Next generation Mazda engineered handling upgrade provides more precise natural steering and handling feel. Wayne Gerdes – CleanMPG – July 13, 2016 Mazda’s Dave Coleman, R&D Vehicle Development Engineer and one of the best suspension tuners in the business explains G-Vectoring Control in detail. Mazda announced its SKYACTIV-VEHICLE DYNAMICS, a series of new-generation vehicle motion control technologies. The first in the series, G-Vectoring Control, will be introduced across Mazda’s entire model range, starting with the updated Mazda Axela (Mazda3 here), which goes on sale in Japan today. The first North American application will come later this year in the 2017 Mazda6 with the 2017 Mazda3 receiving it and arriving shortly afterwards. Part of the SKYACTIV Technology suite, SKYACTIV-VEHICLE DYNAMICS provide integrated control of the engine, transmission, chassis and body to enhance the car’s “Jinba Ittai” feel—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. The degree of control is extremely subtle, with a reaction time from the moment the driver begins to turn the wheel as little as 1/10th of a degree and far faster than a person can perceive, the resulting deceleration force is usually at or below 0.01 G. One of the key features of GVC is that it enhances a natural driving feel by offering quicker and more precise control than is possible for a human driver. 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. With GVC, Mazda vehicles will exhibit even smoother transitions between G-forces in all driving scenarios. 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.
