Car conversion (steering, accelerator, brakes, shifting by hand and foot): Conversion for handicapped accessible cars

The manual operation of vehicles is a pioneering solution to enable people with mobility impairments to enjoy an independent driving experience. By redesigning conventional vehicle controls, individual needs can be taken into account and access to mobility expanded. We take a close look at the different facets of hand controls and how these conversions make driving more accessible for people with disabilities.

For many people with physical disabilities, the conventional operation of the accelerator pedal, brakes, steering wheel and gearshift is a challenge. Hand control offers an alternative control method in which these elements are redesigned so that they can be operated comfortably and safely with the hands. This not only enables mobility, but also increases the independence and quality of life of those affected.

Manual control components:

1. Steering wheel operation:
   • Conversion: A power steering handle enables the steering wheel to be turned with minimal effort. Some models also offer electric steering assistance.
2. Accelerator and brake pedal:
   • Conversion: Hand throttle and hand brake systems replace the conventional pedals and allow operation by hand.
3. Shift lever:
   • Conversion: Automatic transmissions or special manual controls for manual transmissions are installed to enable manual shifting.

Various systems for manual operation:

1. Mechanical manual operation:
   • Functionality: Direct mechanical connection between the hand controls and the original pedals or shift levers.
   • Advantages: Reliable, cost-effective, easy maintenance.
2. Electronic hand control:
   • How it works: Electronic systems convert hand movements into control commands.
   • Advantages: Precise control, customizable settings, state-of-the-art technology.

The manual operation of vehicles plays a crucial role in promoting the mobility of people with reduced mobility and giving them the opportunity to participate in road traffic and lead an independent life.

The "Classic" and "Compact" hand controls for brake and accelerator from the manufacturer Veigel have similar operating features to the HB-4300 and HB-4000 models. In addition, these products can be equipped with elegant additional control units, known as "Veigel-Commander", for controlling important secondary functions.

Installing the parking brake

FB-1000

Many modern vehicles are already fitted with an electric parking brake at the factory. However, due to disabilities, the original switch is often difficult to operate or is mounted in the 'wrong' place. This can be remedied by adapting, relocating or installing an additional switch. In the case of conventional mechanical parking brakes, an individual adaptation of the hand lever often makes them easier to operate.

The outstanding benefit of throttle ring systems is that, unlike hand-held control units with steering wheel rotary knobs, one hand always remains free. In all our throttle rings, the brake lever can be positioned either behind the steering wheel or on the center tunnel.

HB-5000

The throttle ring is mounted either on or under the steering wheel. The throttle can therefore be operated without releasing the steering wheel, regardless of the position of the hand on the steering wheel. The function of your airbag remains unaffected. With the rings mounted under the steering wheel, the throttle position can be determined both by pulling and pushing the ring. The throttle ring is usually combined with a mechanical hand control for the right-hand brake, but alternatives are of course also possible

The KS Wireless has been approved and released by the Italian Ministry of Transport, has CE marking and has successfully passed all EMC tests. The product is guaranteed for 5 years from the date of invoice.

Hand throttle systems enable people with amputations, paraplegia or reduced leg strength to drive their vehicle independently by operating the accelerator and brake by hand. For people with disabilities who wish to drive their car themselves, fitting a hand throttle system, also known as a hand control, offers greater independence and flexibility. This article looks at the different options, costs and finance options for hand throttle conversions to help you make your decision.

Hand control: How the hand throttle and hand brake work

As a person with no or limited leg function who wants to drive a car themselves, it is important to find out about hand throttle systems in detail. These systems make it possible to control the accelerator and brake safely and comfortably by hand. There are two main types of hand throttle systems: mechanical and electronic. Below you will find a detailed description of these systems and factors to consider when making your choice.

Mechanical hand throttle systems

Mechanical hand throttle systems are based on a direct mechanical connection between the hand control unit and the accelerator and brake pedals. Just like electronic hand throttle systems, they can function according to two different principles:

• Push-pull principle: Here, the accelerator pedal is actuated by a pulling movement, while the brake pedal is actuated by forward pressure. These systems are generally easy to operate and reliable.
• Turn-and-push principle: With this principle, the accelerator pedal is operated by a twisting movement, while the brake pedal is operated by pushing forward. These systems require a little more sensitivity, but offer greater control over the vehicle.

Mechanical hand throttle systems are generally less expensive than electronic systems, but offer less flexibility in terms of customization and installation on different vehicle models.

Electronic hand throttle systems

Electronic hand throttle systems are based on electrical signals that are sent to the accelerator and brake pedals by a hand control unit. As a result, they offer greater flexibility in terms of adjustment and can be equipped with additional functions such as indicators, horn, lights or windshield wipers. Electronic hand throttle systems are generally more expensive than mechanical systems, but offer greater comfort and safety.

Vehicle adaptations and combinations with hand throttle

To make a car safe and comfortable to use for people with limited leg function, hand throttle systems can be combined with various vehicle adaptations.

Pedal locks and pedal extensions

A pedal lock or pedal cover prevents unintentional operation of the pedals. This is often installed in addition to the hand throttle, as it increases safety and is usually prescribed by a technical inspection authority. Pedal extensions are used to make the pedals easier to reach for people with short legs.

