These are two typical graphs we get when we test the AutoLink in a vehicle with a calibrated DMI sensor. A Modular Distance Sensor (MDS)
is installed in a vehicle and the sensor is carefully calibrated. An AutoLink is also connected in the same vehicle to another DMI. The outputs of the two DMIs are read by software we wrote running on a laptop. The software stores the distance and speed as measured by each system each second and then plots the data on two graphs. In this test the vehicle followed a fairly typical route that required several stops.
The top graph shows the accumulated distance as recorded by the two systems. It isn’t immediately obvious from this graph but there are two lines plotted. The second graph is similar, but
shows the variations in the speed of the vehicle. You can see that the two graphs show that the AutoLink data tracks the MDS data almost perfectly. At this scale you really can’t see any error. (We
will have more, comprehensive testing results available at a later date.)
