METHOD FOR RECOGNIZING THE DRIVING STYLE OF A DRIVER OF A LAND VEHICLE, AND CORRESPONDING APPARATUS

A method for recognizing the driving style of a driver of a land vehicle, of the type that envisages acquiring information on the dynamics of the vehicle from sensors and calculating, as a function of said information on the dynamics of the vehicle, a class of membership of the driving style of the driver. The method comprises the steps of analysing information on the dynamics of the vehicle to start a procedure of recognition of the event that comprises: reconstructing a manoeuvre performed by the driver; identifying the manoeuvre performed, by comparing said displacement time series with models of time series corresponding to pre-determined manoeuvres stored in a database; defining regions in a cartesian plane having as axes a lateral acceleration and a longitudinal acceleration, in particular manifolds; computing cost functionals for the three driving styles; and recognising the driving style, on the basis of said cost functionals.

Using driver assistance to detect and address aberrant driver behavior
12005906 · 2024-06-11 · ·

The technology relates to identifying and addressing aberrant driver behavior. Various driving operations may be evaluated over different time scales and driving distances. The system can detect driving errors and suboptimal maneuvering, which are evaluated by an onboard driver assistance system and compared against a model of expected driver behavior. The result of this comparison can be used to alert the driver or take immediate corrective driving action. It may also be used for real-time or offline training or sensor calibration purposes. The behavior model may be driver-specific, or may be a nominal driver model based on aggregated information from many drivers. These approaches can be employed with drivers of passenger vehicles, busses, cargo trucks and other vehicles.

System, method, and apparatus for classifying an occupant of a vehicle seat

A method for determining an occupant class for a vehicle seat includes obtaining, via first and second seat weight sensors, first and second seat weight indications for the vehicle seat. The first seat weight sensor is located on the lateral side of the vehicle seat at a front location on the vehicle seat. The second seat weight sensor is located on the lateral side of the vehicle seat at a rear location on the vehicle seat. The method also includes obtaining a vehicle acceleration value from a vehicle acceleration sensor. The method also includes determining a raw weight on the vehicle seat as twice the sum of the first and second seat weight indications, and determining a filtered weight based on the raw weight. The method further includes determining the occupant class based on the filtered weight in response to the vehicle acceleration value being less than a predetermined value.
