Method of making module for automotive electrical systems

摘要

An electrical system for an automobile comprises a plurality of slave modules connected to one or more respective loads and/or sensors, a power bus connecting the slave modules to a power supply and a signal bus connecting the slave modules to a control module operable to remotely control the switching of power supplied to the loads by the slave modules and/or the sampling of signals from the sensors wherein at least one of the slave modules and/or the control means comprises a thick film printed circuit formed on a metal substrate. The system simplifies the wiring loom of a vehicle and provides circuits which are resistant to vibration and electrical interference.
