U Drivers Aid
My µ-Drivers Aid is a versatile stand alone drivers aid. It can be used in a vehicle on-road, or in a test cell.
The speed signal from the vehicle or dyno can be:
· Analog ( 0-10V 0 =>200km/h )
· Counter ( Dyno pulse, or from vehicle )
· GPS ( Use a serial GPS signal )
· OBD ( Use a cheap ELM 327 Interface )
The first dialog box requires your selection of I/O type. A new feature is the Visualizer and flash warning.
The analog µ-Drivers Aid screen looks like this:
2 standard curves are implemented in the µ-Drivers Aid, FTP75 and NEDC with gear shift indicators.
The new feature make the driver aware if the vehicle is out of the limits. On top the visualizer can be seen which displays the offset as % diff from the curve, and if the lower limit is exceeded the driver trace screen becomes blue, and if the driver is exceeding the upper limit the screen becomes green.
Both these alarms is optional. Selected from the first screen.
For every second the driver is out of the limit a counter will count Driver violations.
If you want to create a custom driving cycle, just press the curve creator button. And the curve creator window will appear. Just paste your speed signal in 1Hz, and press the create trace button. After this the curve can be loaded by press, custom trace.
It is also possible to record the vehicle speed while you drive on-road, using the OBD. By select the Record Vehicle, this window will appear.
Now you will connect to the vehicle.
By pressing done another window will appear.
Here is some data from the vehicle recorded. The one you need to make the new custum trace is the speed.
The data is saved in an Excel sheet.
