Vehicle stop support system

A vehicle stop support system for supporting stop of a vehicle which is traveling, comprising:

• an abnormality detection part for estimating a disorder or a disease developing in a body of a driver;
• a target time period setting part for setting a target time period based on the disorder or the disease estimated by the abnormality detection part;
• a candidate detection part for detecting a plurality of stop point candidates which exist in a traveling direction of the vehicle;
• a required time period estimation part for estimating a time period required to reach each of the stop point candidates;
• a risk estimation part for estimating a rear-end collision risk which is a risk that, when assuming that the vehicle stops at each of the stop point candidates, the vehicle will be rear-ended by a following vehicle;
• a stop point setting part for setting a stop point;
• and
• a vehicle control part for controlling the vehicle to travel to the stop point and stop at the stop point,
• wherein the vehicle stop support system is configured to execute the following steps in order:
• a first step of estimating the disorder or the disease developing in the body of the driver;
• a second step of setting the target time period based on the disorder or the disease estimated in the first step;
• a third step of detecting the plurality of stop point candidates;
• a fourth step of estimating the time period required to reach each of the stop point candidates detected in the third step;
• a fifth step of narrowing down the plurality of stop point candidates detected in the third step by selecting and leaving, among the plurality of stop point candidates detected in the third step, one or more stop point candidates each satisfying a condition that the required time period estimated in the fourth step is equal to or less than the target time period set in the second step and further by excluding, among the plurality of stop point candidates detected in the third step, one or more stop point candidates each satisfying a condition that the required time period estimated in the fourth step is larger than the target time period set in the second step;
• a sixth step of estimating the rear-end collision risk which is a risk of sustaining a rear-end collision assuming that the vehicle stops at each of the stop point candidates narrowed down in the fifth step;
• and
• a seventh step of setting, as the stop point, one of the stop point candidates narrowed down in the fifth step which is lowest in terms of the rear-end collision risk estimated in the sixth step.
