Mazda introduces an innovative control system of the vehicle.
The representatives of company Mazda Motor Corp. announced that the new car “Axela” semi-sports class included the new technology of motion control of G-Vectoring Control (GVC).
The purpose of GVC is a dynamic stabilization of movement that automatically adjusts multiple parameters of various systems of the vehicle when driving in difficult conditions, for example, when entering and exiting sharp turns.
“In the nearest future such system will have all the vehicles that will produce our company” – wrote the representatives of company Mazda in the press release.
The main problem solved by the system of GVC is a dynamic change in the torque in accordance with the actions of the driver, and the application objects, these changes are all four wheels of the car. As a result, torque is distributed in such a way as to minimize slippage of the wheels, to provide greater vehicle stability and improve traction. All this in turn impact favorably on the efficiency and hence the fuel consumption, increases comfort and safety.
For example, at the entrance of the car in a sharp turn, the GVC system reduces torque, which leads to a smooth decrease in speed. As a result, the car “nods forward” that provides a more powerful grip of the front wheels with the road surface and increases the car’s handling in this situation.
At the time of the exit of the turn system, GVC, on the contrary, increases the torque, causing acceleration. The load will be redistributed towards the rear wheels and this increases the stability of the car coming out of the turn, which probably did not notice the time experienced drivers.
This is the first time in automotive history when mass-produced car gets an intelligent system of stabilization of such a high level of complexity. Technology GVC is the first step towards developing more complex technologies called “Skyactiv-Vehicle Dynamics, control technology movement of the vehicle next generation, which controls both the engine, transmission, body parts and some elements of the car’s chassis for optimum driving in all conditions. This technology is developed by specialists of the company Mazda, in collaboration with scientists from the Technological Institute of Kanagawa Prefecture (Kanagawa Institute of Technology) and Hitachi Automotive Systems Ltd.
