Abstract
A yielding action assistance system for assisting a vehicle driver to take an appropriate action in yielding to a passing emergency vehicle. The yielding action assistance system comprises: a detector that detects a proximity of the emergency vehicle; an information collector that collects a road information and information about the emergency vehicle and other vehicle; a target zone determiner that sets and updates a target zone to pull over the vehicle based on the information about the other vehicle and the road; and a notifier that informs a driver about the target zone.
Claims14
A yielding action assistance system that assists a vehicle to yield to a passing emergency vehicle, comprising:
- a detector that detects a proximity of the emergency vehicle to the vehicle;
- an information collector that collects information about a road on which the vehicle travels, and information about the emergency vehicle and other vehicle travelling on the same road with the vehicle;
- a target zone determiner that sets a target zone to pull over the vehicle to clear the way for the emergency vehicle based on the information about the other vehicle and the road, and that updates the target zone continuously based at least on the information about the other vehicle;
- and
- a notifier that informs a driver about the target zone,
- wherein the information collector is configured to collect information about the emergency vehicle and the vehicle, and
- wherein the target zone determiner is configured to update the target zone until the emergency vehicle overtakes the vehicle.

- and
- a notifier that informs a driver about the target zone,
- wherein the target zone determiner is further configured to set the target zone in a shoulder of the road at a site at which a width of the target zone can be maintained wider than a width of the emergency vehicle, and a distance between the vehicle and the other vehicle to be stopped in an oncoming lane is maintained longer than a length of the emergency vehicle.

- a notifier that informs a driver about the target zone;
- and
- a first drive force controller that changes a drive force to increase a deceleration force when the driver pulls over the vehicle to the target zone indicated by the notifier,
- wherein the first drive force controller is further configured to:
- calculate a distance between the vehicle and the target zone;
- change the drive force when the distance between the vehicle and the target zone is reduced to a threshold value;
- detect a speed of the vehicle;
- and
- increase the threshold value with an increase in the speed of the vehicle.
