The invention relates to an emergency braking and auxiliary gear shifting device and method for a pilotless automobile. The device comprises a power source, an electromagnetic relay, an emergency stop switch, a programmable logic controller, a stepping motor, a first proximity switch, a second proximity switch and a pilotless automobile controller. The power supply is respectively connected in parallel with positive and negative ends of the programmable logic controller and the stepping motor, one end of the electromagnetic relay is connected with the power supply, the other end of the electromagnetic relay is connected with the emergency stop switch and then is connected to the programmable logic controller, two ends of the unmanned vehicle controller are respectively connected with the electromagnetic relay and the programmable logic controller, and the stepping motor is connected with the brake pedal through a connecting piece. The first proximity switch directly faces a brake start position of a brake pedal, the second proximity switch directly faces a brake stop position of the brake pedal, and the stepping motor, the first proximity switch and the second proximity switch are all in communication connection with a programmable logic controller. Compared with the prior art, the method is not influenced by an automobile bottom layer drive-by-wire protocol and an unmanned driving control system, and has high portability.
