Development and Start of Mass Production of Compact and Lightweight Relay Box for High-class SUV

摘要

The amount of electrical equipment installed in an engine compartment has increased as features of recent vehicles become more diversified. In addition, engine compartment space has been reduced to provide more cabin space and better visibility as a measure to protect pedestrians. Accordingly a relay box1) installed in an engine compartment must be downsized and made highly functional, such as by incorporating ECU2) functions. Measures for heat release are also required.
