Handheld Devices for the control of electrical vehicle components

Handheld devices for the power supply, bus simulation and motor control of mechatronic systems in the vehicle body and interior

In modern automotive engineering, many functions in the vehicle are electronically supported. For that reason, vehicle components such as seats, tilting/sliding sunroofs, convertible roofs, electric windows, electric trunk lids, and many others can only be operated or adjusted when connected to a power supply.   

However, during prototyping, production, and repair operations, as well as in workshops and upholstery shops, it is often necessary to test the functionality of these components both inside and outside the vehicle.    

The Handheld Devices for the control of electrical vehicle components provide compact and mobile tools that enable users to test and adjust electric components throughout their entire range of travel as well as the testing adjustments paths.

Residual bus simulation, for example, makes it possible to adjust a seat both inside and outside the vehicle. In addition, the portfolio of Handheld Devices for power supply, bus simulation and motor control features a vehicle-independent electrical circuit that can be powered by standard Makita or Bosch batteries.      

The end user can also read, control, and operate other vehicle control units via a CAN/LIN bus.


We already have seven years of market experience in the field of equipment development and production.
Our customers include the major suppliers to the automotive industry as well as major OEMs and their subsidiaries.

This motor control device can be used to control 4 motors in parallel. They are controlled individually by 2 Hall-effect sensors each (e.g. Seat Mover 3rd Row).

Versatile operation of the mover via numerous buttons and an informative display.

Operation of seat motors via the seat adjustment switch or automation via external control in the mover

  • Seat heating, seat ventilation, massage function, neck heating

Operation of electric windows and electric sun blinds directly or via vehicle control units

  • Unlocking the door lock and soft-close function

Operation of the electric steering column adjustment in height (rake) and reach

  • Transfer of the position values to other CAN participants or output to test stands, etc. 

Automatic folding and unfolding of the exterior mirrors and adjustment of the windows.

  • Activation of the functions: indicators, heating, low-beam/high-beam, LED blind spot warning

And much more besides!

  • Powerful, flexible, and universal hardware platforms

  • Many years of experience in production and in this development environment

  • Devices with measuring and analytical capability

  • User-friendly display and operating concept

  • Updatable and configurable software

  • High reliability against failure, at the same time with low-maintenance

  • Fast spare parts availability or repair service

  • Individual operating instructions

  • Robust housing

  • Industrial-grade and contact-friendly plug connections

  • Ergonomic and practical geometry

  • Serial number system for production tracking

  • End user handling or special developer functions

  • Independent and variable power supply

  • Factory integration as a service

All Handheld Devices can be optionally developed and ordered with spring-loaded connectors. The connectors are made of hard-wearing, resilient plastic and are fitted with gold-plated spring-loaded connector pins. Using this kind of connector minimizes the load on the pins on the customers’ components. Implementation possibilities range from simple plugs to plugs with connection guides and spring-loaded locking elements. Different pin sizes and any kind of pin type can be combined.
