Abstract

A system for detection of braking of a vehicle may include a device provided in a first vehicle. The device may be in communication with a detector mounted to the first vehicle to monitor an area in front of the first vehicle. The detector may detect light emitted by the rear lights of a second vehicle when the second vehicle is ahead of the first vehicle in the monitored area. The device may acquire data from the detector and analyze the acquired data in order to detect an optical signal emitted by the rear lights of the second vehicle. The optical signal may encode information indicative of a braking procedure being performed by the second vehicle. The device may evaluate the detected optical signal in order to derive the information indicative of the braking procedure of the second vehicle.
