Abstract: The automotive steering device is a key device for drivers to achieve their driving intentions. In order to further improve the accuracy of automotive steering device testing work, this article introduces the steering device testing methods for automotives in chapter six of the European Standard Uniform Provisions on the Approval of Vehicles in Terms of Steering Devices (UN Regulation No.79/03), and compares the similarities and differences between the analytical standards of the national standard GB 17675－2021. According to the test method of the European standard, an uncertainty analysis of steering control force is conducted on a certain N2 class truck as an example, and directions for improving the accuracy of the test are proposed through analysis.
