车型对不同制动工况下车辆特征信号的影响

Influence of Vehicle Types on Vehicle Characteristic Signals under Different Braking Conditions

采用全面试验设计方法进行了多车型不同制动初速度下制动实验,并用双向方差分析方法分析车速和车型对制动加速度均值及制动踏板角速度的均值影响.结果表明,紧急制动与非紧急制动的特征信号差异明显,不同车型对两特征信号均有一定的影响.

Based on the comprehensive experimental design method,brake experiments were made for multi-type vehicle under different initial braking speeds,and then the effects of speed and vehicle types on mean of braking acceleration and pedal angular velocity were analyzed by means of two-way variance analysis method. The results showed that characteristic signals were obviously different for emergency braking and non-emergen-cy braking due to different vehicle types.
