Recently, Baidu's Jidu Automobile, its first car robot concept car cabin cover double radar design has aroused heated discussion among the big guys in the car circle.
First of all, Li wanted to speak out, saying that it could not pass the collision regulations, and the performance was no different from that of a single radar; in this regard, He Xiaopeng publicly contradicted it, and recognized the dual radar scheme of the Jidu car, and the performance of the two lidars was far better than one.
A few days ago, the founder of WM Motor also mixed in, WM Motor Shen Hui said, about the lidar I see this:
1, whether it is the number or location, or depends on the actual use environment. The WM M7 has a horizontal viewing angle coverage of 330° through the layout of the overhead 1 + 2 on both sides, which can take care of the cornerstone case in most cases. In this way, perhaps 3 is the optimal solution for the current level of perception and safety balance, too few blind spots, too much meaningless.
2, the simple number of lidar and location dispute is of little significance, short-term cost, long-term technology, perhaps when the perception hardware is good enough, pure vision is the end.
According to previous reports, Jidu Automobile officially also said that the "dual lidar" design scheme is very innovative, the location of the lidar is not only distinctive, the appearance is very plus, and the configuration of its dual lidar also shows safety advantages.
However, Li Xiang, the founder of Ideal Car, disagreed with the design of the cabin dual radar. Pedestrian collision regulations can't pass this pass, and there is no difference in performance, and even the performance of the single overhead will be better.
In this regard, He Xiaopeng sang the opposite: two lidars are definitely far better than one in terms of performance, and the difference can be seen in the future in the urban NGP and robustness. In fact, the hardware configuration simply represents a possibility of potential, ultimately a balance of safety, cost, scenario and capability, still the barrel effect rather than sprint logic.
What do you think is better about the speeches of the bigwigs in the automotive industry?
