Lada Vesta — version 2.0: robot reboot!

On the West there is a new robotic box — AVTOVAZ has dubbed her the AMT 2.0. Well, not new — updated. One of the cars with this robot “the wheel” managed to get to discover.Kirill mileshkin “Behind the wheel”

Finally! Problems the robot was missing, and we knew about them better than many, because in the editorial more than two years, Vesta lives with a robot. But — Shh! — the plant has released an updated robot “no dust, no noise.” Just started to sell cars with AMT 2.0. Information — zero. Take the car at the factory is also unrealistic. About the new robot not a word was said even at the presentation of the sedan Vesta Cross (ZR, No. 7, 2018).

And here in the yard of our editorial appeared Lada Vesta SW Cross, courtesy of a private owner. On the odometer 2300 km, the condition of the car perfect. And most importantly: under the hood — modernized robot. Take a couple of drafting Vesta sedan with the “pre-reform” box, and hit the road.

1. Robot version 2.0 was much nicer. The main drawbacks of the box is fixed, although with the advent of the “creeping” mode is back, the question of resource chaining. The answer will give time.

2. The selector of the transmission control of the former. “Winter” mode means that to include the second transfer need and before every start. Separate keys are provided.

3. Acceleration to 100 km/h, according to official data, has not changed.

Crawling out of here

Noticed changes almost immediately after leaving the gate edition. As I lacked a “crawling” mode Creeping Mode all two and a half years of marriage with Vesta! Especially when Parking in a confined space in the winter, when under wheels ice. The car began to move only after pressing on the gas. Now the robot acts as a classic machine: to make the car go, you press on the brake pedal. And the thrust is enough to overcome without pressing on the gas “bumps” to which the front wheels are close. So with winter and snow-ice mounds in the yard, the robot will do fine.

Vesta is moving not as fast as machine with classical fluid mechanics. Box a second, thinks, then slowly enables the transmission and only then starts the movement. I noticed only one joint of a robot version 2.0: car starts, will drive the engine tremble, as if an inexperienced driver has not yet got used to the mechanical box. On the one hand, this is understandable. In “crawling” mode for large engine speed to anything, the car should pull away smoothly, without jerks, so you need a smooth closing of the clutch with a minimum flow of gas. Electronics tries, but to wield a grip need even more tender. The tremors aren’t too pleasant, and the aggregates from this treatment it is not good. Therefore, pushing in the tube, it is better not to twitch, “creeping” 20-30 centimeters. And when maneuvering in the yard and in the Parking lot “crawling” mode.

“Crawl” the West can and forward, and back. The speed that supports automation, depends on the included transfer. The first is 7-8 km/h, the second — 14-15 km/h on the back — 5-6 km/h. Provides protection “from the fool”: the mode is deactivated, if you put the car on the handbrake or open the driver’s door. Checked — working properly.

To editorial West a bit annoying the algorithm of the system of assistance when starting on the rise. After releasing the brake pedal the brakes a couple of seconds to hold the car from rolling back back to the driver managed to quietly move his foot from the brake to the gas. Feature is configured in such a way that small deviations of Avtomatika “sees” and therefore does not work. For all the time that Vesta off the Assembly line, this feature “protivootecona” cure — Vesta with the updated robot at the start of the hill is also walking backwards. And you should not rely on “crawling” mode: when the brake is released the control system first gear slower than the command from the accelerator pedal, the car manages to roll back over. So in a jam on a small rise would have under the old scheme to push the car the gas pedal.

Not slowing down!

To start with the second gear still the robot is not allowed. Because of this, the ice sometimes had unwittingly slip. Now in a control unit implemented the “winter” algorithm. Just do not look at key West with snowflake near the selector box. The second transfer is necessary to include his own, moving the lever to the manual control mode. After dergone the “creeping” mode, I was skeptical, but in the winter the car starts quite confident — although, of course, with the right pedal. Credit!

The third revision is the most important, in my opinion. The slowness when changing gears was the second main reason for complaints to the box after the fragility of the clutch (it was strengthened in the past year). The switching time was reduced due to the change and optimization of the algorithm enable the servos regardless of engine speed.

Box really began to “click” faster, it is noticeable even to the layman. The switching time depends on the transmission and how hard the driver presses on the gas. On average, minus 30% compared to “pre-reform” version. For example, the robot spent on the transition from first to second when driving, “the third pedal” 2.6 seconds, the new is 1.8. If you click the “in floor” options are 2.0 and 1.3 seconds respectively.

Box became faster to switch not only up, but down! Disappeared annoying (and sometimes dangerous) delays, when after a smooth speed reduction step on the gas, and electronics a few seconds wondering what speed she needs to include. I carefully modeled the potentially problematic situation, but the AMT 2.0 did not succumb to provocation: either in advance switched down (unlike its predecessor), or promptly tucked the desired level. And all this with a cheerful Peregudova. If not for the dull engine sound, which is disgusting accompanies the ringing of the resonator, Vesta robot could please even the discerning driver.

Yes! The words “fun” and “robot” now may well be combined. Of course, with an eye to a coordinate system. Box still plays and the classic slot and the robot with two clutches, and variators. Nothing can be done — constructive like this. However, the progress is obvious. It is a pity that we had to wait almost three years.

While an upgraded box only bet on Vesta with engine 1.8. In the instruction manual for the relevant amendments have already appeared. The turn — XRAY, motors 1.6 and all other models.

The revision relates exclusively to the program (“hardware” has not changed), therefore we could not ask visucam question: is it possible to reflash the old robot? The answer was categorical: it is impossible! Blocks the transmission control come on an Assembly is already present — it deals with a company ZF, which developed the actuators for the robot and helped in the debugging of software. In addition, you will have to change the engine controller, which constantly works in tandem with the robot’s controller. Theoretically nothing is impossible, but the financial cost will make the upgrade uninteresting to the owner.

However, we do not exclude that soon there will be craftsmen, offering a revision to the bypass official dealers. Clearly the demand for their services will be. I, for example, AMT 2.0 is very fancy.
