Testing automotive ECU performance against various operational conditions

Testing an automotive electronic control unit (ECU) requires an autoranging power supply capable of generating complex voltage transients. Modern vehicles, in general, may have over 100 ECUs to manage a complex and constantly evolving automotive system. As modern vehicles depend more on the ECU, those ECUs must undergo rigorous testing. The ECUs must be able to function in tough environmental conditions or within a system with high electrical interference to ensure reliability and safety to their users.

Manufacturers use the ISO16750 and ISO7637automotive electrical test specifications to perform the electrical disturbance immunity test and exhausting test expected from the actual environment the vehicle will be in after deployment. Autoranging bench DC power supplies are critical and enable engineers to import or generate complex voltage transients derived from the automotive ISO standards to gain insights into the automotive ECU performance.
