Embodiment Construction
[0048] In order to enable those skilled in the technical field to which the application belongs to understand the application more clearly, the technical solutions of the application will be described in detail below through specific embodiments in conjunction with the accompanying drawings.
[0049]The establishment of road vehicle functional safety management process mainly needs to complete the 7 stages of management, conceptual design, system development, hardware development, software development, manufacturing and support activities, and more than 100 work outputs, which not only makes the establishment of a complete The road vehicle functional safety management process takes a long time and requires a large amount of work.
[0050] Through analysis and practice, it is found that some program documents, norms and CMMI three-level (Capability Maturity Model Integration For Software) management processes in the ISO9001 quality system are more related to road vehicle functio...

The invention discloses a method and system for establishing a vehicle function safety management process, and the method comprises the steps of screening files of an ISO9001 quality system and files of a CMMI three-level development process according to ISO26262, and determining preliminary file contents similar to the content required by the ISO26262; in the preliminary file content, determining a first part which completely meets the content required by the ISO26262 and a second part which is different from the content required by the ISO26262; and directly multiplexing the first part and correcting the second part to respectively obtain the first file content and the second file content; in addition, newly building third file content which is not covered by the ISO9001 quality system and the CMMI three-level development process according to the content required by ISO26262; and establishing a vehicle function safety management process according to the first file content, the second file content and the third file content.
Description
technical field [0001] The present application relates to the technical field of automobile manufacturing, in particular to a method and system for establishing a vehicle functional safety management process. Background technique [0002] As the complexity of vehicle electronic control systems increases, more and more software and electrical equipment are used, and the risks from system and software and hardware failures are also increasing. Once the failure occurs, it will not only endanger the lives of vehicle drivers and pedestrians, but also cause vehicle manufacturers to face huge risks of loss of profits and goodwill due to events such as vehicle recalls and compensation. How to avoid these risks has become an urgent issue for auto companies. topic. [0003] ISO 26262 provides feasible requirements suggestions and process specifications to avoid these risks. It is the specific application of IEC 61508 (GB / T 20438) to the functional safety requirements of road vehicles...
