An ingenious new Mazda technology called G-Vectoring Control emulates race-car driver weight-transfer techniques to make road-going cars driven by mere mortals handle better and make passengers feel more comfortable. Every time the driver turns the steering wheel, GVC shifts a tiny amount of weight to the outside front tire, which improves grip and steering response. The result is less sawing at the steering wheel to find the right path through a turn, or less effort to keep the car pointed straight on the highway. G-Vectoring Control is not just another over-hyped modest performance tweak. Mazda appears to have developed a significant electronic driver enhancer. The driver and passengers will subconsciously believe the car handles better it actually does and the driver is a better driver possibly. It is a significant step forward for Mazda in making mid-price cars and crossovers carve corners like high-end German sport sedans and maintain arrow-straight stability on long, straight highways. Mazda G-Vectoring Control debuts on 2017 Mazda 6 and Mazda 3, with the rest of the line to follow over the next couple years. How it works instantaneous change to ignition timing When a car slows or brakes, the weight shifts forward. That's physics. The weight transfer puts weight on the front wheels, so they grip better and turn in a little more. Race drivers are taught to brake just a little heading into a turn to initiate the weight transfer. Mazda GVC automates the process. As soon as the driver turns the wheel, Mazda's SkyActiv engine management system - which includes the GVC algorithms as part of what Mazda calls SkyActiv Vehicle Dynamics - retards the ignition timing ever so slightly, engine torque power falls slightly, the car slows ever so slightly, and a small amount of weight transfers to the outside front wheel such as the right front wheel if the steering wheel is turned to the left, as in the illustration above. All this takes place in less than 50 milliseconds one-twentieth of a second from steering wheel input to torque reduction, so it's effectively instantaneous. A Formula 1 race driver couldn't do all that in 50 ms. The change in speed is so slight, to Mazda says, that "deceleration is not consciously detectable by the driver." The amount of weight transfer is at most 10 pounds, but it's enough. Mazda found that using the brakes to slow the outer front wheel took too long and was imprecise too much or too little braking, as did slowing the engine in other ways, such as reducing fuel flow. [video width="640" height="360" mp4=" How it feels behind the wheel Mazda set up a series of demonstrations in Monterey, CA, at the Mazda Laguna Seca Raceway using a set of instrumented Mazda 6 sedans outfitted with an on/off button for GVC, and a laptop-equipped backseat technician that videotaped and recorded steering wheel input for back-to-back laps with GVC on, then off. The A-B testing included a emergency lane change slalom, an oval, a water-soaked high speed turn, and a narrow lane set off by cones on one side and the famous racetrack's unforgiving concrete wall protecting pit road. The video above shows a 30-second oval driven at the same moderate speed with G-Vectoring Control on and off. Notice the more frequent micro-corrections of the wheel with GVC off. With GVC disabled, the driver is likely to turn in too much or too little, over-correct, correct for the over-correction, and so forth. Those more frequent sawing motions at the wheel are on the right video. The line chart shows the greater smoothness with GVC enabled blue line, especially the first half of the lap. Where the blue line diverges in the middle, I swung wide to set up for the second turn, a no-no; drivers were supposed to hug the inside of the course all the way around, each lap. On the oval the most notable difference was how little steering input corrections I had to make going around the turns. On the long narrow lane on the track's main straight, the difference was how stable and centered the car seemed, almost as if the lane was a couple feet wider. On the highway, that should translate to a car that seems to go where you want it to straight ahead with fewer corrections. [metaslider id=230844] Back story equilibrioception and minimum jerk theory Mazda has been working on GVC for eight years, much of it in conjunction with Hitachi, according to Mazda vehicle development engineer Dave Coleman. That included deep-dive research into how drivers and passengers react to the forces of motion. One topic of study was equilibrioception, or how people maintain and lose their sense of balance. People walking or running like to keep their heads straight upright the brain corrects for normal head bobbing, and doing that serves as the body's internal G-sensor. See the YouTube video Chicken Head Tracking below for proof that other parts of the animal kingdom want to keep their heads straight up, too. The minimum jerk theory was also studied and, no, it has nothing to do with who's likely to win Election 2016. Basically, human motion includes jerky motion that we try to smooth out as much as possible. Driver and passenger are upset by jerky motion, which Mazda says is not velocity going a steady 60 mph even though the roadside looking out may be a blur, nor is it the delta change in velocity, which is described as acceleration. Rather, "jerk" is the change in acceleration, and it shows itself in repeated sharp little steering wheel adjustments, or pressing softer then harder on the brakes, or pressing more then less on the throttle. With a turbocharged car, when you tromp the throttle, the car moves off and the jerk moment comes a fraction of a second later when the turbo boost finally takes effect. Jerk motion is unsettling. Turning into a corner involves