CAR2CAR ADAS SYSTEM


Vehicle Speed and Distance Measurement System for the detection of distances in real time based on GPS between two vehicles with analog capture up to 5kHz, CAN bus, and up to 4 cameras

DualCar is a vehicle-to-vehicle measurement system to test and verify ADAS devices like:


  • Adaptive Cruise Control
  • Lane Departure and Collision Warning
  • Vehicle Collision Mitigation

The DualCar can be used also for non-contact, vehicle-to-vehicle speed and distance measurements.
The fully compatibility with the NaviControl Driverless Robot System offer the most power full testing solution for advanced technologies.



IMU assisted Dual-frequency GNSS receiver
The all-in-view dual-frequency GPS and GLONASS receiver, IMU assisted, is capable to generate an enhanced integrated position in shadowed environments with 50 Hz data output rate.

The RTK Base Station bring the position accuracy to ± 2 cm

IMU assisted Dual-frequency GNSS receiver
The inertial measurement unit (IMU) is used to estimate the vehicle orientation.
To compensate for drift completely, the IMU corrects its orientation every sample using the gravity and the earth magnetic field as reference vectors.

Addition information such as heading, pitch and roll are available as IMU outputs:

  • 3D Orientation (Euler angles)
  • 3D (free) acceleration, 3D rate of turn

Data Logging Capability
A powerful data acquisition system enhances the DualCar data logging capability.

The DualCar may be equipped with up to 64 analog inputs and 8 digital inputs.

A CAN bus interface is also available to obtain engine rpm and any other vehicle information.

DualCar Architecture
A Vehicle-to-Vehicle measurement layout is based on:

  • 2 Rover Units installed in both vehicles
  • 1 Ground Base Station (RTK generation)

For testing in public roads the RTK functionality can be implemented between the vehicles without using the Base Station.

Vehicle-to-Vehicle measurements
The position of the 2 Rover Units is measured and transmitted to each other. The Ground Base station broadcast to the 2 vehicles the RTK corrections, necessary to improve the 2 cm position accuracy.

The vehicles position and the RTK correction are transmitted by the same Wi-Fi link, no other radio link are required.

Vehicle-to-Vehicle measurements
The Ground Base and the Rover Units components can be quickly installed and removed from the vehicles.

When the Ground Base is not present one of the Rover Unit can generates the RTK correction.

The MOVING RTK mode allows to bring the relative position accuracy between the two vehicles in about 3 cm.

Software
All the information regarding: distance, speed, yaw angle, acceleration are displayed by graphical and numerical values.
The DualCar software allows an easily configuration of the main parameters.
Data logging triggers can be defined in type, slope, channel and value.
By simply uploading DBC files (Vector) the CAN Bus channels can be configured.
The driver can modify the display configuration by choosing between analog, digital or CAN channels.
Up to 16 channels can be represent continuously on the onboard monitor.
To help the driver for the external viewing, the on-board camera preview can be easily enlarged by clicking on it.

Analyzer Software
The DualCar Analyzer is a powerfull analysis software to post processing the acquired data.
The synchronized real time videos and the vehicles shape are displayed on the top and the selected acquired data on the bottom.
One or more acquired channels can be selected and displayed, and simply moving the cursor on the graph, all the parameters value will be updated.
Record and Playback capability are available.
The ASCII Export function allows to produce a full featured tabbed ASCII file.
