Abstract:
An electronic control unit comprising:a casing including a heat dissipation plate; a driving circuit substrate having driving elements mounted thereon for supplying electric power in a controlled manner to actuators connected to the electronic control unit, the driving circuit substrate being mounted on the heat dissipation plate; a control circuit substrate having control elements mounted thereon for controlling operation of the driving elements based on signals fed from sensors connected to the electronic control unit, the control circuit substrate being contained in the casing apart from the driving circuit substrate with a separating space; a connector for electrically connecting the actuators and sensors to the electronic control unit, the connector being mounted on and electrically connected to the control circuit substrate, at least a part of the connector being disposed in the separating space; and a flexible printed-circuit-sheet for electrically connecting the driving circuit substrate and the control circuit substrate, one end of the flexible printed-circuit-sheet connected to the control circuit substrate being positioned in a vicinity of the connector.
