The new-generation all-wheel drive system that is i-ACTIV AWD uses a pro-active approach to controlling the amount of power that goes to all four wheels in order to realize its vision of being a fully-autonomous AWD system. The obsessive sensors can detect the tiniest of variations in wheel speed, things that a mere human could never hope to notice. At the same time, the robo-brain understands constantly changing road conditions by monitoring variables like weather, temperature, steering torque ratios, and slope degrees.
Using this information, the system proactively controls the distribution of torque, thereby keeping handling solid and predictable. For this, the sensor checks the pressure of the brake fluid. Remember, the sensors can monitor the vehicle and its surroundings for times per second and deliver the needed actions before the driver can even see the upcoming obstacles. The system is also aware of the weather conditions outside the vehicle so it can consider the possibilities it might encounter along the way.
The wipers are on, it is probably raining. If the temperature is cold outside, it is probably snowing. With this, the system can measure how slippery the road or any surface is by comparing the amount of current that goes through the electric power steering with the steering torque and the inclined part of a slope by the degree of acceleration.
The system also measures with exactness the speed of all four wheels and sets out an alarm or a warning sign that the wheels may be in danger of slipping. When in a dry surface, it then minimizes the torque sent to the rear wheels making it like a front-wheel drive that has a great fuel economy and emits less carbon dioxide.
All of the things needed to make sure that the vehicle maintains its optimum control, stability, and forward momentum. This in turn, warns the system for a potential tire slip. It also enables control drive force with a high level of accuracy. While the Front-wheel Slip-warning Detection System sensors, calculates and detects, the Torque Control System is the one responsible for reacting instantaneously. It immediately responds to the call of warning by transferring the needed amount of torque to the rear wheels even when the vehicle is in a front-drive setting.
This allows a smooth and prompt transition to All-Wheel Drive mode immediately after receiving a command to send torque to the rear wheels. To make it simple, the system distributes the torque to the front wheels when the vehicle is driving in a perfect road and weather conditions and sends torque to the rear wheels that functions the All-wheel drive mode if a wheel slip is detected and the driving road condition becomes progressively worse.
It is the same technology that gives your vehicle the best amount of traction no matter what surface it is driven on. The distribution of torque to the front wheels when the rear wheels are not needed also helps lessen the fuel economy. Mazda made sure that you will still be able to have a fun ride across all possible scenarios.
It comes as a standard feature on the higher trims but it is optional for the lower trims. Here are the list of trims and models that offer AWD:. Then, the vehicle has to react to the problem and apply a brake or clutch to transfer power to the remaining wheels. What has been needed is an AWD system that is truly predictive — one that measures more than just wheel speed and engine power to decide where to apply torque.
By monitoring 27 different sensors over times per second, i-ACTIV AWD considers not only wheel speed and engine dynamics, but g-forces, driver inputs to the braking and steering systems, outside temperature and even windshield wiper activity. By constantly monitoring different factors around the vehicle, i-ACTIV AWD is able to predict upcoming conditions, allocating engine torque to the necessary wheel to maintain control, stability and forward momentum.
