Abstract:
1. A vehicle driving assist system comprising: road-surface friction coefficient estimating means configured to estimate a road-surface friction coefficient of a road where a vehicle is running; ground-load estimating means configured to estimate a ground-load acting on a tire of the vehicle; permissible tire-force estimating means configured to estimate a permissible tire-force being capable of acting on the tire on the basis of the road-surface friction coefficient and the ground-load; current tire-force estimating means configured to estimate a current tire-force currently acting on the tire; tire-force margin calculating means configured to calculate a tire-force margin by subtracting the current tire-force from the permissible tire-force; and actuator controlling means configured to activate an actuator warning a driver of the vehicle about the tire-force margin in accordance with a magnitude of the tire-force margin.
