PCB, PCB home automotive electronics is developing towards the direction of network and intelligence. Electronic control devices will provide stable and reliable low-cost network connection through CAN bus; motors, switches, sensors and lights will be connected through local interconnect network (Lin).
The solutions of world famous manufacturer Freescale include: can / LIN bus door control scheme based on 8-bit 908mcu, lamp control scheme, can / LIN network solution; 9s12c3216 bit Lin main controller controls steering wheel, lamp switch, air conditioner fan control (linslavehvacblower), air conditioner damper (linslavehvacdamperdoor) and instrument (linslavecluster), etc.
Automobile network technology
Automotive manufacturers and tier one suppliers face increasingly complex issues of safety, powertrain, chassis and body system harmonization. Emerging systems such as line control, collision avoidance, and assisted driving all need a network that can provide extremely high data rates in a predictable and reliable way. Most can support high data rate, however, its network standard is specially designed for connecting multimedia in vehicle. Can network can connect several ECUs, but the normal data rate is only 125k ~ lmbps
