The invention discloses a brake-by-wire control method for driverless vehicles comprises the following steps: step 1: collecting brake control information, obtaining initial positions of a release braking position value of the electric push rod and a maximum braking position value of the electric push rod, and recording them as d0 and d1; step 2: verifying and calibrating positions of the electric push rod when the vehicle brake is released and at maximum braking, recording a calibrated release braking position value of the electric push rod as D0, and a calibrated maximum braking position value of the electric push rod as D1; step 3: obtaining a current control signal of the vehicle, and obtaining a target value of the electric push rod for adjusting the vehicle braking; step 4: transmitting the target value of the electric push rod obtained in step 3 to a vehicle controller for controlling vehicle braking. By detecting the emergency stop switch signal and the automatic driving mode switch signal, this application can determine whether the vehicle is in a manual braking state or an automatic braking state, and perform different braking controls in different braking states. This in turn can improve braking control.
