Telematics platform

Database and software system platform calculated on work with more than 1 million users connected to it. Due to the storage and processing on the  Amazon Cloud server all this became possible. Installed environment can be reconstituted for new users in 24 hours. In the aggregate this helps to avoid problems of integration speed  in the new operating environment.

Data

Vehicle data collected with the GPRS get into telematics platform and processed by “cloud” servers. The ability to bring together data from different sources into one unit in order to increase their value and to carry out cross-checks of accuracy is an advantage of the system in this area.


Obtained data includes information about:

  • Vehicle Coordinates;
  • distance covered;
  • underway time;
  • speed;
  • acceleration;
  • braking;
  • sideward acceleration;
  • engine speed;
  • RTA;
  • fault code.

Telematic platform can receive data at different intervals, depending on customer requirements.

RTA data transmission:

  • The insured event primary notification/ RTA registration support –  at  the moment of receiving the insured event primary notification 2 data files automatically compiled and arrives to the data server;
  • 8.5-second record  of  happening forms within 4.252 seconds before and after sending insured event primary notification signal frequency of 4 Hz. In the signal data transmits latitude, longitude, speed, stud driving, and acceleration of the axes x / y / z g-sensor data.
  • 120-second record of happening forms within 30 seconds before and after sending the  insured event primary notification signal frequency of 1 Hz. In the signal data transmits latitude, longitude, speed, stud driving and the satellite number.
  • Within 3 seconds before and after sending the insured event primary notification signal frequency of 50 Hz forms 6-second record from the accelerometer sensor.

The multisensory method and a high speed data acquisition combination has led to that the device is:

  • identifies RTA with an accuracy more than 90%;
  • allows to view, what affected the vehicle during the collision.

Client mobile applications and WEB- portal to the relevant sections are used to display the processed data.

 

Driver behaviour analysis

Telematics allows you to effectively monitor driver’s manner and style of driving, reduce insurance premiums, save fuel. Driving analysis is personal, related to the driver,   safety and efficiency of the vehicle control overall evaluation.


Factors affecting Driver behaviour analysis:

  • trip characteristics;
  • trip distance;
  • trip duration;
  • trip geofence;
  • dangerous areas;
  • times of Day.

 

Events during the trip:

  • Speed infringement;
  • accelerations;
  • braking;
  • angular acceleration.

Other:

  • Vehicle type;
  • Driver experience;
  • Driver’s age.

During the trip the driver gets penalty points depending on events.

Speeding violations

Acceleration, Braking, Angular acceleration

Points and overspeed threshold are customizable parameters and adjusted during the statistical data handling.

IMPORTANT Great work experience with navigation technology and using of an actual map database, allows precisely estimate the overspeed value at the section, relative to permitted.

Additional customizable impact factors on the penalty points for speed violations:

  • geofence violations;
  • dangerous areas;
  • times of Day;
  • vehicle type;
  • driving experience;
  • weather.

This technology has been developed with the assistance of the world leaders of transport issues practical research field: Loughborough University, Motor Industry Research Association (MIRA), Driver Research Group at Cranfield University.

KEY BENEFITS OF TECHNOLOGY:

  • Using accurate map database to measure the fact and allowed speed excess amount;
  • SYSTEM FLEXIBILITY in Geofence and DANGEROUS AREAS settings;
  • Impact Parameters ADJUSTMENT to the final assessment depending on the received STATISTICAL INFORMATION.

 

Trip Profiling


R-Telematica Telematics platform allows profiling trip data over a certain period of time on the following parameters:

  • Trip durationTrip length;
  • Downtime;
  • Geofences trip distribution;
  • Roads class trip distribution;
  • Trip distribution by light and dark times of day;
  • Trip distribution by day of week;
  • Speed infringement number;
  • Acceleration, braking and lateral acceleration number above the threshold.

The most complete and constantly updated Russian roads database, which includes speed profiles and road classes, permitted maneuvers, the traffic lights locations, speed cameras, pedestrian crossings, speed bumps and dangerous roads data will allow to flexibly configure and distribute trips by GEOFENCES with different degrees of risk getting into RTA.

 

RTA Identification / reconstruction


Solution
RTA identifying improved technology basis on two independent methods of collision detection:

  • The first method assumes use of 3-axis (XYZ) G-sensor (longitudinal, transverse and vertical axis) accelerometer readings basis;
  • The second method based on capturing acoustic waves passing through the vehicle frameIn our case, the RTA identification occurs when both methods – acoustic and G-sensor – confirm the collision.

Traditional methods are based only on the accelerometer range. This creates certain problems to separate accident in real and false: it becomes impossible to determine if received blow is due to adverse environmental factors (speed bumps, road potholes, curb hitting) or a small RTA happened (at low speeds).

