The automobile automatic speed limiting system comprises a processor, wherein the processor is connected with a camera unit, an image module, a vehicle speed sensor and an automobile communication bus, and the automobile communication bus is connected with an engine electronic control unit.
Description
Technical field
The utility model relates to the automobile supplementary security system, relates in particular to a kind ofly to carry out the control system of automatic speed-limiting for automobile according to stated-speed sign.
Background technology
It is a kind of major cause that causes traffic accident that overspeed of vehicle travels, and the speed of a motor vehicle has surpassed the speed that safety traffic law, rules and regulations or road traffic environment allow, and the difficulty of the higher control vehicle of the speed of a motor vehicle is larger, very easily causes traffic accident.Therefore, steerman will strictly observe the speed limit regulation of laws and regulations in driving, keep the moving velocity of safety, judges road conditions and processes dangerous situation to ensure time enough.Chinese patent CN201035725Y, open day is that on 03 12nd, 2008 patent documentation discloses a kind of vehicle safety drive wireless controller, it comprises on the channel wireless radio multi receiver that is installed in the automobile and the electric pole that is installed in the speed-limit road section side or the transmitting set assembly of the different speed-limit road section signals of representative on other support, the command signal that the transmitting set assembly of the different speed-limit road section signals of channel wireless radio multi receiver reception representative on the automobile sends, the power supply of each main circuit board on the matching used combined type automobile Tachographs automaticallyes switch, in case the moving velocity of automobile surpasses the speed limit of this highway section regulation, the combined type automobile Tachographs will send phonetic warning, and reminding driver is not driven over the speed limit.The shortcoming of its device is: the equipment such as Tachographs need to be installed in highway section and Che Nei install the wireless chips that transmits restricting signal, car, and engineering is large, complex structure, install and use convenient not.
Summary of the invention
The utility model main purpose is to provide a kind of Car Automatic Speed Limit system, and its satisfy the need stated-speed sign in upper and roadside is collected, identified, and the volitional check road speed is simple in structure, easy to use.
The utility model is mainly solved by following technical proposals for the prior art problem, a kind of Car Automatic Speed Limit system, one treater connects communication bus on an image unit, an image module, car speed sensor and the car, communication bus connecting engine electronic control unit on the car.
Treater is by image unit picked-up vehicle front image, use image module that pickup image is carried out identifying processing, find out stated-speed sign and speed limit, treater detects the speed of a motor vehicle by car speed sensor afterwards, and contrast with speed limit, when vehicle speed value during greater than speed limit, the notice engine electronic control unit reduces engine speed until reduce the speed of a motor vehicle in allowed band.
As preferably, the field range of image unit comprises road the place ahead and roadside.In order to observe the stated-speed sign that is arranged on road top, roadside.
As preferably, image unit is wide-angle camera.Same camera can absorb the image in road top and roadside when using wide-angle camera, reduces the installation quantity of camera.
As preferably, wide-angle camera is the infrared wide-angle camera, is convenient to absorb night stated-speed sign.
As preferably, image module comprises image capture module, formwork module, image processing module and picture recognition module.Wherein, image capture module is responsible for the sequence chart picture frame of acquisition camera and is stored, for after-treatment; Storage ring shape traffic indication map and various stated-speed sign figure with speed limit in the formwork module; Image processing module is responsible for the picture frame that gathers is carried out transform domain processing and gray scale, contrast ratio enhancing and image segmentation, and image segmentation is to find out the ring shape traffic indication map according to formwork module from the picture frame of picked-up; Picture recognition module is mated calculating according to formwork module to the ring shape traffic indication map of finding out, and can learn the speed limit in this highway section if the match is successful.
As preferably, treater connects a voice cue module.After detecting speed limit, carry out simultaneously speech play and inform chaufeur this highway section speed limit and speed limit.
As preferably, treater connects a function button.Utilize this function button, when running to non-speed-limit road section, remove the speed limit to driving engine.
The beneficial effect that the utility model brings is, stated-speed sign by camera head road pavement and roadside is automatically collected, is identified, the volitional check road speed, its device structure is simple, easy to use, vehicle is travelled in strict accordance with the speed that safety traffic law, rules and regulations or road traffic environment allow, significantly increase travel safety.
Description of drawings
Fig. 1 is a kind of functional block diagram of the present utility model.
Among the figure: the 1st, image unit, the 2nd, image module, the 21st, image capture module, the 22nd, image processing module, the 23rd, picture recognition module, the 24th, formwork module, the 3rd, car speed sensor, the 4th, voice cue module, the 5th, treater, the 6th, communication bus, the 7th, engine electronic control unit, K1 are function buttons.
The specific embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment: as shown in Figure 1, the utility model is a kind of Car Automatic Speed Limit system, treater 5 connects respectively communication bus 6 on image unit 1, image capture module 21, image processing module 22, picture recognition module 23, formwork module 24, car speed sensor 3, voice cue module 4 and the car, and engine electronic control unit 7 is connected on the communication bus 6.Wherein image unit 1 is the infrared wide-angle camera, is installed on the vehicle front bumper, and angular field of view comprises road top and road on both sides of the road, can photograph traffic sign on the road and the traffic sign in roadside; In formwork module 24, deposit a ring shape traffic indication map, and speed limit is that several stated-speed signs figure such as 5,10,15,20,30,40,50,60,70,80,90,100,110,120 are as template.
When vehicle begins to travel, treater 5 is started working, image capture module 21 begins to gather the sequence chart picture frame of infrared wide-angle camera and is stored in the memory device of treater 5, the picture frame of 22 pairs of storages of image processing module carries out transform domain to be processed and the processing such as strengthens, cuts apart, find out the characteristic image that contains the ring shape sign, picture recognition module 23 is mated calculating according to the stated-speed sign template to characteristic image, output speed limit when the match is successful; Treater 5 gathers the real-time speed of a motor vehicle by car speed sensor 3, and with output speed limit compare, if the speed of a motor vehicle is greater than the output speed limit in real time, reduce engine speed by communication bus 6 notice engine electronic control units 7, until so that the real-time not super speed limit of the speed of a motor vehicle, and send the speed limit voice suggestion by voice cue module 4 to chaufeur simultaneously.Chaufeur can be by function button K1 at non-speed-limit road section or when not needing speed limit, and notice engine electronic control unit 7 is removed the rotating speeds restriction.
So the utlity model has following characteristics: the stated-speed sign by the round-the-clock road pavement of infrared wide-angle camera and roadside is automatically collected, is identified, the volitional check road speed, device structure is simple, easy to use, vehicle is travelled in strict accordance with the speed that safety traffic law, rules and regulations or road traffic environment allow, significantly increase travel safety.
