Intake system for a supercharged internal combustion engine, comprising an intake duct with a cooling line comprising a high temperature cooler and a lower temperature cooler arranged in series along the intake duct, and a by-pass branch arranged in parallel with the low temperature cooler, and a heating line with a heater. The heating line is arranged in parallel with the cooling line. The intake system is configured so that it may be modulated between a heating mode, where the gaseous intake fluid is heated through the heater, and a cooling mode, where the gaseous intake fluid is cooled through at least one of the high temperature cooler and the low temperature cooler.

1. Intake system for a supercharged internal combustion engine of a motor vehicle, comprising: an intake duct having a first end connectable to a supercharger compressor and a second end connectable to a plurality of cylinders of the engine for supplying a gaseous intake fluid to said cylinders, wherein said intake duct includes a cooling line comprising: a high temperature cooler and a low temperature cooler arranged in series along said intake duct and supplied with a cooling fluid for cooling the gaseous intake fluid, said cooling fluid being supplied by a feed system onboard the motor vehicle; anda by-pass branch arranged in parallel with said low temperature cooler, said bypass branch and said low temperature cooler being selectively connected to an outlet of said high temperature cooler;said intake system further comprising a heating line having an electric heater for heating the gaseous intake fluid, said heating line being arranged in parallel with said cooling line, wherein said intake system is configured so that it is modulatable between a heating mode, where the gaseous intake fluid is heated through said heater, and a cooling mode, where the gaseous intake fluid is cooled through at least one of said high temperature cooler and low temperature cooler,wherein the intake system further comprises valve devices arranged along said heating line and cooling line for modulating the flow of the gaseous fluid through them, andwherein said valve devices comprise a first valve device connected to an outlet of the heater and arranged downstream of the heater, a second valve device arranged on the by-pass branch, and a third valve device connected to an outlet of the low temperature cooler and arranged downstream of the low temperature cooler,said intake system further comprising a control unit programmed for modulating the intake system between the heating mode and the cooling mode depending on driving conditions of the vehicle determined by means of a plurality of sensors associated with the control unit,wherein said sensors comprise an outlet temperature sensor for providing a signal indicating the temperature of the gaseous intake fluid downstream of the intake system, a speed sensor for providing a signal indicating a vehicle speed, and an accelerator sensor for providing a signal indicating an acceleration requested for the vehicle. 2. System according to claim 1, wherein said heater, high temperature cooler, low temperature cooler and, optionally, said valve devices are integrated in a single conditioning module. 3. System according to claim 1, wherein said control unit is an engine control unit. 4. System according to claim 1, wherein said sensors further comprise an inlet temperature sensor for providing a signal indicating the temperature of the gaseous intake fluid at an inlet of the intake duct, downstream of the supercharger compressor.