at least a small jerk, and each time the driver corrects again, there's another jerk. With GVC, there are fewer mid-turn corrections. G-Vectoring Control vs. torque vectoring Mazda says G-Vectoring is not the same as torque vectoring. Torque vectoring is a mechanical or brake-induced action to over-drive the outer powered wheel going around a corner, effectively powering the car through the turn. Mechanical torque vectoring can add 100 pounds or more or weight to the car not to the driven outer wheel. Brake-controlled torque vectoring brakes the inside wheel, effectively overpowering the outer wheel in comparison. According to Mazda chart above, G-Vectoring Control has the advantage of working in more situations than torque vectoring, most of all in everyday conditions where it makes the car seem more stable and on-course. Why G-Vectoring Control matters Mazda is an engineering-driven company that sees itself the equal of Toyota or Honda, albeit with one-fifth the sales. To close the sales gap with them and at the same time try to be thought of as a mid-priced BMW competitor, Mazda does intriguing things with software to make its cars drive better and react more quickly than even the most skilled driver can. Thus, G-Vectoring Control. Before GVC happened, Mazda tuned its i-Activ all-wheel-drive system for what it believes is best-in-class winter driving, employing several dozen sensors to capture and respond to wheel-slip before even the driver notices it, again in a few milliseconds. In a series of tests in mountainous Colorado at the Mazda Ice Academy photo inset, the Mazda CX-5 conquered hills and slippery slaloms better than competing SUVs. Admittedly, on courses Mazda designed. Based on a day of driving several Mazda cars at Laguna Seca, Mazda makes a strong case that GVC is a feature you'll want to have. It's one more part of Mazda's pursuit of Jinba Ittai, a Japanese phrase that roughly translates to "horse and rider as one," "oneness between car and driver," or the car as an extension of the driver's desires. When can you buy GVC? Mazda says G-Vectoring Control will first be available on the 2017 midsize Mazda 6 sedan and the compact Mazda 3. Mazda will outfit the entire line within "a couple years." It's not possible to retrofit current Mazdas. While it's a software enhancement to the Mazda SkyActiv engine control module, there are also subtle tweaks to the suspension and steering. GVC will eventually be on all Mazdas, standard, and unlike the test cars, they'll be always on no off button. An interesting possibility is what happens if other automakers want GVC to use on their cars. So far, Mazda hasn't said if it would license GVC or a variant. There have been times in the past when one company had a technology everyone else wanted, such as Mitsubishi's counter-rotating balancer shafts that reduced the vibration inherent in four-cylinder engines.

By Rianna Thurling 15 November 2021 Along with the release of the Mazda3 and Mazda6, Mazda has unveiled their latest advancement in driving technology – G-Vectoring Control. Inspired by the philosophy of Jinb a-Ittai horse and rider as one’, Mazda has endeavoured to give drivers even greater control and feedback when braking, accelerating and turning. How does G-Vectoring Control Work? This first addition to the SKYACTIV-VEHICLE DYNAMICS series offers drivers greater control over the car by adjusting the lateral and longitudinal acceleration forces together. In doing so, the engine torque is adjusted in response to steering inputs and controls the vertical loading on each tyre. When the car begins turning, the vertical load is shifted to the front tyres by generating a deceleration G-force. As a result, the front-wheel grip is increased, improving the vehicle’s responsiveness. If a consistent steering angle is maintained, the G-Vectoring Control recovers the engine torque, transferring the load to the rear wheels to enhance stability. These small adjustments offer the driver greater confidence in the car’s ability to follow their intentions, reducing the need for corrections. However, the subtlety of G-Vectoring Control means there is zero driver or passenger discomfort. The Benefits 1 Increased Driver Confidence The innovative G-Vectoring Control Systems allows drivers to feel confident that the car will follow their intended line precisely. This applies not only to turning, but also to the minute changes in direction caused by road surface irregularities. The slight force redistribution made by the G-Vectoring Control greatly reduces the need for driver corrections. 2 Reduced Fatigue The need to constantly make minor – often unconscious – corrections while driving is one of the key factors that contributes to driver fatigue. On long journeys, the reduced need for corrections created by the G-Vectoring Control means drivers will feel more alert. 3 Increased Comfort On top of reduced fatigue, the G-Vectoring Control System creates a smoother transition between G-forces. This reduces body and head sway, providing a more comfortable ride. 4 Greater Peace of Mind The ability of the G-Vectoring Control to enhance both handling and stability simultaneously also provides improved control in adverse conditions. When driving in rain, or on ice, snow or poor road conditions, G-Vectoring Control helps to stabilise the vehicle and improve the tyre grip. This increased stability will give drivers peace of mind in any conditions. 5 No Additional Weight As G-Vectoring Control is a software-based technology, it requires no additional space or weight. Instead, it utilises Mazda’s SKYACTIV-engines, SKYACTIV-transmissions and SKYACTIV-chassis to create this improved G-force distribution. G-Vectoring Control is available now in both the Mazda3, Mazda6 and all-new Mazda CX-5.

