BUSINESS FUNCTION - VEHICLE BASIC CHARACTERISTIC MEASUREMENT CONTRACT TEST OVERVIEW

Vehicle basic characteristic
measurement Contract test overview

Since delivering its first machine in 1980, Automax has been the only manufacturer in Japan of basic vehicle characteristic measurement systems that statically measure suspension and steering parameters on a bench.

Starting in 2021, we have decided to install this proven system at our factory and conduct contract test.

The test involves inputting the load or displacement from the tire contact surface with the vehicle fixed, and measuring changes in wheel alignment and the load and moment on the tire contact surface.

Features and advantages of Automax

・The only one in Japan
・Accurate reproduction of alignment changes with zero-load servo control
・Low crosstalk load measurement that enables zero-load servo control
・Adopts the latest electric actuator
・Measurement data can be read in CarSim

Provided data

・Dataset for CarSim .par file
・Measurement data for each test
