“…The Autobox, developed by the German company dSPACE, is used for rapid prototyping and hardware testing in a loop simulation based on MATLAB/Simulink software [15]. The main functions of the Autobox can be subdivided into four steps: firstly, the drive signals which are sent from the powertrain control unit to the actuator model is gathered by using the I/O board.…”

Abstract:Fuel economy efficiency is one of the most important parameters for vehicle powertrains, which is of particular interest for heavy-duty powertrain calibration. Conventionally, this work relies heavily on road tests, which cost more and may lead to long duration product development cycles. The paper proposes a novel hardware-in-loop modeling and calibration method to work it out. A dSPACE hardware-based test bench was successfully established and validated, which is valuable for a more efficient and easier shift schedule in calibration. Meanwhile, a real-time dynamic powertrain model, including a diesel engine, torque converter, gear box and driver model was built. Typical driving cycles that both velocity and slope information were constructed for different road conditions. A basic economic shift schedule was initially calculated and then optimal calibrated by the test bench. The results show that there is an optimal relationship between an economic shift schedule and speed regulation. By matching the best economic shift schedule regulation to different road conditions; the fuel economy of vehicles can be improved. In a smooth driving cycle; when the powertrain applies a larger speed regulation such as 12% and the corresponding shift schedule; the fuel consumption is smaller and is reduced by 13%. In a complex driving cycle, when the powertrain applies a smaller speed regulation such as 5% along with the corresponding shift schedule; the fuel consumption is smaller and is reduced by 5%. The method thus can provide guidance for economic calibration experiments of off-road heavy-duty vehicles. OPEN ACCESSEnergies 2015, 8 9879

“…This result is transferred to the column, where the force that influences the steering system F rack is produced. The driver forms the closed circuit that receives the repulsive force during steering (Ludger, 1996;Hanselmann, 1993). The hardware component of the HILS system consists of the steering wheel, steering column, rack, and pinion.…”

“…The use of hardware-in-the-loop-simulation (HILS) systems to develop EPS systems allows the testing of simulations and gives credibility to using a hardware system (Hanselmann, 1993). The HILS system in this paper consists of mechanical hardware, which extends from the steering wheel to the steering rack bar, and software that simulates the lateral force caused by the tires .…”

In this paper, a hardware-in-the-loop simulation (HILS) system was developed before the development of an electric power steering (EPS) system in a vehicle. This study was focused on the establishment of the HILS system. Driving conditions are simulated with the HILS system. The actual steering input parameters are confirmed on the monitor while driving the HILS system. The steering forces observed in the simulation with the developed HILS system are similar to those in real vehicle tests. The developed HILS system can be applied in the development of various types of EPS systems.
