Patent ID: 8060305

Claim:
A computer-implemented vehicle driving assist system comprising: a risk factor detection section configured to detect a plurality of potential risk factors related to a host vehicle, the risk factor detection section being further configured to detect a vehicle running state that is attributed to kinetic energy of the host vehicle as at least part of a first risk factor of the risk factors and detect a travel rule attributed to the host vehicle as at least part of a second risk factor of the risk factors, both of the first and second risk factors being unrelated to an obstacle around the host vehicle; a first risk potential calculation section configured to calculate a first risk potential attributed to the first risk factor from the risk factors that are detected; a second risk potential calculation section configured to calculate a second risk potential attributed to the second risk factor that is different than the first risk factor from the risk factors that are detected; and a risk potential notification section configured to notifying a driver of the first risk potential calculated by the first risk potential calculation section with a first risk potential notification and the second risk potential calculated by the second risk potential calculation section with a second risk potential notification using a common risk notification device for both the first and second notifications with the first and second notifications being different.
