Through the use of onboard computers (ECU) with "cooperative control", it has become possible to achieve unusually high levels of control over a car. With ECUs communicating in parallel to achieve this cooperative control, the design of the onboard network has become highly important. Gateway Unit, as a part of the onboard network, has responsibility for relaying communications through focusing on complex cooperative control.
Properties of Sumitomo Wiring System, Ltd. Gateway Unit
Our gateway for vehicles has been developed and mass produced for more than 10 years, and we achieved to reduce thickness and weight of the product at the highest level. Having over 50 types of gateway-installed cars, we support the in-vehicle network infrastructure of recent years.
We have various channels such as the CAN (Controller Area Network) installed in many cars, and control the relay between the channels. It is manufactured to have the best component and software structure so any relays will not be leaked or communications to be delayed, since it relays the communications that control the whole vehicle.
"Door Lock, Keyless Entry, Head Lamp, Room Lamp, and others are a part of the electrical unit which controls the functions that are active inside the car. You can customize the controlling system depending on the model of car."
It is possible to offer products (such as Junction BOX and PKE function integration for customer needs) based on various system configurations, which adapt to the structure changes based upon function.* The PKE function system integration ECU can start the engine and lock/unlock the door while the remote control is inside a pocket, bag, etc.
