Innovative boot access makes life a little easier

BMW ConnectedDrive has come up with another convenience-enhancing feature: the hands-free boot lid opening function - available for the new BMW 3-Series Sedan in conjunction with Comfort Access - is a first in the premium class. Standing behind the car, customers can prompt the boot to open with just a short movement of their foot under the centre of the rear bumper, i.e. without using their hands. The boot then automatically unlocks and swings open by spring force. The vehicle is fitted with sensors placed at different heights in the rear bumper trim, which are able to identify a person standing behind the vehicle. The sensors can identify the foot "command" by monitoring the area of the leg between the shin and the tip of the foot. They then send a signal containing special algorithms to the on-board computer. Access is only authorised, however, if the system simultaneously identifies the Comfort Access control unit (the key), which the person must be carrying with them. The boot lid is then unlocked and raised automatically, without hand contact. Key authorisation provides the safeguard ensuring correct operation at all times.
