Abstract

An evacuation travel assist apparatus includes a stop lane determination section that determines a stop lane and an evacuation place in the stop lane in which an own vehicle should be urgently stopped when the vehicle drive is detected to be in a state of being not able to drive the own vehicle properly, and a transverse position determination section that determines, as a stop transverse position, a position in a transverse direction of the evacuation place in the stop lane so as to ensure a space for the vehicle driver and passengers to get in and out of the own vehicle safely at a side of the own vehicle.

Claims

1. An evacuation travel assist apparatus comprising:

a driver-state determination section that determines whether or not a vehicle driver of an own vehicle is in a state of being able to drive the own vehicle properly;

an information acquisition section that acquires information regarding a state of the own vehicle and a state of a surrounding environment of the own vehicle;

a stop lane determination section that determines a stop lane and an evacuation place in the stop lane, in which the own vehicle should be urgently stopped based on the information acquired by the information acquisition section when the driver-state determination section determines that the vehicle drive is not in a state of being able to drive the own vehicle properly;

a transverse position determination section that determines, as a stop transverse position, a position in a transverse direction of the evacuation place in the stop lane so as to ensure a space for the vehicle driver and passengers to enter and exit the own vehicle safely at a side of the own vehicle; and

an evacuation travel control section that causes the own vehicle to travel to the evacuation place depending on the stop lane determined by the stop lane determination section and the stop transverse position determined by the transverse position determination section.

2. The evacuation travel assist apparatus according to claim 1, wherein, when an adjacent lane is present on one side of the stop lane, the transverse position determination section determines, as the stop transverse position, a position which is between the own vehicle and an edge opposite to the adjacent lane of the stop lane and in which a space for getting on and off the own vehicle is ensured.

3. The evacuation travel assist apparatus according to claim 1, wherein, when no adjacent lane is present on either side of the stop lane, and an obstacle to getting on and off the own vehicle is present on a left edge of the stop lane, the transverse position determination section determines, as the stop transverse position, a position which is between the own vehicle and a left edge of the stop lane and in which a space for getting on and off the own vehicle is ensured.

4. The evacuation travel assist apparatus according to claim 1, wherein, when no adjacent lane is present on either side of the stop lane, and no obstacle to getting on and off the own vehicle is present on a left edge of the stop lane, the transverse position determination section determines, as the stop transverse position, a position which is between the own vehicle and a right edge of the stop lane and in which a space for getting on and off the own vehicle is ensured.

5. The evacuation travel assist apparatus according to claim 1, wherein, when adjacent lanes are present on both sides of the stop lane, the transverse position determination section determines, as the stop transverse position, a center of the stop lane.
