The invention discloses a method and system for testing and evaluating the comfort level of an automatic driving vehicle based on an automatic driving robot, wherein the method comprises the steps: controlling a vehicle to carry out preset movement through the automatic driving robot, meanwhile, recording the electrocardiogram data of the tested driver in the whole predetermined vehicle movement process and objective vehicle state information controlled by the automatic driving robot; and performing, by the driver, subjective comfort feeling evaluation according to a subjective evaluation standard; carrying out R wave extraction and time domain calculation on the electrocardiosignals to obtain time domain indexes SDNN and RMSSD representing heart rate variability, and carrying out variance analysis to obtain objective data which have significant difference and can represent comfort; finally, according to the objective data and the subjective evaluation data, performing cross comparison to obtain the optimal vehicle motion state parameters conforming to the comfort level of the driver. The method has very high precision for controlling the comfort level of the vehicle motion state, has very high repeatability and usability, and has very good compatibility for different working conditions.

    本发明公开了一种基于自动驾驶机器人的自动驾驶汽车舒适度测试评价方法和系统,包括:通过自动驾驶机器人控制车辆进行预定的运动,同时记录受试驾驶员在整个预定车辆运动过程的心电数据和自动驾驶机器人控制的车辆状态客观信息;驾驶员根据主观评价标准进行主观舒适度感受评价;对心电信号进行R波提取,时域计算,得到表征心率变异性的时域指标SDNN和RMSSD,方差分析,得到显著差异性、能够表征舒适性的客观数据;根据客观数据和主观评价数据,进行交叉比对,得到符合驾驶员舒适度的最佳车辆运动状态参数。本发明对于车辆运动状态舒适度的控制具有很高的精度,具备很强的可重复性和易用性,并且对不同工况有很好的兼容性。
