基于驾驶舒适度的刹车策略

Braking Strategies Based on Driving Comfort

为了研究刹车过程中驾驶员的驾驶舒适度与踏板力的关系,以刹车过程中汽车加速度作为驾驶舒适度的量化指标,建立汽车动力学模型和多目标优化的方法,得到驾驶舒适度、制动距离和踏板力三者的数学关系模型,利用MATLAB软件分析该数学关系模型,得到最小踏板力。结果表明,通过多目标优化方法得到的最小踏板力使得制动距离小于安全距离,同时驾驶舒适度最好。

To study the relationship between driving comfort of drivers and pedaling force during braking,the vehicle acceleration in braking process was used as a quantitative indicator of driving comfort,and the mathematical relationship model of driving comfort,braking distance,and pedal force was obtained by using the vehicle dynamics model and multi-objective optimization method.The mathematical relationship model was analyzed by using MATLAB software to obtain the minimum pedal force.The results show that the minimum pedal force obtained by using the multi-objective optimization method makes the braking distance less than the safety distance,and the driving comfort is the best.
