A method for the performance-enhancing driver assistance of a road vehicle driven by a driver and provided with at least two drive wheels driven by at least one electric motor connected to a corresponding vehicular battery pack; the method comprises the steps of defining a dynamic model of the road vehicle; determining a route of a track travelled by the road vehicle; calculating, as a function of the dynamic model of the road vehicle and of the route, a convenience index relative to the use of energy of the vehicular battery pack by the electric motor; subdividing the route (R) into a plurality of sectors assigning to each a relative value of the calculated convenience index; delivering electrical power to the drive wheels according to the value of the convenience index assigned to each sector of the route.

Method for the performance-enhancing driver assistance of a road vehicle

A method for the driver assistance of a road vehicle; the assistance method comprises the steps of: determining an actual steering angle of the front wheels; determining a desired steering angle of the front wheels; and changing the servo-assistance torque applied by a servo-assistance device to a steering system based on the actual steering angle and on the desired steering angle, so that the servo-assistance torque that is applied when a steering wheel is rotated in a first direction to change the actual steering angle causing it to approach the desired steering angle is greater than the servo-assistance torque that is applied when the steering wheel is rotated in a second direction, which is opposite to the first direction, to change the actual steering angle causing it to distance itself from the desired steering angle.
