Do not hold the steering wheel with your hands, do not use the foot to step on the throttle, brake, just use the "brain" to think about it, you can drive the car? That's right! After more than two years of trial and error, the research team led by Duan Feng, an associate professor of the School of Computer and Control Engineering at Nankai University, recently developed a “brain-controlled car†in cooperation with Great Wall Motor. It is understood that this achievement has achieved the connection between human brain driving and EEG signals and automobile systems for the first time in China. It is expected to change the driving mode of “hands and feetâ€, so that the dream of driving disabled people is no longer far away.
On July 15, Duan Feng research team conducted an experiment in Nankai University. A domestic SUV car went straight for about 20 meters, but there was no one in the driver's seat. The driver who was driving was sitting in the back seat. The experimenter wore an EEG signal acquisition device equipped with 16 collection points, and “issued orders†for a car equipped with a computer processing system, a vehicle-mounted electronic control unit, and the like through an EEG signal. Subsequently, the car accurately executed a series of prescribed instructions such as starting, straight forward, straight reverse, brake, door lock, unlock, etc. under the control of the human brain. Although the speed is not fast, all the moves are done in one go.
Specifically, the result is to capture the EEG signals generated by people's attention when they are focused by EEG equipment, and then use the EEG signal recognition system to analyze people's driving intentions and send control commands to the car. The purpose of the car to control. Some students also put forward on the spot: "Isn't the idea of ​​people opening and stopping in the brain, the car will be obedient? What happens if you think about something else on the way?" The experimenter explained that the driver should pay attention to it. When the force is generated, the EEG signal can be captured. Once an effective command is formed, the EEG signal recognition system analyzes the person's driving intention within 1 second and sends a control command to the car's electronic control platform to achieve the purpose of controlling the car by the human brain.
It can be said that the "brain-controlled car" subverts the traditional driving method used by the hands and feet, and can use the human brain to control the car and make it run at a low speed. However, the success of the “test drive†does not mean that you can drive on the road. It is not far from the actual production and use. According to Duan Feng, the brain control technology part of “brain control car†has been realized, but the electric system part of the car has yet to be further improved and transformed. The safety, intelligence and humanity of “brain control car†continue to increase. Space. In addition, the "brain-controlled car" is expected to be applied to the driving of physically disabled people in the future, but to truly drive on the road, it is also necessary to consider a series of issues in line with relevant national laws and regulations.
