Description / Abstract:
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.
Inclusions
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.
Exclusions
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.
Purpose
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).
