Slideslip Angle Estimator (SSE)

The SideSlip Angle Estimator is an algorithm developed by Addfor 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 is very important for the modern Traction Control Systems.

Addfor has 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 performance in every driving condition giving the vehicle the maximum available acceleration in exiting turns.

Hight-Precision Speed Estimator (HPSE)

The High Precision Speed Estimator is an algorithm developed by Addfor to estimate with high precision the speed of a racing car.
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 teams calculate the vehicle speed with a heuristic based on the vehicle accelerations to take into account the wheels slips. Unfortunately, this approach is sub-optimal in particular in heavy braking and traction conditions where a precise estimation of the vehicle’s speed is most required.

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

Our algorithm transforms the angular speed in longitudinal speed by calculating the rolling radius,the wheel slips, and the centrifugal deformations of the tire.

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
