Abstract: Addressing the issues associated with traditional automotive dynamic acceleration performance testing, such as reliance on high-cost professional equipment and complex operations, this paper innovatively proposes a low-cost, high-efficiency testing method and data processing system based on universal smartphones and software. By collaboratively using two smartphones to collect vehicle speed and time data and employing WPS spreadsheets for automated data processing, this approach resolves pain points in traditional testing, including strong equipment dependency and low data processing efficiency. Experiments demonstrate that the deviation rate of this method is less than 2% in key automotive acceleration performance indicators such as 0–100 km/h acceleration time and 0–400 m acceleration time. Moreover, ordinary engineers can master the entire operational process after short-term training. This research provides an economical and efficient alternative solution for automotive dynamic acceleration performance testing.
