The need of containing the vehicle mass increment, which is common in all sport cars, and the limited space under the engine bonnet made the designers to think about an innovative driveline scheme. In the paper a control system for the handling of an innovative AWD vehicle has been presented. The algorithms for the control of each part of the powertrain has been illustrated and correlated to the handling response. The control system has been tested simulating both ISO and not ISO maneuvers. Beside, many laps on a high speed circuit and a mountain track for different road friction level to predict the centre clutch stress. The system derives from a rear wheel drive architecture with a semi-active differential, to which has been added a controlled wet clutch that directly connects the front axle and the engine crankshaft. This device allows distributing the drive torque between the two axles, according to the constraints due to kinematics and thermal problems. It can be easily understood that in this device the torque distribution doesn't depend only from the central clutch action, but also from the engaged gear. Because of that the central clutch controller has to consider the gear position too. The control algorithms development was carried on using a vehicle model which can precisely simulate the handling response, the powertrain dynamic and the actuation system behaviour. A right powertrain response required the development of a customized library in Simulink. The approach chosen to carry on this research was the one used in automotive industry nowadays; an intensive simulation campaign was executed to realize an initial controller design and tuning.
