VEHICLE SHORTEST STOPPING DISTANCE PREDICTING METHOD AND VEHICLE SHORTEST STOPPING DISTANCE PREDICTING DEVICE

摘要

PROBLEM TO BE SOLVED: To improve its predicting accuracy in a device to predict the shortest stopping distance of a vehicle by a brake. SOLUTION: The shortest stopping distance D5 when braking initial velocity is a vehicle speed D4 is predicted by performing an operation by substituting vehicle weight D1 detected by a vehicle weight sensor 10, a tire width D2 detected by a tire width sensor 12, a tire dynamic load radius D3 detected by a tire dynamic load radius sensor 14 and the vehicle speed D4 detected by a vehicle speed sensor 16 in predictive expressions previously prepared with every vehicle speed D4, and its predictive value is displayed for a driver by a display 40.
