Definitions
- the direction of a vehicle between these at least two locations can be determined from location data acquired along at least two successive locations along the path. Alternatively or additionally, the direction of the vehicle is determined using a
- Changes in the direction of a vehicle as a result of turning off a road can be detected, which are important for the reconstruction of the path of the vehicle in a control center and for the assignment of the vehicle path to a digital map in a control center
- the method according to the invention can be implemented in a terminal in a terminal or in a program
- short-term angle fluctuations of the vehicle can be filtered out by defining a stability criterion that implies this or by stability criteria. For example, driving around a parked vehicle or a directional fluctuation due to drunkenness of the driver can be suppressed.
- the definition of a support point within a curve can also be avoided below the angle limit value (here 45 °) and above an angle stability limit value of 10 °, for example, and in this case an unstable state, which represents a relatively rapidly swiveling direction, can be defined.
- an unstable state the definition of a support point can generally be omitted
- an unstable state of the vehicle can be defined if the
