摘 要：The structure design and pressure control of electro-hydraulic braking system (EHB) is essential for electric vehicles,which is critical to the braking energy recovery and vehicle stability control.In this paper,the overall structure of the electro-hydraulic braking system is analyzed,and classification method according to how the braking pedal is decoupled with the braking pressure is proposed.Through the PID control method to achieve pressure following control,it lays the foundation for electric vehicle stability control.
