摘　　要：为满足汽车乘坐舒适性研究的需要,对实车进行了改装,开发了具有多个可调节自由度的汽车舒适性评价试验平台,设计并实现了可调节式踏板机构,提出了基于编码器绝对转数的座椅高度算法。实际测试结果表明,经实车改装的试验平台测试精度高、性能稳定、可调节参数及调节范围充裕、安全可靠,可为汽车乘坐舒适性研究提供可靠的测试依据和试验手段。A 2007 SGM Buick Park Avenue was modified to satisfy adjustability requirements for automobile seating comfort studies. It was designed with multi--degrees of freedom to control each adjustable feature. Adjustable pedal mechanism was proposed and implemented. Algorithm to obtain seat height from absolute encoder revolutions was developed. Test data is presented to validate that the modified car test bench is a reliable platform for seating comfort studies with high precision, stable performance and abundant adjustable parameters.
