Briefly talk about the upgrade of VeSCoM and the use experience of 7800km.

Directory? Foreword (see post)? Let's talk about this first. VeSCoM? How do you feel after upgrading VeSCoM? ? 7800 kilometers. What's your new understanding of CT5? ? In the drawing area, people with tight traffic avoid it? end

1.？ All the following contents about VeSCoM are obtained by myself through online search, personal guess and field experience. As a liberal arts student, I can't guarantee the correctness of the following conclusions about the structure of in-vehicle software, nor do I represent all personal feelings. Welcome to discuss, but please don't argue. ? 2.？ Please use civilized language, talk rationally about cars and respect others; ? 3.？ The picture is uploaded to the last chapter, and there is nothing else. You can quit after reading the fourth chapter.

I believe that some riders in the jar have upgraded the whole vehicle VeSCoM, and many riders are watching or looking for opportunities to do this upgrade. During the 11th Five-Year Plan period, I went to the 4S store. After the upgrade, I began to wonder what this VeSCoM is. By using "an unknown foreign search engine", I found a small amount of information related to the word VeSCoM, as shown in the attached figure.

From it, we can see that this is an advertisement for a position related to "super cruise system VeSCoM", which can be regarded as "Vehicle? Software? Configuration? The abbreviation of "management", I haven't been to this phrase since my CET-6 is less than 500. Can you simply understand it as a vehicle software control system, combined with the world? B architecture, I think it can be understood simply and rudely: global? Under the framework of B, the whole vehicle system consists of the whole VeSCoM and each module VeSCoM (such as the VeSCoM of the super cruise system in the above advertisement), and a brand-new electronic architecture of CT5 vehicle is established, which is different from the traditional fuel vehicle.

This is the upgrade interface that I sneaked into the workshop when I was waiting for boredom. As you can see, many modules of the whole vehicle are involved, even the restraint system (seat belt) is involved. I want to say a few more words here. Many riders think that programs such as K20, K7 1 are included in this VeSCoM upgrade package. Some riders mentioned that the master should brush K7 1 separately. I understand that the master has to search the system for K7 1 and brush it again. As a subroutine in a package, it should be possible in theory. Of course, this operation has no effect on the whole vehicle at all. The above is just my inference. Rational discussion is welcome.

From this point of view, my previous idea that VeSCoM is a trademark of a manufacturer or the name of a suite seems completely wrong. The reason why I saw this name for the first time in all the upgrades of CT5, I guess it is because this is the first major upgrade of CT5' s in-vehicle system. Compared with the upgrade at the beginning of this year (only engine, body stability module, etc. ), which is obviously a set of system updates related to VeSCoM, a CT5 vehicle module, released by GM on the basis of continuing to study vehicles and summarizing opinions from all parties, and also reflects the OTA capability of CT5 vehicles. However, compared with the OTA update of electric vehicles, the OTA of CT5 must be returned to the factory, and as can be seen from the above figure, the upgrade program can only be obtained by professionals logging in the internal website, and the owner cannot upgrade it by himself, which reflects the complexity of the whole vehicle architecture of fuel vehicles and the lag of traditional car companies in the field of electronic architecture.

1.？ Engine power output:? The horsepower is getting bigger. . . . . . It's impossible. An engine adopts the upper and lower cylinder technology, which shows that this engine is not intended for you to explore its potential. However, after this upgrade, the throttle adjustment has become more sensitive than before. Now in comfort mode, the power output can be more in line with expectations, and the initial stage of sports mode will become more restless. After the upgrade, the comfort mode under urban road conditions can basically meet the power demand of starting scenes, and the degree of throttle following has been significantly improved in the common speed limit range in urban areas. ? 2.？ Transmission response:? I still hold this view. There are too many gears in 10AT, so it is impossible to exercise in my life. However, I have to say that the upshift speed of the gearbox is 30% higher than the original. In comfort mode, the most common upshifts of 1-2, 2-3 and 3-4 are almost without hesitation, but 1-2 occasionally has setbacks, which may be a side effect caused by speeding up. In pick mode, the switching speed is greatly improved (note that it is greatly improved). As shown in a HUD short video shot by Cheyou @ gooseberry and Lilac at the altar, the picking speed increases immediately after downshifting, and then falls back after upshifting, which greatly improves the following degree. However, in sports mode, the logic of deeply stepping on the accelerator to downshift is not perfect, and the process of thinking about life still exists. ? 3.？ ESE acoustic wave compensation system and ANC active noise reduction: What many riders have not mentioned is that ESE has almost no sense of existence in comfort mode. I accelerated quickly in comfort mode many times within two days after the upgrade, and the engine noise was greatly reduced. Therefore, I personally think that ESE reduces the intervention intensity in comfort mode, and at the same time enhances the active noise reduction function of ANC in comfort mode, and jointly realizes the hedging of engine noise. ? 4.？ Other details:? The ECO mode is very frequently involved. When running smoothly at any rotation speed in the range of 50-80, almost 90% will trigger the double-cylinder super-economic mode, which brings out a defect. Originally, my car has never encountered the problem of engine mount resonance in ECO mode, but after this upgrade, there is a 20% chance that it will resonate at 1400r R, which is a cliche problem of engine electronic mount. I wonder if there is a solution in the future.

This time, I won't talk about it in categories like the last one, but briefly talk about some points that I feel deeply (only for top models). ? 1.？ The chassis has excellent texture. At present, the consensus of all walks of life is that CT5 suspension is biased, but in the long-term use process, it can be felt that CT5 suspension is mainly sports, and at the same time, it is very good to isolate the bad information of the road surface. The suspension of CT5 chassis on continuous shallow and thin pits really fascinates me. The stability shown on the highway is reassuring, and the strong support shown on the mountain road is exciting. ? 2.？ The direction is extremely accurate and the steering ratio is just right. When driving on a mountain road, you can turn around and turn in the direction of 3/4 laps, so that you can handle most bends with two hands at three or nine o'clock, which greatly improves the safety and convenience; In daily driving, the steering wheel movement perfectly matches the expected body response without unnecessary correction. But the disadvantage is that the direction is obviously affected by the road surface and crosswind. The potholes on the road will be directly transmitted to the steering wheel, and the driver needs to hold the steering wheel at all times in the case of strong crosswind (he personally experienced a windy day of magnitude 7 on the elevated Daxing Airport Expressway). ? 3.？ The brakes are sensitive and powerful enough. When driving at a speed of 30-40kph, I got distracted and misread the traffic lights. By the time I knew it, the front of the car had reached the stop line, so I immediately braked and trampled to death. After parking, watch the rear wheel stop firmly in front of the parking line to avoid triggering a red light to take pictures, saving a huge sum of money. ? 4.？ The fuel consumption is not good. For one thing, I don't like LSY anymore. Is it fuel efficient? It is really economical when running at high speed and steady state, and the fuel consumption below 9 really breaks the traditional cognition of American cars. So I ask again, does it save fuel? No, CT5 traffic jam has nothing to do with fuel economy. The average fuel consumption within 500km of the dashboard is 13L, and the average fuel consumption calculated by WeChat Travel Assistant is12.8l. In contrast, another first-generation Angkewei top-mounted, LTG nose, 2.0T+6AT at home shows that the average fuel consumption after long-term use is 1 1+L, which is basically unchanged. In addition, as a 5-meter car, CT5' s fuel tank size is at the passing line level, which leads to my cruising range of 400km after filling it up every time, which is unacceptable for a fuel-efficient car.
