<p>A circuit arrangement (10) is disclosed for controlling the passenger compartment and bodywork devices of a vehicle, having a plurality of command inputs (INL, INW, INB) adapted to receive commands for activating the devices, and a plurality of driving outputs (D1, D2, D3) adapted to emit signals for driving the devices so as to implement the input commands received, said circuit arrangement (10) comprising a control unit (12) arranged to recognize the input commands received and generate respective output driving signals so as to establish a command path in a normal operating condition. The circuit arrangement (10) comprises a limp-home emergency circuit (LH) including a plurality of connection branches (B 1 , B 2 , B 3 ) adapted to couple the command inputs (INL, INW, INB) to respective driving outputs (D1, D2, D3) by means of respective alternative command paths which bypass the control unit (12), said connection branches (B 1 , B 2 , B 3 ) comprising a circuit arrangement (25, 35, 40) for enabling alternative command paths depending on recognition of a malfunction operating condition of the control unit (12).</p> |
