On-board device for assisting the driving and speed limit compliance with proof of speed limit in relation to location

The present invention relates to a device to help driving with recording speed of road vehicles on their route, involving a type imaging slideshow or video; the This invention extends its capabilities in the field of speed control.

The device according to the invention is intended primarily to prove by the driver when the speed of his vehicle its displacement and therefore more particularly to a forming location the subject of dispute. The device, bringing the images of journeys made with dates and times, is the most applications variety.

The invention relates to the field of transport and security. It is intended for road professionals and individuals, Light Vehicles and Trucks, new drivers and more experienced wishing to travel with confidence. The device is to be produced industrially to equip vehicles rises of origin, or additional equipment.

There are devices, including trucks, recording the instantaneous speed, and you can hardly find there the number and duration of stops and maximum speed; it does not offer no information in relation to road profile and its location; the vehicle traveling at 80 km / h it was highway, road or agglomeration?

The device according to the invention will allow to memorize for viewing on demand, the distances covered with information speed with respect to its position. The location is by imaging; the device control overlay on the image before facing the road, the following essential information: date, hour-minute-second, trip and time, current speed, direction sounds ie if speed is increasing or decreasing, and the threshold-level crossing.

The landing threshold: Although digital storekeepers can record a non-stop route from week with a capacity of 120 gigabytes, or about ten thousand kilometers away, for reasons of cost embodiment it is better to save memory capacity for video, and can satisfy image-established thresholds at different levels programmable; these are initially the number of sixteen, and positioned at the following speeds in km / h: 0, 30, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, x ..

The user is informed by the operating parameters selected, furtively or permanently, firstly by visually a head-up projection of the instantaneous speed, the last threshold crossed and sense the other by auditory beeps programmable in frequency and volume as bearings; the characteristics threshold crossing warning is a new driving assistance for engaging in manually or automatically the existing cruise control of the vehicle or automatically if there is associated with the device. For explain two examples: in decreasing speed crossing the threshold 50 km / h command control at that speed, regulation immediately inhibited by an action on the brake, accelerator or manual removal of the device; Another example: the vehicle up the speed and threshold of 130 km / h, the device indicates the driver as described above, and it would command the control except Excessive pressure on the accelerator or another parameter inhibitor. The device is equipped with a control keyboard which allows User prohibit temporarily and instantly, automaticity programmed to a threshold; example: vehicle speeds 130 and found a limited area to 90, pressing the button 90, allows regulation to 90 km / h as soon as this speed is reached.

User can apply the device at any time by forcing the control of image capture, single or burst mode, Image capture can also be controlled by any accessory Embedded air bag system, attitude change detector, alarm volumetric or stress when a multimedia Embedded.

Architecture and detailed operation of the device in the basic version:<ul><li>Contact Food: contact or switching on the motor, device is turned on and activates its peripherals.</li><li>speed information in the absence of authorization for radio and speedometer also for reasons of cost, the device receives the speed information by a sensor placed on the vehicle to be created or existing mechanical, Electric or from an ABS or board computer calculator; the Information speed quantification requires the utmost precision, to an accuracy less than 1%; the device will allow an adjustment not global, but in a manner in steps to overcome any drift; Calibration then the filling, will be possible only by a certified organization. Verification by the user at constant speed remaining always possible. </li><li>quantification Floor: after adjustment of the frequency signal to the device, the integrated computer determines the instantaneous speed, its direction, if increases or decreases, and increments a trip meter and totalizer without reset. These items are scanned and formatted for subsequent stages.</li><li>Floor comparison: the speed information having been quantified, it is transmitted to this floor be compared to sixteen bearings-thresholds; the crossing of a threshold involves activation of assistive devices to conduct and requests the video store command. The comparator is so constituted that any transitional and all are bagotement excluded in case of constant speed around a threshold;</li><li>The driving assistance devices are integrated into the housing of the device</li></ul>or deported. They are all customizable from the floor .In quantization, information instantaneous speed and direction, and from the comparator stage last crossed the threshold are displayed on the device and / or head-high projection. The crossing of a threshold it there is an audible beep and activating an output for control external speed controller.<ul><li>video storage Upstairs: the crossing of a threshold, upstairs Compare sends a command to the video storage stage which triggers the immediate seizure of an image with the camera facing the road, image on which are embedded the following information available: the current speed, the direction, the threshold in clear, mileage, and which are added the date and hour minute second. The control of this stage may be sought in various uses: a remote button allows the user to enter an image at any time to spend in burst mode if the button is held; it is also an access to the media or external control.</li><li>The data storage floor: acquisition and storage of information presented in the video room controls through permits software to provide diagrams thresholds crossed at speed ordinates, and time on the abscissa; this information useful supplement imaging and will facilitate research. These records are independent the state of operation of the video storer.</li><li>The various floors are under control of an evaluation stage which allows a the user through a drop-down menu to adjust all features.</li></ul>

According to particular embodiments:

If memory is sufficient for permanent video option, the device continuously integrates its information.

The positioning of the cameras on the vehicle and their number are independent of the actual device.

The device can use multiple cameras or infrared type no..

The device may be integrated partially or fully board computer or any of its peripherals.

The number of configurable levels can evolve as needed to down for more autonomy with the same storage capacity, or upward for better accuracy. The device in a given version can that analyzing a number of bearings.

The video storage stage is external to the device and / or it is equipped multiple cameras. Storing the imaging is done according to the best suited economically and media available on the market: mass memory, DVDRW .....

The keyboard thresholds displays the speed at which directly the user wants to roll, then the regulator to achieve and maintain that speed.

Depending on the environment selected new features are possible:

Quality-picture imaging is directly and easily adjustable by the user can thus pass the standard quality fixed in the power tension, to photo quality.

The device is connected to car multimedia. The device makes its available information and triggers the order.

a video surveillance function is obtained and the location of vehicle. Images are sent automatically by the embedded or remote polling mode devices. In this video surveillance capability, capturing images can then be entrusted asymmetrical alternating with a second cockpit camera and images made every second example (facing the road - cabin) sent via a mobile telephone network conference to ensure backup on a server and have them live on a selected terminal and adapted. We can follow the route taken with a stolen vehicle without share at the time of the flight, simply query the device to see the chosen route. remote actions can be sent (stopping the vehicle for example). The device is adaptable in the maritime and aviation domains.
