Mazda G-Vectoring
The possibility of influencing the curve behavior of vehicles not by the brake system (ESP), but by motor torque, is known as 'Torque Vectoring'. In Mazda's new
'G-Vectoring', the engine plays an important role, too. In this case both, increasing and taking back torque is important.
Naturally the influence can not be as great as with Torque Vectoring. It is hardly noticeable when driving, but can be covered by performance tests. It assumes that
changes in the torque can effect wheel loads, in curves, of course, at the curve outside wheels. In principle, they could have an effect at any loss of traction.
Sensors for steering angles, lateral and longitudinal acceleration are already available in many vehicles. A link between the steering sensor system and the
motor actuatoric, which helps to reduce '(unconscious) steering movements' and 'power peaks'. Very fast changes of the engine torque are usually by changing the ignition times, more slowly achieved with the air/fuel
supply.
Front wheels are more heavily loaded by reducing, rear wheels by adding torque. As a result, the vectors that affect the center of gravity can be influenced., e.g. to giive a wheel more traction and/or to influence
over-/understeering or to avoid unnecessary corrections or forces on the steering wheel. 10/16
