Park assist steering 2.0

Design and function

The new park assist steering 2.0 is used in the 2nd

generation Touran initially, followed by the Sharan

2011. It represents a considerable improvement over

the already well established 1st generation park assist

steering version 1.0, as well as the further developed

1.5 version.

As the first parking system of its kind, the 2nd

generation park assist steering system features active

brake intervention to reduce any potential damage

from parking. The system still supports exiting from

parallel parking spaces as before.

This self-study programme presents the main new

features of the new park assist steering system

compared with the earlier generation.

The content covers the system components and the

mode of operation.

With this new semi-automatic parking system, parking

in bays perpendicular to the road and parking in

even tighter parking spaces parallel to the road (kerb-

side parking) have been made possible. In both

instances, parking can be carried out in several

stages.

Introduction

Overview

The park assist steering system was first introduced with the Touran 2007. Park assist steering supports the driver

when parking. It turns the steering wheel automatically. All the driver has to do is press the accelerator, engage the

relevant gear and press the brake. The driver has the power to override the system at any time and end the park

assist steering function.

With the park assist steering version 2.0, initially first used in the Touran and Sharan 2011, it is now possible to park

in tighter parallel spaces. As well as the new perpendicular parking function, the system also offers new functions

for parallel parking, such as full or partial parking on kerb stones, parking between other obstacles (trees, bushes

or motorbikes) and also parking on bends. The system still supports exiting from parallel parking spaces.

The park assist steering functions comprise

the parking aid, also referred to as park distance control PDC.

Also available without park assist steering, but has to be separately activated in a vehicle with park assist

steering (e.g. when parking forwards).

the steering function for the active parking process.

S494_002

The level of luxury offered by park assist steering version 2.0 must not mislead the driver into a

hazardous situation. The system cannot substitute the driver’s concentration.

The driver must maintain control and an overview of the parking process and must not solely rely on the

park assist steering.

System comparison

The use of 6 sensors at the front and rear respectively, an enhanced system network and further developed

software facilitate the functions of park assist steering version 2.0.