Since G-Vectoring Control GVC was introduced in the 2017 Mazda 6, it has since been included as standard for all its vehicles. While it is mostly known as “the” Mazda technology that aids in the driving experience of the brand’s cars, there is little understanding on what it does, and why it is a highlight for Mazda. In this article, we will break down the points of GVC – from its benefits to misconceptions. How did G-Vectoring Control come about? The word Jinba-Ittai’ is a saying that is at the heart of every Mazda. First seen in the brochure for the first-generation Mazda MX-5, Jinba-Ittai’ basically translates to “the feeling of connectedness between a rider and his horse”. When put in context of the brand – it basically translates to harmony between a car and its driver. Marrying the Jinba-Ittai’ concept plus the focus on being innovative and striving to be better, GVC was introduced to improve chassis performance by controlling the engine output; but developed based on Mazda’s human-centred development philosophy. What is G-Vectoring Control? To put it simply, G-Vectoring Control is an electronic system that ties the power steering and engine control computer together. When the steering wheel is turned, GVC reduces engine power slightly. The resulting effect pitches the front of the vehicle forward, putting more load on the tyres and allowing the car respond directly. All this translates to a more stable vehicle for both driver and passengers. What are the benefits of GVC? There are several, but the most important is that GVC is highly versatile and can be deployed in any Skyactiv Mazda’s latest technologies that encompass the brand’s engine, chassis, transmission and car body model, irrespective of drive system or vehicle type. Additionally, since GVC is a software control system, there isn’t any increase in weight. However, the main points are Increase in driver confidence due to reduction in steering corrections with GVC. Passengers feel more comfortable because GVC smoothens the G force transitions that suppresses the swaying of head and body. The enhanced handling and stability on various road surfaces including rain and snow gives a greater sense of security to the driver. Less slip equals more traction and driving confidence. Why is vehicle control important? “If you want to get a driver’s license, you can go to a driving school and get basic driving lessons. But those lessons do not educate you on the importance of vehicle control and ways to improve control. For instance, driving instructors do not teach you on controlling a vehicle for better or more efficient driving. GVC ensures the vehicle controls its dynamics on an extremely minute level, not capable by drivers themselves, so that driving efficiency is significantly improved,” said Daisuke Umetsu, vehicle development division, Mazda. Does this mean that GVC is a standalone technology to improve vehicle dynamics? No, it isn’t. Because GVC ties both steering input and engine to optimise load control, the technology could not have been achieved without the brand’s Skyactiv engine. Both of Mazda’s Skyactiv-D diesel and Skyactiv-G petrol engines are capable of extremely fast and precise control, which realises optimum torque control requested by the driver’s steering input. In simple terms, this means that the engineering that has gone into the suspension, body, seats and steering all come together with the system, which is needed to carry the load and reach the road surface. The all-new Mazda 3 now comes with G-Vectoring Control Plus. What does the update do? “On top of shifting the weight to improve grip and make the car behave more naturally, G-Vectoring Control Plus also works when you’re coming out of a corner. We apply a tiny amount of brake to the outside front tyre to help straighten the car as you exit a corner,” explains Dave Coleman, vehicle development engineer at Mazda R&D.

Sell your car to Carsome and upgrade your ride to a Mazda! AtMazda, we’re in constant pursuit of making driving better. That’s why we developed a new technology, SKYACTIV-VEHICLE DYNAMICS with G-Vectoring Control, to help achieve a smoother, less fatiguing drive. When cornering, on initial turn-in and throughout, the system works seamlessly by adjusting power delivery and shifting vehicle weight.In modern vehicle design, electronic control systems are central to, well, everything. Certain luxury car models are now equipped with upwards of 70 ECUs that are responsible for safety systems, stability control, and even moon roof operation. However, not all systems are designed for basic functionality. Mazda's engineering group has been working on variations of "GVC" G-Vectoring Control for the past driving the latest Mazda CX-5 and Mazda 3 with "GVC" it was hard to identify what the system was doing. After studying "GVC" and understanding how it worked, I was able to get the vehicle in snow to further test it. I immediately summarized the operation of "GVC" as a "torque reduction system." The ECU of the vehicle is looking at reducing the torque output of the motor to help transfer a small amount of weight onto the front wheels during cornering which reduces the G-load on the passengers and also helps keep the vehicle on it's intended path. To most people the ECU torque adjustment is transparent however, driver steering effort changes. "GVC" is so intuitive that it helps reduce micro corrections or changes to the steering angle in the middle of the turn which is the primary reason for smoother 3 with GVC, SavageGeese Steering Effort Reduced, Steering Effort, Mazda The concept of "GVC" was to improve driver confidence through the study of human behavior. Mazda aimed to improve the sense of control in hopes to solidify the attachment the owner has with the vehicle. The final design focuses on engine control and changing output characteristics. Those changes also required subtle updates to the suspension to maximize the overall performance. "GVC" is cannot be turned off and is baked into the engine programming.Intended Path of Vehicle, Weight Transfer, Mazda “GVC maximizes tire performance by focusing on the vertical load on the tires. The moment the driver startsto turn the steering wheel, GVC controls engine drive torque to generate a deceleration G-force, therebyshifting load to the front wheels. This increases front-wheel tire grip, enhancing the vehicle’s turn-inresponsiveness. Thereafter, when the driver maintains a constant steering angle, GVC immediately recovers engine drivetorque, which transfers load to the rear wheels, enhancing vehicle series of load transfers extracts much more grip from the front and rear tires, improving vehicleresponsiveness and stability according to the driver's intentions.”Mazda ENG
