Abstract

An electronic logging and track detection system for mobile telematics devices and method are provided. In particular, an electronic logging and track detection system and system for mobile telematics devices, as smart phones and/or mobile cellular phones is proposed, which tend to change their sensing and measuring orientation and direction in respect to the main direction of movement/motion or moving sense, as for example given by a person with proper motion holding a mobile phone within a moving vehicle. Instantaneous movement telematics data are measured by and logged from sensors of the mobile telematics devices and trips and/or trip-segments based on the instantaneous movement sensory telematics data are automatically identified and detected at least by the telematics sensors comprising an accelerometer sensor and a gyroscope sensor and a Global Positioning System sensor. The telematics devices comprise one or more wireless connections acting as a wireless node within a corresponding data transmission network by means of antenna connections of the telematics device.

First claim

The invention claimed is:

1. An electronic logging and track detection system comprising:
a plurality of mobile telematics circuitry, wherein telematics data are measured by and logged from sensors of the mobile telematics circuitry and trips or trip-segments based on the telematics data are automatically identified and detected, wherein the telematics data comprise usage-based, user-based, or operation-based sensory data, and wherein the mobile telematics circuitry comprise one or more wireless connections, each of the mobile telematics circuitry acting as a wireless node within a corresponding data transmission network by antenna connections of the mobile telematics circuitry, wherein
the plurality of mobile telematics circuitry capturing the telematics data from the sensors are connected to a dynamic trip-detection telematics circuit, wherein a data link is set by the wireless connection between the dynamic trip-detection telematics circuit transmitting at least telematics data based on captured usage-based, user-based, or operational-based sensory data from the mobile telematics circuitry to the dynamic trip-detection telematics circuit, and wherein the sensors at least comprise an accelerometer sensor, a Global Positioning System (GPS) sensor, or a gyroscope sensor,
for trips or trip-segments identification, each measurement of instantaneous movement telematics data is captured and assigned to a measured timestamp by polling circuitry, wherein the measurements of the telematics data are provided in an interval sensing within a defined time interval between two sensing steps,
by adhoc classifier circuitry, a motion status signal is dynamically generated automatically triggering on significant movements of the mobile telematics circuitry and providing a measure for discriminating between dormant phase and sensing phase with streaming signals by the sensors, wherein the sensing phase is automatically interrupted, if the measured status signal switches to no significant movements of the mobile telematics circuitry,
at an end of the sensing phase of time sequential telematics data sensing, the polling circuitry assesses status of the mobile telematics circuitry determining when the telematics data sensing should be triggered again, wherein the polling circuitry exploits a continuous cyclic background running of the adhoc classifier circuitry, providing a variable waiting time, in order for the sensing phase to become again active,
the adhoc classifier circuitry comprises a data buffer buffering a defined range of contiguous sets of motion status signals from the captured telematics data, removing spurious assignment by triggering only commonest motion status signals of a given set of the data buffer by their highest frequency based on a majority voting structure of the adhoc classifier circuitry,
the sets of motion status signals, processed by the adhoc classifier circuitry, are transferred to the dynamic trip-detection telematics circuit, wherein points of the sets are automatically assigned to one of defined categories of roads or to a measured distance of the point to the closest road of a specific category by a trip-detection core engine, and wherein in a case of a measured distance, one of the defined categories of roads is only assigned, if a measured distance is triggered within a given threshold value, and
the sets of motion status signals with road-type assigned points are time dependently piped in a trip buffer element of the trip-detection core engine for assessing their membership to a trip or trip segment, wherein to detect when a trip is finished, a trip contiguity is measurably determined over the sets of motion status signals buffered in the trip buffer element measuring a time difference of the timestamp of the last point belonging to buffered preceding set of motion status signals to the timestamp of a first point of the subsequent set of motion status signals, and wherein if the time difference is lower a time threshold value the two sets of motion status signals are assigned to the same trip or trip segment, while otherwise a trip or a trip segment is triggered as finished.

2. The electronic logging and track detection system according to claim 1 , wherein frequencies for which the sensors are logged are 1 Hz for the GPS sensor, 50 Hz for accelerometer sensor or gyroscope sensor.

3. The electronic logging and track detection system according to claim 1 , wherein the polling circuitry triggers an effective sleep of the adhoc classifier circuitry during a logging phase, generating a direct call to the adhoc classifier circuitry once the measured status signal switches to significant movements of the mobile telematics circuitry.

4. The electronic logging and track detection system according to claim 1 , wherein the majority voting structure of the adhoc classifier circuitry is at least based on triggering a winning status of the previous set as basic majority voting structure, wherein if the winning status of a previous package belongs to a current set of winners, than the winning status is confirmed as winner for the current set, while otherwise a random selection from the current set of winners is performed by the adhoc classifier circuitry.

5. The electronic logging and track detection system according to claim 4 , wherein the adhoc classifier circuitry is based on any combination of the majority voting structure.

6. The electronic logging and track detection system according to claim 1 , wherein the majority voting structure of the adhoc classifier circuitry is at least based on triggering a winning status of the previous set as double majority voting structure, wherein if the winning status of a previous package belongs to a current set of winners, than the winning status is selected as winner for the current set, while otherwise a random selection from the current set of winners is performed by the adhoc classifier circuitry, and wherein the selection is performed two-fold in cascade by the adhoc classifier circuitry.

7. The electronic logging and track detection system according to claim 1 , wherein the majority voting structure of the adhoc classifier circuitry is at least based on triggering a winning status of the previous set as selective majority voting structure, wherein if the winning status of a previous package belongs to a current set of winners, than the winning status is selected as winner for the current set, while otherwise a random selection from the current set of winners is performed by the adhoc classifier circuitry, and wherein a selection is performed by the adhoc classifier circuitry in an incremental way only if a current selection is different from the previous one.

8. The electronic logging and track detection system according to claim 1 , wherein the majority voting structure of the adhoc classifier circuitry is at least based on triggering a winning status of the previous set as half-selective majority voting structure, wherein if the winning status of a previous package belongs to a current set of winners, than the winning status is selected as winner for the current set, while otherwise a random selection from the current set of winners is performed by the adhoc classifier circuitry, and wherein a selection is performed by the adhoc classifier circuitry in an incremental way only if a current selection is different from the previous one, and wherein the half-selective majority voting structure is only applied to half of a previous set of the data buffer.

9. The electronic logging and track detection system according to claim 1 , wherein the majority voting structure of the adhoc classifier circuitry is at least based on triggering a winning status of the previous set as time-weight majority voting stru