Steering aids and steering wheel knob

Steering aids such as steering wheel knobs make steering easier for people who can only use one hand for steering. This is the case when using a hand throttle, which is why a steering wheel rotary knob or multifunction rotary knob is usually installed in addition to the hand throttle. In addition to precise control of the vehicle, the latter also enables secondary functions such as lights and indicators to be operated without letting go of the steering wheel.

Selecting a suitable hand throttle system for your car

Choosing the right hand throttle system for your vehicle is crucial to ensure a comfortable and safe driving experience. Consider your individual needs and capabilities and find out about available suppliers and manufacturers to find the best solution for your situation.

However, when looking for a suitable used vehicle with hand throttle, there are some important points to consider to ensure that you purchase a reliable and functional vehicle.

• Status of the hand throttle system: Make sure that the hand throttle system in the used vehicle is in perfect condition and functions properly. Test the system extensively during a test drive to ensure that it meets your requirements and has no defects. It is advisable to have the vehicle checked by a specialist workshop to uncover any hidden problems.
• Origin of the hand throttle system: Find out about the manufacturer and model of the hand throttle system in the used car. Make sure it is a reputable company that offers high-quality products. This not only guarantees better performance, but also easier maintenance and spare parts procurement in the event of repairs.
• Vehicle documentation and maintenance history: Check the vehicle documentation and the maintenance history to ensure that both the vehicle and the hand throttle system have been properly serviced and maintained. If necessary, have this confirmed by the specialist workshop. This can help you avoid potential problems or expensive repairs in the future.
• Customization and compatibility: Make sure that the used vehicle with hand throttle has all the necessary adaptations for your individual requirements or that it is possible to make further adaptations.
• Warranty and customer service: Ask about a warranty or guarantee for the hand throttle system and the vehicle itself. A warranty can offer you additional security and protect you from unexpected repair costs. Also make sure that the dealer or seller offers good customer service and is available to help with any problems or questions you may have.

Overall, buying a used car with hand throttle is an option that requires careful research and inspection. Make sure that the hand throttle system is in good condition, from a reputable manufacturer and that all necessary adjustments are present or can be made. A thorough inspection and test drive are essential to ensure you are purchasing a reliable and suitable vehicle.

Training and adaptation phase for cars with hand throttle

Before you start driving with the new hand throttle system, you should receive sufficient training to ensure that you can operate the system correctly. It may take some time to get used to the hand throttle, so allow for an appropriate adjustment period.

Maintenance and repair of hand-held gas systems

Regular maintenance and repair of your hand throttle system is crucial to ensure the longevity and safety of your disabled car. Hand throttle systems, whether a mechanical or electronic hand throttle, require professional maintenance to function optimally. Contact the supplier or manufacturer of your hand throttle system or a qualified specialist vehicle conversion company to ensure that your hand throttle car is regularly checked and maintained. Make sure that all components, including mechanics and electronics, are working properly and show no signs of wear. This will allow you to identify potential problems early and have them repaired before they lead to costly or dangerous situations. Invest in the maintenance of your wheelchair-accessible vehicle so that you can always travel safely and comfortably.

Costs and financing options for hand throttle conversions and disabled-accessible vehicles

The cost of a hand throttle system varies depending on the type, manufacturer and vehicle model. As a rule, the cost of a mechanical hand throttle conversion is between €2,000 and €5,000, while electronic systems can cost between €5,000 and €7,000. Added to this are the costs for any additional vehicle adaptations, such as pedal locks or steering aids, which may be necessary depending on individual requirements.

Mechanical left-hand throttle

The function of the accelerator pedal is transferred to a second, left-sided accelerator pedal. The original pedal is covered with a prosthetic support.
The device can be easily removed and refitted without tools.

Pedal covers

Pedal covers are important safety elements that reliably prevent unintentional operation of the pedals.
The pedal covers can be removed in seconds without tools.

Pedal raiser SHORT

Pedal attachments shorten the distance to the pedals by 50-100 mm. They are individually adjustable and can be removed in seconds without tools.

Pedal raiser MAXI

Enables an extension of 10-30 cm. The length, height and desired distance between the pedals can be set individually. Installation with quick release for easy removal is possible. Can be installed in vehicles with automatic and manual transmissions.

Gas left pluggable

For many cars, it is possible to move the accelerator pedal to the left by building a plug-in device. There is an optional holder for the prosthetic foot, which can be seen in the top left-hand picture. It prevents the prosthesis from obstructing the brake by getting onto the brake or getting wedged under it. If the car is used with right-hand throttle, the pedal can be quickly and easily moved to the other side.

Gas left standing

For people with right-sided leg impairments, it is possible to move the accelerator pedal to the left. In this system, the accelerator pedal for the left side is attached to a base plate using a knurled screw. A lock for the accelerator pedal on the right is integrated so that the accelerator pedal cannot be accidentally depressed with the prosthetic foot. For people without disabilities, the vehicle can be retrofitted in seconds by removing the knurled screw and taking off the linkage.
