The integrated development system for an electronic control system 2000-05-0092

In this paper, a new kind of integrated development system for vehicle electronic control system is introduced. This system consists of pure simulation, real-time hardware-in-the-loop simulation, and road test in a real vehicle with the same computer. The system can verify the software and hardware of a vehicle controller with the same software environment. The control algorithms of controller can be transferred from pure simulation in a PC computer to target microcontroller with little change. This is a rapid prototype system for developing an electronic control system for both hardware and software. With a dual RAM, the target CPU, such as Intel 80C196 microcomputer, can be integrated into the system to form also pure simulation, real-time hardware-in-the-loop simulation and road-test system, respectively, in the same computer. Taking advantage of PC hardware and software, the developing period from pure model simulation to a final sample controller is shortened by this system. With the Visual Basic computer language, the simulation program is of modularization and encapsulation. The pure simulation, hardware simulation and road test can be done in the same Visual Basic project so that their results can be compared and analyzed immediately. The problems in the controller for hardware and software can be modified immediately. An optimal control algorithm for the vehicle controller can be found easily. All of work keeps continuous and one step provides technology support for next step. Finally, an example of ABS simulation and test is presented to illustrate this system efficiency and effectiveness.
