Problems solved by technology
However, the vehicle environment is relatively harsh, and the vehicle may be driven and parked in various environments. The vehicle multimedia system needs to withstand the test of various extreme environmental conditions such as high temperature, low temperature, high and low temperature alternation, and light aging. Reliability puts forward higher requirements
At present, there is no special method for analyzing the reliability of the vehicle multimedia system, which leads to the vehicle multimedia system is prone to failure, the failure rate of the vehicle multimedia system cannot be estimated, and the weak links of the vehicle multimedia system cannot be found

Embodiment Construction
[0025] The present invention will be further described below in conjunction with accompanying drawing:
[0026] The vehicle multimedia system adopts the scoring assignment method for analysis and detection. The analysis and detection of the vehicle multimedia system includes the reliability distribution of the vehicle multimedia system, the reliability modeling of the vehicle multimedia system, the prediction of the reliability of the vehicle multimedia system, and the calculation of the failure rate of the vehicle multimedia system. Scoring is based on the complexity, technology maturity level, working time, failure consequences and environmental conditions of each module / component as scoring factors. Experts in this field are invited to score, and the scoring factors of a module or component at an assigned level are multiplied , and then average the results of multiplying the scoring factors of multiple experts, and finally weight the average to obtain the failure rate of a s...

Description
technical field [0001] The invention relates to the technical field of vehicle-mounted multimedia, in particular to a reliability analysis method for a vehicle-mounted multimedia system. Background technique [0002] With the development of science and technology, embedded systems are widely used in vehicle multimedia systems. However, the vehicle environment is relatively harsh, and the vehicle may be driven and parked in various environments. The vehicle multimedia system needs to withstand the test of various extreme environmental conditions such as high temperature, low temperature, high and low temperature alternation, and light aging. Reliability puts forward higher requirements. At present, there is no special method for analyzing the reliability of the vehicle multimedia system, which causes the vehicle multimedia system to be prone to failure, the failure rate of the vehicle multimedia system cannot be estimated, and the weak link of the vehicle multimedia system c...
