Continuing with its human-centered philosophy applied to all kinds of common driving situations so that driving joy can be enjoyed, Mazda has developed G-Vectoring Control Plus, the second new-generation vehicle dynamics control technology in the SKYACTIV-Vehicle Dynamics series. This is a series of new-generation vehicle motion control technologies that provide integrated control of the engine, transmission, chassis and body to enhance the car’s Jinba-ittai feel, giving a sense of connectedness between car and driver that distinguishes Mazda vehicles.
GVC Plus will first appear in the latest CX-5 and then be progressively included with all Mazda models. The original G-Vectoring Control (GVC) was 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.
GVC Plus takes the approach further by using the brakes to add direct yaw moment control for further enhanced handling stability. As the driver steers out of a corner by returning the steering wheel to the centre position, GVC Plus applies a light braking force to the outer wheels, providing a stabilizing moment that helps restore the vehicle to straight line running.
The system realizes consistently smooth transitions between yaw, roll and pitch even under high cornering forces, improving the vehicle’s ability to accurately track sudden steering inputs and crisply exit corners. In addition to improving handling in emergency collision avoidance manoeuvres, GVC Plus offers a reassuring feeling of control when changing lanes on the highway and when driving on snow or other slippery road surfaces.
As with the original GVC, GVC Plus requires no involvement by the driver for its benefits to be enjoyed. However, the driver will feel more in control of the vehicle, as if he or she is united with the machine. The computer works in less than 50 milliseconds to reduce torque, a time so quick that the driver would not notice the change. But it is enough to alter the car’s speed to optimize cornering characteristics and now with the use of brakes, stability is enhanced further.
