Abstract: The article addresses market feedback issues, based on real-world usage scenarios of users, it establishes subjective and objective evaluation targets for improving the comfort of a P1-39# electric vehicle, and a preliminary analysis of potential problems in handling stability and comfort. During the tuning process, analyses and adjustments are conducted on spring scheme selection, damper matching, seat improvement solutions, and steering portability tuning. After tuning, the vehicle comfort showes significant improvement compared to the pre-optimization state, achieving a better balance between handling stability and comfort. While handling stability slightly decreases, it remains superior to competing vehicle. Furthermore, through post-project review, it provides some reference methods for setting target values and tuning in future vehicle models.
