Product Description

The Body Electronic Test System (BTS) enables automotive OEMs to execute ECU testing projects alongside Technica Engineering´s team. It provides the user with a wide testing scope, which allows for the realization of complex testing projects. Hence, it has achieved great market acceptance and adaptability.

Given our BTS’ 12x configurable channels, which support CAN, LIN, FlexRay and use the SOME/IP’s protocol to communicate, this test system can adapt to different customer requirements. It features 1x controllable relay channel to aid the user.

As a highly scalable Hardware-in-the-Loop (HiL) test system, Technica Engineering’s Body Electronic Test System (BTS) was designed to automatically validate Body&Comfort ECUs (domain controllers). We can configure it according to your requirements, the BTS includes all common hardware interfaces and systems from the body electronics environment and can be used to test any complex, central ECU.

The BTS is above all characterized by the fact that real loads can be realized. The in-built continuous voltage and current measurement on the Analogue and Digital Inputs/Outputs, as well as the short-cut features alongside the CAN, FlexRay and LIN interfaces using Automotive Ethernet (SOME/IP), make it unique in the market.

The core of the BTS is a generic signal card that provides all the necessary inputs and outputs. A software interface can be used to configure a highly diverse range of requirements. Up to 32 basic cards can be operated in parallel, thus making it possible to simulate up to 448 Input / Output channels at the maximum capacity level. Therefore, the BTS can optimally be adapted to individual project needs.

All-in-all, with Technica Engineering’s Body Electronic Test System (BTS), we provide a setup to successfully develop and validate ECUs by working with a very strong all-round test bench for multi-purpose testing.

Technical data


  • Simulation of up to 448 inputs- / outputs at maximum capacity
  • 12 × configurable digital and analogue (including PWM) I/O channels, with in-built voltage and current measurement
  • 1 × controllable relay channel, with in-built voltage and current measurement
  • 1 × controllable low current source channel (current < 35mA), with in-built voltage and current measurement
  • 2 × High/Low Speed CAN
  • 2 × LIN buses
  • 1 × FlexRay

  • Fully configurable by software: Each channel can be configured independently as Input or Output
  • The Open-Load, short-circuit to ground or to VBAT fault states can be simulated for all channels
  • All channels feature a double self-protection function to avoid damage to the BTS base boards or the connected device
  • HW Protection to avoid a current higher than 2A
  • SW protection with configurable threshold current per channel
  • Time synchronization between boards through CAN interface
  • For connection of hardware extensions to expand the functions of the base board, a connector with power and control/communication interfaces (3x SPI, I2C) is provided
  • Two possibilities to report changes in I/O Channels: Cyclic or On Event
  • Playback of stored patterns, for cases where timing is a critical factor
