Smart system for determining driving behaviour of driver

A system (1) to efficiently determine a driving behaviour of a driver driving a vehicle, the system comprising:

• a 3-axis accelerometer (2) placed inside the vehicle, the 3-axis accelerometer (2) is adapted to generate an accelerometer data (3) related to an acceleration of the vehicle at each time instant;
• a direction sensor (4) placed inside the vehicle, and adapted to generate a direction data (5) related to a direction in which the 3-axis accelerometer (2) is travelling;
• an orientation sensor (6) placed inside the vehicle, and adapted to generate an orientation data (7) related to an orientation and an angular velocity of the 3-axis accelerometer (2);
• and
• a processing unit (8) adapted to process the accelerometer data (3), the direction data (5) and the orientation data (7), and to re-calibrate the accelerometer data (3) to generate a calibrated accelerometer data (9) where the 3 axes of accelerometer are aligned with 3 axes of the orientation of the vehicle,
• wherein the calibrated accelerometer data (9) corresponds to the spatial reference frame of the vehicle, used in determining the driving behavior of the driver of the vehicle.
