Along with the Regular tests on Dynamometer (Max Speed, Max Power, Acceleration etc); this Dyno offers additional features of ABS (Antilock Brake System) Integration. This Dyno is of Multi-motor Configuration.

Following are the different Braking Techniques to be tested:

  • Threshold braking
  • Locked wheels
  • ABS (Antilock Brake System)
  • Cadence braking

About VSCADA Software

Goto Top

The purpose of this software is to define various test modes, to test the performance of the vehicle on the road (in simulated condition on Chassis Dynamometer). This software is mainly used to evaluate the various performance parameters like:

  • Vehicle Power in Wide-open Throttle (WOT) Condition
  • Fuel Consumption at various speeds under Road Load Condition
  • Maximum Speed, Acceleration by Speed (Time), Acceleration by Distance
  • Performance of Vehicle under Indian Drive Cycle (IDC)
  • Emission parameter calculations under various legislative driving cycles
  • Designed measurement and control system meet the requirement of the EPA and ECE guidelines

User Configurable Modes of VSCADA:

  • Warm Up Mode
  • Dyno Calibration Mode
  • Vehicle Calibration Mode
  • RLS Mode
  • RLS Coast Down
  • Calibration Mode
  • Speed Control Mode

Reports and Graphs from VSCADA:

  • Individual mode based reporting
  • Mode specific report format
  • Powerful data management system
  • Conversion of data into CSV format
