Abstract

The invention relates to a driving assistance system, a driving assistance method, and a computer-readable recording medium. The invention provides a driving support system which can restrain troubles and uncomfortable feelings brought to a driver and can reduce collision risks caused by objects in front of a vehicle. According to this driving support system, risk target information relating to a risk target that is the presence of a risk of collision in a vehicle is extracted from information about the surroundings of the vehicle. Further, influence factor information relating to an influence factor that is a factor existing independently of the risk target and that affects the collision risk is acquired. Furthermore, a risk value that quantifies the risk of collision is determined on the basis of the risk target information and the influence factor information, and the amount of operation of the actuator is determined so as to reduce the risk of collision on the basis of the determined risk value.

Description

technical field [0001] The present invention relates to a driving assistance system for assisting driving of a vehicle, a driving assistance method, and a computer-readable recording medium storing a driving assistance program. Background technique [0002] When a pedestrian / bicycle suddenly rushes from a wall or the blind spot of a parked vehicle, the conventional AEBS brake cannot perform sufficient deceleration and avoidance, and a collision may occur. Therefore, Patent Document 1 proposes a "risk field method" in which a blind spot position recognition is performed and an imaginary pedestrian is assumed based on the distance between the vehicle and the blind spot / lateral clearance / relative speed The collision prediction speed after the AEBS work in the run-out is defined as the potential risk value. If deceleration or lateral avoidance is performed until the potential risk value (collision prediction speed) assumed here becomes zero, the blind spot can be passed safely....
