This work presents an approach to the condition monitoring in vehicle. A vibration test profiles is obtained in road testing of sedan size car. The first step is to define the performance parameters under study. The output depend variable are frequency, R.M.S, energy, and acceleration amplitude which have been considered for the measurement. Design parameter such as steering ,brake pedal, seat and engine are defined as those related directly to operational testing on specific test vehicle and which summarize the input to the vehicle in the given speed conditions. The overall objective of the research study was to analysis the vibration signature due to the mechanical problem in order to reduce the rate of the vibration. All the performance and operational characteristics of leading-edge of vibration technological were approaches to monitoring the vehicle systems.
