The VBOX Audio Sensor captures audible warnings such as those given during Forward Collision Warning (FCW), Driver Status Monitoring (DSM) and Dooring scenarios. It can also be used to detect information functions such as Occupant Status Monitoring (OSM), Seat Belt Reminder (SBR) and Signpost Recognition (SPR).

The sensor has custom-built software that makes it user-configurable to react to any audible notification by a vehicle under test.

You can configure thresholds to detect the required frequency over environmental noises from the test vehicle, such as road and car noise.

This unit differs from similar sensors by being configurable to detect high-frequency Haptic warnings by using the audible tone of the created vibration. The unit will capture these warnings and output the data to either a VBOX for an immediate pass/fail result based on the scenario OR directly into a driving robot for a live reaction to a warning.

The VBOX Audio Sensor is designed to work alongside, or independent of, the other sensors in the VBOX ADAS Sensor Pack. It is just one of an array of warning detection methods produced by Racelogic to fulfil requirements set by regulatory and consumer groups, including UNECE and Euro NCAP, and in research and development activities.

Features

Triggered by an audible warning or information function given by the test vehicle.
Can differentiate between exterior environmental noise and a required frequency.
User-configurable to trigger multiple frequencies sequentially.
User-configurable to trigger off ‘ALL’ or ‘ANY’ frequency in multi-frequency tones.
Its built-in microphone is suitable for most applications, but an additional external ‘plug-in’ microphone is included for high-noise environments or concealed speaker units.

Has the ability to delay digital outputs to a fixed delay after the START of the sound.
Integrated LEDs for clear ON/OFF confirmation when a sound has been sensed/triggered.
Immediate CAN output contains Time Since Audio Start as part of its message.
Digital output (0 to 5 V / open drain compatible).
5 mm internal thread to ensure rigid mounting in the vehicle.
