Scope This SAE Information Report establishes a uniform procedure for assuring the manufactured quality, installed util

5、ity and performance of automotive remote steering controls other than those provided by the vehicle manufacturer (OEM). These products are intended to provide driving capability to persons with physical disabilities. The adaptive modifications seek to compensate for lost or reduced function in the e

6、xtremities of the driver with a disability. Remote steering controls are designed to provide a steering input device alternative to the OEM steering wheel that either reduces the required input force, changes the required range of motion or changes the location of the steering control or any combina

7、tion of the above. These controls supplement by power, other than by the drivers own muscular efforts, the force output of the driver with a disability. Because this is an Information Report, the numerical values for performance measurements presented in this report and in the accompanying Test Proc

8、edure, while based upon the best knowledge available at the time, have not been validated by a testing of the Test Procedure. 1.1 Inclusions This document is specifically concerned with mechanical and electrical products intended by the manufacturer to meet the following criteria. 1.1.1 Is operated

9、by a vehicle driver with a physical disability. 1.1.2 Substitutes for the use of the OEM steering wheel. 1.1.3 Output of the remote steering device is applied to the OEM steering system in order to change the force or range of motion or ability to reach the steering control required of the driver wi

10、th a disability. 1.2 Exclusions This document specifically excludes any automotive adaptive product which: 1.2.1 Is applied to vehicles without powered steering unless it is specifically designed for that application and clearly states that in its product literature. SAE J2588 Issued AUG2004 - 2 - 1

11、.2.2 Modifies the OEM steering effort control system as identified in J 2672 (Reduced Effort Steering document). 1.2.3 Is considered to be Group B Control or Secondary Control. 1.2.4 Is intended as a special control for driver evaluation, training, or research. 1.3 Purpose The purpose of this docume

12、nt is to provide criteria to evaluate remote steering control system design, manufacture, installation, operation, maintenance and performance. Methods to measure those criteria are included in the Recommended Test Procedures (RTP) attached as an Appendix to this Information Report. 2. References 2.

37、lure. 3.21 Response Time The elapsed time between initiation of a step input to the control input mechanism until the time when the output reaches 63% of the output associated with the selected level of steady-state input. 3.22 Servo A power device, which amplifies control forces and automatically c

38、orrects the output in proportion to input. (SAE J2094) 3.23 Shall The term to be used whenever the criteria for conformance with the specific recommendations requires that there be no deviation. (SAE J1159) (Note: Because this is an Information Report which makes recommendations, but is not standard

39、s, the use of the word shall has been replaced by should elsewhere in the report.) 3.24 Should The term to be used whenever non-compliance with the specific recommendation is permissible. (SAE J1159) 3.25 Steering End-Stop The mechanical limit of rotation of the OEM steering shaft in either directio

40、n as determined by the OEM power steering pump bypass function. 3.26 Step Input An input into a control system in which the input is made at one time, rather than as a gradual increase or an increase following a specific mathematical function. 3.27 Unidirectional Revolving, functioning, moving, or r

41、esponsive in a single direction. (SAE J1903) 3.28 Visible Deformation A change in alignment, position, or shape that is apparent to a careful observer. (SAE J1903) SAE J2588 Issued AUG2004 - 7 - 4. Performance Requirements and Manufacturing Quality 4.1 Remote Steering Control Performance The remote

42、steering control should not degrade the performance attainable with the OEM unmodified steering system except as noted in this Information Report. Failure of the remote steering control system to attain the performance characteristics attainable with the (OEM) power steering system using input force

43、s on the control input mechanism, specified by the control manufacturer, should be unacceptable. (APPENDIX - RTP 4.1.6.1 and 4.1.6.2) 4.1.1 FORCE AND TRAVEL INPUT The control manufacturer should specify the minimum input force required to operate the control input mechanism, the location on the cont

44、rol input mechanism where the force is to be applied, and the corresponding travel of the control input mechanism in relation to that point, by incorporating them into their user manual or product literature. These force and travel input specifications are to be the maximum force and travel of the s

45、teering control system and are intended to provide information to users about the system characteristics. The manufacturer should also specify the steering control output, which should result from those inputs. (APPENDIX - RTP 2.6, APPENDIX - RTP 4.1) 4.1.2 TORQUE OUTPUT The output of the remote ste

46、ering control system should be capable of steering the vehicle at any speed for 5 min with the OEM power steering failed in the vehicle specified by the manufacturer as suitable for installation of the remote steering control system. (APPENDIX - RTP 4.1.2) Rationale: These requirements are designed

47、to ensure that the remote steering control system does not degrade the steering performance of the OEM steering system, regardless of any changes made. 4.1.3 CONTROL PREDICTABILITY The output of the remote steering control system as applied to the OEM components should bear a repeatable relationship

48、 to the inputs. 4.1.3.1 Repeatability A given input to the remote steering control should cause a repeatable corresponding output to the OEM system. (APPENDIX - RTP 4.2.5) Rationale: This is to insure that the control system does not present any variables in operation, causing the operator to have t

49、o search for the correct position of the control mechanism for the desired response each time the control is operated. 4.1.3.2 The remote steering control system initial response time for steering should not exceed 0.1 second. (APPENDIX - RTP 4.2.6.) 4.1.3.3 Lag or delay in response of the control output to driver input is inherent in any powered control system, however, lag should not be sufficient to degrade performance in an offset lane test. (APPENDIX - RTP 4.1.6.1) SAE J2588 Issued AUG2004 - 8 - 4.1.3.4 Lag or delay in response of the control output
