降低手控力的助力转向和助力转向备用系统

[中文适用范围]： 本信息报告涉及一类特殊的汽车自适应设备，其中包括对原始设备制造商 (OEM) 动力转向系统的液压控制机构的修改，这些系统作为个人许可车辆上的原始设备提供。这些修改通常被称为“省力动力转向”。修改的目的是降低驾驶员操作转向系统所需的力气。保持可靠性、残疾驾驶员的易用性和可维护性是首要考虑的问题。由于这是一份信息报告，因此本报告和随附测试程序中提供的性能测量数值虽然基于当时可用的最佳知识，但尚未通过测试程序测试进行验证。 [外文原描述]： This SAE Information Report relates to a special class of automotive adaptive equipment which consists of modifications to the power steering system provided as original equipment on personally licensed vehicles. These modifications are generically called “modified effort steering” or “reduced effort power steering.” The purpose of the modification is to alter the amount of driver effort required to steer the vehicle. Retention of reliability, ease of use for physically disabled drivers and maintainability are of primary concern. As an Information Report, the numerical values for performance measurements presented in this report and in the test procedure in the appendices, while based upon the best knowledge available at the time, have not been validated.
