Activating a vehicle's own brake lights and/or brakes when brake lights are sensed in front of the vehicle, including responsively to the proximity of, and/or rate of closure with, a forward vehicle

Any presence of brake light emissions of another vehicle to the forward of a subject vehicle is sensed in a color camera and microprocessor system that detects (i) red light(s) illuminations in excess of other colors, that are any of (ii) appropriately sized, (iii) appropriately located, (iv) simultaneously occurring, (v) spaced apart in separation, (vi) substantially horizontal, and/or (vii) of approximately of equal intensity, as would be appropriate to a single brake light, or to a pair of brake lights, as the case may be. The brake lights of the subject vehicle are preferably applied either during (i) the persistence of any detection of the brake light(s) of any other vehicle(s) to the forward, or (ii) normal application of the subject vehicle's own brakes. The forward-sensed rearward-propagated brake light signal is preferably delayed in propagation, limiting any propagation of minor perturbations in traffic. Optional application of the vehicle's own brakes may be conditioned upon (i) proximity to and/or rate of closure with a forward emission source as is preferably determined by angles, and/or upon (ii) rate of closure, speed or deceleration G force of the subject vehicle. The brake light signal, whether simple or sophisticated in either its development and/or presentation, beneficially alerts drivers to the rear of impending or actual slowing, thus deterring rear end collisions and promoting fuel economy.

Automobile autopilot system

The invention discloses an automobile autopilot system comprising an automobile control unit, a positioning system, an information transmit-receive unit and a steering-by-wire system; wherein the automobile control unit is used for recording driving routes by the positioning system, for exchanging information between the automobile autopilot system and urban road monitoring center by the information transmit-receive unit, for correcting road information provided by urban road monitoring center, for recording the movement of steering wheels by the steering-by-wire system, and for correcting steering data by combining the positioning function of the positioning system. When the autopilot function is activated, the automobile control unit is used for automobile automatic piloting control according to road information, traffic report and steering data of a selected section of road. Real-time data interchange between the automobile autopilot system and urban road monitoring center is provided, so that road information can be updated timely; navigation accuracy is increased; traffic violations such as speeding, running red lights are decreased; car accident rate is decreased, and the safety of drivers is ensured in a certain level.

Traffic violation detection method based on video tracking and pattern recognition

The invention discloses a traffic violation detection method based on video tracking and pattern recognition, and belongs to the technical fields of image recognition and pattern recognition. The method comprises the following steps: firstly, defining violation modes, namely defining traffic light stop lines, driving directions, and areas and directions of violation of course change; secondly, monitoring and controlling a camera to shoot video images of intersections; and thirdly, analyzing the video by an embedded system, performing detection and measurement by a pattern recognition method, using the video to track and acquire running tracks of vehicles, using the pattern recognition method to analyze behaviors of any one vehicle according to the running tracks, and immediately shooting the vehicle for recording if one of the following violation behaviors happens: going in wrong directions, violation of full line course change and running of a red light. A detection device used comprises a high-speed camera, a video controller, and a video tracking and pattern recognition device, wherein the video tracking and pattern recognition device comprises a traffic light signal receiving device, a video acquisition and conversion module, a violation setting module, a vehicle detection module, a video tracking module, a violation analysis module, a camera control module and a data wireless transmission module.
