Senta ● Masamichi Ishii ● Honda, Hidei Miyamon announced March 4, the new Honda Legend, which was released the next day, has become a hot topic because it has the world's first level 3 autonomous driving system.Level 3 is limited to traffic congestion on highway (including urban high -speed), so recent level 2 is enough?Even if you think about cost performance, it is a nod, but it is a nod, but the original attitude of challenging the world's first challenge, taking the risk of failing to fail, is the original Honda -likeness.When I felt it, I actually tried a test drive, and it was confirmed that the combination of limited level 3 and high level 2 was quite useful.

Current status of "SIP Automatic Driving" challenging with All Japan [Masamichi Ishii's car technology 2nd]

The system "automatically driving" a system is above Level 3

"About the level of automatic driving" by the Ministry of Land, Infrastructure, Transport and Tourism (from the Ministry of Land, Infrastructure, Transport and Tourism announced by the Ministry of Land, Infrastructure, Transport and Tourism)

　The level of autonomous driving was originally proposed by SAE (Society of Automotive Engineers) in the United States, which was also adopted in Japan. There were level 0 to level 5, and it was on the market to level 2. As shown in the separate table, the driver's subject is the driver up to level 2, and although it is a part of level 3, it is a major difference in the system, that is, the car side is responsible for the operation. In recent years, level 2 has also been greatly advanced, and some are close to level 3, but it is not easy to move from level 2 to level 3. Therefore, no matter how high level 2 cars were, it was called "driving support". However, in Japan, on April 1, 2020, the Road Transportation Law under the jurisdiction of the National Police Agency and the Road Transport Vehicle Law under the Ministry of Land, Infrastructure, Transport and Tourism were amended, and the environment in which level 3 is approved in the world. In the past, in Japan, the technology of automakers was advanced, but the adverse effects of vertical administration and too cautious, practical use often lagged to the world. Such aspects have been seen in collision damage reduction brakes, but in the current automatic driving technology, there has been a reversal phenomenon that the cars implemented after almost a year after the legislation are developed first. (Consideration about this is another opportunity). That's why the legend was the world's first level 3.

In autonomous driving, the system performs "cognition", "judgment", and "operation" instead of drivers.

A sensor necessary for autonomous driving equipped by Honda New Legend.In addition to conventional cameras and radar sensors, there is a rider sensor that recognizes the distance and shape to the object.

　For driving a car, drivers perform "cognition", "judgment", and "operation" in a continuous cycle. This is replaced by the car side system in autonomous driving. The driver is mainly visible to "cognition", with "judgment" in the brain, "operation" with handle with hand, accelerator or brake with feet. Autonomous driving is a sensor such as a camera, a millimeter wave radar, and a rider (LIDAR), and the "judgment" is a control unit (computer) based on the information obtained from the sensor, but the "operation" is digitized. Use the handle, accelerator, and brake (drive by wire). Of these, "operation" is already more advanced as humans or beyond. In ACC (Adaptive Cruise Control), the system performs the accelerator and brake with the foot instead of the system, but it is "Hands Off" that the system performs the "foot -off", the Nissan Skyline and BMW under limited conditions. At the level 3 of the "Honda Sensing Elite" equipped by the new legend, the "Eye off" is realized in the sense that the driver is partially released from the driver's forward surveillance obligation. However, Legend's level 3 is extremely limited. Only the traffic congestion driving function named "Traffic Jam Pilot" is automatic driving level 3, but it can only be used in highway and urban highway (such as the Metropolitan Expressway Metropolitan Land Line). And only in traffic jams. If it is 30km/h or less, it will be activated, and once it works, it will continue up to 50km/h.

Related technologies developed before Honda reached Automatic Driving Level 3.Automatic driving level 3 is established after the accumulation of these technologies.

What I learned by trying a new legend with an autonomous driving level 3

A self -driving level 3 function works during traffic jams on the highway, and "Izoff" is allowed to take an eye on it from the front.

　The test drive was performed in the evening, mainly in the Metropolitan Expressway, when crowded. It is a disgusting mind drive that goes into a traffic jam while checking traffic information, but it is a disgusting mind drive to enter into situations that are usually avoided as much as possible. Although it was flowing smoothly for a while on the Metropolitan Expressway, I tried to support in -lane operation with a hand -off function that was not in the conventional Honda Sensing. If you can grasp the lane and your own position properly, the hands -off of OK even if you release your hand from the steering, BMW is also used in the case of traffic jams, and the skyline is also possible at high speed, so it is a high -speed run -off that in the legend. I can do it. Honda's LKAS (lane keep assist system) has good feeling even for reasonable compact cars such as fit, but the legend with expensive sensors and dynamic maps (high -precision 3D map) goes further up. It can be relaxed and driven in relatively fast traffic, such as the Metropolitan Expressway, Gulf Line, and Tokyo outer Ring Expressway (C3). However, as I felt on the Skyline, I sometimes be confused about what to do in the hand -to -hand area away from the steering. It is a driver -based operation support, and you have to be ready to return to operation, so you can't play your hands. I think it's surprisingly heavy when you leave your hand from the steering. It is easy to leave the left arm in the center armrest, but the right arm is a little distance if you try to leave your fulcrum on the door handle, and you will get tired after a long time. This is a challenge of all cars equipped with advanced level 2 or higher, including where the feet should be placed when using ACC, and it will be necessary to fundamentally reconsider the design of cockpit. 。 There is also a function that supports lane changes as a hands -off. The function of automatically changing lanes by turn signal operation is not unusual, but it is rare for the system to judge the surrounding situation and support the lane change and overtake including the turn signal operation. This time, in a situation where the exit traffic congestion extended to the main line even though it was flowing smoothly, we experienced a wise control that automatically changed the lane from left to right to avoid it. There was a speed difference between the right and left lanes, but I was greatly impressed that I found a safe gap and properly changed and accelerated. Finally, we entered the traffic jam on the 6th Misato Line. The traffic jam pilot worked when it was less than 30km/h. Until then, it was in a "foot -off" and "hands -off" state, but "Eye off" is possible. However, the legendary Honda Sensing Elite is only allowed to remove the gaze from the front and see the center display. During normal driving, images such as TVs and DVDs are not shown, but it is possible when the auto jam pilot runs, so watching it is tolerated as a so -called second task. The rule is that you don't have to look forward, but you have to be able to return to driving immediately. In other words, it is out of the question to sleep, but depending on the interpretation, it may be allowed to operate a smartphone. Is it out to eat lunch boxes that are likely to be scattered if you don't put them carefully? There are no detailed rules and ambiguous, but the legend is focused on a very limited second task. According to the rules, the car will automatically suspend an emergency if the system does not respond even after 10 seconds after requesting the driver to operate. The legend first tells the driver by displaying meters, HUDs, tightening a seat belt, etc. If it is necessary to stop the hazard and horn if it is necessary, it is impossible to do so if it is impossible. Stop on the driving lane.

Impressions and problems that experienced autonomous driving level 3

　In a total of about two and a half hours, I was in a total of 20 minutes, but just relaxing there was much reduced and it seemed comfortable. However, it is necessary to be prepared to return to operation immediately when the traffic jam pilot is lifted. If you are too loose, you may be worried that your attention will be distracted immediately after the start of operation. It is also a problem that the driver is overconfident and relying too much as the system becomes convenient. Even if there is no malice, it will tend to be too psychological. In fact, understanding such a thing means that it is quite limited but to level 3. Don't hurry too much, but if you don't take a step, nothing will start. The history of autonomous driving has just started.
