- FIG. 33 [33][Fig 1] illustrates a system for homologating a motor vehicle according to certain embodiments of the invention
- FIG. 34 illustrates a marker of an accelerator pedal of a vehicle approval system according to certain embodiments of the invention
- FIG. 35 is a diagram illustrating a method of approval of a motor vehicle according to embodiments of the invention.
- FIG. 36 [36][Fig 4] illustrates the structure of a data processing device according to certain embodiments of the invention.
- Figure 1 presents an approval system for a motor vehicle 100 according to certain embodiments of the invention.
- the approval is based on at least one test situation which defines a target percentage, or a target fraction, of the maximum travel of an accelerator pedal, or an interval centered around such a percentage target or such a target fraction.
- the test situation may define a target percentage of maximum acceleration, or an interval around a target percentage of maximum acceleration.
- This target percentage of maximum acceleration corresponds bijectively to a target percentage of maximum travel of the accelerator pedal 101, although the function relating them is not linear.
- test situation can thus impose maintaining the accelerator pedal in a target position or in a range of positions around the position target, the path between the rest position and the target position corresponding to the target percentage of the maximum path.
- Each test situation can also define a given path of the vehicle on a test track, for example between a test start position and a test finish position.
- the accelerator pedal 101 can in fact vary between a rest position 201.1, when no pressure is applied to it by a driver, corresponding to zero acceleration, and a position of maximum acceleration 201.2, when the driver presses the pedal so that it pivots or translates to an extreme position beyond which the pedal can no longer go.
- a rest position 201.1 when no pressure is applied to it by a driver, corresponding to zero acceleration
- a position of maximum acceleration 201.2 when the driver presses the pedal so that it pivots or translates to an extreme position beyond which the pedal can no longer go.
- Such an extreme position may, on certain vehicles, correspond to a position just before a kickdown downshift.
- the approval system may comprise a marker 102 arranged on the accelerator pedal 101, preferably on a lateral surface, substantially vertical, so that the route in translation or rotation of the accelerator pedal can be determined by detection of the trajectory of the marker 102.
- the marker is preferably arranged on a surface according to a vertical plane normal to the Y axis, in particular on a lateral surface of the pedal, which is not covered by the driver's foot when pressing the accelerator pedal 101.
- the marker 102 may be a paper or plastic based sticker.
- the marker 102 is of a color making a significant contrast with the color of the accelerator pedal 101. If the accelerator pedal 101 is black, the marker 102 can advantageously be white.
- the marker 102 is an identifiable part of the accelerator pedal 101, already part of the accelerator pedal 101, and requiring no addition.
- the accelerator pedal 101 may include a mark or marking of a color different from the rest of the accelerator pedal and which can be identified.
- the system may further comprise an image acquisition device 103 such as a camera or preferably a camera.
- an image acquisition device 103 such as a camera or preferably a camera.
- the example of a camera 103 is used to simplify the description.
- the camera 103 is arranged inside the vehicle so as to acquire still images or preferably videos comprising the marker 102.
- the marker 102 is thus in the field of the camera 103 which is preferably positioned near the accelerator pedal 101, under the steering wheel near the floor of the vehicle 100 for example. No restriction is attached to the resolution of the camera 103, which must at least be capable of identifying the position of the marker 102.
- the approval system may further comprise a data processing device 104, such as a computer, a laptop, a touchscreen tablet, or more generally any device having a memory, a storage unit data processing and a human machine interface to interact with a user.
- a data processing device 104 such as a computer, a laptop, a touchscreen tablet, or more generally any device having a memory, a storage unit data processing and a human machine interface to interact with a user.
- the device 104 is a portable computer. It may for example be a laptop computer with an IntelTM i5 or i7 microprocessor, in which software capable of implementing certain of the steps of the method according to the invention, has been downloaded and installed, and which makes it possible to follow visually or by audio feedback, the path of the accelerator pedal 101, as will be better understood on reading the following.
