The Vehicle Inertia Monitor (VIM) is a new dual mode advanced J1939 CAN-bus vibration analyzer and vehicle attitude sensor for heavy duty vehicle prognostics and performance monitoring.
The VIM vibration mode helps maintenance engineers plot equipment performance over time to characterize normal operating metrics. It captures and highlights subtle changes in vibration through use of high resolution sub-Hz analysis via multi-rate signal processing. This provides indicators pointing towards degradation in equipment performance. Subsequently, preventive maintenance can be performed to improve efficiency and avoid system failure replacement costs.
In addition to vehicle and engine maintenance prognostics, common VIM applications include road grade and pitch profiling; brake life estimation; gearbox vibration monitoring; and fleet management analytics.
