The invention discloses an active simulating type electronic hydraulic braking system for pedal feeling. The system comprises a brake pedal, a liquid storing tank, a pedal feeling simulating tank, a piston, a cylinder body, a returning spring for providing the pedal feeling to a driver, an electronic control unit which is used for receiving a sensor signal, calculating and sending a control instruction and connected to each sensor and a solenoid valve through conductors, an electric linear driving module which is in direct contact with a man braking cylinder and used for driving the piston of the main braking cylinder to linearly move according to the signal from the sensor, the main braking cylinder which is connected with a brake wheel cylinder through a brake pipeline and used for generating hydraulic pressure, and a solenoid valve for opening and closing hydraulic pipelines connected with the main braking cylinder and the pedal feeling simulating cylinder and used for actively simulating the pedal feeling and ensuring the braking effect in case of failure. According to the system, the pedal feeling can be actively simulated, so that the braking intention of a driver can be correctly reflected, the braking requirement for automatically driving a vehicle can be met, the brake energy can be recovered to the maximum, the control is accurate, and the response is fast.
