Useful technique effect of the present invention is:
(1) the present invention is by gathering the collision alarm of safety air sac controller, as the foundation of release, makes the system can be at car collision moment automatic unlocking, and child lock can't release under powering-off state after having avoided accident to occur, and the occupant can't save oneself.
(2) the on off state information that the present invention feeds back child lock by the status request signal that receives the ECU transmission to ECU, make the user can get at any time the state of child lock; Whether be pulled to the on off state information of ECU feedback child lock by induction automobile Internal handle simultaneously, locked when child lock, can point out relevant information by ECU to the user immediately.
(3) the present invention, by carrying out IMAQ in car, carries out face characteristic identification to image, and obtains engine rotational speed signal, and then judgement output locks on signal controlling child lock automatic locking, makes the more intelligent hommization of control, and convenient and reliable.
The accompanying drawing explanation
The structural representation that Fig. 1 is control system of the present invention.
The control flow schematic diagram that Fig. 2 is child lock controller of the present invention.
The specific embodiment
In order more specifically to describe the present invention, below in conjunction with the drawings and the specific embodiments, technical scheme of the present invention and control procedure thereof are elaborated.
As shown in Figure 1, a kind of control system of child lock for automobile comprises: the child lock controller;
Lock-switch, it is to child lock controller transmit button signal;
Video camera, it gathers image in car, and image in car is sent to the child lock controller;
Three Internal handle sensors, it is connected with the Internal handle on three non-main driving car doors of automobile respectively, and when Internal handle is pulled, the Internal handle sensor can be responded to the generation unlocking signal, and unlocking signal is sent to the child lock controller.
The child lock controller comprises: communication module, picture recognition module and MCU.
Communication module communicates by CAN bus and safety air sac controller, engine controller and ECU, and obtains the collision alarm of safety air sac controller, the engine rotational speed signal of engine controller and the status request signal that ECU sends; Wherein collision alarm, engine rotational speed signal and status request signal are differential signal, and communication module offers MCU after these signals can being converted to data signal.
Picture recognition module is connected with video camera, and image in the car of camera acquisition is carried out to face characteristic identification, has children within recognition result shows car, and lock signal is closed in its output; Wherein in the car of camera acquisition, image is a series of data signals, picture recognition module is first carried out feature extraction to this series digit signal, then by respective algorithms, the characteristic information and the reference information in internal database that extract are carried out to the matching degree computational analysis, and then judgement identification.
MCU is connected with child lock, communication module, picture recognition module, lock-switch and Internal handle sensor, and, according to the switching signal of lock-switch, the pass lock signal that picture recognition module produces, collision alarm and the engine rotational speed signal that communication module transmits, in output, lock signal or unlocking signal are to control child lock;
Work as MCU simultaneously and receive the unlocking signal of Internal handle sensor generation or the status request signal that communication module transmits, MCU sends the on off state information of child lock to ECU by communication module.Wherein switching signal and unlocking signal are the level signal of switching value, before its input MCU, all need to carry out the coherent signal conversion, are about to level signal and are converted to data signal; The on off state information that MCU transmits to communication module simultaneously is data signal, and communication module can be converted to differential signal by this signal and send to ECU.
When switching signal, for closing signal (digital quantity is 1) or closing lock signal and rotating speed corresponding to engine rotational speed signal is greater than 500 rev/mins when MCU receives, MCU output is locked on signal controlling child lock automatic locking.
When switching signal receives collision alarm for opening signal (digital quantity is 0) or working as MCU, MCU output unlocking signal is controlled child lock and is automatically untied.
Wherein go up lock signal and unlocking signal is level signal, before offering child lock, need carry out the coherent signal conversion to these level signals, convert the high voltage signal of 12V to drive the child lock action.
As shown in Figure 2, controller is Real-time Collection CAN bus signals (comprising collision alarm, engine rotational speed signal, status request signal) at first for the control flow of the child lock controller of present embodiment; Then, in the CAN bus signals that the controller judgement collects, whether comprise collision alarm and status request signal: if comprise the status request signal, controller is the on off state information about child lock to the ECU feedback; If comprise collision alarm, controller drives child lock automatically to untie, if do not comprise collision alarm, controller judges whether the rotating speed that the engine rotational speed signal of engine controller is corresponding is greater than 500 rev/mins, if, controller carries out face characteristic identification to image in the car of camera acquisition simultaneously, has children within recognition result shows car, and controller drives on the child lock automatic locking; If not, controller drives child lock to untie or lock (if lock-switch is off status, on the pass signal driver child lock automatic locking that controller provides according to it according to the switching signal of lock-switch; If lock-switch is for opening state, the signal driver child lock of opening that controller provides according to it is untied automatically).
In control procedure, the controller unlocking signal that also Real-time Collection Internal handle sensor provides is (when Internal handle is pulled, the Internal handle sensor can be responded to the generation unlocking signal), if controller receives unlocking signal, it can feed back the on off state information about child lock to ECU; Especially when child lock is locked, the passenger pulls Internal handle to attempt to open car door, and ECU can show the on off state information about child lock, and locked with prompting driver child lock, the driver judges whether release according to actual conditions.
