The embodiment of the present invention provides another kind of reversing control method, and for reversing control system as shown in Figure 2 or Figure 3, as shown in Figure 6, the method comprises:
The environmental information at step 601, vehicle mounted imaging apparatus collection vehicle rear.
Vehicle mounted imaging apparatus by being arranged on rear vehicle end in driving environment carries out real-time photography to the environment of rear view of vehicle, gathers the environmental information of rear view of vehicle when moveing backward.Example, this vehicle mounted imaging apparatus can be camera, camera can environmental information within the scope of Real-time Obtaining rear view of vehicle 300 meters to ensure that chaufeur makes accurate judgment to reversing environment.
The environmental information of the rear view of vehicle collected is sent to image receiving unit by step 602, vehicle mounted imaging apparatus.
Step 603, image receiving unit obtain the environmental information of rear view of vehicle.
Image receiving unit receives the environmental information of the rear view of vehicle that vehicle mounted imaging apparatus sends, the environmental information of rear view of vehicle is sent to graphics processing unit.
The environmental information of rear view of vehicle is sent to graphics processing unit by step 604, image receiving unit.
When running into the weather such as rainy day or greasy weather, can there is interfere information in the environmental information of the rear view of vehicle that image receiving unit gets, the image fault that this interfere information causes for weather conditions, and image fault can affect the accuracy that chaufeur judges reversing environment.Example, weather conditions can be rainy day or greasy weather.Image receiving unit needs the environmental information of rear view of vehicle to be sent to graphics processing unit, so that the environmental information of rear view of vehicle is further processed.
Step 605, graphics processing unit filter the interfere information in the environmental information of rear view of vehicle and obtain the environmental information after processing.
Interfere information in the environmental information of rear view of vehicle, by image processing algorithm, filters out by graphics processing unit, thus restores true image clearly, makes correct judgement to enable chaufeur to reversing environment.Example, the Mean Filtering Algorithm in image procossing can be adopted to filter interfere information, mean filter is a kind of linear filtering algorithm, refer on image to object pixel template, this template includes the adjacent pixels around it, replace original pixel value by the aviation value of the entire pixels in template, the environmental information after process can be obtained.
Environmental information after process is sent to image-display units by step 606, graphics processing unit.
The environmental information of true rear view of vehicle is clearly sent to image-display units by graphics processing unit.
Environmental information after step 607, image-display units Graphics Processing.
Image-display units receives the environmental information after the process of graphics processing unit transmission, and the environmental information after process is showed chaufeur.
Concrete, image-display units comprises: image projection unit and reflectance coating, and step 607 can comprise: the environmental information after process is projected to the reflectance coating be arranged on the Windshield of vehicle by image projection unit.
Reflectance coating can increase the reflectivity of optical surface, is projected on reflectance coating, the environmental information after process can be made to present very clearly by the environmental information after process, ensures that chaufeur makes correct judgement to reversing environment.
It should be noted that, this reflectance coating can be pasted onto on the Windshield of chaufeur right opposite in advance, therefore, the reversing control method that the embodiment of the present invention provides is compared to the method for existing visual surround information on the screen of navigating instrument, chaufeur, without the need to diverting sb.'s attention, only need see that the environmental information of rear view of vehicle easily can be observed in dead ahead, obtains reversing environment, understand traffic information, avoid chaufeur and sight line is departed from road surface and causes Peril Incident.Meanwhile, the size of reflectance coating can be greater than the screen size of existing navigating instrument, and the image that chaufeur is observed is more clear.
Step 608, the brake controller be connected with drive button receive the manipulation order of chaufeur to drive button.
Drive button controls button when brake controller realizes vehicle backing, and when needing reversing, chaufeur reversion drive button, makes brake controller receive the manipulation order of chaufeur to drive button.
Step 609, brake controller switch the state of vehicle.
The state of vehicle is forward travel state or fallback state.Brake controller receive chaufeur to the manipulation order of drive button after, the state of vehicle can be switched, vehicle is made to be fallback state from advance state-transition, example, after reversion drive button, the D gear switch of original instruction forward travel state can be the R gear of instruction fallback state by brake controller.
It should be noted that, in reversing process, chaufeur is according to the environmental information of the rear view of vehicle that reflectance coating shows, brake controller can be controlled according to normal working direction to control vehicle, the observation that can realize not turning one's head is driven, now, vehicle is at backward, when but the environmental information of the rear view of vehicle shown on the reflecting film travels as normal advance from the traffic information in the front that Windshield is seen, chaufeur is felt, and vehicle travels in advance, further increases the safety of reversing.After treating that car backing operation terminates, reverse drive button again, makes brake controller change forward travel state into from fallback state.
It should be noted that; the sequencing of the reversing control method step that the embodiment of the present invention provides can suitably adjust; step also according to circumstances can carry out corresponding increase and decrease; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; the method changed can be expected easily; all should be encompassed within protection scope of the present invention, therefore repeat no more.
In sum, the reversing control method that the embodiment of the present invention provides, image receiving unit can obtain the environmental information of rear view of vehicle, then graphics processing unit can filter the interfere information in the environmental information of rear view of vehicle and obtain the environmental information after processing, environmental information after last image-display units Graphics Processing, the interfere information of the image fault that weather conditions cause is there is not in the environmental information of the rear view of vehicle that chaufeur is observed, thus effectively can control vehicle, this improves the safety of reversing.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
