Device for detecting fall of remote control utilized to remotely control centralized locking device to lock or unlock side door of car, has control unit triggering emission of warning signal warning user of remote control

摘要

The device (D) has a detection unit (MD) detecting fall of a remote control (TC), where the detection unit generates a warning signal in case of detection of fall. A control unit (MC) triggers emission of the warning signal warning a user of the remote control, by a warning unit (ES) comprised by the remote control, in case of reception of the warning signal. The detection unit is in a form of piezoelectric transducer circuit.
