System and method for driving style driver identity determination and control of vehicle functions
A system for controlling a vehicle based on a driving style determined driver identity includes sensors that capture driving-style-based data characterizing a driving style of an unknown driver. The system also includes a control unit that determines a driving style vector of the unknown driver from the captured driving-style-based data. The control unit compares the driving style vector of the unknown driver to driving style vectors of a plurality of known drivers to generate a similarity score for each of the plurality of known drivers. The control unit ranks the plurality of known drivers according to their respective similarity scores, and identifies the unknown driver as at least one of the ranked known drivers based on the respective similarity scores. The control unit controls vehicle systems based on the identification of the unknown driver.
