MORE AUTOMATION for ECU testing

The latest fault-insertion tests enable engineers to run more test cases in less time.

Testing safety-related Electronic Control Units (ECUs) is as much about software testing as hardware. Increased intelligence within ECUs to control braking, prevent rollovers and ensure that power is applied to the correct wheels is critical. Automotive Tier 1s such as Delphi, Magna Powertrain and Continental share these concerns.

Transfer cases for four-wheel-drive and all-wheel-drive vehicles are a mechanical/electronic device that monitors wheel slippage and ensures that torque is transferred to the wheels that are not slipping. A transfer case ECU connects to sensors and actuators, as well as interfaces with the vehicle's network. When a driver shifts into gear, the ECU determines if it can perform this shift. Upon completion, the ECU reports this to the network.
