VW's Park Assist Vision will be a breeze; all it takes is a touch of a button.

Car park spaces that are so narrow you can't open the doors will be a piece of cake in the future.

Volkswagen has unveiled a concept remote-control system that parks the car after the driver and passengers have hopped out.

The Park Assist Vision concept was launched at the Hanover Fair this week in a VW Passat.

How to get the car out of the tight space has not yet been resolved.

Toyota and Lexus have led the way in bringing self-parking cars to the market. However, these are designed to be used in street-side parallel parks and require the driver to remain in the car and apply the brake to control the speed of the procedure, but not steer.

The VW system works in perpendicular car park situations, using cameras, ultrasound sensors and satellite navigation, with no driver input.

The driver only has to press the button on a remote control. Once the vehicle has automatically parked, it shuts off the engine, winds up the windows and locks the doors.

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.

The only models available in Australia with self-parking functions are the Lexus 460 and the hybrid LS600h, costing $134,900 and $186,200, respectively.

These technologies are expected to gradually become cheaper and filter down to more affordable models.
