ESP + Trailer Stabilisation
The Touareg is the first Volkswagen that can be supplied with trailer stabilisation
An ESP software extension makes driving with trailers safer
The electronic stabilisation program has revolutionised active safety in the automobile. However, the technical evolution of ESP is anything but over. Especially the software for control of the ESP provides astonishing potential. The best example: ESP + trailer stabilisation. This is a pure software extension of ESP without an additional sensor system.
Initially, Volkswagen will be deploying the ESP + trailer stabilisation for classical towing vehicles such as the Touareg: the system makes most sense here due to relatively frequent trailer journeys and high trailer loads (Touareg: 3500 kilos, braked). At a later date, trailer stabilisation will also be offered for the Multivan.
Although the Touareg in particular, with its very balanced chassis, the optional or standard (V10 TDI) air suspension and of course four-wheel drive, enable extremely safe operation with a trailer, vehicle combinations can of course be subject to body roll - for example due to strong side winds, improper loading, lane grooves or evasive manoeuvres. Here, even experienced drivers are frequently out of their depth.
With the trailer stabilisation of the Touareg, rolling trailers are detected (via the ESP control unit) even as they start to roll by the characteristic vibrations initiated in the towing vehicle. The system excludes incorrect interventions by means of a comprehensive plausibility check of all ESP signals. In the specific emergency situation, the vehicle combination is decelerated via the ESP by braking the towing vehicle at all wheels and reducing the engine torque until the body roll has been eliminated.
As this is targeted braking, the brake lights are activated automatically - even if the brake pedal is not pressed.
Right to the Heart: ESP +
