Driving with a trailer is a special challenge, even for experienced drivers. Above all, reversing manoeuvres can quickly become complicated and stressful. Volkswagen offers help in precisely these types of situations with Trailer Assist, which simplifies the manoeuvring process considerably. It applies regardless of whether the task involves positioning a horse trailer in front of the right horse stall at an equestrian event, or positioning a caravan at a campsite. The system handles the steering while the driver accelerates and brakes the car-trailer combination. The driving direction is adjusted using the mirror adjustment joystick. Easily, quickly and safely.

The innovative, optionally available Trailer Assist can be activated at the push of a button to enable even inexperienced trailer drivers to reverse a trailer quickly and safely. The mirror adjustment switch, which is then used as a joystick, lets the driver variably set the desired driving direction for the car-trailer combination and modify it at any time. The actual driving angle and the angle set by the driver are visualised in the instrument cluster. The system automatically controls the electromechanical power steering, while all the driver needs to do is accelerate and brake.
When the trailer is pointing in the correct direction, the driver simply presses the mirror adjustment switch towards the rear, and the trailer then appears to effortlessly pull the vehicle behind it along a straight line. This relieves all of the anxiety of straight-line reversing with a trailer, even over long stretches.
Playing a crucial role in the manoeuvring process is the camera technology that is integrated into the vehicle. It enables Trailer Assist to perform automatic lateral guidance of the car-trailer combination. The process is based on image processing algorithms using data from the rear-view camera system, which monitors and analyses the articulation angle between the car and the trailer. Optical measurement of the articulation angle is used to compute the required steering angle – regardless of the type of trailer model or draw bar used.
The system is another piece of pioneering work by the technical developers at Volkswagen, whose goal was to make complicated parking and manoeuvring actions easier and safer. Anyone who tows a trailer will appreciate this help very quickly if they need to make precise movements while manoeuvring trailers in a tight space, e.g. garden waste trailers, motorcycle trailers or caravans. It ensures relaxed transport of anything that is being towed behind the trailer coupling.
