RT-Range S

for complex, multi-vehicle ADAS tests to NHTSA, EuroNCAP & IIHS standards



As testing advanced driver assistance systems (ADAS) is getting more complex, car manufacturers need a system which can perform a range of complicated tests including multiple vehicles in realistic traffic scenarios. The RT-Range is one of the most trusted and comprehensive solutions used globally for demanding ADAS tests such as NHTSA FCW, LDW or EuroNCAP Autonomous Emergency Braking.  

The RT-Range S is used for two functions: accurate measurement of the relative motion between two vehicles and precise measurement of lane position. All measurements are online, in real-time and output on a CAN bus, including the Target vehicle measurements being relayed in the Hunter vehicle's CAN bus.

Verifying the accuracy of radar and other sensors can be performed subjectively. The RT-Range S is a precision tool for evaluating these measurements numerically and objectively.

Vehicle-to-vehicle Measurements

Vehicle-to-vehicle measurements are performed by measuring the position of the two vehicles and then transmitting the position of the Target to the Hunter using Wireless LAN radio. This is fast, has very low delay and can be used worldwide, license-free. Any additional delays or lost packets from the Target are extrapolated with minimal loss in precision.

The position of the radar (or sensor) on the Hunter can be defined at any location. Similarly, the measurement point on the Target can be defined at any point. There is no need to mount the RT products at special locations in the vehicle. These measurement points are independent of the Lane Position measurement points.


Lane Position Measurements

There are three steps to measuring Lane Position. First the lane markings are surveyed; then up to 8 lane markings are combined into a map; finally the actual vehicle position is compared to the map. This leads to exceptionally accurate and reliable Lane Position measurements. All the tools to survey the lane markings and build the map are provided.

The measurements from three points in the vehicle are available simultaneously. This allows the system to test several sensors at the same time. The RT-Range S automatically selects the correct lines in the map and measures to them.

The RT-Range S also computes the reference distance along the map so that graphs can easily be overlaid.

Multiple targets

track up to 4 targets whether they’re vehicles, cyclists, or pedestrians; static ones like parked cars; or feature point targets like road signs.

User definable vehicle shape

Realistically recreate the shape of Hunter and Target vehicles as polygons with up to 24 points. The RT-Range S automatically calculates range measurements to the nearest polygon point.

Driving robot interface

dedicated driving robot interface for maximum reliability, unparalleled accuracy and repeatability.

Open road ADAS testing

receive DGPS corrections via NTRIP.

Car-to-pedestrian testing

The RT-Backpack is a complete turnkey target system in a backpack that can be carried by a pedestrian. Capable of tracking the position of pedestrians relative to a moving vehicle.

CAN bus data

The RT-Range system now has real-time CAN display and logging capability. Log CAN data to one file from multiple vehicles in seconds.

Fast Installation
The RT-Range S can be installed quickly into a vehicle. Training is simple and the system is very easy to use. Results can be obtained within hours of receiving the equipment.

On-site training can be provided to help engineers get to work quickly.

Advanced Driver Assistance Systems
The versatility of the feature rich RT-Range S makes it one of the most popular systems for ADAS test and validation.

Adaptive Cruise Control
Real-time output of distance-to-target and relative velocities makes RT-Range S systems perfect for testing and validating adaptive cruise control systems.

NHTSA LDW (Lane Departure Warning)
The RT-Range S easily and reliably captures the data required to develop, test and validate LDW systems by tracking up to 8 lanes.

NHTSA FCW (Forward Collision Warning)
Track several targets with 2 cm accuracy in real-time when developing, testing and validating FCW systems.

Blind Spot Detection
As well as displaying distance and velocity to targets, the RT-Range S also displays percentage of a target that is visible.

Euro NCAP AEB (Autonomous Emergency Braking)
Whether you perform tests with moving or static targets, the RT-Range S is your tool of choice. An improved interface now allows data from a static target to be output to ABD robots during tests.

Intersection Assistance
Reliable real-time communication between vehicles up to 1 km and the ability to tack mobile and static targets allow the RT-Range S to evaluate most traffic scenarios.

Rear Collision Warning
Instantly view information about the relative position and velocity of each target, which can be defined with up to 24 points and tracked with 2 cm accuracy.

150_SurveyTrolleyFor lane tracking tests, OxTS has a dedicated survey trolley that can be used to survey lane markings and software to capture each line and add it to a map.

The survey trolley is designed to keep the GPS antenna high, so the accuracy is not reduced by multipath (caused by reflections from a person above it). The survey trolley also carries a battery, laptop computer and an RT. The survey is done by using one of the survey trolley wheels as the measurement point, which gives the user the best chance of achieving the highest accuracy.

The line survey software can be used to store the straight or even curved line measurements into a file and turn it in to a map. The map can be downloaded in to the RT-Range and then the lane measurements begin.








The line survey software is shown here









After the lines have been captured, they can be turned into a map using the Map Creation wizard, see
