This part calculates the final longitudinal force from the combination of wheel torques (including the brake pads) and is a leftover from the previous model version.

The overall shape appears correct, but the noise in the graph suggests a possible numerical issue with the sign of the resulting longitudinal force in the calculations.

With the analysis tool (right), we can click any point in the plot and pause execution just before it’s calculated. This lets us trace the process step by step, pinpoint the issue, and fix it.

The final tire force (white, left) should smoothly transition fro m the raw tire force (green) to the available tire force (red) as the vehicle approaches a stop. Instead, it jumps abruptly from one value to the other.

The image shows unexpected instabilities in the lateral tire force at very low speeds, where the lateral force becomes insufficient to counteract lateral friction. In this case, the model must redirect the “unused” longitudinal force to be applied laterally.
