Vehicle communication system using projected light

A driving assist system for a vehicle, said driving assist system comprising:

• a plurality of sensors disposed at a vehicle and having respective fields of sensing exterior of the vehicle;
• wherein said plurality of sensors comprise a plurality of cameras disposed at the vehicle and having respective fields of view exterior of the vehicle;
• wherein said plurality of sensors comprise a plurality of radar sensors disposed at the vehicle and having respective fields of sensing exterior of the vehicle;
• a control comprising a data processor that processes data captured by said plurality of sensors;
• a projection device disposed at the vehicle and operable to project light exterior of the vehicle;
• wherein said control, via processing at said control of captured data, determines a current path of travel for the vehicle;
• wherein said control, via processing at said control of captured data, determines presence of a pedestrian at or near or approaching the determined current path of travel for the vehicle and determines a current location of the determined pedestrian relative to the vehicle;
• wherein, responsive to determination of the pedestrian and determination of the current location of the determined pedestrian relative to the vehicle, said projection device (i) projects light onto the ground that is indicative of the determined current path of travel of the vehicle for viewing by the determined pedestrian and (ii) projects an alert icon onto the ground at or near the determined current location of the determined pedestrian to alert the determined pedestrian that the determined pedestrian is at or near or approaching the determined current path of travel of the vehicle;
• wherein, said control, via processing at said control of captured data, determines movement of the determined pedestrian relative to the vehicle and determines an updated location of the determined pedestrian as the pedestrian moves relative to the vehicle, and wherein, based at least in part on the movement of the determined pedestrian, said projection device adjusts projection of the alert icon to project the alert icon onto the ground at or near the determined updated location of the determined pedestrian;
• wherein said control, via processing at said control of captured data, determines surface variations of a surface profile of the ground at or near the determined pedestrian;
• and
• wherein said control adjusts said projection device to adjust display of the projected light of the alert icon on the ground at or near the determined pedestrian based in part on the determined surface variations of the surface profile of the ground at or near the determined pedestrian.

• wherein said control, via processing of captured data, detects presence of an object at or in the determined current path of travel of the vehicle;
• wherein said control, responsive to detection of the object at or in the determined current path of travel of the vehicle, adjusts the determined path of travel of the vehicle to avoid the object;
• wherein, responsive to determination of the pedestrian and determination of the current location of the determined pedestrian relative to the vehicle, said projection device projects light onto the ground that is indicative of the adjusted determined path of travel of the vehicle for viewing by the determined pedestrian;
• wherein, responsive to determination of the pedestrian and determination of the current location of the determined pedestrian relative to the vehicle, said projection device projects an alert icon onto the ground at or near the determined current location of the determined pedestrian to alert the determined pedestrian that the determined pedestrian is at or near or approaching the adjusted determined path of travel of the vehicle;

• and
• wherein said control adjusts said projection device to adjust display of the projected light of the alert icon on the ground at or near the determined pedestrian based in part on the determined surface variations of the surface profile of the ground at or near the determined pedestrian.
