On-vehicle coastdown road load test system

Overview

The on-vehicle coastdown road load test system supports SAE J2263-2020 and the road-load coastdown method in Annex CC of Limits and Measurement Methods for Emissions from Light-duty Vehicles (China 6). It combines data acquisition and analysis.

Features

An integrated high-accuracy imported weather sensor measures wind direction, wind speed, atmospheric pressure and temperature, with quick installation and performance meeting domestic and international standards.
Step-by-step data collection and one-click analysis without manual file management.
A clear interface with synchronised dynamic charts.
Segmented coastdown reduces track requirements.
Results in metric and imperial units.
One-click test reports with customisable PDF and DOC output.
Sensor calibration.
Built-in charts for reviewing raw data.
A reference data-quality score after each coastdown.
