BMW experiment with intelligent haptic car doors
Prototype smart car door detects hazards
Intelligent car door clams up when danger's about
Accidents caused by car doors being opened into the path of oncoming vehicles or cyclists are common in cities. But these incidents could become a thing of the past, if doors that react to potential impacts catch on.
The brainchild of Michael Graf at BMW and Michael Strolz's team at the Technical University of Munich, the "haptic" – technology that gives tactile feedback – doors could cut both road injuries and repair bills, they say.
The current prototype looks like a normal car door, but an extra metal bar runs through its centre and connects to the car's frame between the hinges. In normal mode, the bar moves freely and doesn't affect the door's movement.
