The invention discloses a rainy day vehicle braking distance estimation method based on an intelligent tire. According to the method, the vehicle braking distance S can be estimated through the road surface accumulated water depth N, the tire inflation pressure P, the vehicle vertical load T, the tire pattern longitudinal groove width D and the tire tread abrasion E. According to the method, the road surface accumulated water depth is considered, the tire inflation pressure, the vehicle vertical load, the tire pattern longitudinal groove width and the tire tread abrasion are combined, the purpose is to estimate the vehicle braking distance under the extreme road condition in rainy days, and the safety of a driver during braking is guaranteed.
本发明公开了一种基于智能轮胎的雨天车辆制动距离预估方法,可以通过路面积水深度N、轮胎充气压力P、车辆垂向载荷T、轮胎花纹纵沟宽度D以及胎面磨损E预估车辆制动距离S的办法。该方法考虑了路面积水深度,结合轮胎充气压力、车辆垂直载荷、轮胎花纹纵沟宽度以及胎面磨损,目的是针对雨天极端路况下的车辆制动距离进行预估,保证驾驶人员在制动时的安全性。