- the computer 104 is thus able to communicate and exchange data with the camera 103, in particular via a communication interface 108, preferably wireless.
- the communication interface 108 can be integrated into the camera 103.
- the communication interface 108 can be of the Wifi or Bluetooth type for example.
- the computer 104 can, according to certain embodiments of the invention, display images or a video stream including a visual indicator identifying the position of the accelerator pedal 101, and identifying the target position or the target path . A technical team is thus enabled to visualize, for example in real time, the position of the accelerator pedal 101, which allows them to provide instructions to the driver.
- the data processing device 104 is installed directly in the vehicle 100 so that the driver can directly monitor in real time the position of the accelerator pedal 101, and in particular its deviation from the target position.
- the displayed image or video stream may also include information indicating whether or not the difference between the target position 201.3 and the position of the accelerator pedal 101 is less than a given threshold.
- Such information may correspond to a given color, in order to facilitate its understanding by the driver of the vehicle 100.
- Such information may be binary. For example, a green pictogram can be displayed when the deviation is less than the given threshold, and a red pictogram can be displayed when the deviation is greater than the given threshold.
- such information can take three values: a first value when the deviation is less than the given threshold, a second value when the deviation is greater than the given threshold and the position of the accelerator pedal 101 is closer from the rest position than the target position, and a third value when the difference is greater than the given threshold and the position of the accelerator pedal 101 is less close to the rest position than the target position.
- a dedicated color can correspond to each of these three values.
- the computer 104 can indicate the aforementioned information audibly, either via a speaker of the computer 104, or via a speaker of a man-machine interface of the vehicle 100, when the computer 104 can communicate with the ECU 107 described below.
- the vehicle 100 comprises a control unit 107 of the vehicle 100, such as a centralized control unit of the ECU type, for “Electronic Control Unit” in English.
- the ECU 107 can also exchange data with the computer 104 according to certain embodiments of the invention, in particular to provide test measurements in synchronization with the data transmitted from the camera 103 to the computer 104.
- the vehicle 100 may also include its own human machine interface, or HMI, 106 capable of transmitting data unidirectionally to the driver of the vehicle, or, preferably, of exchanging data bidirectionally with the driver .
- HMI human machine interface
- No restrictions are attached to the HMI 106 of the vehicle 100 which may include a screen, such as a touch screen, a set of one or more buttons, a speaker, a microphone, a vibration system of the steering wheel, etc.
- the approval system may further comprise a screen 105 external to the data processing device 104, which is functionally connected to the data processing device 104, by a wired connection or preferably by a wireless connection .
- the data processing device 104 can transmit images or a video stream comprising a visual indicator identifying the position of the accelerator pedal 101, and identifying the target position or the target route.
- the transmitted video stream can in particular identify, in real time, the position of the accelerator pedal 1, which is displayed on the screen 105.
- the external screen 105 can thus be advantageously installed in the motor vehicle 100 so as to allow for the driver to follow the path of the accelerator pedal 101 and thus facilitate the achievement of the target position 201.3 or the target path 202.2 by the driver.
- the external screen 105 can in particular be installed on the dashboard or on the driver's windshield, so as to allow the driver to follow the path of the accelerator pedal 101 while concentrating on other driving maneuvers , changing gears, rotating the steering wheel, and observing the driving situation in front of the vehicle 100.
- the system may further comprise a light device 109 capable of illuminating the accelerator pedal 101, and in particular the surface of the accelerator pedal 101 comprising the marker 102, so as to facilitate the identification and monitoring of the marker 102 in the image(s) acquired by the camera 103.
- Figure 3 is a diagram which illustrates the steps of a vehicle approval process according to certain embodiments of the invention.
- the method may comprise a preliminary phase 300 comprising the following steps 301 to 303.
- the marker 102 is arranged on the accelerator pedal 101 of the vehicle 100 to be approved and the camera 103 is installed in the vehicle 100, as well as optionally the associated communication interface 108, such as described previously.
