In fact, I had completed the first guarantee of Shadow Leopard, and later received a notice that I could upgrade the software, but because the upgrade process took more than two hours, I did not go. This time I happened to go to the 4S store to deal with a problem with the fault light of the emission system - the reasons given by the dealership included that it might be a gas problem, or that the temperature was too low in the winter without a hot car to leave, and then suddenly reported a police - so it took more time to upgrade the vehicle software.
There are four software programs for this upgrade:
1. 21K6 Shadow Leopard GSM gear shift control mechanism upgraded;
2. 21K5 Shadow Leopard DCM front door control module upgrade;
3. 21K4 Shadow Leopard ESP electronic stability and parking control module upgrade;
4. 21K3 Shadow Leopard EMS/TCU software refreshed.
A pressure relief tube was then replaced, and after these upgrades were completed, the discharge system failure showed that it disappeared automatically.
To briefly explain, since we are the first batch of owners of Shadow Leopard J15, we have picked up the car in August, and the vehicle production should be earlier, so the corresponding software programs should be relatively early, so this upgrade has a very important significance.
Judging from the software features of this upgrade, it is mainly for the engine and transmission program to be adjusted. The first is to refresh the software of the engine management system EMS/TCU, that is to say, to change the engine program. It's just that the definition of this TCU is not very clear, the general TCU refers to the gearbox shift control unit, that is, the module that controls the work of the gearbox. However, another term is the "telematics control module", which is equivalent to a module that monitors a vehicle or engine.
Personally, I prefer the latter, as another upgrade mentions the GSM shift control mechanism upgrade, which should be the program that is really responsible for the transmission shift logic. But whether it is A TCU or GSM, the gearbox shift logic must be adjusted anyway, which is a good thing for early car owners.
Some upgrades of the ESP and parking control modules should mainly solve the problem that the autohold throttle will be flushed after starting. As for the upgrade of the front door control module, it is not clear, perhaps it is the induction and judgment logic upgrade of the key, because the automatic exit lock door in the previous use is relatively fast.
Without further ado, let's take a look at the changes in the driving experience after this upgrade .
First, when the Autohold starts, the moment you lightly press the accelerator to lift the automatic parking is smoother and softer. In the past, after stepping on the accelerator, the vehicle would indeed release the brakes, but it would rush a little, and the obvious sense of movement was a little uncomfortable. Now the action of the vehicle to lift the automatic parking is more natural, the power comes more slowly, and then it creeps slowly, which brings a better experience. In fact, the two differences can be experienced in D gear and R gear, D gear is much smoother, and R gear will still be a bit abrupt.
Second, before the upgrade, after starting the car, even if you step on the first foot of the throttle in ECO mode, the engine will have a short process of suddenly pulling up the speed to more than 2,000 or 3,000 rpm, that is, not rising gear. Probably the reason is that the speed after the first foot of oil to 18 km / h, after the small throttle opening to stabilize the speed, the gearbox stuck in the 2nd gear after not upshift, it has been pulling the speed. Now the new engine program has fixed this problem. After the start of the vehicle, the throttle is small, and when the speed reaches 20 km / h, it will gradually rise to the third gear to maintain, which brings better starting smoothness.
Third, the power output of the Comfort Mode and the gearbox shift are adjusted for smoother. Simply put, the comfort mode does not have the feeling of stepping on a little and stepping too much before.
It has been said that the Shadow Leopard's comfort mode is like the sport mode of other cars - too much emphasis on the power explosion that young people like, which also causes a strong power output that may occur at 10% of the throttle opening. After this software upgrade, the power output of the comfort mode returns to normal, basically the first 30% of the throttle opening will be more linear output, and the gear upgrade is positive, no longer has the previous abrupt "acceleration upshoot" situation. Unless you really step on the throttle more than halfway, you will have the output feeling of the previous old version of the program.
In addition, in the state of following the car at a speed of 20-40 kilometers per hour, whether it is lightly pressing the accelerator or releasing the accelerator, the driving experience in the comfort mode is more smooth, and it is possible to follow the car very well, and there is no longer a need to switch the ECO mode. Personal feeling is that although there will be some weak gear shift pulling feelings when sliding at a speed of about 18-25 kilometers per hour, it is already very weak, and at the same time, the power output is soft enough to not have a sudden setback before.
Fourth, manual paddle shifting in M mode seems to have improved responsiveness. Before the user complained more about two points: one is that the paddle dialed no response, to wait for a long time to have action, the other is that even if there is no upshift, to 4000 rpm or will automatically rise. After a brief experience of manual shifting after this upgrade, the reaction of the low-gear paddle shift was accelerated, at least in line with expectations. However, in the high-end position, it is still dialed to wait for two or three seconds to downshift, and the speed increase is not so obvious. In addition, the gear shift range is larger, which can be stabilized to about 5500 rpm, and will not suddenly rise to the gears by itself. Of course, this is only a short experience on the road, is it true that we will continue to test it later.
Fifth, it seems that the vehicle's sense of blocking after releasing the throttle is not so strong, especially when encountering downhill, the vehicle will have a deceleration process before the program upgrade, and now it feels that the whole process is more lightly kneaded, and the sense of deceleration is weakened.
The above five points, the first, second and third points are relatively clear feelings, and the fourth and fifth points need to be further experienced, which may also be psychological factors. But basically it can be summed up: the driving experience of the comfort mode is significantly improved, the front section of the gas front is more smooth, and the power output is more in line with daily needs. In particular, the slot points before Tip-out and Tip-in in at low and medium speeds have been corrected, which can realize the follow-up of low-speed traffic, without the need for ECO mode as the first choice for daily transportation. After all, ECO mode is still slower to respond than comfort mode when power is needed. In addition, the vehicle dynamics at the start are optimized, and there is no longer a significant sense of frustration and movement, and it is more gentle.
From this upgrade, it can be seen that Trumpchi's action for market feedback is fast enough to give corresponding solutions in a short period of time, and continuously optimize its products through software upgrades, so that its products always maintain better competitiveness. On the other hand, in addition to seeing the intentions of Chinese car companies in treating users, we must also see the agility and autonomy of Chinese car companies in the development ability, and the program adjustment on key components is becoming more and more handy, no longer the core adjustment must rely on external forces as before.
