Continuous Improvements Analysis in Energy Efficiency of Steering Power Systems to Light Vehicles

Abstract:

This study analyses the energy consumption of a vehicle steering system and evaluates potential earnings in using more efficient systems. The energy consumption of the steering system to provide assistance can be until 3% of the vehicle total energy consumption. The technology evolution of the steering system provides a significant reduction in energy consumption. Three types of steering systems were evaluated: Hydraulic Power System, Electro-Hydraulic Power System and Electrical Power System, respectively, considering the consumption and the energy efficiency of their components. Some evaluations of the energy consumed by system components were performed using data from the available sources in the literature and other evaluations were performed via experimental tests on a bench test. A comparative study was set to determine the differences between steering systems regarding the energy consumption and energy efficiency. Consumption analysis of steering system were extended to evaluate the impact in the final vehicle consumption. The Electrical Power System can increase the efficiency in fuel use during operation in the vehicle.
