The invention discloses an emergency stop control system and method and a pavement machine.The emergency stop control system comprises a low-voltage power supply system, a vehicle control unit (VCU), a motor controller, a motor and an emergency stop switch, and the low-voltage power supply system is connected with the VCU and the motor controller; the emergency stop switch is arranged on a circuit connecting the low-voltage power supply system with the vehicle control unit VCU and the motor controller, and the vehicle control unit VCU is used for generating a braking instruction under the condition that an emergency stop signal of the emergency stop switch is not detected within first preset time when a preset fault occurs. The braking instruction is sent to the motor controller; and the motor controller is used for applying a braking torque to the motor connected with the motor controller according to the braking instruction so as to control the speed reduction of the corresponding motor, so that the power-off task of the vehicle body is completed. According to the method, when a driver cannot make emergency stop operation in time, automatic speed reduction control over the vehicle body is achieved, and riding safety is guaranteed to a certain degree.
