Abstract

A powertrain control system for management and supervision of engine and servo-assisted gearbox control modules is arranged for determining the power to be applied to the drive wheels of the vehicle as a function of signals indicative of commands imparted by the driver, of the engine and gearbox state parameters and of possible requirements from the engine and gearbox control modules and supplementary on board vehicle traction/drive control systems; calculating data indicative of the torque to be delivered at the engine drive shaft, the torque transmissible by the clutch and the required transmission ratio, as a function of the determined value of the power to be applied to the drive wheels, of the state parameters and of the requirements of the engine and gearbox control modules and the traction/drive control systems; and transmitting the calculated data as signals to the engine and gearbox control modules.
