System Overview

Target verification in compliance with global NCAP standards

RT Range-S extends our precise and reliable single vehicle dynamic measurement by handling the distance, direction, and relative motion of multiple vehicles. RT Range is used globally for target verification of cameras, radars, and LiDAR sensors, as well as intelligent connected vehicle testing of braking, lane departure warning, and collision prevention systems.

Measurement between vehicles and targets, as well as lane position measurement

RT Range can be used to accurately measure the relative motion and distance between up to four target vehicles and the test vehicle (VuT) or Hunter vehicle. Calculate the measurement data between vehicles at a distance of over 1 km. The system can also accurately measure the position relative to lane markings, as well as up to 60000 surveying feature points, such as traffic signals. Real time display of measurement data and output through CAN in Hunter vehicles.

Simultaneously measuring the distance to four targets

RT Range can establish a real-time network that can track up to four targets and calculate distance, collision time, and other related measurement data in real-time. The target can be a vehicle, soft target, pedestrian model, or nearby objects.

Measure the visibility of the nearest point and target

Draw the contours of the Hunter and target vehicle to create a polygon with up to 24 points. RT Range S can automatically calculate distance measurement data and target visibility between the nearest polygon points, and these features are designed to support testing of parking assistance systems and collision prevention systems.

Intelligent connected road testing

Received DGPS correction through NTRIP for testing on public roads.

Testing between vehicles and pedestrians

Use RT Backpack accessories for the complete turnkey target system inside backpacks carried by pedestrians. Can track the position of pedestrians relative to moving vehicles.

CAN bus data

The RT Range S system has real-time CAN display and recording functions. Multiple vehicle CAN data can be recorded to a file within a few seconds.

Testing System Architecture

The system connection is very simple. When conducting V2V intelligent driving tests, the front and rear vehicles achieve motion control and parameter collection through the RT Range system, and the two vehicles are connected in real-time through wireless communication. So as to achieve the intelligent networking function testing required by various regulations. By using a high-precision RT base station, achieve 2CM positioning accuracy for two vehicles.
