Design of Compact ECU with Two-Layer Daughter Board Structure for Automotive High-Performance Computing
Soshi Shimomura, Masako Kato, Yutaka Uematsu · 2024
We proposed a new two-layer daughter board structure to balance both high performance and compact size in electrical control unit (ECU). The structure separates interface board and processor board for high-density implementation. We concluded the structure can realize cooling capacity of over 300 W, signal integrity of 6 Gbps, and the chassis size reduction of more than 20 %.
