Accelerated automotive design using HIL simulation
This article examines the use of hardware-in-the-loop (HIL) simulation to test embedded components in cars before final deployment. HIL provides a realistic simulation of equipment in an operational virtual environment and involves sensors, actuators to send data, a controller, an interface and an analysis platform. Dynamic testing of components in use with HIL is integrated to the design cycle. An example is given of an anti-lock braking system which uses an electronic control unit (ECU) to provide closed-loop control of the vehicle's brakes. HIL simulation must be able to interface electrically with the ECU and determine the correct values to be produced relative to signals received from the ECU, with accurate timing characteristics. This requires a real-time operating system. As a vehicle's electronics become more complex and more important to its operation, development cost and time increase. HIL simulation enables testing earlier in the development cycle and improves the capacity, coverage, flexibility and repeatability of tests.
