Step 3: key self-information, after receiving low frequency signal, is carried out encoding and fed back away by high-frequency signal by key 11.
Whether correct key 11, when receiving low frequency signal, first judge to wake frame up, if mistake just directly abandons, if correctly then first decode; Then judge that whether CRC check position is correct, if mistake, illustrating that data are wrong, without the need to processing again, directly abandoning, then continue to judge that whether the vehicle body ID in Frame is correct if correct; If mistake, illustrating that this wakes up is not the request that vehicle corresponding to key proposes, may be other with money vehicle, without the need to processing again, directly abandon; If correct, illustrate that request found by the current key really sent for corresponding vehicle.Now, key 11 can obtain function solicited message further from Frame, learn that current is that tail-gate antenna searches key, so key 11 will to itself information (i.e. key ID, dispatch from the factory password etc.) encode according to prescribed form as shown in Figure 5, then send high-frequency signal by high frequency (adopting 314MHz).
The frame format of high-frequency signal, as Fig. 5, comprises and wakes frame, CRC check position and Frame up, and wherein data frame packet is containing key self-information, and key self-information comprises key ID and the password that dispatches from the factory.
Step 4: Body control module 2 receives the high-frequency signal of key 11 transmission by high-frequency reception module 7, is confirmed whether as legal key, if non-rule does not respond, otherwise enters next step.
After high-frequency reception module 7 have received high-frequency information, whether correctly first judge to wake frame format up, if mistake just directly abandons, if correctly then first decode, then judge that whether CRC check position is correct; If mistake, illustrating that data are wrong, without the need to processing again, directly abandoning; If correct then by LIN, the key self-information in Frame is sent to Body control module 2; By the key self-information comprised in Frame, Body control module 2 judges that whether current key is correct; If correct, then think that key certification is passed through; Otherwise key authentication error, does not namely find legal key.
Step 5: Body control module 2 judges current tail-gate on off state, if be in opening, does not then respond, if the closed condition of being in, then sends by bus the request of enabling and asks to open tail-gate to tail-gate control module 3.
Whether Body control module 2 judges current tail-gate on off state, if the closed condition of being in, be in vehicle invasion anti-theft protection, if so, then remove invasion anti-thefting monitoring before also will judging.
Wherein, vehicle invasion anti-theft system is responsible for the on off state of monitoring all car doors, tail-gate (case cover) and bonnet (can not want) in real time after car load is locked, and open if find that there is an accident, then pipe loudspeaker immediately, and start two flashing light, to show warning.In the process that tail-gate is opened automatically, consider that the unlatching of tail-gate can cause the change of tail-gate switch (become by closedown and open), and be now very likely still in the monitor procedure of vehicle invasion anti-theft system, in order to prevent the false triggering of burglar alarm, need the invasion anti-theft system of first closing vehicle, and then start the function that tail-gate opens automatically.
Step 6: tail-gate control module 3 judges whether to meet the automatic unlocking condition of tail-gate after receiving the request of enabling again, if do not meet, does not respond, otherwise opens tail-gate.
Whether tail-gate control module 3 needs can open tail-gate comprehensively to judge, according to the present invention, the automatic unlocking condition of tail-gate comprises: the in the closed position or tail-gate of (1) tail-gate stops at the position of a certain non-closedown; (2) vehicle is in parking stall or the speed of a motor vehicle lower than 1 kilometer/hour (this value can be demarcated); (3) the electronic windscreen wiper of tail-gate and demist heating are in closed condition; (4) tail-gate place does not hang towing equipment; (5) self-inspection of tail-gate control module is passed through.
