Abstract

The invention discloses a vehicle electric control unit flexible HIL test center and a test method, and relates to an HIL test system for vehicle ECU. The vehicle electric control unit flexible HIL test center comprises a test management unit, a real-time systems, a test signal simulation unit, f fault injection units, a resource matching matrix, a sample management unit, a transmission unit, a refreshing station and n test stations which are connected according to related functions. The test method comprises: inputting ECU software, test cases and a controlled object model into the test management unit, and storing ECU hardware in the sample management unit; respectively inputting the test case and the controlled object model into a real-time system; after ECU hardware is transmitted to the refreshing station updating software, sending the ECU hardware to the sample management unit to form a to-be-tested piece; analyzing and obtaining test resources required by each set of test cases;transmitting the to-be-tested piece to a test station; allocating test resources to the test stations; and the real-time system starts to automatically execute the test cases. The HIL test can be quickly, accurately and efficiently finished on the ECU for the vehicle.

Description

technical field [0001] The present invention relates to a hardware-in-the-loop (HIL for short) test system of an electric control unit (ECU for short) used in a vehicle. Specifically, it is a test station that can test a specific HIL according to test requirements and ECU attributes. Flexible configuration of test resources, multiple test stations can flexibly configure the required test resources, and can be applied to different ECU tests without extensive modification of the HIL test bench, and can quickly, accurately and efficiently complete HIL tests for automotive ECUs Flexible HIL test center and test method for vehicle electronic control unit. Background technique [0002] In the automotive industry, the current development model of automotive ECUs has been transformed into a V-process development model. In the V-process development mode, after the software and hardware of the vehicle ECU are integrated, it needs to be tested comprehensively for its functions, interf...
