Accompanying drawing explanation
Fig. 1 is theory diagram of the present invention;
Fig. 2 is the schematic flow sheet of control method of the present invention.
Embodiment
Below in conjunction with Fig. 1 to Fig. 2, the present invention is described in further detail.
Consult Fig. 1, a kind of synchronous control loop based on car networking, vehicle is furnished with vehicle-mounted end 10, vehicle-mounted end 10 comprises signal gathering unit 11, performance element 12, processing unit 13 and communication unit 14, described signal gathering unit 11 for collection vehicle position, turn to, throttle, brake information export processing unit 13 to, the information and executing car brakeing that performance element 12 exports according to processing unit 13, acceleration, steering operation, the processing unit 13 of two cars realizes the transmission of information by communication unit 14.Native system is applicable to the vehicle of same routes, after rear car is mated with front truck, after directly adopting follow the mode, can carry out automatic Pilot, remove the operation of rear car from, reduce the fatigue strength of driver.Further, according to the difference of road conditions, pairing can be cancelled, drives separately.
More preferably, also comprise server end 20, described communication unit 14 comprises GPRS module or 3G/4G mixed-media network modules mixed-media 141, DSRC module 142, carry out Near Field Communication by DSRC module 142 between two vehicle-mounted ends 10, vehicle-mounted end 10 and server end 20 carry out communication by GPRS module or 3G/4G mixed-media network modules mixed-media 141.In order to the realization to vehicle implementing monitoring and other functions, be provided with server end 20 here.When vehicle travels in high speed, want the vehicle strange with other to match, will know the driving path of other vehicles, whether consistent with the driving path of this car, only when path is consistent, this car could match with it and follow.DSRC is a kind of wireless communication technology efficiently, it can be implemented in territory, specific cell and (is generally tens of rice) to the identification of the moving target under high-speed motion and two-way communication, DSRC module 142 is used to carry out communication between the vehicle after coupling, reliably more convenient.
Further, described signal gathering unit 11 comprises GPS module 111, abs controller 112, gyroscope 113, steering wheel angle sensor 114, brake pedal angular displacement sensor 115, gas pedal angular displacement sensor 116 and radar probe 117.Collecting unit 11 can collect vehicle position information, periphery situation and the operation information to vehicle, and the front vehicle conveniently matched makes identical operation.
Particularly, described performance element 12 comprises clamping device 121, accelerator 122, steering gear 123 and emergency alarm device 124.Performance element 12 is for manipulating rear car, and its manipulation depends on the manipulation of front truck, and when the data that road conditions are complicated or front truck gathers have abnormal, emergency alarm device 124 performs warning, reminds rear car driver to process.
Consult Fig. 2, for single unit vehicle, native system does not work, and it is mainly used in two car couplings and only uses.Adopt the aforesaid control method of synchronous control loop based on car networking, comprise the steps: that B driver that (A) is identical with A car drive route moves and follow after A car; (B) B car and the successful matching of A car, B car enters follows automatic Pilot state; (C) signal gathering unit 11 of A car gather A car vehicle location, turn to, throttle, brake information export processing unit 13 to; (D) information collected is exported to the processing unit 13 of B car by the processing unit 13 of A car by communication unit 14; (E) performance element 12 that the processing unit 13 of B car outputs signal to B car performs car brakeing, acceleration, steering operation; (F) A, B two car remove pairing, B car recover manual drive.In order to increase applicability, when the many car couplings of needs, also have C car after such as B car, now C car mates with A car or B car, and when mating with A car, C car is the same with B car, belongs to subordinate vehicle, follows A car and carries out automatic Pilot; When mating with B car, the processing unit 13 of B car not only outputs signal to performance element 12, also outputs signal to the processing unit 13 of C car.In like manner, more vehicle is followed, can one follow one, but now at a high speed on car speed disunity, many vehicles are followed exists certain risk, it is still further preferred that bicycle is followed.
Preferably, described steps A comprises the steps: that vehicle position information, routing information, pairing request are uploaded to server end 20 by (a) vehicle-mounted end 10; B another vehicle-mounted end 10 that the routing information uploaded according to B car of () server end 20 is identical with B bus or train route footpath with pairing request search; C () server end 20 sends the A truck position information searched to B car; D () B car is manually followed after A car according to A truck position information.For strange vehicle, need the path judging two cars whether identical before matching, only have and just carry out under identical circumstances matching and following.Carried out the coupling of routing information by server end 20, make native system better perfect.
Preferably, in described step a, the information that vehicle-mounted end 10 is uploaded to server end 20 comprises starting point and the endpoint information of vehicle, the starting point that server end 20 is uploaded according to vehicle-mounted end 10 and endpoint information are selected optimum driving path and export to vehicle-mounted end 10, and vehicle-mounted end 10 exports the driving path information after confirming or the driving path information after adjustment to server end 20.The starting point that server end 20 can also be uploaded according to vehicle-mounted end 10 and endpoint information, select optimum path, Integrated navigation system, provides convenient for driving.
