Baidu car, two of the latest developments officially announced:
Two lidars are mounted on the car to achieve 180-degree field of view detection coverage at the front end.
In terms of route selection, Jidu revealed that the mass production car will adopt a pure visual route and a multi-sensor fusion two-algorithm redundancy scheme including lidar.
And the two sets of schemes are independent of each other and complement each other - the "adult" set degree, do not choose.
At the same time, he said that the epidemic in Shanghai has no impact on the jidu concept car and the later mass production.
Two recent developments?
The first is the lidar on the car, the front cover.
Dr. Wang Weibao, head of Jidu Automobile Intelligent Driving, revealed that the software integration engineering prototype SIMUCar 2.0 has been equipped with 2 lidars and opened the test of multi-sensor solutions.
Compared with the pure visual route of the SIMUCar 1.0 stage, after the addition of lidar, the blind spots processed by the visual scheme can be supplemented with redundancy, such as driving scenes at night.
In terms of detection effect, Jidu released a night test video:
Left LiDAR point cloud detection effect:
Right LiDAR point cloud detection effect:
Here are the 2-piece lidar fusion detection effect:
In terms of driving scene processing power at night, such as unprotected left turn in low-light conditions at night:
Narrow Road Meeting Car:
With the dual lidar blessing, the performance is more relaxed.
It is reported that the two AT128 semi-solid-state lidars used in Jidu are from Hesai Technology.
In terms of capabilities, a single lidar has a 120-degree field of view coverage capability, which can achieve a super long-range measurement capability of 200 meters at 10% reflectivity, and the farthest ground line can reach 70 meters, and the number of point clouds, the point frequency exceeds 1.53 million points per second.
Set degree means that 2 lidars can achieve horizontal 180 degrees of field of view coverage, compared with a single lidar 120 degrees of field of view, the range is wider, the detection is more comprehensive and accurate.
For example, in driving scenes such as "ghost probes" and left and right obstructions, the ability to recognize pedestrians or obstacles across the left and right is stronger.
At the same time, in the field of view area of 60 degrees in front of the vehicle, the dual lidar can be doubled and overlapped, and the point cloud data on the target is more, and the recognition accuracy is higher.
The second is the intelligent driving route.
Does the use of lidar mean that Setdull abandons the pure visual route of the SIMUCar 1.0 stage?
No, the set of degree revealed that SIMUCar 2.0 stage, will use pure vision and multi-sensor fusion two sets of solutions to test at the same time, and in the future mass production, to achieve program redundancy.
And unlike traditional fusion schemes, the two systems are independent, backing up and complementing each other.
As for which system is dominant after mass production, and how the two systems work and make decisions, the concentration is not disclosed.
In addition, the intelligent driving program of Jidu is also different:
The position of the lidar.
Judging from the poster of the latest side details of the concept car released by Jidu, there is a bulge on the left and right sides of the front cabin cover, which is most likely the mounting position of the lidar.
I have to say that this shape has a bit of the taste of ancient hidden headlights, like this:
In contrast, most of the current models equipped with lidar have placed lidar above their foreheads in order to detect a larger range.
There are also schemes such as Xiaopeng P5, which are placed in the front side of the headlight area, which is relatively beautiful.
The scheme and design of Jidu is the first time in the industry.
Are there any other new developments?
Another development comes from the JET intelligent architecture developed by Jidu.
Wang Weibao said that the SIMUCar 2.0 testing phase has been opened, and the phase goal is to prepare for mass production.
At this stage, the underlying architecture of SIMUCar has been upgraded from the original Geely SEA haohan architecture to a high-level autonomous driving intelligent architecture JET (JIDU Evolving Technology) developed by Jidu.
It is reported that the Jidu JET architecture is based on the Baidu Apollo platform and the Geely SEA architecture, including the electrical and electronic architecture EEA and the vehicle operating system SOA, which can achieve L4 level automatic driving and software and hardware decoupling.
According to the plan, by the end of this year, the relevant domain controllers and sensors of JIDU SIMUCar, as well as some basic autonomous driving capabilities, such as ADAS functions, parking, intelligent interaction, etc., can reach mass production.
In other words, the final preparations for the launch of Jidu's 2023 mass production vehicles will be completed by the end of this year.
In addition, Jidu also revealed more product plans:
Jidu has started the research and development and pre-research of follow-up models, and its second mass production car is expected to be released at the Guangzhou Auto Show at the end of this year.
The above is all the content of the latest progress of this jidu car manufacturing.
one more thing
Finally, there is a matter of great concern:
Under the epidemic situation in Shanghai, several depots have stopped production, or issued early warnings of production suspension, and the debut of the Jidu concept car has been postponed, so will its first mass production car be affected and postponed?
The response in terms of set size is:
The company has set up a special procurement team, the Jidu concept car, as well as the first mass production car delivered in 2023, will not be affected by the epidemic.
Also, Jidu's second car was also announced: the Guangzhou Auto Show, just at the end of this year.
