Embodiment
Describe according to the raising Long-distance Control vehicle safety method of the embodiment of the present invention below with reference to Figure of description.
As shown in Figure 1, it is the system architecture that realizes the present invention and improve Long-distance Control vehicle safety method, and this system comprises and comprises client, pretreatment unit, performance element.Client is remote control terminal, sends Long-distance Control request (being called for short the request of control), can be the Wireless Telecom Equipment such as mobile phone, PDA; Pretreatment unit and performance element are car-mounted device, between Unit two, are connected by CAN bus, the collaborative Long-distance Control request of carrying out client transmission.Client and pretreatment unit are realized the mutual of information by wireless networks such as 3G.
As shown in Figure 2, the present invention improves Long-distance Control vehicle safety method and comprises the following steps:
Step 1, client and pretreatment unit carry out authentication, and after authentication success, client sends to pretreatment unit the request of control.
Client and pretreatment unit (are initiated before Long-distance Control request, before step 1) binding in advance, and in the time entering Long-distance Control, client and pretreatment unit need to carry out authentication.First initiate authentication request by client; Pretreatment unit receives after authentication request, sends random number to client; The number that client produces while binding in advance according to random number and coupling fixed number T1(client and pretreatment unit is recorded by client and pretreatment unit simultaneously) by cryptographic algorithm, calculate the result, and send the result to pretreatment unit; Whether the result that pretreatment unit verification client sends is correct, and result is correctly proved to be successful, and is proved to be successful to client feedback, and client sends the request of control to pretreatment unit by 3G network; Authentication failed, to client feedback failure cause, i.e. authentication failed.In order to guarantee the security of system, described control request can be the encryption control request after encrypting.
Step 2, pretreatment unit judge that whether this control request is legal, and parse control command.
Pretreatment unit receives and resolves client control request, obtains corresponding control command, and judges whether the request of control is legal, whether be effective control request of agreement agreement, if it is legal to control request, continue to carry out, otherwise feedback client control request is invalid.For example: remote control command that system protocol can be realized for client in advance (as unblank, engine start, power on etc.) is set different indications, in the time that the indications of the expression remote control command of carrying in control request does not meet predetermined indications, think that this control request is illegal, simultaneously invalid to client feedback control request, carry out subsequent step if meet.If the client control request receiving is for encrypting the request of control, pretreatment unit is receiving after this encryption control request, also needs to be decrypted encrypting the request of control.
Step 3, when legal, pretreatment unit judges whether each Vehicular status signal meets the Long-distance Control requirement of this control command.
When pretreatment unit receive be legal control request time, receive the Vehicular status signal that each controller of vehicle or signal picker gather, according to judging corresponding to the predetermined condition of control command whether each Vehicular status signal meets the Long-distance Control requirement of this control command, described Vehicular status signal comprises vehicle power supply status signal, door lock state signal, whether gear signal etc. meets Long-distance Control requirement, if meet Long-distance Control requirement, pretreatment unit is initiated authentication request to performance element, do not meet and feed back client control failure cause, for example certain Vehicular status signal does not meet the Long-distance Control requirement of this control command.Take control command for powering on as example, if it is that vehicle power supply status signal is that OFF, door lock state signal are for closure, gear signal must be at P shelves or N shelves that the Long-distance Control of the predetermined satisfied control command powering on requires, in the time meeting above-mentioned condition, carry out again the authentication between pretreatment unit and performance element simultaneously, otherwise do not carry out follow-up authentication, and to client feedback control failure cause (if because door lock state signal is to open not meet the Long-distance Control requirement powering on, feedback door lock status signal does not meet Long-distance Control requirement).
The Vehicular status signal that determining whether in the present invention meets Long-distance Control requirement is not limited only to foregoing, also comprises vehicle body anti-theft state signal, speed of a motor vehicle status signal, on-position signal etc., can arrange flexibly according to actual conditions in actual applications.
