Introduction: The automobile industry is taking intelligence as the spear, winning the future, intelligent driving auxiliary configuration is an important part of it, the leading car companies in various fields are conducting relevant research, and from the perspective of the auto show, a large part of them have chosen the lidar route, emerging Xiaopeng P5, AION LX Plus, WM M7, Zhiji L7, Jihu Alpha S Huawei HI edition and many other lidar models, bringing "the year of the blowout of the lidar model". As a representative car company of pure visual routes, how does Tesla perform? Today we will talk about the development of lidar and pure vision routes.
Xiaopeng P5 is the world's first lidar mass production car, and has been listed, its intelligent development route, that is, lidar and visual perception are integrated; and Tesla as a pure visual route spokesperson, its Model 3 is also one of the current intelligent car technology in the forefront of the model. Now, many people are hesitant to face the Xiaopeng P5 and Tesla Model 3, so let's compare them to see what the differences between the two cars are.
Xiaopeng P5 lidar design, to achieve urban NGP
First, let's look at the lidar design of the Xiaopeng P5. Xiaopeng P5 lidar is placed on both sides of the front bumper, one on the left and one on the left, and the front face is designed harmoniously, which enhances the sense of technology of the model. Many models like to put lidar on the roof, because the probability of the roof being hit is smaller and safer, which also brings a problem, that is, it will affect the aesthetics and increase the wind resistance. Moreover, placing it on the front end of the car has another advantage over placing it on the roof, according to the fan radiation range of lidar, lidar placed in front of the car can also increase the coverage of perception.
What is the lidar used in the Xiaopeng P5? According to the understanding, its lidar comes from DJI, using multi-lens reciprocating scanning, the blind area is less than 0.5m, the detection distance is 150m, reaching the centimeter-level high-precision ranging, with the ability to perceive the three-dimensional information of the environment, which is also one of the most important advantages of the lidar scheme compared to pure vision.
What is the difference between the Xiaopeng P5 equipped with dual lidar and the intelligent driver assistance configuration? It is the key to Xiaopeng P5 upgrading XPIRAT 3.5 intelligent assisted driving system, after filling the gap in perception, Xiaopeng P5 can not only achieve high-speed intelligent navigation assistance driving system (high-speed NGP), intelligent follow-up, lane change, overtaking on the highway, intelligent entry and exit ramp, through tunnels, and also support urban NGP, traffic light intersection intelligent traffic, urban intersection intelligent overtaking, roundabout road traffic, Y-type intersection assistance and so on.
Previously, intelligent driving on urban roads was a dream for smart cars, and now "dreams shine into reality", after upgrading XPILOT 3.5, driving Xiaopeng P5, even in the face of complex urban road conditions, you can easily move forward, saving us a lot of energy.
Tesla Model 3 pure visual design, aimed at urban roads
Tesla is on the opposite side of lidar, and founder Musk has diss lidar in public, saying: "People are driving vehicles with eyes and biological neural networks, so it makes sense that cameras and silicon neural networks are the only way to achieve a universal solution for autonomous driving." So, what is Tesla's pure visual solution? Without radar, without a high-precision map, it takes a completely different road, with cameras and algorithms for road environment recognition, vehicle driving judgment.
According to Musk's idea, now "the processing power of visual computing has been much faster than radar, enhanced visual operation is a better choice than tangled radar", we can find that this route has extremely high requirements for algorithms, because it cannot directly obtain three-dimensional information like radar, so it is necessary for the algorithm to undertake this part of the operation.
Tesla Model 3 equipped with FSD system, what kind of driving experience will it bring? At present, the foreign FSD system has been updated to Beta V10.5 version. The FSD system can achieve a large number of intelligent auxiliary driving functions to achieve urban intelligent auxiliary driving, but according to observation, it still has some problems, such as the collection of the road environment relies on cameras, but the camera used by Tesla is relatively backward, which will affect the data collection of the front section of the algorithm. In addition, the current FSD test effect shows that it will appear snake-shaped driving on streets with wide lane lines, and the stability needs to be increased, and it may misjudge illegal traffic social vehicles, and in streets with particularly large traffic, vehicles will repeatedly judge and hesitate. In this case, the FSD system still needs more testing and does not have the conditions to be officially pushed to China.
Static evaluation, both cars recommended star rating
From my personal point of view, with lidar to achieve 3D modeling, the perception of the road environment by smart cars will be greatly increased, which is more reliable and labor-saving than using algorithms for calculations, so in terms of intelligent assisted driving, I may be more inclined to Xiaopeng P5. However, the choice of a car is not actually determined by a single attribute, and it is necessary to refer to many factors for decision-making, so in other aspects, the two cars can also be passed.
For example, in terms of appearance, the appearance design of Tesla Model3 has been evaluated mostly by praise, low-lying design, and Porsche's highly similar shape, elegant curvature, so that it looks like there is a sense of high-end, not lack of science and technology, but also full of sports explosiveness. Xiaopeng P5 is another type, Tesla is a car for drivers, and Xiaopeng P5 is a car for families, it has sharp straight lines, sharp corners, but also rounded surfaces, soft curves, elegant streamlines, not too prominent futuristic sense of technology, but also not mediocre, the front face X lights, tail through the tail lights, the same cool.
For example, in terms of space, the interior design of tesla Model 3 is also more biased towards the driver, including the center console that is more biased towards the driver, and the rear row where space is much complained about. The back row is often where the family rides, but the Tesla Model 3 has only 2 fingers of effective head space and two punches of effective leg space.
In contrast, the interior space design of Xiaopeng P5 is more transparent, and the center console adopts a symmetrical design, which is more friendly to the main driver, co-driver and rear seat, and is more suitable for home use. In terms of space, Xiaopeng P5 has an effective space for the back seat of 3 fingers, an effective space for the back leg of nearly 3 punches, and the family can get a better driving experience when sitting in the back row. But its most attractive thing is the further development of the space in the car, which can not only sit, but also lie down. The front seat is reclined, and the inflatable mattress is laid out, which can be transformed into a bed, on this basis, Xiaopeng P5 also arranges a car projector and other configurations, so that users can also watch movies and ball games in the car.
Based on the intelligent assisted driving configuration, the comparison of appearance and space, give the Xiaopeng P5 and Tesla Model 3 a star, how many stars can they take away? I am willing to give Xiaopeng P54 stars and a half, the remaining half of the stars wait until next year's urban NGP can be used and then send it (in fact, soon into 2022), and Tesla Model3, I am willing to give it 4 stars, the deducted half of the star will also have to wait for the city intelligent assisted driving to officially go online, and the remaining half of the star is lost in the simple design of the interior and the tight rear space.
