Analogue input module

Modules

The range of VBOX input and output modules allows for data capture from test vehicles and increases the functionality of our data loggers. Analogue, frequency, CAN, and thermocouple signals are integrated into GPS data and a combination of module channels can be recorded simultaneously. Our Inertial Measurement module outputs pitch/roll and yaw data as well as providing a smoothed GPS velocity signal when used in unfavourable conditions.

Racelogic Basestation

Basestations

The RACELOGIC DGNSS Base Station is designed to improve positional accuracy of VBOXes and other compatible GPS/ GLONASS systems by calculating and transmitting differential correction data. By programming the Base Station with a known position, it is able to accurately monitor the difference between its programmed position and the position that it is receiving via GPS/GLONASS. The difference is then transmitted via radio to allow a remote GPS system to correct its position. The differential correction message can be broadcasted in RTCM, CMR or proprietary RTK formats using an internal or mast mounted radio modem transmitter. Depending on the type of Base Station and roving unit used, position accuracies of up to 2cm 95% CEP are available.

Multifunction Display

Displays

VBOX displays offer a variety of real time results feedback and unit setup. The advantage of using a display is the speed and convenience of altering test parameters or verifying data during the procedures themselves; sometimes the ability to abort a run, often only possible when in-vehicle viewing of data is available, can greatly reduce the amount of track time required.

VBOX displays range from full tablet PC, to LCD multifunction, to speed and lap timing units.

Brake Pedal Trigger

Brake Pedal Trigger

Precise measurement of brake pedal application during VBOX brake stop tests The trigger completes a circuit which pulls a floating 5V output to ground when pressed, with the exact time this event occurred being captured and recorded by the VBOX at a high sampled frequency. The frequency at which the trigger event is recorded is dependent on the model of VBOX in use. The brake trigger event time capture is stored in internal memory and stamped into the VBO file to interpolate the speed between GPS samples which is the key component for a high accuracy brake stop distance calculation.

Brake Trigger interface

Brake Trigger Interface

Conduct brake tests without a brake pedal trigger With the Racelogic brake trigger interface module it is possible to conduct brake stop tests without employing a traditional brake pedal trigger. This is ideal if the vehicle is already installed with a brake pressure sensor and cannot therefore also use a brake pedal trigger. The interface is connected to the vehicle’s high 12V brake light system, and when the brakes are applied, converts it into an active low 0V signal which acts as a trigger event for the VBOX. Connection to the VBOX is via Lemo

 

Hand Held Brake trigger

Start/Stop Logging Switch

Rugged and lightweight switch used for starting and stopping the data logging The switch is a latching push switch that, when in the open position, starts the data logging and when in the closed position stops the data logging. The latching feature eliminates the need for constant pressure to be applied to the switch, ensuring that the driver of the vehicle can keep two hands on the steering wheel.

Racelogic Light Barrier

Light Barrier Kit

Consistent logging of event marking and triggers The Racelogic Light Barrier kit (RLVBACS063) comprises of an optical sensor with power and trigger output connections, a Culman suction mount with a metal mounting plate for the optical sensor and a square plastic reflector plate. The trigger cable from the light barrier unit connects directly with the trigger input of a VBOX and the power cable can connect to any of the 5 way lemo connectors on a VBOX to pickup power. The kit is often employed in drive-by noise tests where volume output must be measured at exactly the same point in every instance

Laser light barrier

Laser Light Barrier Kit

Consistent logging of event marking and triggers. The Racelogic Laser Light Barrier kit (RLACS189) comprises of an optical sensor with power and trigger output connections, a Bohle suction mount with a metal mounting plate for the optical sensor and 2m of reflective tape.

Antenna

GPS Antennas

Racelogic provide a number of different antenna options, depending upon the measurement system, the type of vehicle being used and the surrounding conditions. Standard magnetic “patch” antennas are suitable where they have an unrestricted view of the sky and a good metallic ground plane, such as a car roof. However, the quality of the signal received can be reduced by reflections from surrounding buildings, trees, and other obstructions. This is known as multipath and can result in increased noise and reduced accuracy.

Effects of noisy GPS signals
  • Less accurate general performance results. If the vehicle test is using speed as a start or end condition then the test could be started or stopped at the wrong time, leading to incorrect results
  • Less accurate Lateral and Longitudinal acceleration data
  • Less accurate Radius Of Turn and Centre Line Deviation tests
  • Less accurate slip angle tests
  • Less accurate vehicle position / driveline
CAN Splitter Box

CAN Splitter Boxes

The RLVBACS024 allows more than one 5-Way Lemo connection to be made to one 5-Way Lemo socket on a VBOX. This is most commonly used to allow an RS232 and a CAN connection to be made into the same socket. The RLVBACS024/1 additionally has a Simplex RS232 socket for PC connection in vehicle separation tests.

RLVBACS027_Digital-input-splitter (1)

Digital Input Splitter Box

The RLVBACS027 enables more than one brake trigger to be used with a VBOX, or a brake trigger along with a start/stop logging switch.

Clip On CAN

Clip-on CAN Interface

Tap into the CAN Bus without a physical connection.

The RLACS182 provides a quick and convenient way of tapping onto a CAN Bus when recording vehicle signals.
Available with either Mini-Din or Lemo connectors, the RLACS182 is suitable for use with most Racelogic systems.

USB To serial converter
