The new method of initial calibration with the wheel force transducer
Abstract
Purpose
One of the major shortcomings in the data process of the traditional wheel force transducers (WFTs) is the theoretical errors of initial value determination. A new method to identify the initial values of the WFT for the solution of this problem is proposed in this paper. The paper aims to discuss these issues.
Design/methodology/approach
With this method, the initial values can be obtained by equations which are established based on multiple stops on horizontal road.
Findings
The calibration and contrast tests on the MTS calibration platform illustrate the better performance with the new method. Moreover, the real vehicle test confirms the effectiveness in practice.
Originality/value
The test results show that the new method of initial calibration has an advanced performance compared to the traditional one. In addition, it is effective in the brake test with a real vehicle.
