Abstract
The utility model discloses a device for identifying a speed reducing prediction behavior before a corner. The device comprises a vehicle sensor, a first infrared coil sensor, a second infrared coil sensor, a digital camera, a singlechip and a buzzer, wherein the vehicle sensor, the first infrared coil sensor, the second infrared coil sensor and the digital camera are connected with an input end of the singlechip; and the buzzer is connected to an output end of the singlechip. According to the device, images of the front road relatively far away from a vehicle are acquired by the digital camera, the curvature of the current road is calculated, the safe running speed in the corner is calculated by combining parameters of the vehicle, and the safe driving speed is compared with the speed of the vehicle; and the infrared coil sensors are arranged at the front ends of an accelerator pedal and a braking pedal, and whether a foot of a driver leaves the accelerator pedal and steps on the braking pedal, and the driver prepares to brake so as to pass by the corner in a mode of reducing the running speed can be judged, so that the driver who does not prepare to brake is warned, and a phenomenon that traffic accidents happen can be effectively avoided.
Description
Technical field
The utility model relates to the traffic safety field, is specifically related to chaufeur deceleration anticipation behavior means of identification before a kind of bend.
Background technology
Along with the development of science and technology and improving constantly of people's living standard, it is more and more universal that automobile becomes, and simultaneously, the speed of operation of automobile is also more and more higher.In most cases, chaufeur is the meeting Reduced Speed Now before entering bend, but when making false judgment when driver tired driving or to condition of road surface, can enter bend with the higher speed of a motor vehicle, perhaps just carry out emergency braking at once in the time bend will being entered, these processing eases cause that vehicle breaks away, and perhaps knock into the back and cause traffic accident, thereby causing huge property damage and personal casualty.At present, bend overspeed warning device has been arranged, but only be aimed at the speed of a motor vehicle and judge whether and not break away by bend smoothly, entered whether braking anticipation None-identified is arranged before curved for chaufeur.Have correlative study to show, a lot of accidents are not that the speed of a motor vehicle can not be excessively curved safely, but due to chaufeur enter curved before braking prepare to occur.Bend, especially small radius, combination highway section, curved slope were exactly the highway section of Frequent Accidents originally, and this just requires chaufeur that the preparation of braking deceleration is just arranged in advance.
Summary of the invention
For the deficiency that prior art exists, the purpose of this utility model is, provides a kind of bend front chaufeur deceleration anticipation behavior means of identification, can reduce to lack the braking anticipation due to chaufeur when entering bend, and the accident that directly or indirectly causes.
In order to realize above-mentioned task, the utility model adopts following technical scheme to be achieved:
Chaufeur deceleration anticipation behavior means of identification before a kind of bend, comprise car speed sensor, the first infrared ray coil sensor, the second infrared ray coil sensor, digital camera, micro controller system and buzzer phone, car speed sensor, the first infrared ray coil sensor, the second infrared ray coil sensor and digital camera are connected with the input end of micro controller system, and the mouth of micro controller system is connected with buzzer phone.
The utility model also has following technical characterstic:
Described micro controller system adopts Freescale S12 model micro controller system.
The utility model is by installing digital camera on vehicle, by digital camera collection vehicle road ahead image relatively far away, and lane mark is carried out curve fitting, calculate the curvature of current road, in conjunction with going out safe negotiation of bends speed from the car calculation of parameter, and with compare from the car speed of a motor vehicle.Then judge by the infrared ray coil sensor that is arranged on Das Gaspedal front end and brake pedal front end whether the pin of chaufeur moves lower Das Gaspedal, moving brake pedal prepares to take braking curved to slow down, the chaufeur of not braking preparation is reminded, can effectively be reduced the generation of relevant traffic accident.
Description of drawings
Fig. 1 is annexation schematic diagram of the present utility model.
Below in conjunction with drawings and Examples, particular content of the present utility model is described in more detail.
The specific embodiment
Below provide specific embodiment of the utility model, need to prove that the utility model is not limited to following specific embodiment, all equivalents of doing on present techniques scheme basis all fall into protection domain of the present utility model.
Defer to technique scheme, as shown in Figure 1, chaufeur deceleration anticipation behavior means of identification before a kind of bend, comprise car speed sensor, the first infrared ray coil sensor, the second infrared ray coil sensor, digital camera, micro controller system and buzzer phone, car speed sensor, the first infrared ray coil sensor, the second infrared ray coil sensor and digital camera are connected with the input end of micro controller system, and the mouth of micro controller system is connected with buzzer phone.Described micro controller system adopts Freescale S12 model micro controller system.Wherein car speed sensor is arranged on the transmission output shaft of automobile, digital camera is arranged on the vehicle cab dead ahead, the first infrared ray coil sensor is arranged on Das Gaspedal the place ahead, the second infrared ray coil sensor is arranged on brake pedal the place ahead, whether the pin that is used for gathering chaufeur is in Ackermann steer angle generation anticipation behavior, and buzzer phone is arranged in operator's compartment.
When the utility model uses, car speed sensor 1 Real-time Collection is from the speed of a motor vehicle of car, digital camera 2 Real-time Collection road images are delivered to micro controller system 5, micro controller system 5 therefrom identifies lane mark, thereby obtain the radius of curvature of road by curve, and according to going out vehicle safety by the speed limit of bend from the car calculation of parameter, with the real-time speed of a motor vehicle with calculate speed limit and compare; Then judge by the infrared ray coil sensor 3 before Das Gaspedal whether the pin of chaufeur moves down from Das Gaspedal, judge by the infrared ray coil sensor before brake pedal whether the pin of chaufeur moves upper brake pedal.Cross the curved speed of a motor vehicle if surpass safety from the car speed of a motor vehicle, the pin of chaufeur does not move down and moves upper brake pedal from Das Gaspedal and prepares to take braking deceleration, pass through bend, the Single-chip Controlling buzzer phone sounds the alarm, the prompting chaufeur notices that Reduced Speed Now passes through bend, avoids sailing at a high speed the generation that bend causes the accident.
Claims (2)
1. chaufeur deceleration anticipation behavior means of identification before a bend, it is characterized in that, comprise car speed sensor, the first infrared ray coil sensor, the second infrared ray coil sensor, digital camera, micro controller system and buzzer phone, car speed sensor, the first infrared ray coil sensor, the second infrared ray coil sensor and digital camera are connected with the input end of micro controller system, and the mouth of micro controller system is connected with buzzer phone.
2. chaufeur deceleration anticipation behavior means of identification before bend as claimed in claim 1, is characterized in that, described micro controller system adopts Freescale S12 model micro controller system.
