<p>An automobile integrated wiring system has a central control unit (10) adapted to act upon operator control instructions. The central control unit (10) is arranged to provide output signals over a transmission path (A) to a plurality of controllable peripheral devices (20, 30) each of the peripheral devices being arranged to perform a control function of the automobile. At least one of the peripheral devices (20) includes detecting means for detecting an abnormality in the central control unit (10) and means (1 - 4) adapted to accept operator control instructions over the transmission path when the central control unit (10) is detected to have an abnormality so that an appliance (7a - 8c) associated with the peripheral device may be operated by said peripheral device in the absence of instruction from the central control unit. <IMAGE></p> |
