What is VMU (Vehicle Monitoring Unit)?
VMU is experimental vehicle monitoring equipment.
VMU is a device such as measuring to record REAL-TIME information related to power train (engine/transmission), embedded various kind of vehicle sensors (temperature/ voltage/ longitudinal/ vertical acceleration/ ATC, etc.) , vehicle location and vehicle performance.
It can be linked with PC, PDAs using VMU Software Tools.
Measured data are made practical application of precise analysis supported by getting graphic and tabular formats displayed.

Specialized monitoring for vehicle engine and transmission
Successful setup of various measuring mode in new engine/transmission development
Suitable for long term specialized monitoring for multi vehicles
Real time monitoring, surveillance, and management via web are available in remote site operating vehicles.
Easy configuration of inspection condition for auto clients
Suitable for configuration of actual inspection even for non-specialist drivers.
The driver doesn`t need to press the button whenever the engine ignition turned on / off because the VMU automatically detects when the engine is started. It will also start detecting and store all data collected from the vehicle.
Collection of variety of external sensor data and GPS reception
Suitable for collecting temperature, voltage, Digital & Analog signal, and Pulse Signal data
A realization and comparative analysis of engine/transmission monitoring data and the same time axle data is available.
Vehicle tracking solution is available as well when combined with GPS/GSM |
