The paper introduces a hardware-in-the-loop (HIL) driving simulator with the implementation of a look-ahead cruise control considering forward road information. The vehicle dynamics are simulated real-time in the high fidelity heavy duty vehicle simulation environment TruckSim, while the proposed look-ahead control algorithm also runs real-time on dSPACE MicroAutoBox II. The latter functions as a vehicle electronic control unit (ECU) and is used for rapid control prototyping (RCP), hence the proposed look-ahead driver assistance system can be tested and tuned in a real-time HIL vehicle simulator before installing dSPACE MicroAutoBox II in a real vehicle.

The paper introduces a hardware-in-the-loop (HIL) vehicle simulator built for testing and tuning a look-ahead cruise control algorithm considering forward road conditions. The aim of the vehicle simulator, apart from conducting real-time demonstrations and tests, is to create a HIL architecture which can be directly applied to a real heavy-duty vehicle formerly represented in TruckSim. By this means, several otherwise expensive road tests can be implemented with the simulator to increase the efficiency and reliability of the developed look-ahead control method.

Vehicle Dynamic Model

The development of a real-time driving simulator involves highly complex integrated and interdependent subsystems that require a large amount of computational time. When advanced hardware is unavailable for economic reasons, achieving real-time simulation is challenging, and thus delays are inevitable. Moreover, computational delays in the response of driving simulator subsystems reduce the fidelity of the simulation. In this paper, we propose a technique to decrease computational delays in a driving simulator. We used approximation techniques, sensitivity analysis, decomposition, and sampling techniques to develop a surrogate-based vehicle dynamic model (SBVDM). This global surrogate model can be used in place of the conventional vehicle dynamic model to reduce the computational burden while maintaining an acceptable accuracy. Our results showed that the surrogate model can significantly reduce computing costs compared to the computationally expensive conventional model. In addition, the response time of the SBVDM is nearly five times faster than the original simulation codes. Also, as a method to reduce hardware cost, the SBVDM was used and the results showed that most of the responses were accurate and acceptable in relation to longitudinal and lateral dynamics. Based on the results, the authors suggested that the proposed framework could be useful for developing low-cost vehicle simulation systems that require fast computational output.

The authors have researched on the communication protocols and the diagnostic modes used by the second generation of On-Board-Diagnosis (OBD-II) system and put forward a project scheme of automotive fault real-time alarming system based on OBD-II system. The Total Control Unit (TCU) of the alarming system, the signal conversion module between TCU and OBD-II system, the preliminary expert system of automotive fault diagnosis, LCD display system and phonic broadcast system have been developed. Test results on sample machines prove that the alarming system can successfully acquires data stream & trouble codes from automotive electronic control unit, so the expert system can comprehensively analyze potential fault causes and provide the driver with solutions. The fault causes and solutions can be displayed on LCD and converted into voice by text-to-speech module. The wide spread of the alarming system would effectively reduce the costs of vehicle operation and maintenance and greatly improve the vehicle road safety.

The advancement in embedded systems, which includes the mass deployment of internet-connected electronics, allows the concept of Internet of Things (IoT), to become a reality. This paper discusses one example of how an internet-connected embedded system is utilized in an automotive system. An Electronic Control Unit (ECU), which functions as a control unit in a fuel injection system, are equipped with Wi-Fi capability and installed on 110cc motorcycle. The ECU is connected to multiple sensors that is used by the ECU as part of control system, as well as giving raw data in real time to the server by using Wi-Fi as the communication medium. The server will accumulate data transmitted from ECU by using MQTT protocol, chosen due to its minimal data profile. The data can be visualized through web portal, or opened by any other web-enabled devices. The data collected may also be used later for any other purposes, such as On-Board Diagnostics (OBD) system, etc.
