Abstract: With the advent of the intelligent, connected, and electrified automobiles, intelligent connected vehicles have entered millions of households from experimental or research prototype vehicles. The longitudinal driving assistance function plays an important role in reducing the burden on drivers and improving driving safety and comfort. The objective testing and evaluation methods are mainly used for evaluating longitudinal driving assistance functions. Objective evaluation can effectively repeat testing and compare, but some indicators are too professional to be popularized to ordinary users. At the same time, they lack subjective experience and cannot effectively solve users' core demands. Thus objective evaluation can not evaluate the relevant function comprehensively. Therefore, this article proposes a longitudinal driving assistance subjective evaluation method based on closed field testing, combining existing subjective evaluation methods for vehicles and testing scenarios. This method is applied to real vehicle evaluation examples. This article also provides a reference method for the subjective evaluation of intelligent driving related functions.
