Method and device for sampling and processing data of vehicle driving lesson

0001The present invention relates to a method for acquiring and learning data processing driving a vehicle. She also concerns a device implementing this method.

0002The invention will find its particular application in the field of learning motor vehicle of driving school types in addition driving lessons with an instructor.

0003Known from WO-A-9734277 a support device learning to control a plane including means video and audio data recording for further processing. In Particularly, it is possible to mark events on the record to located and replay the passage appears.

0004This type of device has various disadvantages and in particular use of high capacity storage means. It must indeed store all the audio and video recording data. Considering the magnitude of the stored data, the return time on a portion of marked data is relatively long.

0005This device is in its complex and not very adaptable to all technical fields such as that of self -école requiring structure lighter and cheaper.

0006The present invention overcomes all or part of these disadvantages and present it to a new process and a new data acquisition and processing device for learning driving a vehicle.

0007The invention has the advantage of not requiring a final repository that only certain portions of the audio data and captured video. We can and select the data to permanently store which limits required storage capacity and simplifies subsequent processing. It is thus design a lightweight and inexpensive device structure.

0008The process proposed here allows the student to become aware concretely the mistakes he made and visually see afterwards.

0009The invention serve in particular to develop and enhance the profession driving school in modernizing and creating jobs.

0010Other objects and advantages will appear during the description follows of a preferred embodiment of the invention which is not limiting.

0011The present invention relates to a method for acquiring and processing training data driving a vehicle comprising:<ul><li>a step of learning data acquisition comprising audio and video data</li><li>a step of storing the training data</li></ul>

0012The step of storing the training data comprises:<ul><li>a first storage continuously acquired data in a first storage unit</li><li>a selection of a part of the acquired and stored data;</li><li>a second storage of the selected portion of data in a second storage unit.</li></ul>

0013This method is such that: <ul><li>Selecting a part of the acquired data contains the steps of:<ul><li>inputting a control signal by the user,</li><li>extracting from the first storage unit the data acquired during a predetermined time period before the signal input of order</li><li>store the extracted data in the second storage unit.</li></ul></li><li>Also extracted from the first storage unit the data acquired during a predetermined period of time after the input of the control signal,</li><li>Using a second storage unit in the form of a removable memory,</li><li>It retrieves data stored on the second unit storage on a personal computer, for further processing.</li></ul>

0014The invention also relates to a device for acquiring and processing training data driving a vehicle comprising:<ul><li>means for acquiring learning data including means of audio and video acquisition</li><li>means for storing the acquired data, The storage means comprises:</li></ul><ul><li>a first storage unit continuously acquired data,</li><li>a second storage unit of a selected portion of the acquired and stored data in the first unit storage,</li></ul>   and in that it comprises means for selecting a portion of data acquired and stored in the first storage unit.

0015Advantageously, the device is such that:<ul><li>The selection means comprise a control member for inputting a control signal and means for processing configured to extract from the first unit storing the data acquired during a period of time predetermined before the input of the control signal, </li><li>The processing means are configured to extract also of the first storage unit the data acquired during a predetermined time after the input of the signal command,</li><li>The second storage unit is a removable memory,</li><li>It includes a personal computer for retrieving data stored in the second storing unit for further processing.</li></ul>

0016The attached drawings are given as examples and are not limiting the invention. They represent only one embodiment of and the invention will be easily understood.

0017Figure 1 shows an embodiment of a device of the invention on board a motor vehicle.

00182 schematically shows the components of the device the invention in the embodiment of Figure 1.

0019Referring to Figure 1, the device proposed here may be picked in any type of vehicle and for example a motor vehicle used as part of a driving school business.

0020This device comprises data acquisition means learning and in particular to video and audio data. these means acquisition are marked (7, 8) in Figure 1 and 2. One may use a camera or a Web camera equipped with a wide angle lens placed inside the vehicle to constitute the video acquisition means (7). The camera can be positioned on the front right windshield behind the rearview mirror inside, or even on the dashboard to allow a vision of hood of the automobile (or other vehicle) and the hundred meters ahead of the vehicle. Note that you can also install the device on a motorcycle by placing the camera on the handlebar or on the headlights. The audio acquisition means (8) can be constituted by a micro atmosphere routine design, the remainder of the device may be implanted in a following vehicle connected by link means to HF radio located on the motorcycle.

0021In other cases, these acquisition means (7, 8) are connected to all common means and in particular by a wire connection to a central unit (1) feasible as a personal computer of the notebook type comprising preferably a ROM capacity of about 20 gigabytes.

0022The central unit (1) also includes other peripherals form of a control member (6) adapted to be actuated, in particular by manual pressure by the user. For example, the control member (6) a pear is connected by a cord to the computer. The controller (6) allows the input of an event at the central unit in order to trigger an action of selecting audio and video data as will be described more in detail below.

0023The central unit (1) is also connected to a display (5) for viewing video data and the graphical interface for the management of device.

0024As shown in Figure 2, the device further comprises a unit storage (4) preferably removable and may be compliant PCMCIA although this solution is not limiting.

0025Is described below more exactly the course of setting practice of the invention.

0026In a driving situation, the video capture means (7) Audio (8) are activated so as to store the corresponding data in the resident storage unit (3) of the central unit (1).

0027During this operation, the monitor responsible for learning conduct monitors the actions of his pupil. If it detects a situation of pipe on which he wants to specifically attract student attention (Especially in case of driver error), the monitor generates a signal control through the control member (6). This signal triggers a selection of a part of the data acquired and stored for one storing this selected portion in the second storage unit, the unit removable storage (4).

0028In a preferred embodiment, the control signal generated by the monitor triggers storing in the removable storage unit (4) Data acquired ten seconds before the control signal, and ten seconds after said control signal.

0029Thus ultimately keeps memory in the unit (4), the selected data on which students will increase its work. By against, the remaining data stored in the storage unit (3) can be erased at the end of the driving lesson or continuously by Refreshments.

0030In a particular embodiment, the data stored in the storage unit (4) are recovered at a personal computer, eg driving instructor's office, to perform processing ulterior. In particular, it is possible to write data back into a easily readable by the student as a CD ROM or other media audio-visual. We can also make arrangements including data recovered when driving and other corresponding data eg in typical situations.

0031Of course, the embodiment thus presented is not limiting the invention. In particular, the components of the device may use means of transmission of different types including wireless transmissions.