As a result of a high speed collision, which entails large energy release, are easily identified. As for the small accident, the system they do not differ them much from the bad driving. The key for insurers will be technology that will be able to distinguish between these two situations.

How it works?

Our technology uses two input signals to identify bumps. Traditional G-sensor based on accelerometer readings technology is complemented by collecting acoustic waves that occur during an accident. Only when both sensors simultaneously record the bump at a predetermined level, system sends an RTA report.

Driver rarely will not distinguish the sound that occurs as a result of contact of the trolley from the supermarket with plastic frame front or rear bumpers. A similar sound passes through the whole frame of the vehicle and fixed by sensor. In our case, the energy output is too small and G-sensor identifies a minor collision. All in all, technology will give the result: “RTA is not identified (possible chipped paint!)”.

Strong bump obtained in a collision with a large body, such as another vehicle, generates a pronounced acoustic waves. In addition, a bump pass the vehicle frame allowing high profile acceleration identification.

This same pattern, for example, will be reconstituted in a low acceleration collision. In case of low speed RTA there is also happens a burst of G-sensor readings and acoustic sensor. That means that permissible threshold values set to maximum sensitivity. This can not be achieved using only G-sensor.

Software set more accurate, detailed G-sensor setting and an acoustic output. Overall and smaller vehicle can have different settings, including the punch strength and duration.

Same way one can calibrate the acoustic sensor and accelerometer sensor. When installing these devices need to specify their location in the vehicle, so the sensors can be oriented (where is the front, back of the car). The axes X, Y and Z are aligned automatically.

Acoustic sensor can distinguish sounds that makes the car itself (though they sound like an accident), so loud music or children fighting in the back seat will not cause an alarm sensor activation.

Effectiveness

Device test  and system check-up were based on real conditions. The main objective in this case was calibration test, system verification to reject false signals, and low speeds RTA fact finding.

Data transfer for the reconstruction of the RTA:

  • Insured event / accident registration maintenance primary notification – at the moment of getting insured event primary notification two data file automatically compiled and enter the server data;
  • 8.5-second record of happening forms within 4.252 seconds before and after sending insured event primary notification signal frequency of 4 Hz. In the signal data transmits latitude, longitude, speed, stud driving, and acceleration of the axes x / y / z g-sensor data.
  • 120-second record of happening forms within 30 seconds before and after sending the insured event primary notification signal frequency of 1 Hz. In the signal data transmits latitude, longitude, speed, stud driving and the satellite number.
  • Within 3 seconds before and after sending the insured event primary notification signal frequency of 50 Hz forms 6-second record from the accelerometer sensor.

Apart from just listed, using sensors can be ascertained: whether timely manner brake has been used at the road accident; the position was the throttle just before the accident; whether fastened seatbelts.

Testing

The technology was intensively testedA certain number of devices have been connected to the program and installed into vehicles that were moving in a controlled environment. Then the cars were exposed to series of hits at low speed (simulating silly situations) to check the device operation and ensure that the signal about minor accident is sent.

The laboratory instruments and cameras were installed in the cars to record all the parameters of the test in detail . Output data was transmitted “over the air” to the remote servers. The functionality of the system was tested in a complete sequence of actions. The cars drove through the artificially created road obstacles, to ensure that the sound waves passing through the suspension of the vehicle, are not identified as “false” accidents.

Results
Testing experience in “real road conditions” showed that the system successfully rejects “false” accident signals. Which is valuable in combination with other data.

Determination accuracy of RTA reaches 96%. Apart from just listed, using sensors can be ascertained: whether timely manner brake has been used at the road accident; the position was the throttle just before the accident; whether fastened seatbelts

 

Remote technical diagnostics

The system allows to define different vehicle fault before they cause serious damage.

Functioning of the system is performed via OBD device (an active link to the device) inserted into the diagnostic car socket and provides a vehicle state overview.

In case of remote diagnostics system breakdown, it informs about the incident the client and the response team, which connects to the diagnostics vehicle module software and identifies the malfunction.The software can transfer through the chain data about the exact location of the disabled vehicle to the service team armed with the necessary tools and spares which goes to the vehicle location by the shortest route on request. If the vehicle repair can not be implemented on the spot, the vehicle position is transmitted to the evacuation service team.


The system enables to read the following parameters:
  • mileage;
  • engine speed;
  • fuel level;
  • fuel consumption (instantaneous and route);
  • coolant temperature;
  • oil pressure;
  • ABS Status;
  • interservice intervals;
  • Indicator lamps readings on the dashboard;
  • accelerator pedal position;
  • brake pedal position;
  • seatbelt status;
  • battery charge;
  • error: reading and interpretation.
