Easy Car's original second-generation GS8 fuel version is exclusively equipped with "black technology" - AVDC shadow driver, an adaptive vehicle dynamic control system that can make driving more relaxed, and the vehicle can actively adapt to your driving intentions, and only BMW, Mazda, Honda, Nissan and other international manufacturers have the ability to develop and equip.
AVDC (Adaptive Vehicle Dynamic Control) is the full name of GAC Adaptive Vehicle Dynamic Control System. Through "domain control", this system integrates MULTIPLE SYSTEMS SUCH AS, TCU, ESP, FOUR-WHEEL DRIVE, etc., and then intelligently adapts to the current state.
Adaptive vehicle dynamic stability system can be regarded as an intelligent dynamic stability system, the main function has two, one is to make the driving conditions and vehicle dynamic response more in line with the driver's intention, enhance the sense of driving confidence, thereby increasing the pleasure of control, the other is to suppress the shaking of the body when cornering as much as possible, improve the stability of the ride, increase the peace of mind of the occupants.
Adaptive vehicle dynamic control system compared to the previous body stability system, the difference point is in the "dynamic", the traditional body stability system triggered, the vehicle has slipped or out of control phenomenon; and the adaptive vehicle dynamic control system can change the dynamic performance of the vehicle in real time according to the driver's operation and the current state of the vehicle at any time, so as to achieve in the process of driving, the dynamic response of the vehicle and the driver's intention to merge into one.
Gac Motor Research Institute began research on related technologies in 2017, and the second-generation GS8 is the first model equipped with AVDC adaptive dynamic stability system, and the first model equipped with adaptive dynamic control system among its own brands.
The original intention of AVDC research and development is to not increase user costs as the premise, based on the existing hardware conditions can achieve adaptive vehicle dynamic control, so if you have to say what it is, it is just an algorithm.
There is no vehicle equipped with AVDC, the various components of the vehicle only work for their own duties, the steering only controls the steering, and the ESP is only triggered when the vehicle has abnormal sliding, lacking the ability to work together.
The vehicle equipped with AVDC integrates the functions of various components, so that they can work together through algorithms, for example, when the vehicle finds that the body of the car is shaking in the corner, it will reduce the engine torque and implement a certain braking force on the wheels, so that the dynamic center of gravity of the vehicle is shifted to the front position, and finally the driver can smoothly turn.
Speaking of which, some friends may be curious, how does it achieve dynamic monitoring?
In the process of driving the vehicle, the various components of the vehicle will have various signals, such as wheel speed, wheel angle, etc., and the vehicle will produce acceleration in all directions, and AVDC collects these real-time signals and acceleration, combines the driver's input, calculates the optimal solution, and finally fine-tune the engine's output torque, steering system, braking system, and transmission system.
At this time, the curious little friend will ask again, what is the optimal solution?
When people are driving a vehicle, when they feel fear, the vehicle has a sudden change in acceleration, and this acceleration mutation has a threshold, as long as it does not exceed this value, people will not be afraid.
The optimal solution calculated by AVDC is to make the vehicle make the minimum adjustment so that the instantaneous acceleration change of the vehicle does not exceed the threshold.
In order to find this threshold, the GAC Research Institute published 19 papers and applied for 31 invention patents, which have been internationally recognized, and based on the theory of the whole set of AVDCs, it can play a role in all road conditions.
GAC Research Institute's AVDC vehicle dynamic control system can be adjusted accordingly according to different models, if it is a sports car, you can play the vehicle's tracking ability as much as possible to improve the pleasure of handling, and for the pursuit of comfortable and luxurious second-generation GS8, it has another task.
The second-generation GS8 has a length of nearly 5 meters and a wheelbase of 2920mm, which is a big car, so AVDC's task is to make the car smoother, easier to drive, and more comfortable to sit.
How to make driving smoother? The AVDC function of the second-generation GS8 is designed with throttle sensitivity adjustment.
Adjustable throttle sensitivity, as the name suggests, is to change the acceleration attributes of the vehicle without changing the driver's pedal stroke, divided into 5 gears, and can also be adjusted to adaptive mode.
This allows the driver to get a smooth driving experience no matter what driving mode, for example, if you usually like the sport mode, but encounter traffic jams, then you definitely do not want the vehicle to rush out, and AVDC judges that the current road conditions are in traffic jams, which will reduce the throttle sensitivity, so that you can use the sport mode to smoothly pass the traffic jam.
How to make the second-generation GS8 easier?
The second-generation GS8, like many models, is designed with three steering wheel feels, which are light, comfortable and sporty, and change the strength of the square wheel.
The role of AVDC is that no matter what feel is used, as long as avdc is turned on, it can reduce the angle of the cornering steering wheel without changing the steering ratio.
As for how to do this, the simple description is to fine-tune the longitudinal acceleration and deceleration of the vehicle, realize the center of gravity of the vehicle, thereby changing the transient steering characteristics of the vehicle, and finally realize that in the same corner, the vehicle that opens the AVDC can use a smaller steering angle and roll through the corner, so the amplitude of the steering wheel is naturally reduced, and driving will become easier.
From the test data, after turning on AVDC, the horizontal swing and lateral acceleration of the vehicle in the continuous parallel line are significantly reduced.
Then for passengers, there is no abrupt acceleration when the car sits up, there is no obvious left and right swing when cornering, and the comfort is naturally improved.
It should be mentioned here that the four-wheel drive version of the model has full AVDC function, and the front-drive version of the model can also achieve 90% of the functionality, so if you want to experience the benefits of AVDC, you don't need to worry about whether you are a front-drive version or an four-wheel drive version.
AvDC's control panel is in the function settings, and the default mode is turned on. There are four modes of robust, aggressive, snow, and adaptive, and I recommend using the adaptive mode directly here.
The difference between the steady style and the radical style control is that the vehicle allows the mutation g value is different, that is, when cornering, the steady style will control the roll of the vehicle smaller, the vehicle is more conservative, and the radical style allows the vehicle to move more and the driving more moving.
Adaptive mode can be judged according to the driving behavior of the driver's current working conditions, if the current operation is more moving, it will automatically make the vehicle's swing larger, and the throttle is more aggressive.
Write at the end
The second generation GS8 of Trumpchi, a vehicle dynamic control system equipped with an independent brand, is the first time, and its appearance solves the feeling that most users will panic when driving a big car. And I think the metaphor of the shadow rider is very appropriate, it can really help you make driving easier and smoother like a driver.
For a system that is so easy to use, I also hope that GAC Trumpchi will be equipped with more AVDC functions in future cars.
