Description / Abstract:
This SAE Recommended Practice establishes a uniform procedure
for assuring the manufactured quality, installed utility and
performance of automotive products to the relocation, alteration,
replacement and/or extension of secondary controls and systems
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. These include, but are not limited to
the following:
Cruise Control; Door Locks; Gear Selector; Hazard Flasher;
Headlight Beam Selector; Heater/Vent/Air Conditioner (HVAC); Horn;
Ignition/Starter; Light controls; Mirrors; Parking Brake; Power
Seats; Turn Signals; Power Window Controls; and Windshield
Wiper/Washer and defogger; Rear Accessories (Defogger,
Wiper/Washer).
The purpose of any secondary control adaptation is to provide
the effective use of the motor vehicle operating systems to a
driver with a disability, so that he or she may drive and operate
that motor vehicle with the same degree of safety as a non-disabled
driver. Thus, the adaptive equipment must be (1) accessible to the
driver with a disability for whom it is designed, (2) not
susceptible to inadvertent operation which may be inconvenient or
dangerous for the driver and other users of the roadway, and (3)
suitable by non-disabled drivers who may have a need to operate the
motor vehicle whenever possible.
For purpose of this document, the secondary controls listed
previously have been classified according to the following
protocols. The categorization of these controls, while different
from other SAE publications, is reflective of the manner in which
driver rehabilitation specialists determine appropriate vehicle
modifications. These categories are arranged to assign priorities
that allow the user to operate a vehicle in the most efficient
manner possible.
Mode A - These controls shall be operable by the driver while
the vehicle is in operating mode. They must be accessible to the
driver for which they were intended while being able to maintain
control of the vehicle steering, brake and accelerator functions.
Included in this group are: Cruise control "Set;" Headlight Beam
Selector; Horn; Turn Signals; and, Windshield Washer/Momentary
Wipe.
Mode B - These controls shall be operable by the driver while
maintaining control of the vehicle brake function with the vehicle
not in motion, as in the case of vehicle start-up or re-start
necessitated by engine stall. Included in this group are: Gear
Selector and Ignition/Starter.
Mode C - These controls shall be at least operable by the driver
when the vehicle is stationary, either temporarily or parked.
Included in this group are: Cruise control "On" and "Off;" Door
Locks; Hazard Flashers; Heater/Vent/Air Conditioner (HVAC); Light
Controls; Mirrors; Parking Brake; Power Seats; Windshield Wiper;
and Power Window Controls; Rear Accessories (Defogger,
Wiper/Washer).
