Adopting vehicle-grade domain controller as the core brain of intelligent driving, self-developed vehicle-grade sensors as the environment sensing solution, and mature X-by-wire vehicles as the basic platform, Hirain is expected to provide customers with mature, safe, and reliable intelligent driving operation and maintenance systems. In particular, intelligent driving domain controller, intelligent camera, millimeter wave radar, intelligent gateway controller, Tbox, high precision map and positioning system are developed independently by Hirain.
In addition, based on many years of automotive electronics and intelligent driving system development experience, Hirain has defined the requirement of the braking system, steering system, drivingsystem, transmission system, parking system, lights, wipers, horn and communication protocols etc. for X-by-wire vehicles. The typical network 
framework of a X-by-wire vehicle is shown in Figure 4.
