ES5340 – PCI Express Simulation Boards

ETAS ES5340 PCI Express simulation boards are an integral part of LABCAR HiL systems. They are used to simulate motors and inverters for powertrains and are designed to meet extremely high demands in terms of speed and precision.

There are two types of PCI Express board for simulating electric motors and inverters for electrified powertrains and combustion engines.

The ETAS ES5340-M electric motor simulation board simulates signals that are typically required for testing an inverter/electric motor ECU. As such it allows ECUs for inverters and electric motors to be tested at signal level.

The ETAS ES5340-ICE combustion engine simulation board is used in acquiring, evaluating, and generating angle-synchronous ECU signals for two-stroke and four-stroke combustion engines.

The signals are preprocessed on the board before being relayed to the LABCAR-RTPC simulation target. This means the signals can be processed extremely efficiently.
