Power performance, economy and braking test system

Overview

Automobile power, fuel (gas, electricity) economy, and braking performance, also known in the industry as basic vehicle performance or fifth-wheel instrument, is one of the common test items for motor vehicles, suitable for traditional vehicles and new energy vehicles. The basic performance test system for power/economy/brake performance has two test equipment configuration schemes to choose from: (1) laptop + data collector scheme; (2) embedded all-in-one machine scheme.

Measurement parameters

Required parameters: vehicle speed, time, distance, fuel consumption, MFDD, pedal force
Selected measurement parameters: pedal displacement, brake line pressure, traction force, engine speed

Main features

Full Chinese operation: clear interface, high-contrast color matching
Meet national standards: suitable for China's automotive testing industry
High-precision speed measurement: FPGA-based hardware equal-precision speed measurement algorithm
Efficient data management: automatic classification management of test data, support for rapid test report generation
Convenient test operation: Fully consider the working conditions of vehicle vibration, one-button operation, support voice prompt function
