Sound training in hybrid technology

The new and innovative training platform is ideally suited to the requirements for the placement of solid knowledge about hybrid vehicles. The modular and networkable concept allows catchy sub-examination and comparison of all the known hybrid drive systems in the motor vehicle.

Thanks to the diversity of the practical information and the real measured values for the intact and defective vehicle, the present teaching system makes a decisive contribution to the introduction of theory and practical service.

Good Reasons


Special technology

  • Including: All current hybrid drive concepts. With and without plug-in
  • Multi-faceted: Demonstration and function for understanding - trouble shooting and diagnostics for the real-life situations
  • Innovative: E-learning with measuring instruments

Networked goals

  • Recognition and transfer of the correlations. Individually in self-study, head-on in the classroom or in laboratory groups
  • Preparation for workshop practice with or without a teacher centre

Variable and future-oriented

  • Secure: Work without risk in the low voltage range on the high voltage system
  • Equipped: Future hybrid drive concepts by software update
  • Scalable: additional functions with software packets and device panels



Numerous functions are provided for the measurement of all essential components in the intact system and in fault cases. Measurements of electrical values are made here with real measuring instruments. The measurable voltage values are nearly identical to those in the real vehicle and are geared toward the respective operating condition. Voltages lying above the low voltage range in the motor vehicle are at a ratio of 1:10 to the measurement for reasons of accident prevention. The system provides extensive operating modes. In addition to the driving situations,
these include start and charging situations, measurement and diagnostic modes and the work on HV components. The driving situations include the conventional driving mode, the purely electronic driving mode, boosting, recuperation, load point raising, a 16-part driving profile in the EV mode and the new European standard driving cycle.


The networked concept consists of extensive control software and the connected device panels. The integration in the existing Ethernet laboratory network makes it possible for individual fault cases to be switched to the student work stations from the teacher's desk. The system can alternatively be linked by the supplied THERPA Link cable. The teacher can actively access the device panels on his/her computer and thus let the students perform the corresponding troubleshooting. Numerous practical faults can be selectedwhereby several causes can be selected in turn for every fault message. This makes it possible for all students, for example, to switch the message a CAN Bus malfunction or a Water pump for high temperature cooling circuit non-functional, but for each of them to individually determine the cause of the fault. The control by the teacher is carried out with differing amounts of intervention in the student workstation. Thus, each student can have complete control of his/her system or the selection and activation of the functions can be solely up to the teacher.


The modular learning platform a component set for motor vehicle technology is based on the structural logic of a vehicle drive system. The hardware components consist of the central equipment panel a Basic vehicle system and the device panel modules a Inverter and electrical machines and a Battery and high voltage unit. This platform concept makes it possible to later expand the basic system to include additional thematic areas and device panel modules such as petrol injection systems or diesel systems. The device panels primarily serve as measuring
boxes with correlation displays which symbolise and explain the drive mode.
