Abstract :
The development and design of new energy-saving system of electro-hydraulic power steering (EHPS) has extensive application prospect. EHPS system is analyzed by using energy flow method, system model based on energy cost is established, and relevant compute simulation is performed. Tests are carried out on the hardware-in-the-loop (HIL) bench. The results showed that system voltage supply, PWM duty cycle, pump capability, tie rod force, and steering ratio are different degree impact on energy cost. This study will provide a theoretical reference and practice guidance for developing and designing energy-saving EHPS system.
