BRAKE-BY-WIRE CONTROL METHOD AND CONTROL SYSTEM FOR UNMANNED VEHICLES

A brake-by-wire control method for unmanned 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.
