Spent five hundred million to upgrade the new M7, no map city NCA first experience

Q Jie’s new M7 Big Five Seat is just an annual facelift model, but it is said that this facelift has invested 500 million yuan. It can be seen from the model name of the material spread this time that the "six-seat" and "zero-gravity seat" promoted by the old model was replaced by "Big Five" this time. It can be seen that this product has carefully learned the previous lessons, and the product definition direction has also been adjusted. In addition to the upgrades we think the facelift should have, the new car has also made a lot of targeted upgrades and changes. This article will introduce to you in detail.

[· 1 · Active and passive safety improvement]

Of the 500 million yuan invested in this renovation, 280 million of the cost is used to improve safety. In its cage body, the cost of high-strength thermoformed steel accounts for 24.4%, which is used in such places that are closely related to the safety of the passenger compartment. The high-strength steel and aluminum alloy account for 80.6% of the whole car. The skeleton is also added inside the threshold beam, the transverse and longitudinal beam structure is added, and the battery pack is designed with double anti-collision beams. In terms of active safety, the AEB active braking speed has been improved, and the lateral anti-collision, low-speed anti-collision, and ghost probe recognition have been optimized.

[· 2 · Design and configuration]

In terms of exterior design, the entire vehicle has not changed much, with changes in the front net and fog lamp areas, allowing people to distinguish it from the new M7. The most obvious features of the smart driving version are, of course, the camera modules on the fenders on both sides of the front and the roof.

The center console in the car has been replaced by a flocked package, which has improved the delicacy. The steering wheel adopts the same color design as the interior, which looks like the sense of fragmentation is reduced, but the material of the steering wheel has not changed significantly, the touch is still hard, and there is a lack of advanced sense. The car machine system has been upgraded to Hongmeng 3 system, which supports the circulation function of mobile maps and food APPs, as well as the automatic adjustment function of eye positioning in the rearview mirror position, and the Maglink multi-screen interaction in the rear row. You can use the ∞ in the second row through accessories to achieve linkage control with the car end. In response to the problem that the rear air conditioner of the old model cannot be heated, the new model has added an air conditioner box, which is specially responsible for the cooling and heating of the rear air conditioner. The trend of

[· 3 · Space gameplay]

In terms of space, the biggest change is the layout of the five-seat space. The seats of the whole car have been redesigned, and the foam material has become significantly thicker and softer, and the ride comfort has been significantly improved. The second row of elevation is significantly improved, the length of the seat cushion is longer, the leg support is in place, and the backrest can support electric adjustment. After the second row is reclined, it can form a through space with the luggage compartment, and the air mattress can form a more comfortable rest space in the car. The front seats can also be fully reclined and connected to the second row of seats (the headrest needs to be removed, and the main driver does not support the main driver to recline if he chooses the headrest).

In terms of chassis driving, in response to the previous chassis quality problems, the whole car has upgraded the FSD variable damping shock absorber, which alleviates the bumps in the driving, and reduces the excess rebound of the suspension when passing through the ditch. The texture of the chassis has been improved compared with the old model. In addition, the aluminum lower swing arm, aluminum and other mechanisms have also been reduced to a certain extent, which is helpful for improving the control. DATS has been upgraded to 2.0, the torque control logic has been optimized, and the four-wheel drive stability has been improved. Overall, the quality of the M7 chassis after the facelift has indeed been optimized. It is relatively hard compared to the chassis, and the integrity is relatively strong. However, due to the shape of the carriage and the suspension structure, the chassis frame control performance is slightly lower than

[· 4 · Get on the bus at NCA in the city without pictures]

In terms of urban NCA, we received news this time that the progress of urban NCA without high-precision maps has been accelerated, and by the end of this year, NCA without maps can be used nationwide, regardless of city.

This time, the author’s experience of NCA in Shanghai will be briefly reported to everyone.

First of all, let’s talk about the problem: the road conditions of the NCA without a picture are very complex, and it is still unable to deal with many special roads. For example, it is impossible to identify the signal light of a lane closure in the tunnel, the text prompt of the direct transit area and other text prompts, and it is impossible to identify the bus lane. In the face of temporary maintenance roads, it can accurately identify the stop, but it is impossible to take advantage of the detour. At present, it is still unable to identify the lower obstacles on the road surface. When encountering a suspected falling car on the road, it does not respond. At some intersections, there are cases of unprovoked pushing out. The traffic light countdown delay is slightly larger than before. The road information in the SR interface is now completely based on the recognition of the body perception system, including the signal light countdown information. The situation where the three-digit signal light could not be recognized before has not been optimized this time, and the SR interface signal light is still in two digits.

Therefore, in the face of some special road conditions, consumers must pay more attention and be ready to correct the wrong actions of the vehicle at any time. After all, the current regulations do not allow autonomous cars to be on the road. Under the premise of assisted driving, once any accident occurs, the responsible person is still the human driver.

In the route we experienced this time, in addition to the above problems, its intelligent driving experience is not much different from the high-definition map version, and it is significantly improved from the urban NCA version I experienced three months ago.

Progress is reflected in:

1. The efficiency of unprotected left turns is significantly improved. In all left-right turn road conditions, there is no parking and waiting situation, and the left-right turn is silkier than the previous version.

2 You can identify the left-turn waiting area. I don’t know if it is an accident. When you go straight ahead with a green light and turn left with a red light and there is a waiting area, there is no vehicle ahead, and the M7 smart driving version smoothly stops at the first place in the waiting area. The engineer explained that this is the waiting area information of this intersection included on the vehicle map. Because there is a certain angle in the waiting area, it is not the hardware perception of the vehicle.

3 The yellow light can be recognized. When the signal light is already clearly yellow, the end of the car has not made a deceleration action, but runs the yellow light at a constant speed. There are two possibilities for this result. First, the end of the car accurately calculates its own speed and the distance to the stop line, and combines the time when the yellow light appears to calculate whether it can pass the stop line before the red light. Another possibility is that there is a delay in the end of the car recognizing the signal light. When the end of the car senses the yellow light, the car has passed the stop line.

4. Continuous lane change processing at intersections is more silky, allowing for the one-time lane change operation of multiple consecutive lanes before traffic lights. The processing process is similar to that of human drivers, without the feeling of machine lane change.

[Write at the end]

After this test drive, the new M7 has five seats. It is the first time I have seen such a big change in an annual model. On the one hand, it shows that the old M7 does have some drawbacks, and the official has accepted the criticism of users and the media. This change is very targeted and sincere. On the other hand, combined with the pre-sale price of the new car 258,000 (30,000 yuan lower than the old entry price), it shows that Huawei and the world have high expectations for this M7, and the new car is bound to bear a heavier sales target. In this year’s highly competitive market, it is also urgent to grab its own, and the performance of the world is also an example for companies that cooperate with Huawei. Therefore, asking the world brand is the "of Huawei’s car end business. If you stand firm in the market, you can advance and retreat, and lose it, which will have a profound negative impact on future business development.

At present, there is an ideal L7 on the market, which is deeply rooted in the hearts of the people, harvesting a lot of orders every month, and there are 08 rookies, new design language, wearing advantageous resources, and the same technology-empowered cars should not be underestimated. The market competition will still become more intense. Who is the winner in the 200,000 yuan market, maybe by this time next year there will be a clear answer.
