Wiring Concepts in Test Vehicles
For the test phase, several hundred sensors must be installed in a test vehicle in
various areas, e.g. in the engine compartment and in the floor area. The sensors,
which are positioned all over the vehicle, then have to be connected to the mea-
suring instruments of the test setup.
Today’s standard solutions with their central setup of measuring instruments
inside the vehicle require complex cabling to connect the widely distributed sen-
sors with the measuring instruments. Numerous, usually long connection cables
between the sensors and the measuring instruments, bundled together to form
several fat wiring harnesses, require a highly modified splash wall of the test
vehicle. This involves long setting-up times as well as high costs.

Central and Decentral Sensor Cabling
With the ES400 modules, ETAS provides a decentral solution which considerably
simplifies the test setup of the sensors.
The basic idea of this concept is to install the modules of the ES400 family as
close as possible to the sensors, to concatenate the modules with each other and
to connect just the first module of this chain with the laptop in the vehicle.
