The invention provides a no-offset prediction control method and system of a brake-by-wire system, a vehicle and a medium, and relates to the technical field of brake-by-wire. The method comprises the following steps: acquiring disturbance information of a target brake-by-wire system at a first moment, position information and rotating speed information of a motor in the target brake-by-wire system at the first moment, and target position information of the motor; using an explicit model prediction controller to calculate the target torque of the motor according to the disturbance information, the target position information of the motor, and the position information and rotating speed information of the motor at the first moment; and according to the target torque of the motor, performing pressure control on a main cylinder in the target brake-by-wire system. According to the mode, the pressure control precision and robustness are improved.
