Its usual test mainly considers the performance of adult passengers, children passengers, pedestrians and safety auxiliary equipment in the event of vehicle collision. The highest level is five-star safety, which is also the goal that all car companies are striving for.
First, assisted driving rating focuses on human perception.
In 2020, NCAP in Europe introduced a new project: Assisted Driving Rating (Assisted? Driving? Gradings), mainly testing the safety of new car driver assistance system in expressway. It is mainly divided into two aspects: assistance ability (based on the balance between driver participation and vehicle assistance) and safe backup.
Driver participation (driver? Engagement) and vehicle assistance (vehicle? Auxiliary), and secure backup (secure? Backup) add up to get the total score.
10 10 month 1, euro? NCAP announced the assisted driving rating of 10 cars. Che Jujun made the following arrangement according to official website's information:
The three cars with the highest scores are: Mercedes-Benz GLE, BMW 3 Series and Audi Q8, with scores above 80 points, which are excellent (very? Good) evaluation. Ford Sharp International (Ford? Wing tiger) 74 points, was rated as good.
Volkswagen Passat, Volvo V60, Nissan JUKE (corresponding to ESQ in Britain and finidi),? Tesla model? Four cars, including Class 3, scored between 59-7 1, all of which were rated as medium.
Renault Clio and Peugeot 2008 ranked in the last two places, with less than 55 points, and were rated as beginners.
The result is somewhat surprising. For example, the Volvo V60, which is famous for its safety, only got the average, while the Volkswagen model? 3 only got the average score, and the score was lower than V60, ranking third from the bottom.
You know, models? 3 just got the euro? NCAP rated "20 19 safest family car" and "20 19 safest electric car", and it was also the only car that won two awards. What, all of a sudden, you lost in the "assisted driving score"?
Second, the model? 3 Man-machine cooperation 0 points, different ideas?
Look at the evaluation rules first, and the model? The corresponding score is 3:
Auxiliary capacity includes "people" and "cars", that is, the participation of drivers and the assistance of vehicles.
The participation of drivers mainly depends on whether the information received by people is misleading, whether they can clearly perceive the driving state, whether they can give reasonable warnings and stop when people are not there, and whether people can receive the steering force of the system at any time and take over at any time.
Vehicle assistance mainly depends on whether the vehicle can recognize the speed limit sign and whether ACC is easy to use, especially whether LKA always stays in the middle of the lane when there is overtaking or overtaking.
In the "Driver Participation" module, what is the vehicle type? 3 lose a lot of points.
In the item of "consumer information", I only got 10 out of 25 points, because Tesla called its assisted driving system "Autopilot", in which "Auto" implies automatic driving, which is not allowed. On the other hand, Tesla said in the product manual that Autopilot has certain limitations. This contradictory statement has brought users trouble in understanding.
In the "system status" item, I got 16.5 out of 25 points. The reason for losing points is, model? Without the head-up display function, users can't see the driving information conveniently and directly.
In Driver Monitoring, I lost a lot of points, and only got 10 for 25 points. The reason is, models? Although there is an in-car camera, it does not monitor the driver. The system only relies on the steering wheel to monitor people-then it will condone the driver to cheat, such as stuffing an orange on the steering wheel, and then leaving the steering wheel with both hands to let Autopilot run by himself.
"Man-machine cooperation" is a model? 3 losing points is the most serious. Because when Autopilot is running, the driver's steering action is rejected. If the force is slightly greater, the driver assistance system will automatically quit.
This is also where Tesla is logically different from most OEMs. Most vehicles are allowed to manually turn to a new lane when the assisted driving is turned on, and then the system automatically captures the new lane line. Is this euros? The logic of NCAP's reasonable "man-machine cooperation" is that the system always provides steering force without violating people's will, and if there is conflict, people should be the main one.
Tesla believes that machine driving is safer than people. If people think that danger appears, they should take full responsibility, and the machine will quit turning. Its logic is: choose between machines and people, and machines are preferred.
Because of different ideas, models? In the "driver participation" item, only 36.5 points out of 65,438+000 points-the lowest score in the whole game. Although the following "vehicle assistance" got a high score of 9 1.7, according to the regulations, only the one with a low score was selected for the two modules to participate in the total score summary.
Because of the euro? NCAP believes that people and cars must reach a balance, and the good performance of either side can not replace the defects of the other side, nor can it represent the overall level of "auxiliary ability".
In the next "Vehicle Assist" module, what is the model? 3 overall performance is good.
In "speed assistance", what is the model? 3. Good performance on urban roads, and real-time speed limit can be identified by visual system; But at high speed, it can only rely on map data to provide fixed speed limit information.
Che Jujun has spit this out many times. See: "Tesla TSR is easy to make mistakes? Or suddenly slow down, customer service: 2020.36 software will be optimized? |? Get together and smell it.
Or, euros? NCAP still gives 16.7 a perfect score of 25, which is equivalent to 67 out of the perfect score 100. Therefore, Jujun is not sure about the rating scale of this institution. Where is it?
Next, models? 3 ushered in its own highlight moment.
In the ACC test, the obstacle cars in various scenes were successfully avoided. AEB only works when the car cuts in and the car in front cuts out.
In the LKA test, it can stay in the center of the lane at any speed, even in an S-shaped curve.
Therefore, it got full marks in the above two tests. Let's take a look at the Secure Backup module.
If the radar or camera is blocked, what is the model? 3 will call the police and will not be enabled. So I got a perfect score of 25 here.
