Title: System for the personalized automatic control of gear changes in a motor vehicle provided with servo-assisted gears

Abstract: The system includes a memory in which curves are stored which define the conditions for each gear change, corresponding to at least two reference styles of driving, sensors for operating parameters of the motor vehicle, and second processing devices set up to estimate the value of a first index which identifies the kind of driving of the motor vehicle and, respectively, the value of a second index which defines the manner or style of driving of the driver, and a processing and control unit. This unit is set up to perform a learning procedure in which it acquires and memorizes the value of the second index corresponding to the manner or style of driving of the driver during a test drive with manual control of the gears, and generates and memorizes maps of modified curves defining the conditions for the gear changes according to a personalized style of driving from among the said reference methods, and an automatic control procedure in which it controls actuators in order automatically to effect the gear changes based on the modified curves generated during the learning procedure.
