The BMW Parking Assistant is another comfort-enhancing driver assistance system from BMW ConnectedDrive to be included in the new BMW 3-Series Sedan. The new system helps the driver to manoeuvre safely and comfortably into parking spaces positioned parallel to the direction of travel. BMW Parking Assistant uses ultrasound sensors integrated into the side indicator surrounds to help the driver search for suitable parking spaces. With the car travelling at no more than 36 km/h (22 mph), these sensors permanently measure the length and breadth of parking spaces at the edge of the road and on roadside verges. BMW Parking Assistant searches for spaces at least 1.20 metres (around 4 ft.) longer than the car itself. With the system activated, the driver is alerted to suitable spaces as he passes them. When the system is switched off, this measuring process takes place in the background; only when the driver draws to a halt and engages reverse gear is the parking space flagged up on the on-board monitor using a suitable symbol. In both cases, drivers can confirm they want to use BMW Parking Assistant with a push of the iDrive Controller. During the parking process all they have to do is operate the accelerator and brake pedal and keep an eye on the area around the car; the Parking Assistant takes care of the steering wheel movements required to carry out a precise reverse parking manoeuvre. Drivers are given instructions to guide them through the parking process. Audible and visual alerts from PDC, the rear view camera or the newly introduced Surround View system help to maintain the required distance to other vehicles or obstacles in the chosen parking space.
