In this enlightening article we will be discussing the history of driving aids, angstrom well as some of the more common types and styles of hand controls available on the market today.

Devices that allow a disable individual to operate a motor vehicle without the consumption of their legs have been around for closely a hundred. Known as hand controls, these devices have evolved and come a long way since they were first gear think of. In the early 1900s, at-home inventors and tinkerers in their garages modified steering wheels to accommodate their residual limbs or prosthetics. They invented hand controls to operate early on cars with three pedals, without the use of their legs .
Decades late, after WWII, there was a spike heel in demand for driving aids, such as hand controls, to assist veterans trying to drive after having returned dwelling from the war with injuries or disabilities. Driving aids were researched and developed by automotive manufacturers, but by the 1960 ’ s demand had started to wane, and so inquiry and development of these types of products again fell to at-home inventors and tinkerers .
Fast forward another copulate of decades to the 1980 ’ sulfur, and, spurred by demand due to the massive inflow of Vietnam War veterans, research and development again came to forth to larger manufacturing companies. Since then, technology has advanced enormously, and although some of the styles and components of today ’ second hand controls may be alike to those first versions from the early on 1900 ’ south, these days handwriting controls can be promptly ordered from a reputable manufacturer, having been mass produced after passing muster in a baffle industry, and are available to assist people with assorted disabilities and can be installed in about all makes and models of vehicles .
now that we know a fiddling history about hand controls, let ’ s take an in-depth look at the diverse types and styles of hand controls .
Categories of Hand Controls
modern hand controls can be separated into two categories ; mechanical or electronic .
Mechanical Hand Controls
much like the earliest examples of hand controls, mechanical hand controls consist of a arrangement of metallic element linkages that connect an input device to the brake bicycle and boast pedal. These linkages are configured in a direction that allow an input from the driver ’ mho handwriting to be transmitted to the brake bicycle or gas pedal via mechanical gesture .
Electronic Hand Controls
In equitable the past few years a new character of hand manipulate, known as electronic hand controls, which utilizes more modern engineering, has emerged on the marketplace. In years past, on older vehicles, when a driver would step on the flatulence pedal, there was a steer link to the engine. This is known as “ fly-by-cable ”. The cable being the physical liaison between the gas pedal point and engine. As engineering advanced, cars have been equipped with what is known as “ fly-by-wire ” ; with the wire being an electric wire. In a fly-by-wire system, there is no physical, moving, connection between the gasoline bicycle and the engine. alternatively, there is a detector on the gasoline pedal which transmits an electric signal via the telegram to a mechanism on the engine, which tells it to accelerate, depending on the position of the gas pedal. electronic hand controls utilize these electric signals in the same way, the merely difference is the bespeak international relations and security network ’ thymine coming from the natural gas pedal point, it ’ south coming from a hand dominance. The leave is a reduction in the come of metal linkages and moving parts in the driver ’ s sphere. Since all that is needed to transmit the signal is a thin electric wire, there is no motivation for the metal linkage from the hand control to the boast bicycle. The linkage to the brake bicycle remains since braking system are still forcible, hydraulic systems that require the brake pedal be depressed .
nowadays that we have covered the types of hand controls, let us move on to the different styles of hand controls .
Hand Control Types & Styles
When talking about pass controls types and styles, we don ’ t mean how cool they look. When referring to a hand control type, we are referring to where the hand control is mounted in the vehicle : column Mount or Floor Mount. Column Mount hand controls normally consist of a horizontal hand control lever and mount on or near the steering column. Floor Mount hand controls, typically consist of a upright lever which is a like form to a transmission gearshift lever, mount to the shock and are operated near the right side of the driver ’ s buttocks. And when we say hired hand see dash, we are referring to the design of the hand controls and the motion involved with brake and accelerating while using them. Most of the styles of hired hand controls discussed here can be found as either mechanical or electronic. It is important to choose hand controls that best suit the exploiter ’ sulfur needs and that allows them safe, effective operation of the vehicle .
Column Mount Hand Controls
Column climb hand controls are the most normally used type. In most cases, they can be installed with no permanent modifications to the vehicle. Since the hand operate lever is mounted to the steering column, the driver ’ sulfur hands are never excessively far from the steering wheel. When the fomite is being used by early drivers, an accelerator lock-out feature of speech ( available on most styles of hand control ) can be activated to prevent unintended hand master acceleration .
When using a Push/Right Angle hired hand controls, the drug user will “ Push ” the hand control forward to brake. To accelerate, the user would push the handwriting control down ( called “ Right angle ” because when they push down to accelerate it is at a 90 academic degree angle from pushing the tied advancing to brake. besides known as a Right Angle ) .

The Push/Pull style of hand controls operates just like it sounds. The exploiter would “ Push ” the hand control lever to brake, and “ Pull ” the hand control lever to accelerate .
The Push/Rock expressive style of hand controls make habit of an good manage at the end of the horizontal lever. The exploiter would “ Push ” the hand control lever to brake, and “ Rock ” the upright handle back and down toward the driver to accelerate .
Floor Mount Hand Controls
Floor mount hand controls are less normally used, however, there are certain applications where a drug user is more comfortable, or a floor mounted hand operate system is more virtual. barely as with column hop on hand controls, floor backing hired hand controls can normally be installed with no permanent modifications made to the vehicle. Floor mounted pass controls are normally installed to the right of the driver ’ s seat, between the seat and the center comfort area. A vertical pry with a treat, similar to a transmission sceneshifter, is used for remark. These systems typically take up less space in the peg area .
Push/Twist Hand Controls
With a Push/Twist dash hand control system, the driver would “ Push ” the pry forward to brake, and “ Twist ” the treat of the lever to accelerate. This style of floor mounted handwriting operate allows for those with less range of motion in their arm to operate the vehicle .
Push/Pull Hand Controls (Floor Mount)
The Push/Pull style of hand controls operates barely as the name implies. The drug user would “ Push ” the vertical hand see lever ahead to brake, and “ Pull ” the vertical hired hand control lever back to accelerate .
