Car electronics are a form of technologies to electronically control the operation of car mechanisms. Cars today use more electronics in a broader range of components than ever before: engines, transmissions, suspensions, steering, brakes, and air conditioners. With cars becoming more and more electronic, we need further weight and size reductions in electronic and electrical components, which have sharply increased, along with more efficient assembly of these products. Sumitomo Wiring Systems is also aggressively developing modularized products with fewer parts by consolidating or combining them through functional integration.

The center module contains the switch panels and color monitors for air conditioners and audio systems and is installed in the center of the instrument panel. It plays a central role in sophisticated in-vehicle information systems and provides a comfortable operational environment. |
The heat control panel has a security alarm indicator basides air conditioner control and display functions, thus providing a user-friendly operating enviroment. Besides, the built-in microcomputer performs heat control and communication. |
Small relay modules are made by concentrating and reducing the size of the relays that output control signals that operate different systems. We have achieved smaller and lighter relay boxes by developing high-performance and low-heat-generation small relay devices and highly-efficient heat dissipation technologies. |
