Abstract: An air-conditioning system for a vehicle, that includes a module for controlling the air-conditioning group for adjusting the temperature inside the passenger compartment to a setpoint temperature, the control module being capable of correcting the temperature adjustment in the passenger compartment based on a received sunshine value in the passenger compartment. The system further includes a mechanism correcting the sunshine value to improve the correction of the temperature adjustment inside the passenger compartment particularly in cloudy conditions.

Abstract: The invention relates to a vehicle air-conditioning system (10) capable of operating with n predetermined automatic regulation modes, the system comprising a calculator (1) capable of determining, as a function of a selected automatic mode (MODS), a blown-air temperature value (QAS), a ventilation flow rate value (DEB) and a distribution control value (REP) in order to control a heating, ventilation and air-conditioning (HVAC) unit (2) capable of regulating the temperature (QHAB) inside a passenger compartment (3) towards a setpoint temperature (?c), characterized in that the blown-air temperature value (QAS) for the selected automatic mode (MODS) that is applied to the HVAC (2) is determined as a function of the ventilation flow rate value of the selected mode (DEBMODS), of a thermal power value for the selected automatic mode (PMODS), and of a heat exchange coefficient value (CECH).
