In the simplest terms, hil testing is a method to validate a software in a simulated environment where ecu functions can be tested without having the actual vehicle system.

Hil hardware in the loop. Hil testing is used to validate the communication, system integration and the functionality aspect of automotive software. Hil’s rise is the result of two major factors currently affecting product development across all industries: To bridge this gap, power amplifiers are inserted between duts rated for higher power and the low.

You can also use hil to determine if. With hil simulation the physical part of a machine or system is replaced by a simulation. It is scalable from small to large systems and can be used flexibly from components testing to simulating complete virtual vehicles.

Hil helps to test the behavior of your control algorithms without physical prototypes. Since an ecu interfaces with a vehicle through analog, digital, and bus (or messaging) inputs and outputs, an ecu can be physically tested by generating and consuming. A revolution in the industry.

By allowing ecus under test to interact with a simulated use case, you are free to test early and often to uncover as many software defects as possible. These logs vary in format, but often are captured and stored as mdf4, adtf, rosbag, or other data logger proprietary formats.

Today, all vehicles contain ecus which are systems defined by inputs and outputs, and which integrate control laws in charge of controlling systems (such as adas , air conditioning,. Using a broad definition, one could say that an hil system is a test system where the embedded software under test is executed on the same control unit (ecu, micro controller or other type of embedded control unit) that it will run on in its intended end. Employing simulation, hil engineers can validate embedded controllers (ecus) earlier in the design cycle to save time and improve test coverage.

The hil system loads sensor data derived from test drive logs. Hil simulation shows how your controller responds in real time to realistic virtual stimuli. Hil is the acronym for hardware in the loop.