- the lighting device 109 can also be installed inside the vehicle.
- a wireless communication link can also be established between the computer 104 and the camera 103, in particular via the communication module 108.
- a first image identifying the marker 102 arranged on the accelerator pedal 101 when it is in the rest position 201.1 is received by the computer 104 from the camera 103.
- an instruction can be given to the driver not to press the accelerator pedal 101.
- the computer can thus store a correspondence between the position of the marker in the first image and the rest position
- an instruction can be given to the driver to press as much as possible on the accelerator pedal 101, without however exceeding the maximum position 201.2 and reaching the downshift position by kickdown.
- the computer 104 can thus store a correspondence between the position of the marker 102 in the second image and the position of maximum acceleration.
- Steps 302 and 303 thus make it possible to calibrate the certification system in order to be able to detect in the images the position of the accelerator pedal 101 and to be able to compare it with the target position.
- the method further comprises a current phase 310 which may include steps 311 to 324 described below.
- an operator can define at least one approval criterion based on at least one test measurement obtained in a given test situation, defining in particular a target position 201.3 of the accelerator pedal, or a target path of the accelerator pedal, as well as a given path of the vehicle.
- the given route of the vehicle can be a predetermined route, for example a straight or curved line over several tens of meters, for example over 20 meters.
- the given route can define a starting position and an arrival position of the vehicle.
- several criteria can thus be defined, for several target positions determined randomly or not. The vehicle 100 must therefore validate each of these criteria to be approved. No restrictions are attached to the test measurement, which can be a sound intensity measurement for example.
- the approval criterion can thus define a test threshold below which the sound intensity measurement must be lower for the given target position 201.3, to approve the vehicle.
- Such sound measurements can be acquired by a microphone, or a system of microphones, connected to another computer not shown, such as a computer in a control room.
- Other test measurements can be provided alternatively or in addition, such as engine measurements obtained by the ECU 107 and transmitted to the computer 104 for example or to the control room computer.
- the approval begins with a first approval criterion corresponding to a first test situation defining a first target position, or a first target path of the accelerator pedal 101.
- the software stored and executed on the computer 104 can then be configured with the first target position.
- the first test of the approval procedure then begins.
- the driver therefore brings the vehicle to the starting position of the given vehicle route to begin the test.
- the first test begins once the vehicle reaches the starting position.
- a step 313 an image is received by the computer 104 from the camera 103.
- one or more test measurements are received by the computer 104 at a step 314.
- At least one position of the accelerator pedal 101 is determined by the computer 104, in real time, from a position of the marker 102 in the received image.
- step 316 the position of the accelerator pedal 101 is compared with the first target position.
- step 316 may include determining a difference between the position of the accelerator pedal 101 and the first target position.
- a visual indicator representative of the position of the accelerator pedal 101 can be displayed on the computer 104 or on the external screen 105, with the indicator of the target position.
- information, binary or at three levels, indicating whether the deviation is lower than the given threshold can be displayed.
- an audible signal can be produced to indicate if the deviation is less than the given threshold.
- Such a sound signal can be produced by the computer 104, or can be transmitted by the computer 104 to the ECU 107 for broadcast by the HMI 106 of the vehicle 100.
- a step 318 it is determined, by the computer 104 or by an operator, if the given route of the vehicle is completed, that is to say if the vehicle has reached the arrival position of the given route of the vehicle.
- the method moves to a step 319 during which the driver can adapt the pressure on the accelerator pedal according to the comparison of step 316 and indicators displayed in step 317.
- the first test then continues continuously, and a new image is received from the camera in step 313 to continue the process.
- the driver is not capable of adapting the support to each image reception of step 313, but, in practice, after several iterations of the method and several repetitions of steps 313 to 319. Indeed, in a video stream, more than 20 images are acquired per second and the driver cannot adapt the support to each image reception.
