• 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.
