“…Due to these advantages, there are a number of commercially available products specialized in HIL simulations of ECUs; e.g., products from AVL, dSPACE, and ETAS. There are numerous HIL systems to test various functions of the ECU; e.g., HIL of Anti-lock Brake Systems (ABS) [6,7], HIL of Electronic Power Steering (EPS) [8], HIL for testing of velocity/distance controller for driver safety system [9], HIL system of throttle body for testing of engine throttle controller [10], and HIL system to test diesel hybrid electric vehicle [11].…”

Safety and performance have always been important factors in automotive testing. These factors are highly dependent on the tires and suspensions, which should be simulated and tested throughout the development process. During development, Hardware-In-the-Loop (HIL) simulations may be used so that testings and tunings can be done earlier in the process. In this paper, designs and configurations of a newly developed tire-suspension-steering HIL are shown. An actual wheel assembly with suspension and steering components can be installed for testing with dynamic models of the rest of the car. The slip angle of the tire can be imposed in the test rig while actual tire forces can be measured and used in the dynamic model. Comparisons of HIL simulations and real experiments using the skidpad test and the step steering test are given using Formula SAE race cars. It was found that the HIL simulation results are more accurate compared to non-HIL simulations.

“…Steering torque is defined as the torque a driver applies on the steering column while turning the steering wheel. When an appropriate assistant torque by an assist motor is applied in the same direction as the driver's steering direction, the amount of steering torque required for steering can be significantly reduced [3][4][5][6]. In addition, adjustment of the characteristics of the assistant torque allows the driver to experience various steering feels [7].…”

-ISO 26262 is an international standard for the functional safety of electric and electronic systems in vehicles, and this standard has become a major issue in the automotive industry. In this paper, a functional safety compliant electronic control unit (ECU) for an electric power steering (EPS) system and a demonstration purposed EPS system are developed, and a software and hardware structure for a safety critical system is presented. EPS is the most recently introduced power steering technology for vehicles, and it can improve driver's convenience and fuel efficiency. In conformity with the design process specified in ISO 26262, the Automotive Safety Integrity Level (ASIL) of an EPS system is evaluated, and hardware and software are designed based on an asymmetric dual processing unit architecture and an external watchdog. The developed EPS system effectively demonstrates the fault detection and diagnostic functions of a functional safety compliant ECU as well as the basic EPS functions.

Development of HILS system for the electric motor using coupling analysis with rigid body system and hydraulic system analysis with rigid body system and hydraulic system is presented in this paper. From the fuel consumption improvement point of view, the electric drive system is applied to the construction machinery for improving fuel efficiency and reducing pollution emissions. In the development of the electric drive system, it is important to evaluate the dynamic characteristics of the electric motor and control system, then HILS provides an approach for efficient development. This HILS system can act the actual load on the motor by calculating the coupling system equations of motion with the rigid body system and the hydraulic system in real-time. The real-time simulation was conducted by newly developed simulation model that the rigid bodies were actuated by the linear hydraulic actuator. A test rig was developed following this concept, in which the load computed by real-time simulation of the actual digging operation on the hydraulic excavator was exerted to the electric motor. The test results with developed testing system were compared with the simulation results using the simulation model with the electric motor. It is demonstrated that the HILS system of the electric motor can realize the actual digging operation of the hydraulic excavator. 1．緒言 AbstractA new concept of HILS (Hardware-In-the-Loop Simulation) system for an electric motor using the real-time coupling
