(R) Recommended Practice for Powered Gas Brake Control Systems
|Publication Date:||1 October 2007|
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.
This document is applicable to mechanical and electrical products intended by the manufacturer to meet the following criteria.
Operated by a vehicle driver with a physical disability.
Substitutes for the use of OEM vehicle accelerator and brake pedals, yet retains the OEM pedals for use by nondisabled drivers.
Output of the powered gas/brake device is applied to the OEM brake and gas assembly in order to change the force or range of motion required of the disabled driver.
All sections of this document are applicable to Group A primary controls.
This document is not applicable to any automotive adaptive product which:
Is applied to vehicles without powered brakes unless it is specifically designed for that application and clearly states that in its product literature.
Modifies the force and range of motion needed for operating a control by simple changes of leverage (such as manual driver controls).
Is considered to be Group B primary controls or secondary controls.
Is intended as a special control for driver evaluation, training, or research.
The purpose of this document is to provide criteria to evaluate powered gas/brake control system design, manufacture, installation, operation, maintenance and performance. Methods to measure those criteria are included in the accompanying Recommended Test Procedure (SAE J2604).
