MOTOR VEHICLE DRIVER ASSISTANCE METHOD

The invention relates to a driver assistance method for a motor vehicle of interest equipped with a driver assistance system (3) and travelling in a driving area, comprising the steps of: detecting, by the system (3), at least one third-party vehicle present in the environment of the vehicle of interest based on measurements delivered by at least one exteroceptive measurement sensor (2) installed on-board the vehicle of interest; predicting, by the system (3), a trajectory associated with the detected third-party vehicle; and determining, by the system (3), a safety area for the vehicle of interest, based on the projected trajectory and the current movement parameters of the vehicle of interest. Vehicle movement models dependent on a set of parameters representative of limitations of the kinematic performances associated with the vehicles are used in the prediction and determination steps. According to the invention, the value of at least one of the parameters of said set is dynamically modified by the system (3) depending on at least one additional piece of information transmitted to the system (3) by at least one external source (1, 2, 4) installed, or not, on-board the vehicle of interest.
