“First to the market” electronic accelerator pedals from TT Electronics / AB Elektronik GmbH
Product requirements have undergone tremendous development since we launched the first electronic contactless accelerator pedal with Hall-effect sensor technology in 1998. Apart from different technologies and designs for car and commercial vehicle applications, it is the different standards across the world which have had the most varied effect on our portfolio regarding mechanical design and electronic interfaces.
Large volumes and version diversity
Our strength is undoubtedly the diversity of versions and technology our customers can expect. Contactless sensor technologies and potentiometers are to be found in high-end pedals and best cost designs are used as desired. The focus here is just as much on tailoring the product to the particular customer application as on using base components for economic implementation of projects. Special characteristics like flexible mounting to reduce the risk of injury or the special kick-down in commercial vehicles are just a few of the additional advantages for our customers that bolster our market position.
We are proud of being a recognised worldwide partner in development and production for electronic accelerator pedals in renowned OEM car and commercial vehicle applications. In Europe AB Elektronik is the market leader in pedals for the medium and heavy truck segment.
Innovativeness and experience
- Extensive company patents such as the Autopad® sensor technology (inductive, contactless)
- Production of > 3.5 million accelerator pedals annually at our locations in Europe and Asia
Technical diversity for your special requirements
- Suspended and upright designs
- Wide technology portfolio available (potentiometer or contactless Hall-effect or Autopad® sensor technologies)
- Analogue or digital signals
- Different kick-down designs deployable
Other product characteristics
- Compact design
- Change in the force curve by actuators: e.g. information is transmitted via different vibration processes from the pedal plate to the driver
- Optimised crash pedal: reduction in the force acting on the driver's foot in a crash by special mounting of the pedal plate
- Metal surface pedal plates for exclusive vehicle equipment
Several interesting aspects not apparent at first glance:
Driver assistance with active accelerator pedal – haptic prompts
Active pedal communicates via haptic signals with the driver
This kind of communication bypasses the in any case very stimulus-saturated optical and acoustic communication levels and reaches the driver directly, e.g. through vibration or knocking of the accelerator pedal.
Typical features include the support of distance warning systems, speed-related applications and other assistants. Deployment in combination with efficiency parameters is possible too, especially in big vehicle fleets.
An uneconomic driving style can be linked both to an indication of increased fuel consumption as well as an indication to change the drive systems in hybrid or electric vehicles.
Magnetic kick-down - comfort even on long trips!
Magnetic kick-down assists foot support and prevents unintentional gear changing.
In modern commercial vehicles in particular the kick-down plays a crucial role in selecting gears in automatic transmissions. AB Elektronik’s magnetic version, which creates effective added value with regard to fuel economy and ergonomics, has proven its worth here.
The magnetic force provided ensures that the kick-down is not triggered even on bad roads, e.g. by any unintentional foot rocking. This means the driver can relax with his foot on the pedal without causing any potential false actuation - a significant ergonomic advantage on long trips. This cannot be achieved with mechanical solutions and unintentional gear changing occurs repeatedly whenever the pedal engine control receives the signal that acceleration is to be initiated. This leads to increased fuel consumption and wear. When deliberately exceeded the magnetic kick-down effects a safe change in gear, due to the combination of the steep edge forces in this kind of kick-down and the specially adjusted programming of the sensor signal curve.
