Specifying lateral potential of the vehicle as input trace

The handling option is to generate the possibility to analyse cornering behaviour in combination with road uneveness's.

In order to keep the input simple, the approach is chosen to specify a lateral potential signal. The model tries to achieve this lateral potential, regardless of any driving line.

Simulating driving on a grip circle

The first option is to give a constant value for the lateral potential.

The start and end point of the lateral potential value are flexible. In this manner one can make a manoeuvre with and without cornering in one area.

Analysing the frequency response of the vehicle

The second option is to give the model a (variable) sinuswave as input for the lateral potential signal.

By varying the frequency, a kind of frequency swap can be made. One should not compare these results with slalom driving. That requires a completely different input.

We would not advice to combine this input with road uneveness's.

Combining left and right turn

The last option is a varying positive and negative signal, simulating a left and right turn.

The duration of both the left and right turn can be altered as well as the frequency with which the signal changes.
