ArvinMeritor has today unveiled its patented Low Energy Release (LER) door latch which it describes as a ‘solution for tomorrow’s vehicle safety and door closure requirements’.
The LER uses proprietary electronics and software controls coupled with a mechanical solution to greatly reduce release efforts without compromising strength or safety. The LER improves passive entry functionality; releases at far higher seal loads; provides silent locking operation; and offers increased resistance against theft tools.

“ArvinMeritor’s original software locking logic means the same latch system can operate under a multitude of different regional and customer specific functional demands across all vehicle platforms,” said Aziz Aghili, vice president and general manager, Aperture Systems, with ArvinMeritor’s Light Vehicle Systems business group. “The LER latch is a market-leading innovation that delivers tremendously improved function and cost for our OEM customer.”
Uniquely, this latch employs a failsafe override mechanism that, in the event of vehicle power failure, allows the latch to revert to fully mechanical operation. The product is considerably smaller and lighter than current designs and contains up to 50 percent fewer parts. The range of application includes side door latches, power locking, electrical release and powered closure, as well as variants for sliding doors, trunks and tailgates.
