We observe the approach of a Passat estate, it stops, the driver gets
out, slams the door shut and, as he walks away from the car, he aims a
remote control back at it. That car now proceeds to reverse park itself
into the available space, it then independently cuts the engine and
activates the door locks. End of performance. In reality, there is
nothing at all fantastical about this demonstration. The live
performance by Volkswagen can be viewed at this year’s Hanover Fair (21
to 25 April), where the carmaker is premiering its “Park Assist
Vision”, a system with the ability to guide a Passat prototype with
absolute precision into a perpendicular parking space, i.e. the kind
available on parking lots and in underground car parks. These parking
spaces are often too narrow to allow drivers and passengers to get in
and out of the car comfortably. In the not too distant future, “Park
Assist Vision” will put an end to that.
Having already launched a semi-automatic park-steering system, the
"Park Assist", in its Touran, Tiguan, Passat and Passat estate to help
drivers parallel park, Volkswagen is now presenting a concept system at
the Hanover Fair which is capable of perpendicular parking – and of
doing so fully automatically. The only thing the driver needs to do is
select an available space on the monitor of the navigation system, set
the selection lever of the automatic-drive vehicle (DSG) to "P" and
alight from the car. The driver can, of course, choose to stay in the
vehicle until the vehicle has been manoeuvred into its space.
Two
cameras located in the left and right exterior mirrors are responsible
for gauging the dimensions of the parking space. The video signals are
transmitted to a 2-GHz high-performance computer which then analyses
them and sends commands to the steering and drive systems. If the
driver has himself initiated the parking manoeuvre, the "Park Assist
Vision" will reverse the vehicle into the parking space in accordance
with the previously computed course and using electromechanical power
steering, the electronic parking brake, DSG and the engine power
produced by the idling mixture. Two additional cameras at the front and
rear of the vehicle as well as the system’s ultrasound
sensors monitor the operation and will stop the vehicle if necessary.
The driver may also interrupt the manoeuvre at any time using the
remote control.
This new driver assistance system is
still in the trial phase of development, and a date has not yet been
set for introduction of the system to series production.
