| ABSTRACT |
|
Global automakers are required to apply Automotive SPICE (A-SPICE) to evaluate the development
capabilities and qualities of suppliers in addition to the automotive functional safety standard (ISO 26262) for preventing
accidents caused by errors in the electronic components. However, rapidly changing software requirements and environments
make it difficult to follow A-SPICE and ISO 26262, leading to late detection of software defects in the system qualification
test, which is the final verification stage of the V-model. Correcting these defects incurs additional time and cost. This study
proposes an enhanced qualification test strategy and technique, which ensures zero defects at an early stage, thereby saving
time and cost. The proposed strategy and technique are performed by advanced exploratory and optimization tests that utilize
a risk-based test strategy to solve problems. The risk-based test strategy is established at the beginning to identify highly
potential problems and is derived from the 1st stage advanced exploratory and 2nd stage optimization tests based on ISO
29119. The test is performed during a CDC system qualification test using an “advanced HILS,” which supports UDS and
XCP protocols. The proposed test techniques can solve problems during an early phase and achieve zero defects in a CDC
system qualification test. |
