Slideslip Angle Estimator (SSE)

Addfor developed an algorithm called “The SideSlip Angle Estimator” to estimate the Drifting Angle of a Vehicle.

The SideSlip, also known as “Beta” or “Drifting” angle, is the angle between the longitudinal axis of the vehicle and its speed direction. This angle cannot be measured with standard sensors, but it is fundamental for the modern Traction Control Systems.

Addfor developed a high-performance estimator based on the Deep Learning technology that outperforms the commonly known Kalman filtering approach.

Performance Traction Control (PTC)

The Performance Traction Control is an algorithm developed by Addfor to maximize the vehicle’s performance in every driving condition, which ensures the maximum acceleration available in exiting turns.

Hight-Precision Speed Estimator (HPSE)

The High Precision Speed Estimator is an algorithm developed to estimate the speed of a racing car with high precision.

Although the vehicle’s speed is a standard signal provided by every ECU, in the racing applications a higher precision is required for braking.

Currently, most of the teams calculate speed through a heuristic based on the vehicle’s accelerations to take the wheels slips into account. Unfortunately, this approach is sub-optimal, especially in heavy braking and traction conditions, where a precise estimation of the vehicle’s speed is most required.

Moreover, on vehicles using commercial electronics derived by production ECUs, the wheel’s speed is affected by the correction factors applied by the electronics providers. Those factors are adapted for the typical uses of the vehicle and usually they are not documented by the ECU’s manufacturer.

Our algorithm transforms the angular speed in longitudinal speed by calculating the rolling radius,the wheels slips and the tires’ centrifugal deformations.

We developed a high precision algorithm to estimate the vehicle speed with a maximum RMSE of 1% from 10 to 40 km/h and with an RMSE below 0.5% from 40 to 310 km/h.
