Abstract:
1. A vehicle driving assist system comprising: a traveling situation detecting section configured to output a traveling situation detection result based on at least a distance between a host vehicle and an obstacle existing in front of the host vehicle and a speed of the host vehicle; a relative position calculating section configured to calculate a positional relationship between the host vehicle and the obstacle based on the traveling situation detection result of the traveling situation detecting section; an accelerator pedal actuation state detecting section configured to detect an accelerator pedal actuation state of an accelerator pedal of the host vehicle by a driver; a control pattern selecting section configured to select a vehicle control pattern from among at least two vehicle control patterns as a selected vehicle control pattern based on the accelerator pedal actuation state detected by the accelerator pedal actuation state detecting section and the positional relationship between the host vehicle and the obstacle calculated by the relative position calculating section; a risk potential calculating section configured to calculate a risk potential that indicates a degree of convergence between the host vehicle and the obstacle based on the traveling situation detection result of the traveling situation detecting section, the calculation being executed in accordance with the selected vehicle control pattern; and a control section configured to control a control force of at least one of an actuation reaction force exerted by the accelerator pedal and a braking/driving force exerted against the host vehicle based on an amount of the risk potential calculated by the risk potential calculating section, the at least two vehicle control patterns each having a different relationship between the control force and the amount of the risk potential.
