Abstract

A vehicle control device is capable of switching a driving state of a host vehicle between manual driving and autonomous driving, and determines whether or not another vehicle exists in a driver's blind area set in advance diagonally behind the host vehicle in a case where the driving state of the host vehicle is autonomous driving and when the host vehicle reaches a check timing set in advance. In addition, the vehicle control device executes the control in a case where it is determined that the other vehicle exists in the driver's blind area and when the other vehicle exists, which can be removed from the driver's blind area by the control of at least one of a vehicle speed of the host vehicle and a lateral position of the host vehicle.

First claim

What is claimed is:

1. A vehicle control device configured to be capable of switching a driving state of a host vehicle between autonomous driving and manual driving, the device comprising:
an electronic control unit (ECU) programmed to:
recognize a position of an other vehicle around the host vehicle;
recognize a travelling state of the host vehicle;
determine whether or not the host vehicle reaches a check timing set in advance, in a case where the driving state of the host vehicle is autonomous driving;
determine whether or not the other vehicle exists in a driver's blind area set in advance diagonally behind the host vehicle based on the result of the recognition by the ECU, in a case of the determination that the host vehicle reaches the check timing;
determine whether or not the other vehicle exists, which can be removed from the driver's blind area by control of at least one of a vehicle speed of the host vehicle and a lateral position of the host vehicle based on the result of the recognition by the ECU, in a case of the determination that the other vehicle exists in the driver's blind area; and
execute the control of the host vehicle based on the result of the recognition by the ECU, in a case of the determination that the other vehicle exists, which can be removed from the driver's blind area by the control.

2. The vehicle control device according to claim 1 ,
wherein, in a case where the determination is made that the other vehicle exists in the driver's blind area, the ECU is configured to determine whether or not the other vehicle exists, which cannot be removed from the driver's blind area by the control based on the result of the recognition by the ECU, and
wherein, in a case of the determination that the other vehicle exists, which cannot be removed from the driver's blind area by the control, the ECU is configured to control the lateral position of the host vehicle so as to be separated from the other vehicle which cannot be removed from the driver's blind area based on the result of the recognition by the ECU.

3. The vehicle control device according to claim 1 ,
wherein, in a case where the determination is made that the other vehicle exists in the driver's blind area, the ECU is configured to determine whether or not the other vehicle exists, which cannot be removed from the driver's blind area by the control based on the result of the recognition by the ECU, and
wherein, in a case of the determination that the other vehicle exists, which cannot be removed from the driver's blind area by the control, the ECU is configured to output a warning regarding the other vehicle which cannot be removed from the driver's blind area to the driver of the host vehicle.

4. The vehicle control device according to claim 2 ,
wherein, in a case of the determination that the other vehicle exists in the driver's blind area, the ECU is configured to determine whether or not the other vehicle exists, which cannot be removed from the driver's blind area by the control based on the result of the recognition by the ECU, and
wherein, in a case of the determination that the other vehicle exists, which cannot be removed from the driver's blind area by the control, the ECU is configured to output a warning regarding the other vehicle which cannot be removed from the driver's blind area to the driver of the host vehicle.
