9.7.1.4 Speed transitions
As a standard , high speed V4 is used as the basis for the set value ramps. That means, HL and B
relate to this speed. If acceleration is to be done to another speed, e.g. V2, the calculation of the
acceleration time is done such that the acceleration is the same as in the case of acceleration to V4.
As a result the ramp times are shorter by the factor of the selected speed divided by V4. In the case of
speed transitions with a small difference this means that small ramp times with small roundings are
generated, which can result in an uncomfortable driving behaviour.
Using the following parameters, this calculation based on the constant acceleration can be avoided,
and
the required sections of the travel curve can be set individually .
Activation is done by entering values
greater than 500 msec , smaller values are automatically set to
0 and ignored by the travel curve calculator.
With this parameter, the transition time (independent of the speed
difference) can be set from V4 to one of the intermediate speeds V3 or
V2.
Here, you can adjust the ramp times and distances to the corresponding
intermediate speed individually.
