Development and Application Road Testbench on Vehicle Hydraulic Power Steering System

Abstract:

In order to study operation characteristic of the hydraulic power steering (HPS) system, a data gathering system, based on the testbench, was designed to test HPS system operating on-road. By using various kinds of sensors, such as hydraulic pressure, fluid flow rate, steering torque, corner angle, angular velocity, vehicle speed, gyro sensors and so on, convert steering wheel angle, angular velocity, torque and other operation parameters into analog voltage signals, which provided to real-time data acquisition, storage and analysis. 11 physical quantities can be tested simultaneously, including steering system and operation parameters of vehicles. Different angular velocity of steering wheel speed and "S" shape road were tested on different vehicle speeds, and the result shows that the tests are in accordance with theoretical analysis, which proves the data gathering system's credibility.
