Tracking the driving forces

Case: AMG Torque Control Application

Tracking the driving forces

For Mercedes-AMG GmbH, a wholly owned subsidiary of Mercedes-Benz AG; we created an animated touch application of the power distribution of an innovative rear axle transmission.

This cinematic representation was presented to numerous media representatives from all over the world as part of the International Press Driving Event for the Mercedes-AMG A 45 S and CLA 45 S models at the Circuito del Jarama in Spain. In keeping with the location, the animation depicts prominent points on the racetrack so that the knowledgeable media representatives could understand what was happening technically in the vehicle even before their first test drive on the racetrack.

The key element is the new rear axle transmission. Inside it is the AMG TORQUE CONTROL – two electronically controlled multi-plate clutches, each connected to a drive shaft on the rear axle. Depending on the driving program and driving situation, the drive torque is variably distributed to the left and right rear wheels. In poor road conditions, this solution provides optimum traction, i.e. even more active safety. In drift mode, the system allows easily controlled power oversteer, the famous “powerslides” and thus even more driving fun.

Representation of the route section

This animation shows the currently driven curve section of the race track and shows where the vehicle is located based on the moving point.

Angle of the steering wheel deflection

The steering wheel’s impact is visualized by the illustration’s moving front wheels, but also by a dynamically changing percentage of steering intensity. Both animations were coupled to each other here.

Operation of the gas pedal

The speed of the ride is visualized by the centered animated icon of an accelerator pedal, which at the same time determines the intensity of movement of the point on the track.

Distribution of drive force to all four wheels

The red bars visualize the drive force, which is transmitted to each wheel as required depending on the section of road and the driving situation (AMG Performance 4MATIC+ variable all-wheel drive). A new feature is that the power is distributed not only between the front and rear axles, but also wheel-selectively between the left and right rear wheels at the rear.

Data becomes movements

From the data provided by AMG, we visualized animations for acceleration, steering angle, drive force and torque distribution of the axles on the vehicle illustration, which dynamically adapt to the driving behavior and the curves of the race track.