If the driver does not respond to the warning, what is the model? 3' s system will automatically park the car in the driveway. Probably because the car can't park on the shoulder, I got 20 out of 25 points, which is a high score.
Interesting. AEB, euros? NCAP didn't describe it in detail, but mentioned it in the ACC above, and gave it a full score of 50 points. The illustration at the back draws five scenes: approaching a stationary car, approaching a slow-moving car, approaching a car that suddenly braked, inserting another car in front, and the front car suddenly dodged the car that approached the stationary car. Interestingly, the obstacles in these scenes are all "vehicles".
Che Jujun thought, what if this organization, like China Media, focuses on testing models? The reaction of pedestrians crossing the road may vary greatly. Relevant evaluation can be seen: "Baojun did an AEB test, and Tesla smashed the dummy and was defeated by a domestic car? focus
Finally, the euro? NCAP sums it up like this: Model? 3' s assisted driving system is outstanding in the "vehicle assistance" module, but it is a mess in the "driver participation" module, which can not balance the relationship between people and vehicles, which may lead to the driver's "excessive trust" in the system.
3. Volvo's evaluation is average, and no response is 0.
What is the performance and model of Volvo V60? One is different and the other is the same.
The difference is that it really respects people more. In the "driver participation" module, it got two full marks, namely "consumer information" and "man-machine cooperation".
Euro? NCAP review, Volvo's "pilot? Assist accurately describes the system functions, promotional materials and user manuals, and clearly points out the limitations of the system. At the same time, the steering force exerted by the driver and the lane keeping of the system can achieve a good balance, which is a model of man-machine cooperation.
The head-up display of V60 is also 18.3, with a full score of 25 points. Unfortunately, it doesn't have a built-in camera to monitor the driver's behavior, so it's similar to Model? The same score is only 10 out of 25 points.
Similarly, the score of V60 is 0, that is, "no response intervention" under the "safe backup" module.
If the driver does not respond to the system for a long time, the system will automatically exit the assisted driving state, but will allow the vehicle to run and stop in a free state without providing any control function.
Is the traffic sign recognition of V60 better than that of Model? 3 the score is higher. Because it combines the pre-implanted map information with the timely information captured by the camera when driving, it can reflect the fixed speed limit and the temporarily changed speed limit on the screen.
The ACC performance of V60 is good, and it will slow down properly before entering the corner, and it can avoid collision when encountering slow vehicles ahead. However, when the front is a completely stationary vehicle, it will be difficult to identify it. So I only got 20.9 out of 40 points, which is obviously a low score.
In an emergency (mainly referring to the side car cutting in and the front car cutting out), AEB of V60 can also help the car, but the help is limited, so it only scored 30.9 points out of 50 points.
This is actually the most unfair place for Volvo. The idea is that people still have to take the initiative under the L2 level of automatic assisted driving. If there's a car ahead, maybe there's Europe? The kind of dead angle measured by NCAP; But if there is a person in front, it is likely to be more sensitive.
A famous case is that in April this year, a Volvo XC60 drove into a dark tunnel in Foshan, and suddenly a pedestrian pushed a stroller through (Bian Xiao couldn't figure out how the millionth fairy-like walk happened). At this moment, XC60 slowed down instantly and turned left automatically, saving two families in one fell swoop.
This function is called "anti-collision assistance system" in Volvo, is it City? A sub-function of the security enhanced version, which is standard in the whole system and turned on by default. As long as the speed is above 60km/h and the marking line is visible, the system judges that the danger ahead is inevitable through the radar and camera at the front of the car, and will actively help the driver leave the dangerous lane.
At that time, many people were discussing whether XC60, a "tunnel shelter", was hit manually or systematically, or together.
Che Jujun dialed Volvo 400, and the answer was: In this case, if the driver has active operation behavior, the system will give priority to human operation and delay the activation of the "anti-collision system" because Volvo has always advocated human priority. Only when manual operation is not enough to avoid danger will the system start to assist steering and braking.
If the driver does not move all the time, the system will judge at the first time and avoid it urgently.
Therefore, Che Jujun tends to think that the XC60 owner had not had time to hit the direction at that time, and it should be the operation problem of the system. Because that action is faster than the average person, especially in dim light.
Ironically, euros? NCAP comment V60: it is not equipped with lane change assistance function.
It can be avoided in an emergency, but what is the use of lane change assistance? It can be seen that exam-oriented education is inevitable abroad. Besides Volvo's city? Safety has always been the standard of the whole department, which is one of the biggest differences between it and other brands.
Jeju tubercle
Through Tesla model? 3 and Volvo V60, can you see Europe? NCAP's tendency to assist driving test. It still has obvious "moral-oriented" thinking, and BBA ranks in the top three-it does not deny that they are safe, but it does not rule out that they know the rules better.
Volvo in northern Europe and Tesla in the United States, under the rules, are like two completely different kinds, with very distinct advantages and disadvantages.
Up to now, neither car company has responded. In fact, it is easy to get high marks: Tesla OTA shows the driver monitoring function, and then stops exaggerating publicity (this euro? The criticism of NCAP is correct); It is not difficult for Volvo to update its intervention without responding, such as double flashing and leaning on the side.
Sure, euros? This experiment of NCAP at least provides us with a basis and reference. If the shoes fit, put them on. Finally, Che Jujun wants to ask a question:
What if China's new forces move towards the euro? How many points will NCAP get?
