Mazda’s G-Vectoring Control can work at speeds and in less than 50 milliseconds to beat even the most skilled driver.
Mazda is a car company well known for always doing a little more for drivers who appreciate driving dynamics. You could say, their engineers are real drivers! Now, Mazda wants to look at how to make their cars more dynamic from behind the wheel and from a passenger’s point of view.
Mazda deploying its newest piece of technology, called G-Vectoring Control (GVC), as a standard feature in all new 2017 model vehicles like the all new Mazda6 and Mazda3 range. Eventually, GVC, which is an advanced form of chassis management, will be standard on every Mazda sold, including the SUV range.
G-Vectoring Control (GVC) is new to the industry and so let us explain what it really is.
Mazda engineers spent a good 8-years developing GVC to ensure their new Mazda 3 and in the future all Mazda made vehicles will have handling dynamics like no other vehicle.
Mazda engineers spent plenty of time watching human behaviour, not only behind the wheel but also in doing something as simple as walking, running or even sitting in a vehicle as a passenger. The end result is a clever software system that reads steering inputs and ever-so-subtly reduces engine torque to the driven wheels. The result of that torque reduction, like a race car driver ‘lifting off’ on the track, is a shift of the vehicle’s weight forward. This adds more ‘bite’ to the driven tyres and therefore more grip and confidence at any speed.
The result, according to Mazda, is more assured handling and balance. That, and more certainty to the way the vehicle reacts to the road conditions, which dictate what the driver is doing with the steering wheel.
This technology is a direct result of Mazda so intensely observing human behaviour and how the body reacts to motion. Every action within the human structure is linked, so that as a vehicle tips into a corner for example, the body will do all kinds of balancing acts to try to keep the occupant’s head (and therefore eyeline) level.
Part of the SKYACTIV family
This new technology will be part of the SKYACTIV Technology suite, where SKYACTIV-VEHICLE DYNAMICS provide integrated control of the engine, transmission, chassis and body to enhance the car’s Jinba Ittai feel, which is a sense of connectedness between car and driver that distinguishes Mazda vehicles.
The first technology in the SKYACTIV-VEHICLE DYNAMICS series, G-Vectoring Control (GVC) was born of Mazda’s human-centered development philosophy, implementing the novel idea of using the engine to enhance chassis performance. It is the world’s first control system to vary engine torque in response to steering inputs in order to provide integrated control of lateral and longitudinal acceleration forces and optimize the vertical load on each wheel for smooth and efficient vehicle motion.
Optimizing the load on each tire brings the movements of the car more in line with the driver’s intentions, reducing the need for steering corrections, including many that are made unconsciously. The outstanding traction the system provides inspires confidence and makes driving more fun. Changes in the acceleration forces acting upon vehicle occupants are smoother, reducing torso sway and making for a more comfortable ride. In addition, GVC significantly improves handling and stability on wet, snowy and unpaved roads.
GVC benefits drivers of all skill levels in a wide range of situations: from low-speed urban commutes to highway driving, winding roads, and even emergency maneuvers. In addition, it is a highly versatile system adaptable to vehicles of any class and drive type. The only requirements are a SKYACTIV engine, which allows precise control over torque output, and a SKYACTIV chassis, which enables superior dynamic performance.
Mazda aims to enhance customers’ driving experience, heightening satisfaction and the “bond” people have with their Mazda vehicles. That sense of “Jinba Ittai” performance is based on Mazda’s human-centered vehicle development philosophy, which focuses on using human physiology and psychology to design enjoyable vehicle experiences based on how customers actually use their vehicles rather than merely chasing catalog performance metrics.
