BTS - BODY ELECTRONIC TEST SYSTEM

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.
