Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
As shown in drawings, the utility model comprises spacing sensor 1, ccd sensor 2, vehicle body 3, wheel 4, car speed sensor 5, wheel hub motor 6, bridge rectifier circuit 7, measurement and control unit 8, front axle 9, rear axle 10, spacing sensor 1 is fixedly mounted on the front portion of vehicle body 3, ccd sensor 2 is fixedly mounted on the surrounding of vehicle body 3 respectively, each four of car speed sensor 5, wheel hub motor 6, bridge rectifier circuit 7, be fixedly mounted on four wheels 4 respectively, four wheels 4 are fixedly mounted in front axle 9 and rear axle 10 respectively; Spacing sensor 1, ccd sensor 2, car speed sensor 5, bridge rectifier circuit 7 are electrically connected with measurement and control unit 8.The vehicle speed signal of spacing sensor 1, ccd sensor 2, car speed sensor 5 respectively collection vehicle and the relative spacing of front vehicles, the graphicinformation of vehicle periphery and four wheels, and various signal is passed to measurement and control unit 8, by measurement and control unit 8 to sending control signal after the signal analysis collected, judgement and process to four bridge rectifier circuits 7, four bridge rectifier circuits 7 drive four wheel hub motors 6 respectively, to control the rotating speed of wheel hub motor 6, wheel hub motor 6 acts on vehicle, thus controls the speed speed of a motor vehicle traveling according to the rules of vehicle.
Respectively each module is described further below.
Measurement and control unit comprises data acquisition module and control module.Data acquisition module comprises three class data acquisition session: (1) distance acquisition tasks.Utilizing the spacing sensor 1 being arranged on vehicle front to obtain accurate range information, is exactly specifically obtain body structure and the distance of front truck rear end and the range information apart from other obstacle, for reporting to the police and control.(2) image acquisition task.Utilize the ccd sensor 2 being arranged on vehicle body surrounding to gather graphicinformation, the image information display of collection in man-machine interface, for the situation outside car in chaufeur real-time monitoring vehicle automatic cruising process.(3) speed data collection task.Utilize the car speed sensor 5 be arranged on wheel 4 to gather speed information, for control.
In control module using notebook PC as device analysis, process the controller of various information, its receives the data that data acquisition module is passed back, carries out merging and calculates the state parameter of needs, sending signal to control the rotating speed of wheel hub motor 6.Specific tasks are: (1), when relative spacing is less than minimum limit value, vehicle stops, and wheel hub motor 6 rotating speed is zero; (2) when the value of relative spacing is greater than threshold limit value, wheel hub motor 6 rotating speed raises, vehicle acceleration, can travel according to the constant vehicle speed of chaufeur setting; (3) when the value of relative spacing is between threshold limit value and minimum limit value, wheel hub motor 6 rotating speed declines, car retardation.
The display interface of human-computer interaction module and the interface of main program are all the display interfaces of computing machine, and its Data Source is spacing sensor 1, ccd sensor 2 and car speed sensor 5.In order to the potential safety hazard preventing sensor flase drop from bringing, the state outside car can be informed chaufeur by Vehicular display device in real time, carves where necessary do suitable interference to driving for chaufeur, strengthens the safety of automatic cruising device.
Control implementation process is as follows:
After being arranged on by whole device on wheel hub motor electronlmobil, be energized to each equipment, enter notebook PC landing program interface, user inputs username and password.Redirect automatically after program test information is correct, the main program of access to plant, clicks start button, plant running.Data acquisition module now in measurement and control unit 8 is started working, and the picture signal collected is passed to data acquisition module by ccd sensor 2, and the data collected show by data acquisition module on front panel, for chaufeur reference.Signal is passed to data acquisition module after collecting the tach signal of wheel by car speed sensor 5, and data acquisition module obtains the numerical value of the speed of a motor vehicle after processing the signal gathered, and shows on front panel.Spacing sensor 1 obtains the distance of Current vehicle distance front vehicles and other obstacle, and data are passed to data acquisition module, the distance value that data acquisition module records by control module and setting value compare, and select which adopts control branch carry out control work according to comparative figure.The algorithm that control module controls rotating speed has been come by three choice structures, and when relative spacing is less than minimum limit value, vehicle stops, and wheel hub motor 6 rotating speed is zero; When the value of relative spacing is greater than threshold limit value, wheel hub motor 6 rotating speed raises, vehicle acceleration, can travel according to the constant vehicle speed of chaufeur setting; When the value of relative spacing is between threshold limit value and minimum limit value, wheel hub motor 6 rotating speed declines, car retardation.Thus the automatic control realized the wheel hub motor electronlmobil speed of a motor vehicle.
