A double-motor driving type electronic hydraulic brake system capable of actively simulating pedal feeling comprises a brake pedal, a fluid storage tank used for storing brake fluid, a pedal displacement sensor, a pedal force sensor, a hydraulic force sensor, an electronic control unit, an electromagnetic valve, an electronic stability control module, a brake master cylinder and a secondary master cylinder. An electric control linear movement module comprises a rotating motor and a speed reduction and moment increasing mechanism which converts the rotating movement of the motor into linear movement to achieve the active control over system hydraulic brake force and pedal force. The pedal force of a driver can be fully used for reducing pressure. While the active control over the pedal force is achieved, a pedal force simulator of a complex structure is omitted, the feeling of a brake pedal is guaranteed, and the accurate automobile brake condition is fed back to the driver. The active control over the hydraulic force is achieved, and the brake requirement for automatic driving vehicles is met; maximum braking energy recovery is achieved, control is precise, and the response speed is high; double-loop braking is achieved, failure protection is considered thoroughly, and the safety is good.
