- the messages transmitted by the interface 200 are written and / or voice messages and / or in the form of light or sound signals.
- the messages sent here are voice messages synthesizing, for each particular driving situation, the driving habits of the driver deviating from the corresponding reference habits.
- Such messages could for example be "In a situation of overtaking, you tend not to control your blind spot.
- Voice messages can also be in the form of advice to the driver to correct bad driving habits.
- Such advice could for example be “before turning to the right, think to control your environment on the right, on the left, then again on the right", or “be sure to trigger your hazard warning lights in the event of a slowdown in front of you, to warn the users arriving behind you ".
- control unit 30 of the tracking device 100 is also programmed to inform the driver of an evolution of his driving habits over time, for example after one week of driving, after a month of driving. , or after one year of driving.
- the memory 40 of the tracking device 100 is adapted to store the detected differences between the values of the recorded behavioral parameters and the reference values for each determined driving situation.
- the control unit 30 is then adapted to detect improvements or deteriorations in certain driving habits over time.
- control unit is programmed to compare the differences that occurred during particular driving situations over different periods of time, for example from one week to another or from one month to another.
- control unit 30 being programmed to evaluate the difference existing between each registered behavior parameter value and each corresponding reference value, said control unit 30 is adapted to store in the memory 40 the numerical value of this gap.
- the control unit 30 can then be programmed to compare in time, the differences between the value of each registered behavior parameter and the corresponding reference value.
- the interface 200 is also adapted to provide a summary of changes in the driving habits of the driver over time.
- the tracking device 100 further comprises an identification system 50 of the driver (see Figure 1).
- This identification system 50 of the driver is adapted to determine an identifier of the driver.
- this identification system 50 allows the tracking device 100 according to the invention to be adaptable to several drivers of the same vehicle.
- the identification system 50 is a system by facial recognition of the driver.
- the identification system 50 is adapted to communicate with the memory 40 and the control unit 30 of the tracking device 100 by means of the identifier.
- each behavioral parameter associated with the driving habits of the identified driver is recorded in the memory in relation to the identifier of said driver.
- the memory 40 can thus be adapted to store several sets of behavioral parameter values corresponding to several different conductors.
- the control unit 30 is then adapted to analyze the driving habits associated with each identified driver.
- the difference threshold value associated with each type of behavioral parameter and the repeat limit value are then specific to the identified driver.
- the threshold and limit values can be chosen very low, or lower than the values mentioned above, so as to increase the sensitivity of the tracking device 100.
- the threshold and limit values can be chosen higher to reduce the sensitivity of the tracking device.
- control unit 30 is adapted to send a message to the identified driver.
- the control unit 30 is thus programmed to follow the evolution of the driving habits of each of the potential drivers of the vehicle.
- the tracking device it is possible to increase the sensitivity of the latter.
- the sensitivity increase can be imposed when the driver takes a known path detected by the GPS system of the tracking device.
- the tracking device is adapted to implement a method of monitoring the driving habits of the driver of the transport vehicle which comprises the following steps:
- step c) for each driving situation determined in step c), comparing said driver behavioral parameter value recorded during said driving situation with a reference value corresponding to reference driving habits for that driving situation (E5) , and
- e) issuing a warning signal to the driver when the value of the behavioral parameter associated with the driver's driving habits for the particular driving situation is different from the reference value corresponding to the driving habits of reference for that driving situation , repeatedly.
- control unit 30 detects in step d) whether in fact a difference has occurred between the driver's driving habits and the reference driving habits (E6), and then implements step e) in recording in the memory 40 (E7) the difference detected at the step d) for the driving situation determined in step c). The control unit 30 then monitors whether, when the driving situation is determined again, a difference occurs again (E8).
- the control unit 30 finally alerts the driver (E9) when a difference is detected for the determined driving situation, repeatedly.
