A method for determining an optimized torque distribution (AWDS, RLS, RLS') to the wheels (2, 3) of a road vehicle; the road vehicle comprising an actuator (A, 5) for each of the wheels (2, 3) to independently control the torque; the method comprising the steps of: - determining once a first table of torque distribution between a front axle and a rear axle of the road vehicle, which provides a first curve (DC') representative of a first factor (AWDS) of torque distribution as a function of the variation of the longitudinal dynamics (Ax, Vx) of the road vehicle; - determining once a second (ST") and a third (ST") torque distribution tables between a right (2, 3) wheel and a left (2, 3) wheel, respectively, of the rear axle and the front axle of the road vehicle, wherein the second and third tables (ST", ST''') provide a second and third curves (DC", DC′′′) respectively representative of a second and a third (RLS') torque distribution factor as a function of variation of the longitudinal dynamics (Ax, Vx) of the road vehicle; - detecting the current longitudinal (Ax, Vx) dynamics of the road vehicle while driving through a curve; - using the first, second and third tables (ST', ST", ST") to determine a present value of the first (AWDS), second and third (RLS') distribution factors respectively, based on the present longitudinal (Vx) speed and the present longitudinal (Ax) acceleration of the road vehicle; wherein the first (AWDS), second and third (RLS') distribution factors are configured to maximize, for the current longitudinal speed (Vx) and current longitudinal acceleration (Ax), the lateral acceleration (Ay) of the road vehicle; the method being characterized in that it comprises, in order to calculate a point of the first, second or third curve (DC', DC", DC′′′), the step of determining a point of maximum performance by imposing a steering angle and an attitude angle (β) of the road vehicle and calculating the maximum lateral acceleration (Ay) of the road vehicle under said conditions; wherein the point of maximum performance is determined by the intersection of a first curve iso of the steering angle and a second curve iso of the attitude angle. - determining once a first table of torque distribution between a front axle and a rear axle of the road vehicle, which provides a first curve (DC') representative of a first factor (AWDS) of torque distribution as a function of the variation of the longitudinal dynamics (Ax, Vx) of the road vehicle; - determining once a second (ST") and a third (ST") torque distribution tables between a right (2, 3) wheel and a left (2, 3) wheel, respectively, of the rear axle and the front axle of the road vehicle, wherein the second and third tables (ST", ST''') provide a second and third curves (DC", DC′′′) respectively representative of a second and a third (RLS') torque distribution factor as a function of variation of the longitudinal dynamics (Ax, Vx) of the road vehicle; - detecting the current longitudinal (Ax, Vx) dynamics of the road vehicle while driving through a curve; - using the first, second and third tables (ST', ST", ST") to determine a present value of the first (AWDS), second and third (RLS') distribution factors respectively, based on the present longitudinal (Vx) speed and the present longitudinal (Ax) acceleration of the road vehicle; wherein the first (AWDS), second and third (RLS') distribution factors are configured to maximize, for the current longitudinal speed (Vx) and current longitudinal acceleration (Ax), the lateral acceleration (Ay) of the road vehicle; the method being characterized in that it comprises, in order to calculate a point of the first, second or third curve (DC', DC", DC′′′), the step of determining a point of maximum performance by imposing a steering angle and an attitude angle (β) of the road vehicle and calculating the maximum lateral acceleration (Ay) of the road vehicle under said conditions; wherein the point of maximum performance is determined by the intersection of a first curve iso of the steering angle and a second curve iso of the attitude angle.
