From human measurement to computer measurement, the Intelligent Evaluation of Driving can be more reliable.
Hey! It’s going to hit!
If you often pay attention to the short video of evaluating the intelligent driving ability of the car, I believe you will not be unfamiliar with this beginning. From the beginning of the video, I have been working hard to catch the audience’s eye all the time. Screaming, cheering, ups and downs of the "plot" throughout the video.
The video is breathtaking and full of traffic, but it gives people a feeling — — I said everything, as if I didn’t say anything. An autopilot engineer also lamented helplessly that most of the intelligent driving tests on the market now lack professionalism and are too subjective and one-sided. "Just watch it as an entertainment program."
A few years ago, in order to test AEB, people and cars made of cardboard were used as obstacles from the media. Not only was the professionalism questioned by the audience, but even the car companies finally went to court.
And high-order intelligent driving is far more difficult than AEB test. Not only fairness and justice are needed, but also stronger professionalism is needed. It is more difficult, more uncertain and more complicated. How to judge as objectively as possible is also the key.
At the same time, the location of the test is also particularly important. Nowadays, high-level intelligent driving is moving towards the "no map era", and many car companies have started the slogan of "all the countries can open". However, many tests are still clustered in first-tier cities such as Beijing, Shanghai and Shenzhen, and what’s more, they are directly tested by lines arranged by car companies. In this scenario, whether the car companies have made "software special adjustments" or "fake maps" is probably unknown, including the media evaluated.
Needless to say, this test result not only can’t truly reflect the intelligent driving ability of a car, but also can’t prove that a car can have similar performance in other parts of the country.
This also makes many users feel "confused". "After reading so many evaluations, it seems that I can’t tell who is good and who is bad." A friend who is interested in intelligent driving commented on today’s intelligent driving evaluation.
However, there is an intelligent driving test video in a video column recently, which is somewhat different.
2 million devices "get on the bus", and the professionalism is further improved.
In July this year, Baidu’s smart car test video column "Intelligent Evaluation of Driving" released two new videos. Different from the usual intelligent driving test, this test directly uses the R&D-level auxiliary driving truth equipment of automobile enterprises. The total price of this equipment is close to 2 million yuan, including three mechanical lidar, optical fiber integrated inertial navigation system, time synchronization equipment, horizon smart camera, several cameras, acquisition industrial computer and industrial computer display.
This set of equipment can record a lot of information. For example, test the vehicle’s body posture, acceleration, position with other traffic participants, and the distance from the lane lines on both sides in the lane. This information is of great significance to objectively analyze the intelligent driving ability of a car.
Using this set of equipment, the evaluation has entered a more professional and objective era of "machine measurement" from the stage of "human measurement". The output of "anthropometry" is mostly subjective, but it lacks strict unified scales and standards, and it is difficult to give quantitative results and analyze specific problems. The "machine test" can accurately record the assisted driving performance of the vehicle. For example, the acceleration value given by inertial navigation system can be used to accurately measure the braking ease or braking urgency of a car; Whether a car is centered in the lane or whether there is a phenomenon of "painting dragons", you can use the images taken by the camera to record the distance between the car and the lane lines on both sides.
Looking through the previous videos of "Intelligent Evaluation of Driving", we can find that they have used this set of truth-assisted driving equipment to test high-level intelligent driving since the program was launched in September 2023. This is also the first time in the industry that the media has adopted this equipment for testing, which is the first in the industry.
Intelligent driving Baoding test? Closer to the user’s real car scene
The latest two videos have chosen the stage of intelligent driving test in Baoding, Hebei. As a second-tier city, Baoding will not be given priority by the "special adjustment" of car companies, and the road conditions in Baoding are highly complex, and there are many other traffic participants such as electric vehicles, which makes the test difficult. This ensures that the column can test the ultimate capacity of a car under the condition of "no picture" and no special adjustment, and the reference value is higher for users.
This test restores the user’s car scene as much as possible. For example, the test time is selected at the congested road section in the morning and evening rush hours, and it includes scenes such as intersections and unprotected left turns that occur frequently in the city; At the same time, in addition to the working condition of urban roads, the test also added scenes such as high-speed roads and rural roads to ensure that more scenes that users care about are covered, and practical reference content is provided for users.
At the same time, the test not only covers unprotected left turn, morning and evening rush hour congested roads, expressways and country roads, but also tests special tests with Baoding characteristics and high difficulty, such as "true and false right turn lanes", "tidal left turn intersection" and "Liudaokou".
Choose a car to buy a car, watch intelligent evaluation, and search for "intelligent evaluation of driving" on Baidu APP.
If you have been paying attention to the column "Intelligent Evaluation of Driving", you will know that these two programs are only their "basic operations".
As early as 2022, Baidu’s professional active safety test caused widespread concern. The test not only uses professional equipment and venues, but also covers extreme working conditions such as fog, rainy day, night and backlight. These tests have aroused heated discussions among the audience and manufacturers, and even promoted the algorithm upgrade of the main engine factory, improving the shortcomings of active safety of smart cars. In 2023, Baidu Youjia launched a strategic cooperation with the National Automobile Quality Inspection and Testing Center (Tongzhou, Beijing) to jointly pay attention to the field of automobile intelligence and jointly formulate and publish a scientific and perfect evaluation system, which undoubtedly made the intelligent evaluation of Youjia more credible.
With the rapid development of new energy vehicles, intelligence has become the focus of the "second half competition" of new energy vehicles. The intelligence level of a car will affect the decision-making of users and the key battlefield of R&D and announcement of car companies. To this end, Baidu Youjia, as a professional automobile media, launched the first large-scale automobile intelligent evaluation program "Intelligent Evaluation of Youjia" in the whole network.
This column will focus on the intelligent configuration and intelligent safety ability of popular cars on the market for data testing, and score them in multiple dimensions through an authoritative evaluation system. The evaluation content covers the intelligent high-frequency functions of automobiles, such as active safety capability, intelligent assisted driving capability, intelligent parking, intelligent cockpit, etc. Various evaluation scenarios are developed, and an industry-specific three-dimensional evaluation system is built by combining closed simulation test and open road measurement, so as to test and score intelligent automobiles, aiming at providing practical intelligent automobile test conclusions for car consumers.
In addition to the city-level high-speed NOA intelligent driving test, this column will bring more practical scenarios for users in the future.
Intelligent test content, deeply cultivate the field of intelligent evaluation of automobiles, and bring more valuable automobile evaluation columns to users. select
Buy a car, watch the intelligent evaluation, search for "Intelligent Evaluation of Driving" on Baidu APP, and you can see the latest videos and previous programs of this column in the search card.
This kind of professional, fair and reliable test is the most lacking in this traffic age. I also hope that there will be more automobile test columns to present more valuable content to users from a more professional and objective perspective.
