Abstract:
1. A vehicle drive assist system comprising: ambient-environment recognizing means for recognizing an ambient environment of a vehicle; risk setting means for setting a current risk for an object in the recognized ambient environment; risk-change predicting means for predicting a temporal change in risk by predicting a temporal change in a position of the object; minimum calculating means for calculating a minimum of the risk at a position of the vehicle at each time on the basis of the predicted temporal change in the risk; turning-control-amount calculating means for calculating a turning control amount of the vehicle on the basis of at least the minimum; and avoidance-route determining means for determining a final avoidance route by generating an avoidance route of the vehicle on the basis of the turning control amount, wherein the minimum calculating means calculates the minimum of the risk by partial differentiation in a width direction of the vehicle.
