This Information Report relates to a special class of automotive adaptive equipment which consists of modifications to the power brake booster systems provided as original equipment of motor vehicles. These modifications are generically called "Reduced Effort Power Brakes" (REPB) The purpose of the modification is to lower the amount of driver effort required to apply the brakes. Retention of reliability, ease of use and maintainability for disabled drivers, passengers, and the general public is of primary concern. Reduced Effort Power Brake modifications should be qualified by the tests referenced in the Recommended Test Procedure. The tests set forth in that procedure should be applied, and failure of a Reduced Effort Power Brake modification to meet those tests should disqualify the modification from the claim of meeting the specifications of this Information Report.

This test procedure is for qualification testing of powered gas/brake control systems to assure compliance with the Recommended Practices for these assistive devices. A powered gas/brake control system which passes all of the tests shall be considered to be in compliance with the Recommended Practices. The control shall pass all tests denoted by a “shall” in the Recommended Practice or the Recommended Test Procedure. All the results of all tests and requirements denoted by a “should” shall be noted, but failure to comply will not constitute failure to pass the test.

A powered gas/brake control system which passes all of the tests shall be considered to be in compliance with the recommended practices. The control shall pass all tests denoted by a “shall” in the recommended practice or the recommended test procedure (RTP). All the results of all tests and requirements denoted by a “should” shall be noted, but failure to comply will not constitute failure to pass the test.

The terms included in this SAE Information Report have been collected during the development of SAE documents related to standards for the adaptation of vehicles for use by persons with physical disabilities. It includes only those terms that are pertinent to the adaptive devices discipline, leaving to other authorities more common automotive engineering terms. Where several terms have a common meaning in the practice, the Terminology Task Force has attempted to select the most appropriate term. The Terminology Task Force recognizes that there will be a need to expand and update current terminology as advances in the industry occur, and as related standards documents are completed. Accordingly, they will continue to develop and maintain this document to reflect those changes.

This SAE Recommended Practice establishes a uniform procedure for assuring the manufactured quality, installed utility, and performance of automotive powered gas/brake controls other than those provided by the vehicle manufacturer (OEM). These products are intended to provide driving capability to persons with physical disabilities. These products function as adaptive modifications to compensate for lost or reduced function in the extremities of the driver. Powered gas/brake control systems are not only designed to transfer foot functions to the hands or from one side of the body to the other, but to supplement by power, other than by the driver’s own muscular efforts, the force output of the driver.
