ValueAtTime

Here is a code snippet that will compute the steering wheel angle at T=2.4s.

>>> val = ValueAtTime (label   = "Steer Wheel Angle @ T=2.4s",
                       measuredValue =  "RTOD * AZ(77,66)",
                       atTime        = 2.40,
                       delta         = 0.1,
                      )

The calculation in ValueAtTime is implemented for this example as:(1)

$$\begin{array}{l}\text{f(t) = measuredValue}\\ \delta \text{(t) = Step (time, atTime-delta, 0, atTime, 1) + }\\ \text{ Step (time, atTime, 1, atTime+Delta, 0) - 1}\\ \text{response = }\frac{{\displaystyle \underset{to}{\overset{tf}{\int }}\text{f(t) }\delta \text{(t) dt}}}{{\displaystyle \underset{to}{\overset{tf}{\int }}\delta \text{(t) dt}}}=\frac{1}{\text{delta}}{\displaystyle \underset{to}{\overset{tf}{\int }}\text{f(t) }\delta \text{(t) dt}}\end{array}$$
