Description

Controller OTA upgrading intelligent rapid switching test system compatible with multiple vehicle types, method, medium and equipment Technical Field The invention relates to the technical field of automobile electronics, in particular to a controller OTA upgrading intelligent rapid switching test system compatible with multiple automobile types, a method, a medium and equipment. Background With the continuous promotion of the intelligent and networking degree of the automobile, the OTA upgrade becomes a core means of the function iteration, fault repair and experience optimization of the vehicle-mounted controller, and the upgrade reliability of the OTA upgrade is directly related to the running safety and user experience of the whole automobile, so that the OTA test bench is a key device for verifying the upgrade reliability of the controller. The bench core composition comprises a test upper computer, a BOB control box, a tested ECU, a power module, a bus simulator and the like, wherein the BOB control box is used as a transfer hub of the ECU and the bench system, plays the core roles of signal transfer and fault injection, and is a key component for guaranteeing the whole flow of OTA test to fall to the ground. The current automobile market models are diversified, the same type vehicle-mounted controllers (such as VCUs) of different models are developed by different suppliers, and although hardware interface definition and power supply requirements follow industry universal standards, parameters such as actual wiring layout, wire harness specification, CAN baud rate and the like have significant differences, so that the existing bench cannot be directly adapted to the testing of the multi-model controllers. Meanwhile, the requirements of the industry on the testing efficiency and the intelligent level are continuously improved, the requirement of batch testing is difficult to meet in the traditional testing mode relying on manual operation, and technical breakthroughs are needed in the aspects of compatibility, intelligence and the like. A typical implementation scheme of the existing OTA test bench comprises the steps that a single BOB control box is in one-to-one connection with a tested controller through a special wire harness, a CAN_L/CAN_H interface of the BOB is directly connected with corresponding pins of the controller, KL15, KL30 and a GND power supply interface are also directly connected with power supply pins of the controller through independent wire harnesses, faults such as power failure of the controller to be tested are set through the BOB control box during testing, and basic tests such as condition inspection, retry rollback upgrading and the like before upgrading are completed. And when a plurality of groups of test units are built in parallel, a plurality of sets of matched wiring harnesses are required to be configured synchronously, so that the maintenance cost of equipment and the management difficulty of a bench are further increased. The test of the existing scheme has the following defects: If another vehicle type controller needs to be tested, the connecting wire harness of the original controller and the BOB needs to be disconnected firstly, the wire harness is reconnected after the controller which is matched with the new vehicle type is replaced, then the bench environment (such as CAN baud rate configuration and DBC file importing) is manually debugged to carry out the test, the time consumption of single type changing is usually more than 60 minutes, and the efficiency loss of batch test is remarkable; the BOB box resource waste is that if the number of controllers to be tested is large, a plurality of groups of test units of the BOB+ controllers are required to be built, a large amount of rack space and equipment resources are occupied, the equipment purchasing cost is increased, and the utilization rate of the rack space is low; the operation risk is high, the frequent disassembly of the wire harness is easy to lead to pin abrasion and poor contact of the wire harness, the probability of test failure is increased, and the accuracy of a test result is affected; The intelligent degree is low, the test flow completely depends on manual intervention, the test flow comprises test object switching, test parameter configuration and test result recording, automatic configuration and scheduling capability are lacked, batch unattended testing cannot be achieved, the power supply module output voltage is required to be manually matched with a vehicle type, the operation is complex, a CAN bus is not specially designed in an isolated mode, the stability of a rack is affected, the test result CAN only record upgrade process data of a single vehicle type, a systematic analysis function is lacked, and the controller optimization decision of a whole vehicle factory is difficult to support. Therefore, the OTA upgrade test system which is compatible with multiple vehicle types, support
