SPEEDBOXMINI / OverviewAndFeatures

Product Overview

The SPEEDBOX MINI is the second generation of GPS-Inertial speed measurement system from Race-Technology. The SPEEDBOX MINI combines data from GPS and inertial sensors to provide a full 200Hz speed update rate with outputs on RS232, CAN or digital pulse. The SPEEDBOX MINI includes a trigger input, CAN and serial ports. All inputs and outputs are configurable from the dedicated PC software supplied.

SPEEDBOX MINI Options

Several options are available to further extend the SPEEDBOX MINI:

 
The RTK option enables the SPEEDBOX MINI to provide high accuracy slip angle, pitch and yaw measurements at up to 20Hz.
 
 
The INS option combines the output from a 6 DoF IMU with the GPS solution to provide a full 200Hz solution of speed, heading, attitude (roll, pitch and yaw), slip angle and more.
 


Applications

The SPEEDBOX MINI is designed to be used as a sensor head either for direct connection to a PC or to an additional data logging system, primarily for OEM testing and high-end motorsport applications, or anywhere a high accuracy real time speed measurement is required. The SPEEDBOX MINI is also ideal for interactive testing in conjunction with the supplied Performance Monitor software.

Standard Features

The main feature of the SPEEDBOX MINI is the 200Hz high accuracy speed output derived from combined accelerometer and GPS speed data. Key features of the SPEEDBOX MINI include:

  • High accuracy 200Hz speed output.
  • 20Hz GPS speed and position output.
  • 3 Axis acceleration measurements.
  • Serial and USB ports (3 output modes)
  • CAN output port
  • Brake / event trigger input
  • Wide 9-15vsupply range
  • Extremely low latency (<4ms)
  • Low power (3w)

Pulse Output

The SPEEDBOX MINI has a digital pulse output with frequency proportional to combined speed (0-5v). Pulse timing characteristics are user-configurable to allow the SPEEDBOX MINI to act as a drop-in replacement for a wide range of ‘5th wheel’ devices. Alternatively, the pulse output can be configured to output a time pulse which is precisely synchronised to GPS time, the timepulse is output once per second, at a 50% duty cycle.

Trigger Input

A trigger input allows synchronisation of the SPEEDBOX MINI output with external events, such as pedal depression, or passing a marker point, such as a laser barrier. The trigger may be configured to either turn the outputs on/off or to send accurate time stamps on the serial or CAN port. The timing messages can be used in conjunction with the PC based timing software to give external trigger based timings for test start and end points.

CAN Output

The SPEEDBOX MINI CAN outputs can be set up for the Race Technology standard CAN output addresses, or can be configured for user defined addresses and rates. The Race Technology CAN database (.dbc) file is available for the standard configuration. Full CAN message details can be found on our knowledgebase.

Serial (RS232) / USB Output

One serial output and one USB port are available.

The serial port outputs messages in Race Technology’s own format, for easy viewing and analysis by our powerful supplied software. The SPEEDBOX MINI can also be connected to our data-logger and display products in order to log or view the data in this format. The serial output is also available in NMEA or uBlox format if preferred.

PC based measurement

In addition to using the SPEEDBOX MINI as a sensor head with a data logging system, the SPEEDBOX MINI can be connected directly to a PC for live data recording via serial or USB as well as real time performance measurements using the dedicated Performance Monitor software.
