Abstract
The electronic control unit controls operation of actuators connected thereto based on sensor signals fed thereto and processed therein. The unit includes a control circuit substrate carrying control elements such as a microcomputer and a driving circuit substrate carrying driving elements such as power transistors. The driving circuit substrate handling power and the control circuit substrate handling only signals are separately positioned in a metal casing with a separating space therebetween to suppress heat transfer from the driving circuit substrate to the control circuit substrate. A connector electrically connecting the unit to outside sensors and actuators is positioned in the separating space to utilize the separating space also as a space for containing the connector.
