MIT researchers point out problems that self-driving cars currently have

In 2012 Google is fully automated driving, no need for driversMovie running in the town with a visually impaired man on "Self Driving Car"Although I made it public,Massachusetts Institute of TechnologyIssued by "Technology Review"Warns that all self-driving cars, including Google's, have problems to solve.

Ford FusionThe 2013 sedan model of "Adaptive cruise control(ACC) "and"Lane keeping systemTwo automatic functions are installed, that is, Adaptive Cruise Control is a function to measure the distance to the front car using radar and to control the accelerator and brake to keep safe distance, the lane keeping system is the camera mounted on the rearview mirror Use it to check whether the car is running off the lane, check the drive, vibrate the steering wheel to inform the driver, or return the handle slowly if it seems to be out of the lane.

For these two functions, in order to maintain safety and to give priority to the driver's will, the function to stop when it comes to limited circumstances is installed. For example, if Adaptive Cruise Control runs at a speed less than 12 mph (about 19.3 km / h), or if a car ahead travels faster than the speed set initially, it will stop working .

Also, even if the automobile overflows the lane, the lane keeping system will ignore it if you steal it steadily and you can automatically ignore it when you are traveling in a place where the lane is old and color is balanced It has become specification to cut. According to Technology Review, despite these restrictions, adaptive cruise control and lane keeping systems operate wonderfully and wisely and are likely to be as reliable as they are used.

Lincoln · MKSDetects the space that can safely park and the driver performs parallel parking etc. almost perfectly by just adjusting the brakeActive Park AssistIt is equipped with the function. According to Technology Review who tried Lincoln · MKS, when the car automatically started backing up while parking, I felt terror when I saw the tire rotate at a great speed, but I saw that it was accurately parked It seems that she was very surprised. However, there seemed to be problems, too, it was good up to the place where I parked along the lane accurately, but it was difficult to get off because I was too close to the car parked next door.

The three automatic functions mentioned so far, "Adaptive Cruise Control", "Lane Keeping System", "Active Park Assist" are impressive at first glance that they are convenient and safe, but what is the problem Is it?

According to the Technology Review, from the problem of "the distance to the car parked next to" that occurred while testing Lincoln / MKS, "Can you effectively adapt human behavior and machine capabilities? The question that "? Certainly, Active Park Assisted in Lincoln / MKS, even if it can park exactly along the lane, even considering that the car parked next to the lane is parking beyond the lane I was not able to park.

Cognitive scienceBe a personDon NormanHe said "Design of the future product"Pointed out potential problems self-driving cars have. For example, with regard to adaptive cruise control, self-driving cars are automatically accelerated because there is no signal in the exit roadway from the expressway to the ordinary road, or the self-driving car is automatically accelerated while changing the lane while traveling at a constant speed It seems that there seems to be a problem such that it decelerates suddenly at the moment of arriving at the back of the car. Mr. Don Norman notes that fully automatic operation will be more secure but problems will arise if only some of the functions are automated during the transition period of the automatic driving function.

Also, Technology Review notes that the self-driving car movie released by Google last year will not be relied upon. The car used in the movie was traveling at exactly the same route as I went through at the time of shooting and it was not the first road that I went through.


There is no system that can anticipate how humans react and act against unexpected unexpected events still. When running in the state left to automatic operation, when a situation in which the driver has to drive suddenly happens, can the driver who enjoyed the auto drive by the dream suddenly cut off the steering wheel and can avoid the crisis If you say, the question remains.

Also,MIT Age LabAccording to Brian Raimer who is a researcher and researcher of the driver's behavior, if it depends too much on automatic driving, the driver's driving ability may fall. The driver's ability to leave half of the 20 km to automatic driving, the driver who starts driving after remaining 10 km, and the driver who has driven to the 10 km point of the 20 km without depending on the automatic operation is the same even for the same person That is not it.

Furthermore, Mr. Laimer said "How do you connect the human brain and automatic driving technology?The problem of being forgotten is said. Mr. Norman also wrote in his book that "automatic driving must consider how well the driver feels during driving" must be considered.

Mr. Reimer set up on the dashboard at MIT's laboratory to which he belongsHeart rate· The resistance of the current flowing through the skin decreases with the moisture of the skinGalvanic skin reaction·Eye movementsWe are studying to measure the "mental workload and attention" of the driver from the sensor which checks the driver, and in the near future, the machine mounted in the self-driving car can communicate more with the driver, the driver I understand more what kind of body / mental situation is.
