Abstract
The invention relates to an active anti-collision method based on an internet of vehicles. A short-distance communication module of a car-mounted terminal main body and other car-mounted terminals staying in a valid communication range of the short-distance communication module form a mobile ad hoc network; a global positioning system (GPS) module of each car-mounted terminal collects position information, speed and running route information of a car, an acceleration sensor collects acceleration of the car, all collected information is transmitted to a main control unit to form running data to be broadcasted in the mobile ad hoc network through the short-distance communication module; and when one car-mounted terminal enters the optimum communication range of the short-distance communication module of the car-mounted terminal main body, the car-mounted terminal main body defines the car-mounted terminal as a target vehicle, a binocular camera is adopted to collect three-dimensional information of the target vehicle, the safety distance between the two vehicles is calculated according to the received running data broadcasted by the target vehicle and the three-dimensional information of the target vehicle collected by the local terminal, whether a danger exists or not is judged according to the safety distance, a brake alarm module is actuated when abnormality occurs, and the intelligent active protection of the car can be realized.
Description
Technical field
The present invention relates to the car networking technology, specifically be meant a kind of active avoiding collision based on the car networking.
Background technology
Current; The car networking all obtains fast development in technology with popularizing, but the research of existing car networking technology focuses mostly on the location and Image Acquisition of remote monitoring center and car-mounted terminal; For the car owner; The most basic is life security, so, remain exploitation with perfect to the crashproof technical scheme of mobile unit active in the car networking.
Summary of the invention
The objective of the invention is to overcome above-mentioned weak point of the prior art; A kind of active avoiding collision based on the car networking is provided; Be in the short-range communication module of various car-mounted terminals through separately in the short-range communication module efficient communication scope and realize communicating with one another and move self-service network to form, when a certain car-mounted terminal got into the optimal communication scope of car-mounted terminal main body short-range communication module, the car-mounted terminal main body was defined as target vehicle; Calculate the safe distance between the vehicle; Judge whether dangerously according to safe distance, occur activating the braking alarm module when unusual, realized that the intelligence of driving is initiatively crashproof.
The object of the invention realizes that through following technical scheme the active avoiding collision based on the car networking specifically comprises:
The short-range communication module of car-mounted terminal main body is formed mobile self-grouping network with other car-mounted terminals of the efficient communication scope that is positioned at its short-range communication module; Information, this vehicle speed and traffic route information are put in this parking stall of GPS module collection of each car-mounted terminal; Acceleration transducer is gathered this car acceleration; Each information reaches main control unit and forms the driving data, broadcasts in mobile self-grouping network through short-range communication module;
When a certain car-mounted terminal gets into the optimal communication scope of car-mounted terminal main body short-range communication module; The car-mounted terminal main body is defined as target vehicle; Start the binocular camera shooting head and gather the 3 D stereo information of target vehicle; Safe distance between the 3 D stereo information calculations vehicle of the target vehicle of gathering according to the driving data and the local terminal of the broadcasting of the target vehicle that received judges whether dangerously according to safe distance, the braking alarm module occurs activating when unusual.
The present invention compares that prior art has the following advantages and beneficial effect: the present invention provides a kind of active avoiding collision based on the car networking; Being in the short-range communication module of various car-mounted terminals through separately in the short-range communication module efficient communication scope realizes communicating with one another and moves self-service network to form; When a certain car-mounted terminal gets into the optimal communication scope of car-mounted terminal main body short-range communication module; The car-mounted terminal main body is defined as target vehicle; Calculate the safe distance between the vehicle, judge whether dangerously according to safe distance, the braking alarm module occurs activating when unusual.