Step 4, when meet this control command Long-distance Control require time, pretreatment unit and performance element carry out authentication, after authentication success, performance element is proved to be successful timing, whether finish to judge that according to being proved to be successful timing whether authentication result effective, and by authentication result whether effectively Real-time Feedback to pretreatment unit.
The authentication of carrying out between pretreatment unit and performance element is similar to the authentication mode between pretreatment unit to client in step 1: pretreatment unit is initiated authentication request to performance element, performance element receives after checking request, send random number to pretreatment unit, pretreatment unit (is initiated before Long-distance Control request when binding performance element in advance according to random number and its, before being step 1) the coupling fixed number T2 that generates passes through cryptographic algorithm, calculate the result, send the result to performance element, whether the result that performance element verification pretreatment unit calculates is correct, correctly authentication success, feedback authentication successful information is to pretreatment unit, if checking is not passed through to pretreatment unit feeding back unsuccessful reason, it is authentication failed.Certainly in being verified, performance element starts to be proved to be successful timing simultaneously, judge that according to being proved to be successful timing whether authentication result is effective, and by authentication result whether effectively Real-time Feedback to pretreatment unit: timing finishes front identity the result for effectively, performance element by effective authentication result verification Real-time Feedback to pretreatment unit, if now pretreatment unit receives the new control request that client sends, can omit the authentication step of step 4; After being proved to be successful timing and finishing, performance element is removed authentication result, authentication result is invalid, and by invalid authentication result verification Real-time Feedback to pretreatment unit, if now pretreatment unit receives the new control request that client sends, need to re-execute the authentication of step 4.
Can avoid carrying out in the short time by being proved to be successful timing the authentication that multiple continuous remote control commands need repeated execution of steps four, that reduces communication link blocks up, reduces system-computed amount, improves system execution efficiency; Prevent from verifying the illegal Long-distance Control of rear other staff to vehicle simultaneously.
Step 5, when receiving after the effective feedback message of authentication result of performance element, pretreatment unit sends control command to performance element.
Pretreatment unit is receiving the authentication success message of performance element feedback, and after the effective information of authentication result, sends control command to performance element.
Step 6, performance element determine that whether the authentication result between pretreatment unit and performance element is effective, and whether each Vehicular status signal meets the Long-distance Control requirement of this control command, if the result is effective and meet Long-distance Control requirement, carry out remote control command.
Owing to being proved to be successful after being proved to be successful in the time period of timing, between pretreatment unit and performance element, authentication result is remained valid always, performance element receives after the control command of pretreatment unit, again judge whether effectively (being proved to be successful timing not yet finishes) of authentication result between pretreatment unit and performance element, preventing the erroneous judgement of pretreatment unit to authentication result, is not successfully effectively in situation, to carry out control command in authentication; Performance element receives the Vehicular status signal of each controller of vehicle or signal picker collection simultaneously, again judge whether each Vehicular status signal meets Long-distance Control requirement, this determination methods is identical with step 3: according to judging corresponding to the predetermined condition of control command whether each Vehicular status signal meets the Long-distance Control requirement of this control command, for example, judge whether vehicle power supply state, door lock state, gear etc. meet Long-distance Control requirement.
If authentication result is effective, Vehicular status signal meets Long-distance Control requirement simultaneously, carry out remote control command, performance element starts Long-distance Control timing simultaneously, thereby do not meet Long-distance Control condition if Long-distance Control timing finishes or Vehicular status signal changes, exit Long-distance Control, whole vehicle state returns to the front state of Long-distance Control.
If authentication result is invalid, or Vehicular status signal do not meet Long-distance Control requirement, and FEEDBACK CONTROL failure cause is to pretreatment unit, pretreatment unit feedback client operation failure cause.
Although illustrated and described embodiments of the invention, for the ordinary skill in the art, be appreciated that without departing from the principles and spirit of the present invention and can carry out multiple variation, modification, replacement and modification to these embodiment, scope of the present invention is by claims and be equal to and limit.
