A 2D outline of a test vehicle can be created using the RT-Range polygon tool. By creating a polygon of the vehicle you get a more representative view of the vehicle during tests than a single measurement point will provide.
For advanced vehicle safety tests such as Blind Spot Detection and collision detection at junctions, RT-Range computes the distance between the 'Hunter' vehicle and various points around a target vehicle's polygon. This is illustrated below for a Park Assist scenario.
Fig 1: RT-Range computes distances between a Hunter vehicle, and the closest point on a target vehicle.
Create a polygon for your test vehicle and upload those measurements into RT-Range
The RT-Range software application requires users to input the specific polygon for their test vehicle. This is done either by selecting 'Use Polygon' in the Car Range measurements window of the RT-Range application and inputting measurements individually, or by uploading a file. We have created a tool using Microsoft Excel which enables you to input your polygon points more easily.
Using the Microsoft Excel polygon creation tool
- Download the Excel workbook attached to this article. Save this to a place on your PC.
- Follow the instructions in the workbook in red text, starting on the vehicle polygon tab. Enter the total length and total width of your vehicle to begin with. The 'origin' is the measurement point of the rear centre of the vehicle - this should be 'zero'. Complete the table for the number of polygon points you want to use. The preview image will change to display your vehicle polygon.
- Convert your measurements into the format required for uploading into RT-Range. On the 'Code' tab, create a Text File in *rtrp format by clicking the button provided. A Notepad file containing your measurements will appear in the same place you saved the polygon creator tool.
- To upload your file click 'Load' in the RT-Range 'Hunter polygon' window, then select your saved file.
