CAN(FD)/LIN Network Development Consulting Service

Overview
With the advent of the era of automotive intelligent networking, the in-vehicle network system not only needs to provide shared information channels, save wiring harnesses for the entire vehicle, reduce costs, but also be able to carry more functions. Core technologies such as intelligent driving, Internet of Vehicles, OTA, functional safety, and information security put forward higher requirements for in-vehicle network communication. At present, the mainstream vehicle network platform is a hybrid architecture of multi-segment and multi-bus types. The bus type involves CAN/LIN/CANFD/FlexRay/Ethernet. In the vehicle development process, whether it is multi-segment cooperative sleep and wake-up logic, multi-bus Types, routing design, multi-bus network time analysis, functional safety E2E requirements, information security SecOC requirements, or Ethernet-based SOA design, all put forward more requirements on the network design capabilities of OEMs. At the same time, the test technology of the new bus (CANFD/FlexRay/Ethernet) is an important means to ensure the quality of the vehicle model, and it is also an ability that the OEMs’ network platform needs to focus on.
Hirain has been involved in bus technology since 2002. Whether it is traditional CAN/LIN bus or new CANFD/FlexRay/Ethernet, we have in-depth technical research and project experience accumulation, and are committed to providing customers with high value-added services.
