As shown in Figure 2, the control device of above-mentioned automotive back door further comprises: the memory 40 being connected with control device 30.

Particularly, in memory 40, store multiple predeterminable ranges and preset angles.Wherein, when predeterminable range and preset angles are pre-stored back door safe opening automobile rear object in each preset angles the minimum relative distance apart from back door.More specifically, can according to back door from closed condition to be opened into the process of maximum angle the space tracking of process determine the track of main point (as back door outside plate both sides end points and the outside plate mid point) process of back door, and as required according to multiple points on certain density calibration track, a preset angles and a corresponding predeterminable range can be determined in the position of each point.

Fig. 3 is according to the structured flowchart of the operating principle of the control device of the automotive back door of a specific embodiment of the utility model.

In a specific embodiment of the present utility model, as shown in Figure 3, control device 30 is also for before opening request signal control gating device 20 opening automobile back doors according to back door, whether the object that judges automobile rear according to the relative position of the object at automobile rear and automotive back door is within the scope of predeterminated position, and in the time that the object that judges automobile rear is not within the scope of predeterminated position, open request signal opening automobile back door according to back door.Further, control device 30 can be inquired about the preset angles consistent with relative angle in memory 40, and obtains the predeterminable range corresponding with preset angles, and in the time that predeterminable range is not more than relative distance, judges that relative position is within the scope of predeterminated position.

Particularly, control device 30 data that 10 transmission come according to sniffer calculate relative distance and the relative angle of obstruction and back door, mate with the preset angles in memory 40 according to relative angle, and obtain corresponding predeterminable range, then the relative distance calculating is compared with corresponding predeterminable range, if relative distance is greater than predeterminable range, judge that the object at automobile rear is not within the scope of predeterminated position, control device 30 does not send any instruction, and back door is normally opened; If relative distance is less than or equal to predeterminable range, judge that relative position is within the scope of predeterminated position, control device 30 sends halt instruction, controls gating device 20 and stops opening back door, and back door is rested on to current location, to avoid scratching to arrive the object at automobile rear.

In a specific embodiment of the present utility model, control device 30 is also for after control automotive back door stops opening, receive the length of back door switch is pressed to operation, and control gating device 20 closing automobile back doors, and control position sniffer 10 cuts out.More specifically, in the time that the object at automobile rear is within the scope of predeterminated position, back door stops opening, rest on current location, if now back door switch is again pressed and is sent back door and opened request signal, control device 30 no longer sends any instruction, back door attonity, reach Preset Time (for example, more than 5S) if long by back door switch, control device 30 is controlled gating device 20 closing automobile back doors, until after having closed, control position sniffer 10 cuts out, the control system of back door is got back to init state, wait for and receive next back door control instruction.

It will be appreciated that, in the process of gating device 20 closing automobile back doors, control device 30 can judge whether to exist object again within the scope of predeterminated position, to prevent from clipping to the object between back door and door pillar.

In a specific embodiment of the present utility model, positional detecting device 10 can be the one in camera, radar site sniffer, ultrasonic wave positional detecting device and infrared positional detecting device.More specifically, in the time that positional detecting device 10 is camera, camera can obtain the scene image at automobile rear, and control device 30 can carry out image recognition to obtain the object at the automobile rear in scene image to scene image, and obtains the object at automobile rear and the relative position of automotive back door.In addition, in the time that positional detecting device 10 is radar site sniffer, ultrasonic wave positional detecting device or infrared positional detecting device, control device 30 can be realized the detection to automobile rear object position by different recognition functions.

In another specific embodiment of the present utility model, positional detecting device 10 can be positioned on the outside plate of automotive back door, so that detect the position of the object at automobile rear.

The control device of the automotive back door proposing according to the utility model embodiment, by the object at automobile rear detecting and the relative position of back door and pre-stored preset angles and predeterminable range are made comparisons, judge within the scope of the safe opening of back door and whether have obstruction, in the time obstruction being detected, stop opening back door, and stop receiving back door start signal, the unnecessary loss of having avoided maloperation to bring, in the time growing by back door switch, close back door, operate easier, more intelligent, meet user's actual demand, promote user's experience.

In order to realize above-described embodiment, the utility model also proposes a kind of automobile of control device of the automotive back door with above-mentioned arbitrary embodiment.

In the description of this manual, the description of reference term " embodiment ", " some embodiment ", " example ", " concrete example " or " some examples " etc. means to be contained at least one embodiment of the present utility model or example in conjunction with specific features, structure, material or the feature of this embodiment or example description.In this manual, the schematic statement of above-mentioned term is not necessarily referred to identical embodiment or example.And specific features, structure, material or the feature of description can be with suitable mode combination in any one or more embodiment or example.

Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: in the situation that not departing from principle of the present utility model and aim, can carry out multiple variation, amendment, replacement and modification to these embodiment, scope of the present utility model is by claim and be equal to and limit.
