1. A vehicle driving assist system comprising:
- a traveling situation detecting section configured to detect a host vehicle traveling speed and a different traveling condition indicative of the host vehicle approaching a designated area; and
an imaginary speed bump generating section configured to selectively generate an imaginary speed bump by artificially reproducing a vehicle behavior in the host vehicle that simulates the host vehicle crossing an actual speed bump arranged on a road surface to alert a driver of the host vehicle that the host vehicle is approaching the designated area and to urge the driver to decelerate the host vehicle, based on the traveling condition being detected by the traveling situation detecting section that the host vehicle is approaching the designated area and the host vehicle traveling speed being detected as higher than a first prescribed speed,the imaginary speed bump generating section being configured to selectively generate the imaginary speed bump by supplying brake fluid pressure to each of right, left, front, and rear wheels of the host vehicle within a single generation of the imaginary speed bump to simulate the actual speed bump across an entire wheel width of the host vehicle,the imaginary speed bump generating section being further configured to prevent generation of the imaginary speed bump when the host vehicle is traveling at a speed that exceeds a second prescribed speed that is higher than the first prescribed speed.

Abstract
A vehicle driving assist system has a controller configured to urge a driver to slow down (decelerate) in locations where visibility is poor. The controller detects a traveling condition of a host vehicle, e.g., when the host vehicle is approaching a designated area, such as a school zone, and then selectively executes an imaginary speed limiting road protrusion control that generates an imaginary speed limiting road protrusion by artificially reproducing a vehicle behavior that simulates the host vehicle crosses an actual speed limiting road protrusion arranged on a road surface, based on the traveling condition of the host vehicle.

18. A vehicle driving assist system comprising:
-
a traveling situation detecting section configured to detect a host vehicle traveling speed and a different traveling condition indicative of the host vehicle approaching a designated area; and an imaginary speed bump generating section configured to selectively generate an imaginary speed bump by artificially reproducing a vehicle behavior in the host vehicle that simulates the host vehicle crossing an actual speed bump arranged on a road surface to alert a driver of the host vehicle that the host vehicle is approaching the designated area and to urge the driver to decelerate the host vehicle, based on the traveling condition being detected by the traveling situation detecting section that the host vehicle is approaching the designated area and the host vehicle traveling speed being detected as higher than a first prescribed speed, the imaginary speed bump generating section being configured to generate the imaginary speed bump by individually controlling stroke lengths of front and rear wheel suspension devices of the host vehicle, the imaginary speed bump generating section being further configured to prevent generation of the imaginary speed bump when the host vehicle is traveling at a speed that exceeds a second prescribed speed that is higher than the first prescribed speed.
