车辆底盘评价项目中的制动踏板感觉其客观分析已经在国内制动系统行业获得了较为广泛的研究,不同的制动踏板感觉客观数据的采集和处理方法直接影响到制动踏板感觉的优化效果。对制动踏板感觉客观数据的采集要点进行分析,并研究零相移数字滤波器的特点,分析filtfilt滤波函数对制动踏板感觉客观数据的处理效果,在此基础上,提出一种制动踏板感觉试验数据采集和分析的标准化方法,以便客观地比较不同试验结果。
The brake pedal in the vehicle chassis evaluation project has its objective analysis of the brake pedal has been more widely studied in the domestic brake system industry, different brake pedal feel objective data collection and processing methods directly affect the optimal effect of the brake pedal feel . This paper analyzes the main points of collecting objective data of brake pedal feeling, and investigates the characteristics of zero phase shift digital filter and analyzes the effect of filtfilt filter function on the perception of objective data of brake pedal. On this basis, a brake pedal Sensory test Data collection and analysis of standardized methods to objectively compare different test results.
