Scope: GB 11557-2011 Requirements for Preventing Injuries to Drivers Caused by Automotive Steering Mechanisms GB/T 17675-2021 Basic Requirements for Automotive Steering Systems GB 34660-2017 Electromagnetic Compatibility Requirements and Test Methods for Road Vehicles GB/T 35360 Terms and Definitions for Automotive Steering Systems QC/T 649-2013 Performance Requirements and Test Methods for Automotive Steering Control Mechanisms QC/T 1081-2017 Electric Power Steering Devices for Automobiles Main Technical Content: 1. Basic Performance Requirements This document sets detailed requirements for load-free oscillation and sensor characteristics. Compared with traditional mechanical C-EPS systems, the electronic steering road feel simulator removes the intermediate shaft, introducing new designs and mechanisms to the entire system, resulting in differences in all parameters. The addition of more mechanisms inevitably requires enhancing and improving the performance testing based on the original requirements and methods. At the same time, special attention is paid to testing and requiring load-free oscillation and sensor characteristics to ensure the performance, efficiency, and steering response of the overall product. 2. Strength Requirements On the basis of conventional strength requirements, additional requirements are set for the strength of the limit mechanism. Existing C-EPS systems do not have this mechanism; the limit function is achieved through the hard connection of the intermediate shaft and the steering gear. After withstanding impacts or high-intensity torque, the relevant performance parameters must still meet standard requirements. Due to the compact design of the worm-gear transmission mechanism, the strength of the limit mechanism needs to be verified and validated. 3. Durability Requirements The durability requirements are similar to existing ones, but for the electronic steering road feel simulator, additional requirements are
