle to drive with assisted longitudinal and lateral or lane centre guidance. In other words, The T-Roc can automatically steer, brake and acceleratewithin the speed window of the speed limits set or detected via Dynamic Road Sign Display and navigation software. However, the driver must be able to intervene at all times and therefore be touching the capacitive surfaces on the steering wheel as a prerequisite for the function. New in the T-Roc: in conjunction with the Side Assist and Lane Assist functions on board as standard, the system now enables assisted lane changes on multi-lane motorways from approx. 68 km/h. When Travel Assist is active, it predictively integrates upcoming parameters, such as corners, roundabouts and junctions, into vehicle control and the displays. For instance, if there is a corner ahead and the set speed is too high for taking the corner, the system shows the message ‘Corner ahead’ along with a recommended speed. All of this now takes place even more precisely for several reasons. Firstly, the system can use swarm data through V2X technology. If data transmitted by other vehicles in the vicinity is available, the Travel Assist system, for example, only relies on one detected road lane marking to keep the vehicle in lane. The same effect occurs as soon as the T-Roc’s front camera detects a vehicle in front: In this case too, one road lane marking is sufficient for lane guidance, as the SUV use the vehicle in front as orientation.

The latest Travel Assist system offers more balanced control. Thanks to the additional integration of swarm data and the latest software, the latest generation of Travel Assist offers particularly balanced vehicle control. An example: in the past, when a speed limit was lifted, the system was only able to accelerate once the vehicle had driven past the corresponding road sign. Now the T-Roc responds like a driver who recognises the lifting of the speed limit ahead and slowly initiates acceleration. This anticipatory response of Travel Assist means that the driver uses the assist system intuitively and therefore more frequently. Last but not least, Travel Assist can protect the people on board the T-Roc and other road users: if the driver is not responsive, it uses the emergency function to automatically steer the SUV onto the hard shoulder while sounding the horn and flashing the hazard warning lights and stops the vehicle there.

T-Roc with Emergency Assist

T-Roc with proactive occupant protection system

T-Roc with Park Assist Plus

Emergency Assist. Like Travel Assist, the Emergency Assist safety system is also part of the IQ.DRIVE technology package. The system is permanently active. As soon as the T-Roc’s sensors detect that the driver is not steering, braking or accelerating, the system initially initiates a warning for the driver in various escalation stages and then an emergency stop. The T-Roc’s hazard warning lights are automatically switched on, and the horn is activated to alert the surroundings to the hazardous situation. Finally, Emergency Assist can brake the SUV continuously to a standstill. On multi-lane roads, the T-Roc is simultaneously and automatically moved to the far nearside lane and, if possible, to the hard shoulder. During this time, the vehicle’s surroundings are monitored to prevent rear-end collisions. After the Volkswagen comes to a standstill, an emergency call is automatically initiated using the Emergency Call Service to ensure prompt medical care for the driver.

Proactive occupant protection system. The proactive occupant protection system also integrated in the IQ.DRIVE technology package detects a potential accident situation. In this case, the seat belts for the driver and front passenger are automatically pre-tensioned in the T-Roc; the resulting fixation of the upper body optimises the protection provided by the airbag systems. Depending on the driving situation – for example, in the event of severe oversteering or understeering with ESC intervention – the side windows and sliding sunroof are also closed down to a residual gap in order to also optimise the effect of the airbags. Volkswagen thus also achieves the best possible occupant protection in the more compact vehicle classes.

Area View plus rear view camera system. The optional IQ.DRIVE technology package includes the Area View system new in the T-Roc in conjunction with the rear view camera system familiar from the predecessor. With IQ.DRIVE, the system additionally accesses a camera in each of the exterior mirrors and a camera at the front and merges the sensor data to calculate a 360-degree bird’s-eye view – known as Area View. Here, the SUV is shown from above so that kerbs and parking space markings, for example, can be optimally recognised. It is even possible to look round corners within the scope of what is technically feasible.

Park Assist Plus and Park Assist Pro. The basic function of Park Assist Plus, which comes as standard in the T-Roc Style and T-Roc R-Line, is a system that is also familiar from other Volkswagen vehicles. It allows assisted driving into parallel or bay parking spaces. Assisted driving out of parallel parking spaces is equally possible. The T-Roc takes over control of acceleration, braking and steering for this purpose. New for T-Roc drivers is the Parking package with memory function for Park Assist and Park Assist Pro with remote function also integrated in the package. Using the memory function, the T-Roc records the last 50 metres driven and thus the parking situation. The parking manoeuvre can be stored when the SUV has come to a stop. When the T-Roc reaches this position again, it automatically offers to take over parking. Independent driving out of a parking space is also possible. Up to five parking manoeuvres can be stored. As described above, remote parking is also new: using Park Assist Pro and an app of the same name, it is now possible to drive the T-Roc into and out of parking spaces remotely from outside the vehicle using a smartphone. This is a perfect example of top-down technology because this remote parking function was possible for the first time in the luxury-class Touareg SUV. Now this system has also been introduced in Volkswagen’s large-volume SUV models, the Tayron, Tiguan and T-Roc.

Exit warning system. As an extension of the Side Assist lane change system, the standard-equipment exit warning system used for the first time in the T-Roc can –within the system limits – prevent one of the doors from being opened if a vehicle approaches from behind. In this case, the system briefly issues an acoustic and visual warning about opening the door(s) in question. The exit warning system is an assist system that not only protects the occupants of the T-Roc – it was also designed above all to prevent the often dangerous accidents involving cyclists, who could be knocked over due to the sudden opening of the doors.
