Application Notes
An automotive Electronic Control Unit (ECU) is an embedded system that controls the vehicle’s electrical and electronic components, such as fuel injection, spark ignition control, braking, suspension, power steering control, alternator, and more. Modern vehicles, in general, may contain more than 100 ECUs to manage an ever-increasingly sophisticated automotive system. As modern vehicles become progressively more reliant on the ECU, it is vital that those ECUs are thoroughly validated and able to operate in harsh environmental conditions or within a system with high electrical disturbance to ensure reliability and safety to its user.
ISO16750 and ISO7637 automotive electrical test specifications have been developed just for this purpose to systematically guide manufacturers in performing the electrical disturbance immunity test and vigorous test anticipated from the actual environment in which the vehicle will be exposed once deployed. The Keysight E36150 Series Autoranging Bench DC Power Supply supports the new feature that allows you to import or generate complex voltage transients derived from the automotive ISO standards, which is suitable for the automotive electrical test.
This Application Note demonstrates how you can leverage this power supply’s new features to help you quickly perform the automotive ISO electrical test to gain insight into your automotive ECU performance.
