DESIGNS OF INPUT AND OUTPUT DRIVER CIRCUITS FOR 16-BIT ELECTRONIC CONTROL UNIT (ECU) AND DEVELOPMENT OF CONTROL STRATEGY FOR ECU USING THESE I/O DRIVER CIRCUITS

The rapid prototype based method for design process of control strategy of electronic control unit for input and output driver circuit for 16-bit Electronic Control Unit (ECU). This method saves time and cost for making of an electronic control unit board and uses the electronic control unit board having a type of microcontroller in which we can flash code many times for generation of control strategy. Based on the given circuit, development of control strategy for electronic control unit is done in microcontroller’s supported IDE. Then, test and verify the developed code with the use of given input and output driver circuits for electronic control unit on test bench with virtual engine environment setup or in an actual vehicle. The whole process is associated with development of Engine Management System. In this paper the input and output driver circuit design is given for further development of control code for four wheeler vehicles. Using this technique the validation process of electronic control unit board is done on test bench setup or in actual vehicle.
