Mazda Motor Corporation introduced SKYACTIV-VEHICLE DYNAMICS, its brand-new range of vehicle motion control technology, after the first system in the line-up made its global debut today. G-Vectoring Control (GVC) was launched on the 2017 Mazda 3, which went on sale this morning at dealers in Japan.
The SKYACTIV-VEHICLE DYNAMICS concept is another product of Mazda’s human-centred development philosophy. By providing integrated control of the engine, transmission, chassis and body, the ultimate purpose of GVC and future SKYACTIV-VEHICLE DYNAMICS systems is to enhance the Jinba-Ittai sensation Mazda strives for with all its models. In other words, giving drivers a strong feeling of connectedness with the car.
In a novel approach, G-Vectoring Control uses the engine to enhance chassis behaviour and with it handling as well as ride comfort. It’s the first system in the world* to vary engine torque based on steering input, thereby controlling lateral and longitudinal acceleration and deceleration forces to optimise the vertical load on each wheel. This improves traction, inspiring driver confidence and heightening driving fun. The car’s behaviour more closely matches the driver’s intentions, so it also reduces the need for even unconscious steering corrections – and with it driver fatigue. And by smoothening the transition of forces, GVC boosts comfort by decreasing torso sway.
The technology benefits drivers of all skill levels in a wide range of situations including low-speed urban commutes, high-speed highway journeys, on winding roads, and even during emergency manoeuvres. In fact, GVC is especially effective on surfaces that are rough (like unpaved roads) or slippery (due to rain or snow), where the system advances vehicle handling significantly. GVC is highly versatile, too, being compatible with any kind of vehicle as long as it has a SKYACTIV engine to allow the necessarily precise control over torque output and a SKYACTIV-Chassis enabling such superior dynamic performance. As a software based system, it doesn’t add any weight to speak of, so it’s not at odds with the gram-cutting obsession of Mazda’s engineers, either. GVC will arrive on models in Europe starting later this year.
