Electronic control unit for controlling multiple external devices mounted in vehicle, has power control circuit that transforms voltage from power source device and supplies transformed voltage electronic components mounted on substrates

摘要

The control unit has substrates that are accommodated in housing, to which motor (11), gear (12), door locking unit (13) and safety device (14) are connected. The power supplied from power source (15) is received by secondary substrate. The primary substrates are parallel to secondary substrate. The secondary substrate is arranged such that the substrate main surface is located adjacent to inner surfaces of housing. The voltage from power source is transformed by power control circuit and is supplied to electronic components mounted on substrates.
