The invention discloses an active
brake pedal travel simulator and a control method of the active
brake pedal travel simulator. The active
brake pedal travel simulator and the control method of the active brake pedal travel simulator and aim to solve the problem that in the prior art, requirement for hydraulic adjusting unit performance is too high, and utilization of existing components is insufficient. The active brake pedal travel simulator comprises an inner circulation nut with teeth, a screw rod ejector rod, a driving gear, a motor, a second
piston, a first
piston, a simulator cylinder body, a spacing board, a
limit switch and a rear cover, wherein the rear cover and the simulator cylinder body are arranged on the left side and the right side of the spacing board, the inner circulation nut with the teeth is arranged on the rear cover and the spacing board through two thrust bearings, the left end of the screw rod ejector rod is arranged inside a hole of the inner circulation nut with the teeth and is in rolling connected with the inner circulation nut with the teeth, the right end of the screw rod ejector rod is inserted into the second
piston inside the simulator body, the first piston is arranged on the right side of the piston, the motor is arranged on the lower portion of the simulator cylinder body, the motor and the driving gear are fixedly connected, a
motor control device is arranged on the motor, the
limit switch is arranged on the rear cover, and the
limit switch and the
motor control device are in wire connection. The invention further provides the control method of the active brake pedal travel simulator.
