System for vehicle braking detection

摘要

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.

1. A method of detecting braking of a vehicle, the method comprising:
providing a device in a first vehicle, the device being in communication with a detector mounted to the first vehicle; monitoring an area in front of the first vehicle with the detector to detect light emitted by rear lights of a second vehicle when the second vehicle is travelling ahead of the first vehicle and is positioned in the monitored area, the device acquiring data from the detector when light emitted by the rear lights of the second vehicle is detected; analyzing the acquired data with the device to detect an optical signal emitted by the rear lights of the second vehicle which encodes information indicative of a braking procedure performed by the second vehicle, the information indicative of a braking procedure comprising an indication of braking strength; and evaluating the detected optical signal with the device to derive the encoded information indicative of the braking procedure performed by the second vehicle; where analyzing the acquired data comprises:
determining from the acquired data a brightness in at least a first light emitting area and a second light emitting area of the rear lights of the second vehicle; anddetermining a relative brightness between the first and second light emitting areas, wherein the first and second light emitting areas emit light at a same moment in time, and the relative brightness is included in the optical signal.
