Abstract

This application relies on terminology found in the Vehicle State Detection (STATE) patent and describes methods of detecting acceleration, deceleration, accidents and cornering operational states, which we will also call vehicle dependent states, and vehicle independent states, triggered when the portable device is moved independently of movement of the vehicle. These methods enhance classification of driving behavior.

Claims

1. The method of detecting the condition of a vehicle turning, comprising estimating an angle of how closely a rotation vector is aligned with a gravity vector.

2. The method of claim 1 further comprises estimating the probability of the vehicle turning as a function of the angle between the rotation vector and the gravity vector.

3. The method of detecting a direction of a speed change vector, comprising:

a. detecting a condition of a vehicle turning;

b. detecting a movement vector during the turn;

c. estimating the angle between movement vector and speed change vector;

d. determining that the speed change vector is acceleration vector if the estimated angle below certain threshold and determining that the speed change vector is deceleration vector if the estimated angle is above certain threshold.

4. The method of claim 3 further comprises estimating the probability of the speed change vector to be an acceleration or deceleration vector—

as a function of the angle between the speed change vector and the movement vector.

5. The method of performing one or more actions on a portable device carried by an individual, comprising:

a. monitoring at least one operation indicator transparently to the individual, wherein the at least one operation indicator is created by an on-board component of the device when the portable device is located inside a vehicle;

b. detecting when the at least one operation indicator meets one or more predetermined criteria;

c. determining entirely or in part the following states based on the one or more predetermined criteria;

i. one or more vehicle independent states;

ii. one or more vehicle dependent states.
