Controller Area Network for Automobile Application Using ASIC Based on PSoC and Analysing Through Vector CANoe

In the automotive industry, embedded control has grown from stand-alone systems to highly integrated and networked control systems. By networking electro-mechanical subsystems, it becomes possible to modularize functionalities and hardware, which facilitates reuse and adds capabilities. With the increasing number of distributed microcontrollers and intelligent peripherals used in today’s electronic systems, such as vehicle controls, networking protocols between the units have become extremely important. A wide range of these applications are using CAN (Controller Area Network) for network communication. The CAN bus was developed by BOSCH as a multi-master, message broadcast system that specifies a maximum signaling rate of 1M bit per second (bps). Unlike a traditional network such as USB or Ethernet, CAN does not send large blocks of data point-to-point from node A to node B under the supervision of a central bus master. In a CAN network many short messages like temperature or RPM are broadcast to the entire network, which allows for data consistency in every node of the system [1].
