Hardware-In-the-Loop-Simulation HILS System for Testing Eletcric Power Steering Systems

摘要

The present invention relates to a motor-driven power steering apparatus test HILS (Hardware-In-the-Loop-Simulation) system.; May be under the vehicle environment, self-test to perform the test exposure to the dangerous situation, and the complexity and difficult to measure in the test procedure by the non-linear element of the vehicle dynamics, it is impossible to repeat the test.; The present invention is an electric power steering apparatus of the mechanical parts of the endurance test, Ishihara oil (ECU) in the control logic test, the steering to be subjected to the test for the sensor signal test such as wheel, steering column, a rack, a motor, ECU, the steering comprising a sensor to a portion the remaining part which the dynamic behavior of the tie rod, steering linkage, chassis and tires of parts hardware, and vehicle using the very fast (Digital Signal Processor) DSP or operation speed computer, the reaction force required for the hardware unit to real-time simulation It is configured to implement a software portion calculated by using the actuator. Able to test the performance evaluation of the electric power steering device formed by the actual vehicle test by the present invention in a laboratory, thereby significantly can reduce the speed and its lifting expense of product development time.