- the adaptation step 319 may consist of maintaining support for the driver. Otherwise, the driver presses harder or presses less hard to readjust the position of the accelerator pedal and thus allow validation of the first test situation.
- the computer 104 determines in a step 320 whether the first test situation is validated or not. Such a decision may be based on whether the position of the accelerator pedal 104 was held close to the target position long enough during the first test, or whether the target path of the accelerator pedal corresponding to at the first test was carried out. In particular, when the deviation is less than a given threshold over a given duration, it can be considered that the test measurements of step 314 were carried out under the conditions provided for by the first approval criterion, the first situation test is validated and the first test is thus completed. The process then proceeds to step 321.
- the test measurement(s) acquired in step 314 can be processed in a step 321 depending on the first approval criterion to approve or not the vehicle.
- the test measurement can be compared to the test threshold, and an approval decision can be made based on this comparison.
- the approval decision can take into account several comparisons of step 321, the current phase 310 of the method 300 being iterated as described in the following.
- the processing of step 321 is thus only implemented if the first test is considered completed, that is to say that the test measurements obtained in step 314 have been carried out in the associated test situation. to the first criterion approval.
- the implementation of step 321 is therefore dependent on the comparison results of step 316 obtained for the different images.
- step 320 If the first test is not validated in step 320, the driver must repeat the first test and the process returns to steps 313 and 314.
- step 322 following step 321 it is determined by the computer 104 or by the approval team, whether other approval criteria than the first approval criterion have been defined at step 311. If this is the case, a second approval criterion is considered in step 324, and the software executed on the computer 104 is configured according to a second test situation identifying a second target position , or a second target route, associated with the second approval criterion. Steps 313 and following are thus iterated for the second target position or for the second target route. If no other approval criteria has been defined in step 311, the process ends at step 323.
- Step 321 is shown as being carried out before step 322 in Figure 3.
- a partial approval decision can be obtained in step 321, a final approval decision being obtained when all the tests have been carried out.
- a single decision is made at step 322, after all the tests have been carried out, and in this case step 321 takes place between steps 322 and 323.
- the method according to the invention is particularly advantageous when several tests in several target positions must be carried out successively. Indeed, the solutions of the prior art providing for example the use of a wedge dedicated to each target position, require calibration of the approval system for each test. On the other hand, according to the invention, once the camera and the marker are installed, the transition from one test situation to another, therefore from one approval criterion to another, only requires redefining the position target on the computer 104, which is much faster than the solutions of the prior art.
- Figure 4 shows the structure of a data processing device 104 according to certain embodiments of the invention.
- the data processing device 104 is preferably a computer, such as a laptop.
- the device 104 comprises a processor 401 configured to communicate unidirectionally or bidirectionally, via one or more buses or via a direct wired connection, with a memory 402 such as a “Random Access Memory” type memory, RAM, or a “Read Only Memory”, ROM, or any other type of memory (Flash, EEPROM, etc.).
- memory 402 may include several memories of the aforementioned types.
- the memory 402 is capable of storing, permanently or temporarily, at least some of the data used and/or resulting from the implementation of the method according to the invention illustrated with reference to Figure 3.
- the memory 402 may be able to store, during step 202, at least temporarily, the images from the camera 103, the test measurements, the rest position 201.1 and the maximum acceleration position 201.2, the target positions and /or target routes.
- the target positions and target paths can be indicated by a user via a human machine interface, HMI, 406 of the device 104.
- the HMI 406 which preferably includes a screen, which can be touchscreen, and a keyboard.
- the HMI 406 may include keys, a microphone associated with a voice recognition module, a vibration system, or any other user interface.
- the processor 401 is able to execute instructions, stored in the memory 402, for the implementation of the steps of the current phase 310, with the exception of step 319 implemented by the driver, as well as steps 301 and 302 of the preliminary phase 300, of the method according to the invention, described with reference to Figure 3.
- the processor 401 can be replaced by a microcontroller designed and configured to carry out the aforementioned steps of the method according to the invention.
