Application of CAN bus with dSPACE simulator usage

Abstract

In recent years we can see the increasing of electronic control systems in cars. The reason of this increasing is to ensure better safety, comfort, requirements of users and to bear up against the competitive pressure etc., last but not least the pressure of single governments on all the time reducing of consumption sources and the tendency to lower the emitting of emissions to the atmosphere too. These require to implement new systems to the car. The growing of control systems has the influence on quantity of interconnecting wires, which brings the problems (failure rate, unreliability of connection, disturbance, energy losses, etc.). The right coordination of individual control units have to be ensured e.g. the co-operation of engine, ABS/ASR and automatic gearbox. These systems come through different tests for the ensuring of correct functions. For these purposes the serial communication protocol (Controller Area Network - CAN) by BOSCH company was created. The protocol is designed especially for using in the cars. CAN is used for connection of different device types (drivers, sensors, actuators etc.) through the serial data bus. This protocol is used in different industrial applications too. The reason is above all the lower price, easy access point, reliability, high data rate and easy extensibility.
